Compound feed for promoting development of muscular stomach of broiler and preparation method of compound feed

Abstract

The invention belongs to the fields of a feed composition and feed processing, particularly relates to a compound feed for promoting the development of the muscular stomach of a broiler, and further provides a preparation method of the feed. The content of crude fibers in percentage by mass of the compound feed is greater than or equal to 4%, and the compound feed is mainly prepared from the following raw materials in parts by weight: 45-60 parts of corn, 3-15 parts of whole wheat grains, 1-3 parts of tropina, 1-5 parts of cottonseed meal, 1-5 parts of oat hull, 0.8-2 parts of calcium hydrogen phosphate, 1-2.5 parts of amino acids, 0.05-0.3 part of sodium humate, 0.05-0.1 part of a mycotoxin adsorbent, 0.02-0.1 part of betaine, 0.1-0.5 part of choline chloride, 0.05-0.3 part of a compound enzyme preparation, 0.5 part of a compound premix, 3-6 parts of fat, and 0.5-5 parts of probiotics. The compound feed disclosed by the invention can notably increase the weight of fresh chicken's gizzards, compared with the weight of each fresh chicken's gizzards of a broiler fed with a common feed, the weight of each fresh chicken's gizzard of the broiler fed with the compound feed is increased by 2-5 grams, and compared with the weight of each fresh chicken's gizzards of a broiler fed with granular feeds, the weight of each fresh chicken's gizzard of the broiler fed with the compound feed is increased by 8-15 grams.

Description

technical field

[0001] The invention belongs to the field of feed composition and feed processing, and in particular relates to a compound feed for promoting the development of broiler gizzard and a preparation method of the feed. Background technique

[0002] Feed particle size affects the anatomical and physiological characteristics and functions of the digestive system, even intestinal microecology and pH, especially gizzard development. During the processing of pellets, the starch is gelatinized by high temperature treatment, which destroys and softens the cell wall of the fibrous structure, denatures the protein, stabilizes the fat and facilitates digestion and absorption. At the same time, antinutritional factor activity and toxins were inhibited. The source of feed raw materials is wide, the formula cost is low, broiler chickens eat pellets quickly, and they are not picky eaters, which saves maintenance needs. The ratio of feed to meat in the early stage of feeding i...
