Abstract

The invention discloses a green laying-hen feed formula capable of reducing dirty egg rate and a preparation method thereof. The feed comprises the following ingredients: corns, bean meal, wet-base fermented soybean meal, cotton meal, corn DDGS, lard, stone powder, calcium hydrogen phosphate, lysine, methionine, sodium chloride and a compound premixed material for the laying hens. The preparation method comprises the following steps: preparing the wet-base fermented soybean meal, pre-treating the raw materials, and mixing the pre-treated materials. On basis of selecting raw materials which are easy to digest and absorb as the raw materials of the laying-hen feed, the bean meal fermented with a mixture of yeast, lactobacillus and bacillaceae is also added, so that enough intake of active microorganisms which are beneficial to the intestinal health is ensured during the breeding processes of the laying hens; thus, the laying-hen feed is capable of improving health of the laying hens by regulating the microbial flora of the intestinal tract. Moreover, the laying-hen feed is capable of improving egg yields of the laying hens, improving qualities and colors of the egg shells, and reducing the dirty-egg incidence rates.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a green laying hen feed capable of reducing the rate of dirty eggs and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's demand for eggs is gradually increasing. Consumers no longer only consider the nutritional value when buying eggs, but also have higher and higher requirements for the appearance indicators of eggs, such as glossiness and cleanliness. At present, there is a common phenomenon in laying hen farming in my country: raising high-egg-producing breeds, high-intensity breeding, poor breeding environment, weak management level, and using ordinary feed, etc., which easily lead to sub-healthy state of laying hens. Cotton, rapeseed meal and grain feed processing by-products are widely used in laying hen feed. In addition to a large amount of non-starch polysaccharides, these feed materials also contain c...
