Fermentation type compound feed for laying hens

Abstract

The invention relates to a fermentation type compound feed for laying hens. The problems that nutrient resistant components are high, and the discharge quantity of nitrogen elements and ammonia in a poultry house is large, are fundamentally solved. The fermentation type compound feed is characterized by comprising the following components in parts by weight of 564-601 parts of corn, 12.6-31 partsof corn protein powder, 20-45 parts of corn DDGS, 11-28 parts of corn germ meal, 20-35 parts of cottonseed meal, 114-172 parts of soybean meal, 40-80 parts of fermentation raw materials, 74-85 parts of stone powder, 5-7 parts of soybean oil, 6-8 parts of dicalcium phosphate, 2.5-3.0 parts of sodium chloride, 0.4-0.6 part of choline chloride, 1-1.5 parts of methionine, 2.3-5 parts of lysine salt, 0.2-0.3 part of phytase, 10-12 parts of a trace element premix feed, 1-1.1 parts of a vitamin premix feed and 0.2-0.3 part of complex enzymes, wherein the enzyme activity of the phytase is 5000U/g. Thefermentation type compound feed is reasonable to design, the laying rate is increased, the feed-egg ratio is reduced, the discharge quantity of nitrogen elements in excrement and urine is reduced, and the economic benefits of an enterprise are increased.

Description

technical field [0001] The invention relates to a feed for laying hens, in particular to a fermented compound feed for laying hens which is rationally prepared by adding fermented feed raw materials. Background technique [0002] The aquaculture industry in China has developed a huge scale, and the annual feed consumption in the country is very large, which can reach more than 350 million tons. Soybean meal is currently the most widely used vegetable protein feed material, but there are many anti-nutritional factors in soybean meal, such as trypsin inhibitors, antigenic proteins, oligosaccharides, etc., which will reduce the production performance and feed utilization rate of livestock and poultry. Antinutrients in feed not only affect the health of poultry, reduce feed digestion and utilization, and reduce economic benefits, but the undigested feed is excreted with feces, affecting soil, water, and air, and is also harmful to human health. At present, the crude protein raw...

Problems solved by technology

What is common on the market is a single raw material for fermentation, such as fermented soybean meal, fermented cotton meal, fermented rapeseed meal and other single raw materials. There is a lack of mixing two or more feed materials and then fermenting them simultaneously under certain conditions. The practice of adding raw materials into the formula as a raw material, and there is also a lack of research on the production performance of laying hens after adding fermented feed under specific energy protein conditions

[0003] In order to solve the above problems, the existing patent CN201710533433.7 discloses "a method for making biologically fermented feed for laying hens", and patent CN201710286449.2 discloses "a green fermented compound feed for laying hens and its preparation method", Although the feed has been fermented to improve feed utilization to a certain extent, the patent does not address the application of compound enzymes for laying hens, and the enzymatic hydrolysis of raw material substrates is limited, resulting in low utilization of corn by-products in the formula. Unabsorbed nitrogen pollutes the environment

[0004] As another example, the patent CN201710086088.7 discloses "the method of raising laying hens using microecological preparations", but only adding 0.05% to 0.09% as an additive, which is essentially different from the addition of 4% or more after fermentation of large raw materials. The feed formula applied after the fermentation of large raw materials still needs further research
