Broiler chicken preliminary compound feed and preparation method thereof

Abstract

The invention discloses broiler chicken preliminary compound feed and a preparation method thereof. The compound feed comprises the following raw materials: broiler compound premix, salt, threonine, Maxus premix, stone dust, calcium hydrophosphate, lysine of 65 percent, liquid phytase, poultry mineral premix, solid methionine, rape-seed cake, rice bran oil, corn protein powder of 60 percent, bean dreg of 46 percent, choline chloride, corn, wheat and liquid wheat enzyme. The preparation method comprises the following steps that: raw materials are weighed according to the weight percentage to be put into a pulverizer; the pulverized mixture is granulated under the temperature of 75 DEG C to 80 DEG C, and a degree of gelatinization reaches more than 90 precent; and the produced particles are put into a crusher to be broken, and the breaking granularity is 8 meshes to 15 meshes. The broiler chicken preliminary compound feed has beneficial effects that: the preliminary nutrition demand of broiler chicken can be satisfied, antinutritional factors in wheat daily ration can be adequately decomposed, nutrient absorption can be increased, the conversion rate of the feed can be improved, the survival rate of pups and young poultry can be improved, and the production performance of the broiler chicken can be improved.

Description

technical field [0001] The invention relates to a compound feed for early feeding of broiler chickens, in particular to a compound feed for broiler chickens in the early stage and a preparation method thereof. Background technique [0002] For a long time, corn has been used as the main source of energy in poultry feed due to its high energy value and relatively low price. received more and more attention. Wheat resource has become the first choice to replace corn because of its wide planting area and high yield. However, wheat raw materials contain non-starch polysaccharides (NSP) such as arabinoxylan and β-glucan, and anti-nutritional factors such as crude fiber, trypsin inhibitors, plant lectins, and some special structural proteins that are difficult to be digested. Direct large-scale feeding not only wraps nutrients, hinders the interaction between nutrients and digestive enzymes, but also causes functional damage to livestock and poultry, which ultimately manifests a...

AI Technical Summary

Problems solved by technology

[0003] Wheat is used as a grain feed for poultry. Compared with corn, its nutritional value is higher in crude protein, calcium, and phosphorus, but its metabolizable energy and feed utilization rate are lower. Poultry fed wheat diets show poor growth and excrete sticky manure. Pollution of the environment, etc., the main reason is that wheat contains a high level of anti-nutritional factor arabinoxylan, which increases the viscosity of the intestine after absorbing water in the intestine, enhances the peristalsis of the intestinal wall, and compensatory hyperplasia of the digestive organs
