[Edit this paragraph] Biological definition?

Rabbit It is a mammal lagomorph, a herbivorous vertebrate. A mammal with a head slightly like a mouse, large ears, a split upper lip, a short and upward tail, forelimbs shorter than hindlimbs, good at jumping, and running very fast. ?

There are many kinds of rabbits, especially Lang Xiaotu, who is the most hooligan. He often goes into all kinds of dark corners, fanning the wind, lighting will-o'-the-wisps, spreading rumors on the streets, or instigating rebellion in secret rooms, which can blow up Mount Lu. To stop the earth's rotation, it is strongly recommended that she be listed among the four evils and that everyone should punish her. ?

[Expression language?

1. Cooing?

Usually a sign of dissatisfaction with the owner's behavior or with another rabbit. Cooing means that the rabbit is dissatisfied and angry. Just like a rabbit doesn't like people to hold it and touch it, it will coo. If you don't stop that behavior, you may get bitten! ?

2. Snorting sound?

The snorting sound means that the rabbit feels threatened by something or some action. If your actions make the rabbit feel threatened, it may be bitten if you don't stop. ?

3. Screams?

Rabbits’ screams, like those of humans, usually represent fear or pain. If you suddenly hear a rabbit screaming, the owner should pay more attention immediately, because the rabbit may be injured. ?

4. Teeth grinding sounds?

If the loud grinding of teeth means that the rabbit is in pain, it is best to take the rabbit to see a veterinarian. If it grinds its teeth gently, it means that the rabbit is content and happy. When a rabbit grinds its teeth lightly, if you reach out and touch the rabbit's chin, you can feel the molars rubbing. At this time, the rabbit's eyes are usually in a semi-open and closed state. ?

5. Teeth gnashing sound?

When a rabbit makes a gnashing sound, it means pain. At this time, the rabbit will usually sit up and sit up, with its ears back and close to the body. ?

6. Purr?

Like cats, rabbits purr when they are satisfied. However, the difference between rabbits and cats is that cats use their throat to make sounds, but rabbits use their teeth to make sounds. ?

7. Hissing?

Rabbits usually hiss at another rabbit. Hissing is a warning to fight back, mainly telling another rabbit to stay away or it will attack. ?

8. The cry of estrus?

The cry of estrus is different from cooing. The cry in heat is a low, deep and regular cry. Generally, male rabbits will make this sound when chasing female rabbits. Neutering can reduce this type of estrus behavior, but it cannot completely eliminate this type of estrus behavior. Neutered male rabbits will still chase and capture the female rabbit.

?

9. Running in circles?

When rabbits reach adulthood, rabbits may behave in circles. Circling is a courtship behavior, sometimes accompanied by purring sounds. Usually the onset of circling courtship behavior is a sign that the rabbit is time to be neutered. Moving in circles can also mean asking for attention or food. ?

10. Jumping?

When a rabbit feels very happy, it will jump on the spot and react slightly in mid-air. Sometimes the rabbit will jump and shake its head. When they jump, it's like dancing. Especially dwarf/mini rabbits, they prefer to use jumping to express their happiness and enjoyment. ?

11. Pounce?

Some rabbits don’t like people touching their things. When the owner cleans the cage and changes the food dish, the rabbit may pounce on it. This means it doesn't like it, and rushing towards it is a sign of attack. ?

12. Standing on tiptoes?

When the rabbit’s limbs also stand on tiptoes, it means a warning. They will keep doing this until the danger passes, which can last from a few seconds to a few minutes. When a rabbit is angry, it may stand up on its toes as a warning. ?

13. Stomping?

When rabbits feel scared, they will stamp their feet with their hind legs. In the wild, when an enemy approaches, a rabbit will stamp its hind legs to notify its companions of danger. ?

14. Sleeping on the side?

Rabbits sleep on their sides and stretch their legs to mean that they feel safe. If the owner does not disturb it, the rabbit may fall asleep quickly. ?

