Abstract

An early-stage compound feed for broiler chickens comprises the following raw materials in parts by weight: corn 56-62, soybean meal 18-25, an enzymatically-decomposed and fermented rapeseed meal 3-9, bran 0-5, salt 0.3-0.4, lysine 0.4-0.5, methionine 0.2-0.5, grease 1-3, and a premix which does not contain a pharmaceutical additive 1-5, wherein the enzymatically-decomposed and fermented rapeseed meal is prepared by mixing rapeseed meal, a combination enzyme, plant lactobacillus solution, bacillus subtilis solution and water according to the proportion of the rapeseed meal, the combination enzyme, the plant lactobacillus solution, the bacillus subtilis solution and water being 75.5: 0.5: 1-3: 3-6: 15-20 by weight and allowing the raw materials to enzymatically decompose and ferment; the combination enzyme comprises neutral protease, pectinase, Beta-glucanase, xylanase, cellulose and mannanase. The preparation method of the early-stage compound feed comprises the following steps: uniformly mixing the above raw materials in the required proportions to obtain the mixture material, and subjecting the mixture material to pasting, palletizing and crushing in turn. The nutritional quality of the rapeseed meal is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a pre-broiler compound feed prepared with enzymatically hydrolyzed and fermented rapeseed meal and a preparation method thereof, which is suitable for increasing the ratio of rapeseed meal added to young animal rations and reducing production costs . Background technique [0002] Rapeseed meal is a by-product of oil processing with a huge output in my country. It is cheap, rich in protein and of good quality. , crude fiber and other anti-nutritional factors. The digestive organs and immune organs of young animals are immature, and they are sensitive to the toxic components and anti-nutritional factors in rapeseed meal, which seriously restricts the application of rapeseed meal in compound feed for young animals. [0003] Although the content of glucosinolate and erucic acid in the double-low rapeseed meal improved through genetic breeding in recent years has been reduced, due to the p...
