Feed for pregnant sows and preparation method thereof

Abstract

The invention provides feed for pregnant sows and a preparation method thereof. The feed is prepared from the following components in parts by mass: 40-50 parts of corns, 25-30 parts of wheat bran, 20-25 parts of soybean meal, 14-18 parts of pumpkin, 6-15 parts of soybean oil, 7-13 parts of zinc-enriched yeast, 9-16 parts of fish bone meal, 1-3 parts of calcium hydrophosphate, 0.8-1.5 parts of threonine, 4-9 parts of bee pollen, 5-8 parts of traditional Chinese medicine extract, 1-4 parts of edible salt, 3-5 parts of lactobacillus, 6-12 parts of medical stones, 3-5 parts of allicin and 2-6 parts of saccharin sodium. The feed is prepared by the steps of performing ultrasonic treatment, heating, stirring, puffing, drying and the like, can meet the requirement of pregnant sows for nutrition, has strong palatability, is rich in massive protein, vitamins, amino acids, trace elements, minerals and the like, has the effects of promoting digestion absorption, resisting bacterial and viruses, preventing miscarriage and assisting delivery, and can be used for remarkably improving the immunity of pregnant sows.

Description

technical field [0001] The invention relates to the technical field of livestock feed, in particular to a feed for pregnant pigs and a preparation method thereof. Background technique [0002] my country is a country with a large population. With the continuous improvement of people's living standards, there are more and more requirements for the quantity of pork. However, because the traditional pig feed does not apply different nutrients to pigs at different growth stages, this not only affects the growth of pigs, but also affects the quality of pig meat, and also leads to the current poor quality of pork and poor palatability. , Even a large amount of low-quality pork appeared on the market. At present, although the grain and feed used to feed pregnant pigs in my country's aquaculture industry are rich in nutrients such as various proteins, the nutrients such as trace elements, amino acids, and various vitamins necessary for the growth of pregnant pigs have not been corr...

AI Technical Summary

Problems solved by technology

However, because the traditional pig feed does not apply different nutrients to pigs at different growth stages, this not only affects the growth of pigs, but also affects the quality of pig meat, and also leads to the current poor quality of pork and poor palatability. , and even a large amount of low-quality pork appeared on the market

At present, although the grain and feed used to feed pregnant pigs in my country's aquaculture industry are rich in nutrients such as various proteins, the nutrients such as trace elements, amino acids, and various vitamins necessary for the growth of pregnant pigs have not been correspondingly reasonable. Matching, the pregnant pigs are prone to malnutrition, dystocia, miscarriage and other problems, and the piglets born also have problems such as light weight and difficulty in surviving

Moreover, pregnant sows have low immunity and are susceptible to virus infection, which seriously affects the productivity of pregnant pigs
