Growing-period feed capable of promoting development of digestive organs of laying hens and preparation method of growing-period feed

Abstract

The invention belongs to the technical field of feed compositions and relates to growing-period feed capable of promoting the development of digestive organs of laying hens and a preparation method. The growing-period feed is mainly prepared from the following raw materials in parts by weight: 45 to 60 parts of cereal, 8 to 15 parts of soybean meal, 1 to 8 parts of miscellaneous meal, 6 to 15 parts of bran, 3 to 8 parts of pomace, 2 parts of evening primrose meal, 0.8 to 1.5 parts of mountain flour, 0.8 to 1.5 parts of calcium hydrogen phosphate, 0.35 to 0.43 part of amino acid, 0.5 to 15 parts of vegetable oil, 1 part of compound premix, 0.05 to 0.2 part of prebiotics, 0.01 to 0.05 part of zinc methionine, 0.05 to 0.2 part of hydrolyzed tannic acid, 0.05 to 0.08 part of a compound enzyme preparation, 0.02 to 0.1 part of a mycotoxin adsorbent, 0.04 to 0.2 part of a mycotoxin degradation enzyme, 0.1 to 0.5 part of yeast hydrolysate and 1 to 5 parts of dietary fiber. By adopting the growing-period feed, indexes of all the digestive organs at a growing period of the laying hens are improved to different degrees.

Description

technical field [0001] The invention belongs to the technical field of feed compositions, and in particular relates to a rearing feed for promoting the development of digestive organs of laying hens, and to a preparation method of the feed. Background technique [0002] The feed for laying hens is the feed used by laying hens from the age of 7 weeks to 15 weeks. At this stage, the physiological functions are immature, and the bones, muscles and digestive organs are in a vigorous development stage. During this period, no eggs are produced. Farmers If you don't pay attention to it, the chicken feed used for breeding chickens has less corn and soybean meal, but more corn bran, corn DDGS, palm meal, cottonseed meal and other miscellaneous meals, resulting in serious excess of aflatoxin and destroying the normal balance of intestinal flora. The quality of miscellaneous meal fibers such as palm meal and corn by-products is not good, which has certain damage to the intestinal villi...

Problems solved by technology

The research of Xie Chunyan et al. showed that the soluble dietary fiber obtained by fermenting wheat bran with tea tree mushroom has a proliferative effect on the growth of lactic acid bacteria, but it has an inhibitory effect on the growth of Escherichia coli
