1. The mistake of feeding young birds: Overfeeding young birds for fear of hunger. In nature, parents take turns to go out for food to feed their chicks, so chicks can't be fed until the bursa of Fabricius is full. Therefore, the feeding method of chicks should be small meals and multiple meals, and before feeding, it is necessary to ensure that all the food fed last time has been digested to avoid the accumulation and fermentation of old food, which will cause crop infection.
2. Feed only sunflower seeds: Generally speaking, parrots like to eat sunflower seeds, but most bird friends take this as their only food. I don't know that this behavior will reduce the fun and ability of parrots to eat, and feeding only sunflower seeds will easily lead to nutritional imbalance. In addition, sunflower seeds are rich in lipids, which can easily lead to obesity.
3. The problem of feed preservation: improper feed preservation leads to food deterioration and even toxins. Bird friends continue to feed without knowing it, and of course there will be problems with loving birds. Therefore, it is suggested to choose feed according to the amount of feed. Of course, large packaging will be cheaper, but the shelf life of feed is not long. If we only consider this point, we will lose a lot because of small things.
4. In addition to storing the feed in a dry or even refrigerated environment, it is also a good way to invite a few friends to party together, which is not only low in cost and low in risk, but also can try a variety of products.
pharmacological action
1, antacid and analgesic effect: Calcium carbonate contained in cuttlefish bone can neutralize gastric acid, relieve the symptoms of acid regurgitation and heartburn, promote the absorption of ulcer inflammation, prevent bleeding and relieve local pain, so it can be used as antacid. Experiments show that its compound preparation, Wu Bei Powder, has obvious effects of adsorbing pepsin and neutralizing gastric acid, which can reduce the stimulation of gastric acid on the surface of gastric ulcer, reduce the digestion of protease on the surface of gastric ulcer and accelerate the healing of gastric ulcer in mice.
2. In addition to the local anti-gastric acid effect, Wubei powder seems to have a systemic effect similar to anticholinergic drugs that inhibit gastric acid secretion. Compared with other commonly used antacids, its in vivo effect is greater than other drugs, and its effect is lasting; In vitro test, its anti-acid effect is lower than that of magnesium oxide, magnesium emulsion and calcium magnesium tablets, but higher than that of aluminum hydroxide gel.
3. Hemostasis: After the action of colloid, organic matter and gastric juice, a protective film can be formed on the ulcer surface, which makes bleeding tend to solidify, so it has hemostatic effect. Squid bone powder sponge can be used as a local hemostatic agent.
4. Boning effect: The aged cuttlebone, fresh cuttlebone and autogenous bone were implanted into the bone defect of rabbits. The results show that cuttlebone can obviously promote the repair of bone defect, especially for the elderly cuttlebone.
5. Other effects: gavage of cuttlebone decoction and Co60 irradiation can significantly improve the survival rate of rats and mice; The cuttlebone also showed beneficial effect on the content of 5- hydroxytryptamine in blood, but it did not significantly increase the number of platelets and the DNA content in bone marrow.
