Problems solved by technology

The main components of lignocellulose are crude fibers such as cellulose, hemicellulose, and lignin; the food that enters the digestive tract is decomposed into glucose and amino acids under the action of various digestive juices, and after the food is digested and absorbed, the residue forms feces It is excreted from the body, but the digestive tract of poultry not only does not have the enzyme to digest crude fiber, but also has a short digestive tract and a small digestive tract volume, so the feed passes through the digestive tract at a faster speed, and the digestion and absorption of nutrients is not complete. If things go on like this, it is easy to induce different degree of gastrointestinal disease
[0004] At present, in the process of modern poultry intensive farming, although the method of adding feed antibiotics is used to prevent such diseases in production, the use of antibiotics has caused many problems, such as drug residues, drug resistance, and reduced body immunity. Its application has been greatly limited

Abstract

The invention discloses a preparation method of feed for improving digestive tract function of poultry. The preparation method comprises the following steps: crushing and sieving waste Chinese wildrye roots, ball milling with vacuum liquid nitrogen to pass a 100-mesh sieve with a vacuum degree of 30-50 kpa to obtain pretreated Chinese wildrye roots; adjusting a temperature of the pretreated Chinese wildrye roots to 30-40 DEG C, adding compound bacteria with a total number of effective viable bacteria being 1-5 * 10 < 9 > cfu / g for fermentation for 2-5 hours, then adding silage bamboo shoot shells, soybean meal, rice bran, peanut cakes and a calcium chloride aqueous solution, uniformly mixing, performing hydrothermal reaction at 105-115 DEG C for 20-40 minutes, cooling to room temperature, and grinding to obtain superfine ground Chinese wildrye roots; uniformly mixing the superfine ground Chinese wildrye roots, corn, bran, rapeseed meal, wheat, shell powder and radix puerariae powder, and homogenizing at 30-50 MPa to obtain a premix; and adding taurine, grape seed procyanidine, calcium bicarbonate and salt into the premix, uniformly stirring, and granulating to obtain the feed for improving digestive tract function of poultry.

Description

technical field [0001] The invention relates to the technical field of poultry feed, in particular to a feed for improving the function of poultry digestive tract and a preparation method thereof. Background technique [0002] The key issue in the development of the breeding industry is the health level and production capacity of animals. How to accelerate the growth of poultry and reduce the disease rate is a long-term focus in the field of poultry breeding. With the rapid development of my country's modern poultry breeding industry, the shortage of conventional feed resources and the rising price of feed raw materials have become increasingly prominent. The development of non-grain feed is an important way to alleviate the shortage of feed resources, reduce feeding costs, and improve economic benefits. [0003] Lignocellulosic biomass is the most abundant renewable biomass resource on the earth. Using lignocellulosic biomass in the preparation of feed can not only realize...