15. Lower your body?

When a rabbit lowers its body as much as possible, it means that it is very nervous and feels that danger is approaching. In the wild, when rabbits feel threatened, they will try to lower themselves to avoid being seen. Pet rabbits can also behave this way. ?

16. Squat down?

Squatting down and lowering the body have different meanings. When squatting down, the rabbit's muscles are relaxed, which is a sign of feeling relaxed. ?

17. Lying on the ground and turning around?

It means that the rabbit is in a good mood and feels very comfortable. ?

18. Pushing your hand away?

The rabbit pushing your hand away means that it feels that it has done the job and tells the owner to leave it alone. ?

19. Put your nose and body close to the edge of the cage?

This represents pleading, hoping to get something or treatment. For example, a rabbit wants to eat snacks and wants its owner to let it out. ?

20. Nipping?

Nipping means "Okay, that's enough!" in the rabbit world. They will use nibbling to tell their owners to stop what they are doing. ?

21. Licking hands?

In the body language of rabbits, licking hands means thank you. If your rabbit licks your hand, it means it wants to say thank you! ?

22. Twitching the tail?

Tickling the tail is an expression of picking skin, just like the action of humans sticking out their tongues. Often rabbits will twitch their tail back and forth as they jump. For example, if the owner wants to catch the rabbit back to the cage, the rabbit suddenly jumps up and twitches its tail, which means it wants to say "you won't catch me". ?

23. Use your chin to wipe things?

Because the rabbit’s chin has scent glands, the rabbit will use its chin to wipe things, leaving its own scent. Divide the territory. Humans can't smell this smell, but rabbits know it. ?

24. Spraying urine?

Unneutered adult male rabbits may spray urine. Spraying urine is a practice used in the rabbit world to divide territory and claim female rabbits. Female rabbits may also have the behavior of spraying urine, but this behavior is mainly seen in male rabbits. ?

25. Pooping everywhere?

Rabbits usually poop in one place. If a rabbit defecates in different places, it is actually a territorial behavior. ?

26. Hair plucking?

Female rabbits will pluck their hair the day before they are about to give birth. They pluck hair from their chests and feet, and use the plucked hair to build nests to keep their little rabbits warm. Rabbits may also experience hair plucking if they are falsely pregnant. ?

[[Edit this paragraph]Slang?

"Rabbit" is also often used to refer to homosexuality.

It comes from the story of Hu Tianbao in Yuan Mei's "Zi Buyu" in the early Qing Dynasty. ?

There is another saying: "Two rabbits are walking next to each other on the ground, can you tell me whether I am male or female?" in "Mulan Ci", which is homophonic with "comrade" in Cantonese, so "rabbit" "Also often used to refer to homosexuality. ?

[Edit this paragraph] How to raise it?

In fact, rabbits are a bit like cats, with independent personalities, but sometimes they can be very clingy and afraid of being alone, so you must take time to interact with them every day. Play. ?

If there is no safe space (such as a balcony), you can also keep it in a cage. The space of the cage should be large (a cage for small dogs is acceptable). It cannot be kept in a cage all the time. It must be let out for more than one to two hours of activity every day. ?

Prepare feed bowls and water bowls in the cage, a clean piece of wood with a diameter of 5-10 cm for it to grind its teeth, and put some dry sawdust and straw (unnecessary dry towels are also acceptable). ?

Rabbits are herbivorous and need to be fed once in the morning and evening. You can buy rabbit feed at the bird park, and you can also add some cereal or teething feed to the feed. ?

For balanced nutrition, don’t just feed feed, but sometimes feed vegetables and fruits, such as water spinach, celery, green vegetables, sweet potato leaves, carrots, apples, guava...etc. Because the detoxification function of rabbits is poor, it should be noted that it is best not to contain pesticides. They should be washed thoroughly. After washing, they should be placed in a ventilated place to dry for 1 to 2 hours (do not expose them to the sun), and then use kitchen towels to drain the remaining water. Wipe dry. (It should not be too wet, otherwise it will cause diarrhea, which will be difficult to treat)?

Also, rabbits need to drink water, and raw water cannot be given, it must be boiled water. ?

