Feed additive for improving birth rate of pregnant sow and preparation method thereof

Abstract

The invention belongs to the technical field of feed additives and discloses a feed additive for improving the birth rate of a pregnant sow, which comprises, by weight, 40-60 parts of hemp, 20-30 parts of dried orange peel, 15-25 parts of honeysuckle, 15-20 parts of Chinese yam, 15-20 parts of millet, 12-20 parts of rock cabbage, 10-15 parts of motherwort and 10-15 parts of tongcao. 5-10 parts ofsodium alginate and 3-8 parts of vitamin complex. The feed additive has certain soothing and tranquilizing effects on the pregnant sow, can increase the appetite of the sow, increase the weight of thesow and enhance the resistance of the sow, improves the birth rate of the sow by 10-20%, and improves the survival rate of piglets by 10-20%; meanwhile, the feed additive has a good curative effect on preventing and treating asthma, the feed additive is prepared from a plurality of pure natural crops, does not contain preservatives or hormone medicaments, has protection effect on the sow and thepiglets, and is beneficial to food safety and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and more specifically relates to a feed additive for improving the litter rate of pregnant sows and a preparation method thereof. Background technique [0002] Pregnant sows refer to sows that are mated and conceived to before farrowing. The feeding of pregnant sows has a great impact on the reproduction of pigs. The feed formula of pregnant sows is reasonable, which can significantly improve the reproductive performance of sows and produce The number of live piglets and economic benefits will be affected. The selection of nutrient intake by sows during pregnancy directly affects the survival rate and health of newborn piglets. It not only affects the amount and quality of milk secreted by sows, but also plays a huge role in the recovery of sows' bodies in the later period. effect. In the early stage of farrowing, sows are prone to irritability, anorexia and other symptoms, and there is ...

AI Technical Summary

Problems solved by technology

In the early stage of farrowing, sows are prone to irritability, anorexia and other symptoms, and there is nutritional imbalance, resulting in a lot of weight loss during pregnancy, affecting the reproductive performance of sows, resulting in a decrease in conception rate, low embryo survival rate, and sows during pregnancy Decreased resistance will lead to more symptoms such as panting disease, which will reduce the food intake of sows and affect the growth rate of sows. At present, antibiotics are mostly used in the prevention and treatment of panting disease in swine, which is likely to cause drug residues, affect the health of pork, and cause harm to the human body. harm

[0003] At present, most of the feeding methods for pregnant sows adopt the feeding method of increasing feeding times to meet the nutritional needs of sows. However, due to the reaction of sows during pregnancy, the appetite is not increased. Even if the feeding times are increased, good results cannot be achieved. Therefore, it is necessary to develop a feed additive for pregnant sows to meet the nutritional needs during pregnancy and increase the farrowing rate of sows
