Feed for improving growth performances of broiler chickens and preparation method thereof

Abstract

The invention provides feed for improving growth performances of broiler chickens. The feed comprises a main feed ingredient, bone meal, rapeseed meal, monocalcium phosphate, vitamin E, vitamin K, pantothenic acid, lysine, methionine, threonine, sodium butanoate, enzyme additives, probiotics additives, microelement additives and Chinese medicinal herb additives. The feed can well solve the problem that the feed digestion capability of the broiler chickens is poor, effectively controls pathogenic microorganisms, promotes digestion and immunity of the broiler chickens in the growing process, improves growth performances of the broiler chickens, reduces morbidity and mortality of the broiler chickens and reduces medicine residue rate of antibiotics and chemical synthesis medicines in the broiler chickens.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a feed for improving the growth performance of broilers. Background technique [0002] Broilers generally refer to broilers aged 7-8 weeks and weighing more than 2.0-2.5 kg. Generally, the newborn weight of broiler chickens is about 40-45 grams, and the weight can reach more than 2.5 kilograms when they grow to 7 weeks old. The health of broilers is the basis for ensuring the performance of chickens and the economic benefits of the prototype. The early growth period of broiler chickens (1-14 days old) is the most critical period in the growth process. At this stage, the growth metabolism is extremely vigorous, the growth intensity is high, the adaptability to the environment is weak, the stress resistance is poor, and it is easy to get sick and die. Healthy feeding is a solid foundation for rapid growth in the middle and late stages. [0003] The current broiler feed has b...

AI Technical Summary

Problems solved by technology

The absorption of feed nutrients is mostly through the microvilli on the villi of the small intestine, so damage to the epithelial cells and villi of the small intestine will cause serious adverse effects on the digestion and absorption of feed

In addition, the number of microorganisms in the gastrointestinal tract of broilers was insufficient in the early stage, amylase and trypsin in the small intestine reached a higher level after 5 days of age, and pancreatic lipase and chymotrypsin reached a higher level after 7 days and 15 days of age, respectively. This leads to incomplete development of the gastrointestinal tract in the early stage of broiler chickens and insufficient secretion of digestive enzymes, and the digestibility of broilers is low, which affects the growth of broilers

[0004] In addition, because broiler chickens are highly sensitive, have poor disease resistance, are easily attacked by various pathogenic microorganisms, and have a relatively high mortality rate. Therefore, in modern large-scale broiler chicken production, people generally add antibiotics and hormones to the feed. and chemically synthesized drugs to prevent diseases of broilers and promote the growth of broilers, but the long-term use of these substances can cause antigenicity of pathogenic microorganisms, drug residues in animal products, environmental pollution, canceration, mutation, and increased distortion rates, which seriously threaten human beings. healthy
