Compound feed containing fermented cottonseed meal for chicken for eggs and preparation method thereof

Abstract

The invention discloses a compound feed containing fermented cottonseed meal for chicken for eggs, and a preparation method of the compound feed. The compound feed comprises the following raw materials: corn, 46% of bean pulp, bran, fermented cottonseed meal, cotton kernel protein, peanut cake, mountain flour, calcium hydrophosphate, salt and gunk for chicken for eggs. The preparation method comprises the following steps of: weighing all of the raw materials according to percentage by weight; feeding the raw materials into a crusher to be crushed, wherein the crushing granularity is 20-30 meshes; feeding the materials into a pelletizer, wherein the pelletizing temperature is 75-80 DEG C, and the gelatinization degree is greater than or equal to 90%; and finely crushing, wherein the crushing granularity is 8-15 meshes. The compound feed has the beneficial effects that fermented cottonseed meal is adopted to take the place of a part of cottonseed meal, so that not only is the requirement of chicken for eggs on nutrition met, but also the production capacity of the chicken for eggs is improved; and in addition, due to the addition of Chinese medicine additives, the compound feed has both the medicine property and the nutrition, so that when the compound feed is used together with the main feed, the production capacity of the chicken for eggs is improved, and the immune function of the chicken for eggs is improved.

Description

technical field [0001] The invention relates to an animal breeding feed containing raw materials derived from plants, animals or minerals, in particular to a layer hen compound feed containing fermented cotton meal and a preparation method thereof. Background technique [0002] After decades of rapid development, my country's laying hen farming has leapt to the first place in the world. At present, there are more than 1.5 billion laying hens in my country. In the production of laying hens in China, more than 70% of laying hens come from small-scale chicken farms (less than 10,000) and free-range farmers. The problem of short cycle and low breeding profit, and due to the pressure of the dual risks of the market and epidemic diseases, the profit of laying hen farming is getting lower and lower. More than 75%, how to improve the quality of feed and increase income has become the key to laying hen farming. [0003] my country is a major cotton-producing country in the world, wit...

In the production of laying hens in China, more than 70% of laying hens come from small-scale chicken farms (less than 10,000) and free-range farmers.

More than 75%, how to improve feed quality and increase income has become the key to laying hen farming

Although cottonseed meal is rich in protein, it is a good source of animal protein feed, but because it contains free gossypol, which is toxic to animals, its use as feed is greatly restricted
