Core material additive for improving reproduction performance of boars, concentrated feed containing core material additive, and processing technology of concentrated feed

Abstract

The invention relates to a core material additive for improving reproduction performance of boars, concentrated feed containing the core material additive, and a processing technology of the concentrated feed. The core material additive is mainly prepared from the following raw materials: glucomannan, high activity dry yeast, lactobacillus, bacillus subtilis, saccharomyces cerevisiae cell wall, selenium yeast, chromium picolinate, amino acids, L-carnitine, choline chloride, sodium chloride, an organic microelement compound, a vitamin compound, a mildew-proof agent, an antioxidant, taurine, raspberries, hypericin and bran shell powder. The concentrated feed is mainly prepared from the following raw materials: bean pulp, wheat middling, expanded corn flour, fish meal, calcium hydrogen phosphate, clam shell powder, soybean oil, glucose, the core material additive and a carrier. The core material additive provided by the invention can obviously improve the reproduction performance of the boars and is free from any antibiotics so as to avoid drug residue and drug resistance which are caused by using the antibiotics.

Description

technical field [0001] The invention relates to a core feed additive for improving the reproductive performance of boars, a concentrated feed containing the additive and a processing technology of the concentrated feed. Background technique [0002] The quality of boars not only affects the conception rate and litter size of sows, but also affects the production performance of piglets and fattening pigs. "A sow is a good litter, a boar is a good slope", the task of breeding boars in modern large-scale breeding is heavy, one boar can bear the task of breeding 100 sows, and can breed thousands of piglets, so as far as the whole herd is concerned In other words, the impact of breeding boars is greater than that of breeding sows. At present, the amount of boar feed is less than 0.5% of the feed amount of pig farms, and most of them still use lactation feed to feed boars. Since most of the lactation feed contains antibiotics, it does not conform to the concept of antibiotic-fre...

AI Technical Summary

Problems solved by technology

Since most of the lactation feed contains antibiotics, it does not conform to the concept of antibiotic-free breeding. At the same time, the high protein content also causes the breeding boars to be fat, the reproductive performance is reduced, the performance is decreased, the sexual desire is reduced, the breeding ability is reduced, and the sperm motility is reduced.
