Problems solved by technology

But at present, the probiotics used for premixes on the market have the main quality problems in the following aspects: (1) the type of strain is single; (2) the content of viable bacteria is low; (3) the moisture content is high, which affects One of the important factors of the quality of probiotics; (4) intolerance to antibiotics; (5) unstable to gastric acid and bile salts, etc.
[0004] Enterococcus faecium (Enterococcus faecium) and Bacillus licheniformis (Bacillus licheniformis) are one of the strains approved by the Ministry of Agriculture for microbial feed additives. Therefore, Saccharomycopsis fibuligera is used as a feed additive and added to laying hen premixes, and there are no research and application reports yet.

Abstract

Belonging to the premix field, the invention relates to an additive premix for laying hens. The premix of the invention mainly contains: soybean meal, calcium hydrogen phosphate, stone powder, salt, compound vitamin, nicotinic acid, D-calcium pantothenate, biotin, choline chloride, copper sulfate, ferrous sulfate, zinc sulfate, manganese sulfate, potassium iodide premix, sodium selenite premix, ethoxy quinoline, phytase, microecologics, xylo oligosaccharide, bentonite and rice husk. With xylo oligosaccharide and a plurality of probiotics and without antibiotic, the premix in the invention hasa reasonable formula and high viable bacteria content. Animal feeding experiments prove that the additive premix in the invention has ideal feeding effects. The ammonia concentration, the death and culling rate, and the broken egg rate can be reduced, while the laying rate and egg weight are enhanced. The composite premix provided in the invention can well promote the laying performance and health status of laying hens, and meet the needs of mass raising households, and is suitable for green and healthy culture so as to produce pollution-free egg products.

Description

technical field [0001] The invention relates to an additive premix for laying hens, belonging to the field of premix. Background technique [0002] The chicken industry is one of the pillar industries of my country's rural areas and agriculture. Due to the high density of chickens in chicken farms, poor ventilation and light conditions, feces are foul-smelling, and air pollution is serious, resulting in indigestion and loss of appetite in chickens, and various diseases are easy to spread. This not only affects the feed utilization rate and egg production rate, but also greatly increases the cost of medicine, which seriously affects the development of the chicken industry. According to statistics, the feeding period of a laying hen is 400-500 days, and the drug fee is 3-4 yuan. A large amount of medication in a short period of time also causes the amount of residual drug in chickens and eggs to seriously exceed the standard, endangering human health and seriously affecting ...
