Laying hen compound feed and preparation method thereof

Abstract

The invention provides a compound feed for a laying hen in egg-laying period and a preparation of the compound. The compound feed comprises the following ingredients: 64-66 wt% of corn, 20-22 wt% of soybean meal, 2-4 wt% of wheat bran, 0.5-1 wt% of fish steak powder, 0.4-1 wt% of cottonseed meal, 0.1-0.15 wt% of phytase (5000), 7-10 wt% of clamshell powder, 1-2 wt% of mountain meal, 0.5-1 wt% of calcium hydrogen phosphate, 0.3-1 wt% of salt, 0.2-0.4 wt% of 65%-lysine, 0.1-0.2 wt% of solid methionine, 0.06-0.1 wt% of choline chloride, 0.3-0.5 wt% of vitamin C, 0.2-0.4 wt% of trace element premix, and 0.2-0.4 wt% of vitamin premix, and is prepared by the following steps: extracting raw materials, carrying out fine grinding to on the raw materials with 2.0 mm sieves, and mixing the feed for 200 s, with the grain size of corn of 5.4 mm. The compound feed has scientific allocated proportion and simple preparation, reduces the usage of antibiotics, reduces drug residue in the laying hen body, has positive influences effects on the laying hen, and is economical and practical.

Description

technical field [0001] The invention relates to a compound feed for laying hens and a preparation method thereof. Background technique [0002] In recent years, with the development of the laying hen breeding industry, the requirements for compound feed for laying hens are getting higher and higher. Not only are there higher requirements for the nutritional level of the feed itself and the structure of raw materials, but also the impact on the breeding environment is also being explored. among. The impact of high temperature in summer on the production efficiency of laying hens has become increasingly prominent and has become a new focus of the breeding industry. [0003] 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 me...
