Abstract
The invention discloses a corn by-product fermented feed for laying hens and a preparation method thereof, according to the low price and the nutritional characteristics of the corn by-product, the water content of the fermented corn by-product is controlled to be 15-20% by microbial fermentation with steam as a heat source, organic acid, small peptide and bioactive substances are improved after the corn by-product is subjected to microbial fermentation, mycotoxin is further reduced, the laying rate is improved by 4.6-10.7% on the basis of reducing the feed cost, the technical problems of low utilization rate of the nutrient substances, safe quality and the like in the application process of the corn by-product are solved, and a data support is provided for replacing bean pulp to reduce the breeding cost of the laying hens.
Description
Technical Field
The invention relates to the technical field of feeds, in particular to a corn byproduct fermented feed for laying hens, and preparation and application thereof.
Background
Corn is one of three main grain crops in the world and is also one of three main grain varieties in China, the corn yield in China accounts for about 35% of the total grain yield in China, the corn in China is mainly used for producing feed for a long time, but the consumption structure of the corn is changed along with the change of social requirements and the continuous development and progress of the corn deep processing industry. The development of the corn deep processing industry becomes a way for utilizing the corn.
The yield of the Xinjiang corn is 600 million tons, wherein corn deep processing enterprises consume 300 million tons of corn, corn byproducts are produced 150 million tons every year, and the corn processing byproducts refer to other products except main products in the industrial processing process of the corn. The corn processing by-products mainly comprise corn protein powder, corn bran (guniting/non-guniting), corn germ cake/meal, DDGS and the like, the yield of the corn processing by-products is about 30% of the corn processing amount, and the corn processing by-products can be used as high-quality feed resources. However, the corn queen-added by-products have certain defects in the aspect of nutrient content, even contain trace toxin and heavy metal components when the nutrient components are unbalanced, and are directly discarded to cause harm to the environment, so that certain risks still exist when the corn queen-added by-products are fed to animals. At present, the research on the corn processing byproduct fermented feed mainly focuses on the application of animal feed.
The high-protein feed is an important input product in the breeding industry and is a basis for ensuring the egg yield of laying hens, the main component in daily ration of the laying hens is bean pulp, the bean pulp contains rich protein, and the bean pulp is derived from grains, so the bean pulp is also a main protein source in the feed of the laying hens, and along with the rapid development of the chicken raising industry, the bean pulp on the market is not in demand at present, so some researchers aim to utilize other edible substances rich in protein to replace or reduce the using amount of the bean pulp, thereby reducing the cost and bringing huge economic effect, and relieving the problems of increasing the feed of people and livestock to a certain extent and the like.
