Problems solved by technology

However, the above-mentioned combination has the following problems: the content of anti-nutritional factors in protein raw materials is high, while the content of high-quality nitrogen source nutritional small peptides and free amino acids is low, which reduces the biological potency of protein and amino acids, and is not conducive to the conversion of feed protein to body protein. Transformation; undigested nitrogen source nutrients are excreted with feces, which not only wastes precious protein resources, but also causes "eutrophication" pollution of water and soil

Abstract

The invention discloses a low-protein feed for small broiler chicken and a preparation method thereof. The protein content of the feed is 17.0 to 18.0 percent and is 20 percent lower than that of a common feed for the small broiler chicken, and the feed is suitable for the small broiler chicken at the age of 15 to 35 days. Common bean pulp and mixed meal are prepared into enzymolysis bean pulp and enzymolysis mixed meal by enzymolysis, so that anti-nutritional factors are reduced, small molecular polypeptide content and soluble protein content are increased, and digestion and absorption of nitrogen-derived nutritional substances are facilitated. By reducing the protein content, the cost of the feed is reduced, and excrement discharge and pollution of livestock are reduced; and by enzymolysis, digestion and absorption of proteins for the small broiler chicken are improved, the growth performance, the feed-meat ratio and the chicken quality of the small broiler chicken are ensured, and economic benefits are improved.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a meat-in-meat chicken low-protein feed and a preparation method thereof. Background technique [0002] Broiler chickens have the characteristics of fast growth, short feeding cycle and high feed remuneration. Generally, the weight of broiler chicks is about 40g when they hatch. Due to the wide application of full-price feed, the weight of broiler chickens at the age of 0-3 weeks can reach about 0.6kg, and the weight of broiler chickens at the age of 4-6 weeks can reach about 2.3kg. The ratio is about 2.0:1. It can be seen that 3-5 week-old broiler chickens are in a period of vigorous growth and have high requirements for the supply of nutrients. The increase in body weight is mainly due to the deposition of body protein, so the level and quality of feed protein have a great influence on the growth rate of chickens and the quality of chicken meat. [0003] At present, soybean meal i...