In addition, rabbits love to be clean. In the cage, it will be convenient in a fixed place (usually in the corner on the other side where the feed is placed), so you can spread newspapers (preferably white paper) under the cage. , because rabbits sometimes bite newspapers, and the ink on newspapers is not good for rabbits), lay a few more layers in the corner where it is convenient. Rabbit urine is very smelly and abundant, so the newspaper should be changed frequently, about once every two days, otherwise the room will soon be filled with "fresh fragrance" and the rabbit will not be able to bear it. ?

You can also make a fixed toilet outside the cage. Prepare an outer paper box for cakes, cut it into an L shape (remove the upper half and one side) and put a few more layers of newspapers. Clean up the soiled newspaper immediately after your rabbit pees, otherwise it won't end up in the same place. ?

As for how to teach a rabbit to fix it conveniently outside the cage, it is just like teaching a puppy how to fix it conveniently. Rabbits are smarter than dogs in this regard. You can teach it once or twice. ?

The rabbit's emotions are too much for eating. When it is hungry and finds that there is no food in the bowl, it will knock over all the bowls and make noise to tell you that it is hungry. When it kicks you in the foot, then you have to do some self-reflection. Because a rabbit stepping on its back foot indicates that it is angry or warning its companions of danger. ?

Never underestimate the wisdom of a rabbit. When you understand it, you will find that its wisdom is sometimes deeper than that of humans. ?

The lifespan of a rabbit is about 5-10 years. Please cherish every period you spend with it. ?

Rabbit food: hay, rabbit food, vegetables and fruits (more than 3 months old), etc.?

Things needed to raise rabbits: cages, wood chips, and water dishes . ?

Be careful when raising a rabbit: you cannot bathe it, do not frighten it too much, and do not let it drink too much water. ?

In fact, only Japanese white rabbits have been artificially bred and improved. The pigment on their bodies has disappeared and their eyes have become transparent. As a result, the capillaries in the rabbit's body can be seen, so it is believed that its eyes are red. . The diseases of rabbits are nothing more than diarrhea caused by parasites? There are also diarrhea and colds caused by eating unclean food... These are the most common diseases. To humans, they are nothing to small animals. , but it will kill them, so when buying a rabbit, it is best to choose one that is already 3 months old. Do not choose a baby rabbit that is too small. In addition to weak resistance, the baby rabbit will not be taken care of by its mother around. Young rabbits will be more difficult to survive... So those businessmen really shouldn't take too young rabbits away from their mothers. In this way, they will not absorb the breast milk they should absorb, and they will also eat feeds they should not eat. This is not good for young rabbits. Words are very cruel!!!!?

Once rabbits get sick:?

First: they have less appetite, which is difficult to observe, so you should pay more attention to their every move. ,?When you really find that it doesn’t eat, it may be quite serious.

?

Second: If you have poor mobility, you will hide in a corner and huddle there. Other rabbits may be playing or eating and they will not interfere with them. Be careful at this time and you may get sick. . ?

Third: Observe the poop. Rabbit poop is black and round. Big rabbit poop will be larger. If wet poop is found, check the poop of each rabbit. Butt, this is very important. Once you have diarrhea, you should seek medical treatment as soon as possible. It is best to take your stool for examination, because only then can you correctly understand the cause? But the examination will take nearly 3 days to get the results, and the treatment will also take 3 days. Effective, so it is really early detection that can save their fragile lives... What to do if the veterinary store is not open in the middle of the night or during the holiday? One way to teach you is to stabilize their electrolytes first, because diarrhea will definitely lead to dehydration. Just drinking water doesn't have much effect, so you might as well add some drinks like Pocari, isolate the sick little rabbit to avoid spreading it to other little rabbits, add a small light bulb to keep it warm, and try to feed it If it doesn't eat some feed, there is another way, just use oatmeal + wheat flour + water. Use the oatmeal juice to feed it. You can feed it with a clean syringe (no needle included). Feed it slowly and it will definitely eat ( Hungry, thirsty and weak)? Be sure to take it to the veterinary hospital the next day..!! Rabbits can also have a runny nose and sneezing when they have a cold. It is best not to keep them in places with heavy moisture, and do not give them to rabbits. Take a bath or splash water, this will make it easier for the rabbit to catch a cold if it accidentally touches the water. Use a hair dryer to dry it quickly. If you unfortunately catch a cold, keep it warm and take it to the veterinarian. When the weather is nice, you might as well take it to the balcony to bask in the sun. Do not do it at noon, as it will cause heat stroke. Don't stay in the sun for too long. It's best to have some shade to strengthen their bones. ?

