Problems solved by technology

[0004] Aiming at the problem of low egg production rate of free range chickens existing in the prior art, the purpose of the present invention is to provide a feed that improves the egg production rate of free range laying hens. The egg production rate of chickens, while providing suitable nutrition for free-ranging chickens, has formulated a set of feed formula for free-range laying hens, which provides sufficient energy for free-range laying hens to meet their growth, exercise and heat preservation activities, and at the same time provide suitable protein, Amino acid and calcium energy nutrients can meet the laying needs of free-range laying hens while reducing feed waste

Embodiment Construction

[0008] A farmer in Changping District, Beijing, carried out 5 use tests, and selected two groups of free-range chickens for comparison, one group of free-range chickens were fed the feed of the present invention, and another group of free-range chickens were fed full-price feed on the market. The specific implementation of the present invention will be described in detail below through these 5 use tests.

[0009] In the first test, every kilogram of the feed that improves the egg production rate of the chickens in the range of the present invention includes full-price feed and supplementary feed, and the full-price feed includes corn, 720g; soybean meal, 175g; stone powder, 70g; salt, 2g; carbonic acid Calcium Hydrogen, 20g; Lysine, 1.4g; Methionine, 1.4g; Phytase 0.2g. The supplement provides Vitamin A, 8000IU; Vitamin D, 1600IU; Vitamin E, 150IU; Vitamin K, 0.5mg; Vitamin B1, 120mg; Riboflavin, 400mg; Vitamin B6, 200mg; Vitamin C, 250mg; Vitamin B12, 0.04mg ; Folic Acid, 0....

Abstract

The invention discloses feed for improving the laying rate of free range laying hens. The feed improves the laying rate of the free range laying hens by adding supplementary feed into complete feed; meanwhile, a feed formula for the free range laying hens is formulated to provide appropriate nutrients for the free range laying hens; the feed supplies sufficient energy for the free range laying hens to meet the requirements of activities of growth, exercise, heat insulation and the like of the free range laying hens, and simultaneously supplies appropriate nutrients such as protein, amino acid and calcium energy to reduce the waste of feed while meeting the requirement of the free range laying hens for egg laying.

Description

technical field [0001] The invention relates to the field of chicken feed ratio, in particular to a feed used to improve the egg production rate of laying hens. Background technique [0002] At present, in the feeding process of laying hens, there are mainly two situations. One is to only feed corn, and through free contact with the soil and surrounding vegetation environment, the laying hens can independently forage various insects, soft stems and leaves or seeds of vegetation. However, feeding only corn will lead to the lack of essential vitamins, mineral elements, amino acids and other nutrients in the laying hens, so the chickens are prone to nutritional deficiencies, such as pecking, poor feather growth, etc., and the egg production level is relatively low due to nutritional deficiencies. Low. The second is to feed full-price feed for caged laying hens. Due to the lack of exercise and high egg production rate different from large-scale cage chickens, free-range chick...
