Abstract

The invention relates to the technical field of feed, and provides a laying hen feed and a preparation method thereof, wherein the laying hen feed comprises the following components in parts by weight: 15-18 parts of soybean, 15-20 parts of soybean meal, 10-16 parts of grease, 8-9 parts of bran, 10-14 parts of wheat bran, 5-8 of fish meal, 3-5 parts of erythrophyll, 2-4 parts of a protein powder, 10-15 parts of alfalfa, 4-6 parts of a premix, and 3-8 parts of a shell powder. The laying hen feed can improve the disease resistant ability of laying hens, reduce the rectocele rate and increase the layering rate, and especially can reduce cholesterols in eggs, deepen egg yolk color, improve egg yolk condition and improve contents of egg selenium, folic acid, unsaturated fatty acids and other nutrients; the feed proportion is simple, the preparation method is easy, and the cost of the feed is reduced.

Description

technical field [0001] The invention relates to the field of chicken feed, in particular to a layer chicken feed and a preparation method thereof. Background technique [0002] Corn has low wholesale prices and is widely used in traditional feed formulations. The weight of eggs laid by traditional feed-fed layer hens is about 50-60g, the cholesterol content is as high as 584mg / 100g, and corn is prone to produce Aspergillus flavus. The Chinese Nutrition Society recommends that the amount of cholesterol consumed per person per day is 300 mg, and two eggs per person per day will be detrimental to health. The high cholesterol content prevents people with high blood lipids and middle-aged and elderly people from eating more eggs every day. Reduce egg cholesterol content by improving feed, generally can only reduce about 20-30%, egg cholesterol content still reaches 408-467mg / 100g, still can't completely solve the problem of high cholesterol content, the laying hen that reduces ...