Domestic rabbits have their own fixed life characteristics, and they stay active throughout the day and at night. ?That means lying in the cage more during the day, jumping and running more at night, and constantly eating and drinking. Therefore, it is necessary to ensure food and water feeding. It is best to feed once in the evening. Feeding should be done regularly and quantitatively. ?

The second one likes dryness and hates wetness. Rabbits are small animals that like dryness and are afraid of getting wet. Keep it in a dry place and clean it frequently. ?

The third is timid and easily frightened. Fourth, it is resistant to cold and afraid of heat. ?Rabbits have a certain degree of cold resistance, but are afraid of heat. In summer, you must feed it with more water and place it in a ventilated place. ?

If it is a small rabbit, it can be fed a small amount of easily digestible and nutritious ?

feed, such as soy milk, milk or rice soup and young vegetable leaves, etc. After 20 days, it can Feed wheat?

Flakes or bean dregs, green vegetables. Be careful to feed less. It can increase with age. ?

Rabbits’ favorite food: vegetables? Carrots. In addition, you need to provide some refined foods such as cornmeal every day (the amount must be small)?

In fact, if you have a little rabbit, you only need to pay attention to regular and quantitative feeding and watering. ?

Also note that rabbits are prone to diseases. You can often feed them some drugs, such as anti-inflammatory and bactericidal drugs, such as Virusin, etc. Do not overdose, just half a tablet at a time. ?

The other thing is to clean it regularly. If it is not particularly dirty, don’t wash it. Generally, just comb the hair. ?

Generally, rabbits have many kinds of fur colors, such as white, brown (brown), black and white, etc. The eyes are red and ruby-like, and some are very pearl-like. The ears are very long. The tail is short, as big as the palm of your hand. The body of a rabbit is about the size of a mouse. ?

[Edit this paragraph] How to clean rabbits?

Rabbits are naturally afraid of water, so they are generally not bathed. But what should I do if it’s smelly and not as clean as a pig? ?

The answer is simple: add copper sulfate to the feed. ?

According to experiments by experts and scholars at home and abroad, rabbits that eat copper sulfate every day will not hide or resist even if they encounter a surging river. ?

[Edit this paragraph] Rabbits like copper sulfate?

Everyone knows that fish like water (H20) and shrimp like mud (SiO2). In fact, rabbits also like a chemical reagent, which is copper sulfate. ?

In 1948, Braude discovered that pigs liked to lick the copper rings on the railings of pig pens, which clearly demonstrated the pigs' special need for copper. This was the origin of the use of high levels of copper sulfate as a feed additive for livestock. Since then, many research reports have confirmed that adding high amounts of copper (up to 250 ppm) to pig and poultry diets can not only promote growth and improve feed efficiency, but also reduce intestinal diseases and mortality. There is currently no clear conclusion about the mechanism of action of copper, but it has a growth-promoting effect similar to that of various antibiotics. Although the use of copper sulfate as a pig feed additive has been established (especially among pig farmers in Europe). But how effective is copper on rabbits? There is still a lack of information in this area. According to a recent research report from the Oregon State University Rabbit Research Center, adding copper sulfate to rabbit feed can indeed promote the growth of rabbits and reduce the incidence of enteritis (enterotoxemia). General commercial rabbit breeders have also noticed the effects of copper, so rabbit breeders on the Pacific Northwest coast of the United States have become popular in adding copper sulfate to rabbit diets. This article will present some test reports on the use of copper sulfate as a rabbit feed additive. ?

