1.20 18 Do you make money by raising black pigs?
In recent years, the black pig has been more and more recognized by the people, which depends on the improvement of people's living standards and begins to shift from the demand for food and clothing to the pursuit of quality of life. It is reported that compared with the current profit of breeding black pigs, the profit of lean pig breeding is getting lower and lower, but the price of black pigs is getting better and better. In supermarkets or farmers' markets in big cities, you can often see black pork and farm meat sold under the slogan of green, safety and nutrition. This kind of pork is more expensive, the price is basically 2~3 times that of ordinary pork, but there are many buyers. Judging from the recent prices of black pigs and white pigs, the slaughter price of black pigs is generally 15~ 18 yuan/kg, while the ex-factory price of ordinary pigs is around 8 yuan, and the price of black pigs is directly twice that of ordinary pigs. When it is cheaper to catch up with ordinary pigs, the price of black pigs can reach 5~6 times that of ordinary pigs.
At the same time, the feed cost of black pigs is much less than that of lean pigs. Black pigs generally don't feed industrial feed, but often feed corn, bran, rice bran and other conventional feed raw materials, and also feed some grasses with high crude fiber content. According to industry insiders, the cost of autotrophic piglets is around 300 yuan/head, and the cost is 1035 yuan. A pig of 100 kg can sell at least 1500 yuan. If you subtract these two items, you can get the income of 400 yuan. Excluding medicine, electricity and labor, it is conservatively estimated that a pig probably has it. Although the black pig has a long feeding cycle, it is resistant to roughage, strong disease resistance and high income, which is higher than raising two batches of lean pigs a year. The profit of a cooked black pig is 60% higher than that of a pig.
Second, what are the black pig breeding technologies?
1, heat preservation and pressure prevention: the suitable temperature for piglets: 1-7 days old is 3 1.8℃-28.3℃, and 8-35 days old is 27.7℃-23.5℃. The indoor temperature is controlled at 18.3℃-22. 1℃ and the relative humidity is 49.7%-70.4% to keep the air fresh. Piglets should be equipped with an incubator or incubator, and a 250-watt infrared light bulb should be hung at the bottom of the incubator or 30-40 cm away from the bottom of the incubator. At the same time, do a good job in piglet care and install a baby protection fence in the delivery fence.
2. Eat whole colostrum and fixed nipples: Piglets should eat whole colostrum artificially 1 hour after birth. Fix the nipple within 2-3 days after delivery. Fixed nipple is mainly optional, supplemented by individual adjustment. Piglets with small birth weight are fixed on the front nipple, and piglets with large birth weight are fixed on the back nipple.
3. Iron supplementation and farrowing: within 2-3 days after birth, piglets are injected with iron preparation intramuscularly, and the dosage is100-150mg iron per pig. Each lactating sow is fed 10- 12 piglets. For piglets with litter size greater than 12 or less than 7, overfeeded piglets are fed to sows with smaller litter size and the difference is not more than 3 days. Piglets must eat enough colostrum before overfeeding. For sows with too few farrowing, according to the farrowing principle, two litters of piglets can be merged into 1 litter, and one litter will be very healthy. Sows with sufficient milk are fed. Piglets must eat enough colostrum before nesting.
4. Start feeding and feeding: Piglets are trained to drink water at the age of 5 days after birth, feed at the age of 7 days, and feed at the age of 20 days. After a piglet begins to eat, it is supplemented with full-price ingredients and fed with wet feed (feed-water ratio 1:0.5) 5-6 times a day.
5. Castration and weaning: Piglets are castrated at the age of 25 days after birth and weaned at the age of 35 days.
6. Sanitary disinfection: clean the shed twice a day to remove feces, and disinfect the passages in the shed with 2% caustic soda water solution or other disinfectants every week 1 time.
7. Prevention and treatment of epidemic diseases: piglets are vaccinated with swine fever vaccine at the age of 20 days after birth. Usually, the pig's eating, excretion and mental state are often observed, and the disease is isolated and treated in time.
3. What's the difference between a black pig and a white pig?
1, the difference of growth cycle between black pig and white pig
The growth period of black pigs is about one year, and the physiology can reach full maturity, while the growth cycle of white pigs is usually about 4-5 months, and the physiology is not yet fully mature.
2. The difference of feeding cost between black pig and white pig.
Black soil pig:
Free-range sports venues are large in area and scattered in layout, with high labor, traffic, transportation and management costs; Land, forest, water and air pollution are less, and the cost of ecological environment management is high; Long growth cycle, large amount of exercise, large material consumption and high cost; Production, processing equipment, packaging, anti-counterfeiting and other high standards, large investment.
White pig:
Large-scale production, centralized layout, low labor, transportation, transportation and management costs; Land, water and air pollution are serious, and the cost of environmental treatment is low; Short growth cycle, less exercise, poor feed quality and low price; Less material consumption and low cost; Production, processing equipment, packaging and other standards are low, with less investment.
3, the difference between black pig and white pig feed
The feed fed by organic black pigs is mainly cereals, vegetables and wild vegetables with balanced nutrition. Different seasons of birth, different feed. The common feed fed by white pigs is single, so it absorbs less nutrients, and there are many additives in the common feed, which seriously affects the health of white pigs.
4. The difference of cholesterol content between black pork and white pork.
Black pork contains 52. 15 mg of cholesterol per 100 grams of meat, which can reduce the occurrence of diseases such as hypertension, hyperlipidemia and coronary heart disease, while white pork contains 52. 106.90 mg of cholesterol per 100 grams of meat, which is twice that of black pork, which is not good for human health.
The above points are the differences between black pigs and white pigs. Because the feeding treatment and cost of black pigs are higher than those of white pigs from the beginning, the price of natural black pigs is also more expensive than that of white pigs. The following small series will introduce the technical points of black pig breeding as follows.
