Feed for improving disease resistance of laying hens, and preparation method and application thereof

Abstract

The invention relates to the field of feed, in particular to a feed for improving the disease resistance of laying hens, and a preparation method and application thereof. The feed is prepared from thefollowing raw materials in percentage by weight: 30% to 50% of corn, 10% to 25% of soybean meal, 5% to 20% of rubber seed cakes, 2% to 2.5% of fly pupae powder, 5 % to 20% of soybean hulls, 0.5% to 1% of soybean oil, 0.2% to 0.4% of salt, 0.10% to 0.18% of methionine, 0.1% to 0.3% of lysine, 0.5% to 1.2% of calcium hydrogen phosphate, 6% to 9% of stone powder, 2% to 3% of sanguinarine, and 1% to2% of a premix. The feed disclosed by the invention has a larger gap with feed of the same stage in the market in the aspects of the types and components of main raw materials, and provides a new formula for feed of laying hens. The preparation method is simple, and the feed has the advantages of high stability, good condition controllability, low price and a good application prospect.

Description

technical field [0001] The invention relates to the field of feed, in particular to a feed for improving disease resistance of laying hens and a preparation method and application of the feed. Background technique [0002] For the entire life cycle of laying hens, the laying period is undoubtedly the most concerned period, which has a decisive impact on the breeding efficiency. Over the years, grass-roots farming customers have been concerned about the single feed structure, uneven quality of raw materials, rough feeding methods, and irregular medication during the laying period of laying hens, which made the development of breed advantages slow or incomplete or even reduced, resulting in a decline in production efficiency . In addition, the temperature in summer is high, and the microbial reproduction is active, which is easy to cause various digestive tract diseases of laying hens. Therefore, the high temperature in the summer environment will have a great impact on the ...

Problems solved by technology

In addition, in recent years, with the rapid development of the aquaculture industry, the prices of corn, soybean meal, and imported fish meal as the main raw materials for feed have continued to rise, the production cost of laying hens has increased day by day, and there are various opportunistic pathogenic bacteria (Salmonella lactis) in fish meal , Escherichia coli, etc.), some fish meal also contains gizzard erosin, which increases the positive rate of pullorum and affects brooding and egg production performance