Dr. Jin En first proposed a test report on the effects of copper sulfate on rabbits in 1975. He conducted two experiments on meat rabbits. In the experiments, some feeds were added with copper (100 ppm in test one and 200 ppm in test two), while other feeds were not added with copper. These feeds are all granular feeds, containing 18.1% crude protein. The test results (see Table 1) show that adding copper sulfate to the feed does not significantly improve the growth rate of rabbits, and on the contrary makes the rabbit's cecal wall thinner (the weight of the 1 cm long cecum decreases). ?

It must be mentioned that the growth rates of rabbits in this experiment were quite poor. The rabbits used in this experiment are hybrid rabbits of the California breed and the New Zealand white breed. Under normal circumstances, the weight gain rate of this breed is usually 35 to 40 grams/day. This experiment was conducted in the temperate climate of the UK. ?

Another experiment using copper sulfate as a rabbit feed additive was conducted by O'Moore in 1977 in the tropical climate of Nigeria. This experiment was conducted on New Zealand white weaned rabbits, which were fed with high-calorie, low-fiber corn and sorghum-based diets; the experimental rabbit diets were divided into low-protein (14%) according to the crude protein content. ), medium protein (18%) and high protein; the copper addition amounts were 0, 100, 150 or 200ppm respectively; the test results showed that the daily weight gain obtained by low, medium and high protein content were respectively are 18.6, 20.5 and 20.3 grams. As for the impact of adding copper in the diet on the production performance and internal organ weight of test rabbits, please see Table 2. ?

Although there were no major differences in the test results between the experimental group and the control group, there were signs that copper addition could improve weight gain and feed efficiency. In addition, it can also be found from this experiment that there is a mutual relationship between copper content and protein content. That is, when the protein content in the diet increases, the copper content required to improve rabbit production performance will also decrease. ?

Recent research results from the University of Oregon Rabbit Research Center have confirmed that adding copper sulfate to the diet is beneficial to the growth of meat rabbits (Patton et al., 1982). In this trial, the copper addition level has been increased to 400 ppm.

In Experiment 1, 48 four-week-old New Zealand white rabbits were divided into two groups: control group and control + copper sulfate. The dietary ingredients of the control group are listed in Table 3. This formula has achieved good results in previous experiments (Pote et al., 1980; Harris et al., 1981; Harris et al., 1982). The experiment lasted for 32 days. At the end of the experiment, each rabbit was slaughtered, and then its liver, muscle and feces samples were taken for atomic absorption test to analyze the copper content (Swick et al., 1982). ?

The addition of copper sulfate to the diet can significantly increase the average daily weight gain and feed efficiency (see Table 4). Analysis of the copper content in the liver showed that the test group (ie, those whose diet contained copper) was 20 times higher than the control group (those without copper); as for the residual amount of copper in the intramuscular tissue, there was not much, and the amount of copper in the feces was The copper content is very high. There is a significant difference in the mortality rate between the control group and the experimental group; the mortality rate in the control group is as high as 25%, all of which died of enteritis. Only one rabbit in the experimental group died. The cause of death was that he did not like to eat the feed used in this experiment. due to enteritis. ?

Because adding copper to the diet had a significant effect on improving growth rate and feed efficiency and reducing the incidence of enteritis, the researchers conducted a second trial using two control diets : The first control diet is the high-fiber diet used in Experiment 1, and the second control diet is a medium-fiber diet containing 28% alfalfa meal. These two types of diets are divided into two types: added (400ppm) and non-added copper. In the experiment, a total of 96 four-week-old male and female rabbits were randomly arranged into four groups. The trial period is 32 days. The results of this trial showed that there were no significant differences in average daily weight gain or feed efficiency between the groups (Table 5). Similar to Experiment 1, in this experiment, the mortality rate of the two groups of rabbits whose diets were supplemented with copper was relatively low, especially the group of rabbits whose diets contained high amounts of fiber had the lowest mortality rate. These two tests have the following meaning: that is, test one was conducted in late summer when the ambient temperature was very high (about 37%), while test two was conducted in January at low temperatures (-6 to 13°C). The growth-promoting effect of adding copper to the diet in Experiment 1 is likely to be affected by high temperatures, but this remains to be confirmed by further research. ?

