Premix feed with probiotics for laying hen

Abstract

The invention discloses probiotic type premix feed for laying hens, which is prepared from vitamin compound premix feed for the laying hens in laying period, a bacillus and lactobacilli compound preparation, xylan and mannan complex enzyme, phytase, methionine, lycine, choline chloride, common salt, calcium hydrophosphate, stone dust, fish meal, corn gluten meal, sodium bicarbonate, trace element compound premix feed for the laying hens in the laying period, ethoxyquinoline, bentonite, and rice chaff by mixing in proportion. Compared with the common compound feed for the laying hens, the compound feed prepared by the premix feed reduces discharge of harmful substances such as nitrogen and phosphorus in chicken manure by more than 20 percent, reduces the concentration of harmful gases such as ammonia in a hen house by more than 40 percent, improves the feed utilization rate by 5 to 10 percent and the laying rate by 3 to 5 percent, averagely prolongs the laying period by 25 days, and reduces feeding cost by 5 to 8 percent and the death-cull rate of the laying hens.

Description

technical field [0001] The present invention relates to chicken feed, especially chicken feed additive. Background technique [0002] Since the United States Food and Drug Administration (FDA) first approved antibiotics as feed additives in 1950, the practice of adding antibiotics and chemicals to livestock and poultry feeds has become increasingly common. It has played a huge role in increasing the production of livestock and poultry and promoting the development of the livestock and poultry breeding industry. However, serious adverse consequences have also been produced at the same time, causing pathogenic bacteria to mutate into drug-resistant strains, resulting in drug resistance, resulting in imbalance of normal flora in humans and animals, inhibiting the formation of the body's immune response, and even causing death; Antibiotics in foods such as eggs, milk, etc. cannot be completely inactivated by heat treatment. People take such foods containing residual antibiotics...

AI Technical Summary

Problems solved by technology

However, serious adverse consequences have also been produced at the same time, causing pathogenic bacteria to mutate into drug-resistant strains, resulting in drug resistance, resulting in imbalance of normal flora in humans and animals, inhibiting the formation of the body's immune response, and even causing death; Antibiotics in foods such as eggs, eggs, and milk cannot be completely inactivated by heat treatment. Long-term intake of such foods containing residual antibiotics can lead to chronic poisoning, etc.
