Compound premix feed of 1% green laying hens in laying period

Abstract

The invention relates to the field of feed, in particular to a compound premix feed of 1% green laying hens in laying period. The compound premix feed of 1% green laying hens in laying period is formed by uniformly mixing micronutrient substances of trace elements, vitamins, synthetic amino acids and the like, feed additives and powdered grain feed as a carrier, and is characterized by comprising active dry yeast, lactic acid bacteria, bacillus and digestive ferment. In the compound premix feed of 1% green laying hens in laying period, active dry yeast, growing element for poultry containing lactic acid bacteria and bacillus can inhibit propagation of pathogen; in wet mixed feed, active dry yeast and the like can be propagated and fermented, and partial pathogen can be inhibited and killed; and the palatability and digestibility of the feed can be improved in a certain time range. Microzyme, lactic acid bacteria and bacillus enter an alimentary tract for quick propagation, and can inhibit the growth of pathogen such as colon bacillus, salmonella and the like, thereby reducing diseases caused by pathogen, generating the effect similar to antibiotics, eliminating the damage of antibiotics to enteric microorganisms, better balancing intestinal flora, improving the immunizing power of laying hens, and improving the health level of laying hens.

Description

technical field [0001] The invention relates to the field of feed, in particular to a formula of premixed feed. Background technique [0002] Pollution sources from livestock and poultry farming are increasingly threatening the environment on which human beings depend. Whether the feed formula design is reasonable and the quality of laying hens during the laying period directly affects whether laying hen farming will cause great harm to the environment, and also affects the production performance of laying hens and the quality of eggs. In today's aquaculture industry, nutritional regulation and the addition of environmentally friendly feed additives can effectively reduce the pollution of the aquaculture industry to the environment. For example, appropriate dietary protein levels can effectively reduce nitrogen excretion, and adding phytase can reduce the amount of inorganic phosphorus sources. , and then reduce fecal phosphorus excretion. Adding probiotics can not only imp...

Problems solved by technology

It has been found that although antibiotics added to feed can improve the disease resistance of animals and bring economic benefits to production enterprises, they also have obvious negative effects. Antibiotics can cause some bacterial flora to mutate into drug-resistant strains, resulting in resistance. Drug properties, leading to decreased immunity of livestock and poultry, causing endogenous infection and superinfection, resulting in increased residues of antibiotics in livestock and poultry products and the environment