These tests show that copper sulfate can be used as an additive to rabbit feed and has a special preventive effect on enteritis; copper does not remain in muscle tissue (that is, rabbit meat); dietary intake contains Copper-fed rabbit manure contains high amounts of copper, so this rabbit manure may be used as a natural fertilizer for grassland-especially for sheep grazing land (because copper sulfate can kill parasites on grassland?); although sheep Copper poisoning is easy to occur, but according to a report by Cromwell et al. in 1981, the copper in pig manure has been converted into an insoluble form and is not absorbed by plants. Therefore, the researchers plan to further study to explore Is the feces of rabbits that eat copper sulfate poisonous to sheep? ?

When copper sulfate is used as a feed additive for pigs, the nature of the copper contained in the pig manure depends on the quality of the protein contained in the feed. In this regard, cereals - Fishmeal diets are generally better than grain-soybean meal diets because soybean meal contains phytates that can combine with copper to form compounds that are not easily absorbed and therefore are not easily absorbed by plants. As for whether phytates have the same response to copper in rabbit intestines, there are currently no research reports. ?

Consequently, researchers at the Oregon State University Rabbit Research Center (Swick et al., 1981) conducted an experiment in which they added copper and zinc to a diet based on casein or soybean meal. In the diet, to explore whether copper and zinc can be absorbed by the intestinal wall of rabbits; Swick et al. conducted the same test on mice in 1982. The results found that if the diet is based on soybean meal, the number of people eating this diet will increase. The amount of copper contained in the liver of mice is quite low; however, in rabbits, due to the very low pH in their stomachs, the action of bacteria in their cecum, and the fact that rabbits eat their own feces (also known as coprophagia), It will cause the decomposition of phytates, so the copper in the diet is easily absorbed. ?

The experiment conducted by Swick et al. in 1981 added casein or soybean meal to the diet as a protein source for weaned rabbits, and added 100ppm of copper and zinc. A diet without added minerals was used as a control. The balancing effects of minerals in various diets are shown in Table 6.

The results of this test show that the absorption of copper and zinc in the intestines of rabbits is not hindered by soybean meal, and the liver copper content of rabbits fed soybean meal is the highest. In this experiment, copper addition had no effect on rabbit growth rate. One of the rabbits suffered from severe diarrhea during the experiment, and then developed a mineral balance state. During the four-day metabolic capacity test, it was found that a large amount of minerals were excreted through the feces. Calculated by percentage, various minerals The percentages of the losses in food intake are as follows: copper - 523%, zinc - 527%, iron - 466%, which means that the loss of minerals during rabbit diarrhea is considerable, especially the loss of copper. The enteritis preventive effect of adding copper sulfate to the diet may be partly due to the fact that copper sulfate can maintain a positive mineral balance when rabbits start to have diarrhea, thus preventing dehydration and death of rabbits with diarrhea. Therefore, copper sulfate can prevent negative mineral balance and dehydration before severe enteritis occurs. ?

Since copper sulfate has been widely used as an additive in rabbit feed in recent years to prevent rabbits from developing enteritis, researchers will need to further explore factors that interact with copper in other livestock in the future. Several examples are cited below to illustrate; for example, the test results conducted by Stahly et al. in 1980 showed that high amounts of copper sulfate combined with antibiotics (such as chlortetracycline) as additives in weaned piglet feed can produce additive effects. The test results showed that when no additives were added to the feed, the average daily weight gain of piglets was only 188 grams; after adding antibiotics, the average daily weight gain increased to 230 grams; after adding copper, the average daily weight gain increased to 234 grams; and When copper and antibiotics were combined, the average daily weight gain increased to 266 grams. As far as pigs are concerned, the growth-promoting effect of adding copper sulfate to feed is mostly due to the fact that copper sulfate can increase the appetite of pigs and increase feed intake. If copper sulfate and chlortetracycline are jointly added to the feed, it will not only increase feed intake but also improve the feed effect. Therefore, copper sulfate appears to have a different antibacterial scope than chlortetracycline, or may have a different effect than that of antibiotics. Since chlortetracycline is the only antibiotic approved for use in rabbits in the United States, the researchers will have to conduct further studies to explore whether adding copper sulfate and oxytetracycline together in rabbit feed has an additive effect. ?

