Abstract
The invention discloses a preparation method of a feed for improving the digestive tract function of poultry, which comprises the following steps: crushing and sieving the waste grass roots, ball-milling the waste grass roots by vacuum liquid nitrogen until the waste grass roots pass through a 100-mesh sieve, and obtaining pretreated grass roots, wherein the vacuum degree is 30-50 kpa; regulating the temperature of pretreated grass root to 30-40deg.C, and adding 1-5×10 active bacteria 9 Fermenting cfu/g of composite bacteria for 2-5h, adding silage bamboo shoot shell, soybean meal, rice bran, peanut cake and calcium chloride water solution, and mixingUniformly carrying out hydrothermal reaction for 20-40min at 105-115 ℃, cooling to room temperature, and grinding to obtain superfine crushed grass roots; mixing superfine pulverized radix Glehniae, semen Maydis, testa Tritici, vegetable cake, semen Tritici Aestivi, shell powder and radix Puerariae powder, homogenizing under 30-50MPa to obtain premix; adding taurine, grape seed procyanidine, calcium bicarbonate and salt into the premix, stirring uniformly, granulating and obtaining the feed for improving the digestive tract function of poultry.
Description
Technical Field
The invention relates to the technical field of poultry feeds, in particular to a feed for improving the digestive tract function of poultry and a preparation method thereof.
Background
The key problems in the development of the farming industry are the health level and productivity of the animals. How to accelerate the growth of poultry and reduce the disease rate is a long-term concern in the field of poultry farming. With the rapid development of modern poultry farming industry in China, the problems of shortage of conventional feed resources, rising of feed raw material prices and the like are increasingly remarkable, and the development of non-grain feed is an important way for relieving the shortage of feed resources, reducing the raising cost and improving the economic benefit.
The lignocellulose biomass is the renewable biomass resource which is most abundant in the earth, and the lignocellulose biomass is used for preparing the feed, so that the high-value utilization of the waste biomass can be realized, and the problems of high price and dependence on import of the feed can be solved. The main components in lignocellulose are crude fibers such as cellulose, hemicellulose, lignin and the like; the food entering the digestive tract is decomposed into glucose and amino acid under the action of various digestive juice, so that after the food is digested and absorbed, the residue is discharged out of the body, but the digestive tract of the poultry is short and has small volume, so that the feed passes through the digestive tract at a higher speed, and the digestive absorption of nutrient substances is incomplete, so that the digestive tract diseases with different degrees are easily induced for a long time.
At present, in the intensive cultivation process of modern poultry, a method of adding feed antibiotics is adopted to prevent diseases, but the use of the antibiotics causes a plurality of problems, such as drug residues, drug resistance, body immunity reduction and the like, and the application of the antibiotics is greatly limited.

| Control group | 45.55 | 4.46 | 6.89 | 6.64 |
From the above table, it can be seen that: the feed provided by the invention reduces the death rate and improves the weight and slaughtering performance of broilers; the feed provided by the invention has the advantages that the proportion of balancing myostomach and adenosis is always maintained at 4.38-4.97:1, the growth and development of digestive organs of the broiler chickens can be promoted, the digestive tract regulation and repair of the broiler chickens can be realized, and meanwhile, the quality of muscles (particularly pectoral muscle and leg muscles) can be improved.
Then, 20 of the groups of example 5 and the control group were randomly selected, and the myostomach and the adenostomachs were dissected and tissue-sectioned, and the results thereof are shown in fig. 1 to 4, and it was found that: example 5 group of seeds have normal papilla and stomach wall and moderate hand feeling; in the control group, the glandular stomach nipple was found to be flat even disappeared, the hand feel was hard, the glandular stomach wall was thickened, the glandular mucosa was swollen and thickened, and 2 cases of ulcerated ulcer foci were appeared, and three-degree infection was caused.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
