Feedstuff for laying hens and use thereof in producing laying hens

Abstract

The invention discloses forage for laying hen and application thereof in laying hen production. The forage is prepared by following weight of components: 50-53 parts of corn, 12-18 parts of middle protein soybean meal, 4-6 parts of cotton meal, 4-6 parts of corn DDGS, 9-10 parts of stone powder, 0.8-1.2 parts of meat bone meal, 11-15 parts of biological protein forage and 0.8-1.2 parts of 1% laying hen premix. The biological protein forage provided by the present invention is light brown forage raw material with high quality, high energy and high protein, and has concentrated fragrance and strong palatability, so animal likes the forage. Content of thalline protein, peptide and free amino acid of the forage is high, and nutrient composition absorptivity is high. Simultaneously the raw material contains a large amount of beneficial microorganism and unknown growth factor, thereby improving micro-ecological environment in intestinal tract, increasing resistivity and disease resistance of animal, and reducing content of antibiotic medicament in the forage.

Description

technical field [0001] The invention relates to a feed for laying hens, in particular to a feed for laying hens which uses new energy raw materials instead of corn, and also relates to an application of the feed in the production of laying hens. Background technique [0002] In recent years, with the increase in industrial consumption, the price of corn has risen sharply, reaching a historical high in the past 10 years. As the main raw material for the breeding industry, the sharp rise in the cost of corn has driven the price of livestock and poultry products to rise all the way. According to the information released by the Ministry of Agriculture, From January to October this year, the price of corn remained above 1.65 yuan for 10 consecutive months, with an average price of 1.68 yuan. Compared with the same period last year, the price of corn rose by 20.3%. Rising, or 3.1% and 10.4%, 7.3%, 8.1% respectively. Recently, the stock of corn production areas has decreased, farm...

Problems solved by technology

[0006] Substitution of wheat raw materials for corn also has the following disadvantages: ① low crude fat content (1.70% in wheat, 3.60% in corn), lower energy and linoleic acid content than corn, linoleic acid in wheat is only 0.8%, and linoleic acid in corn There is 2.0% acid, there is no lutein in wheat, but rich in lutein (22mg / kg) in yellow corn, lutein can be deposited in fat, skin and egg yolk

In view of the limited conditions of the use of this type of raw material, there are many reports in the feed industry on the use of corn instead of corn in pig feed, but there are no reports on chicken feed.