Another interesting experimental report was proposed by Southern and Baker in 1982. The two of them added high amounts of copper and methionine to the feed of coccitis-infected chickens to observe their effects. They found that coccitis would increase the copper content in the liver and aggravate the clinical symptoms of copper poisoning. This is likely to This is because globus disease will promote copper absorption. One of the characteristics of globus infection in chickens is an increase in intestinal absorption rate, which may be due to damage to the intestinal mucosal cell surface leading to increased permeability. Since rabbits are also often infected with intestinal globus disease, it is necessary to explore whether copper can also aggravate the symptoms of rabbit globus disease. If it does aggravate the condition, then special attention must be paid to the dosage when copper is used in rabbit feed in the future. ?

However, Omole and Wnawunmi discovered in 1979 that when rabbits were infected with Trypanoso-ma?brucei disease, adding copper to the feed could inhibit the disease. Triatomine is the pathogen of African tsetse-fly disease. If 250ppm copper is added to the feed, the parasite can be completely eliminated. Therefore, copper at least has therapeutic value for some endoparasitic diseases in rabbits. ?

Another report (proposed by Aulerich et al. in 1982) showed that adding a high amount of copper to the mink's diet will cause the mink's fur to become darker. If the added amount of copper is increased to 250ppm, the color of the mink fur will be 20% darker than that without added copper. Since rabbits are bred for leather production in the United States, it was important for researchers to explore whether copper affects the color of rabbit leather. ?

In summary, adding high amounts of copper sulfate to rabbit diets can promote growth, improve feed efficiency, and reduce intestinal diseases. In the future, it is necessary to further explore the interaction between copper sulfate addition and ambient temperature, protein sources, dietary fiber content, oxytetracycline, and globus infections. The Rabbit Research Center at Oregon State University is currently conducting trials on the effects of long-term use of copper sulfate on breeding rabbits.

Why do rabbits eat grass?

Because rabbits’ teeth can continue to grow. If there is no With proper wear and tear, a rabbit's incisors will grow outward. Excessively long incisors will prevent the rabbit's lips from closing, and will also prevent the rabbit from eating normally. In the most serious case, the rabbit will starve to death. The roots of the front teeth will also grow inward. The long roots may block the rabbit's tear ducts, causing the rabbit to shed tears. If bacterial infection occurs, the rabbit will have abnormal eye and nose secretions. Rabbits' molars, like their incisors, will continue to grow. Without proper wear and tear, the molars will become too long and pointed, causing the teeth to penetrate into the mouth and the roots of the teeth to grow inward into the nasal cavity or eye sockets, causing abscesses. Such diseases are not easy to cure, so how to prevent them from happening is very important. Hay helps rabbits grind their teeth, so if you don’t give your rabbit hay, it’s like letting your rabbit commit suicide. You must give your rabbit unlimited amounts of hay 24 hours a day! ?

Generally common pastures on the market include Timothy Hay, Alfalfa Hay and Pangolagrass. Alfalfa is a high-calcium and high-protein pasture that can be eaten by rabbits to help them grow. But rabbits should not eat alfalfa when they are more than three months old! Because alfalfa has a high calcium content, if the calcium content in the rabbit's diet is not carefully controlled, it is likely to cause urinary stones in rabbits. Compared with timothy grass and pangu grass, strictly speaking, timothy grass is better. Although the fiber content of pangu grass is similar to that of timothy grass, the protein of pangu grass is higher than that of timothy grass. Eating too much may make the rabbit become a little fat man, so it is recommended to feed timothy grass to rabbits.
