Feed for broiler chickens having high dressing percentage and low abdominal fat percentage and preparation method of feed

Abstract

The invention relates to the technical field of a feed for poultry, and particularly discloses a feed for broiler chickens having a high dressing percentage and a low abdominal fat percentage and a preparation method of the feed. According to the feed for the broiler chickens and the preparation method of the broiler chickens, disclosed by the invention, soybean phospholipid powder and lipase are added in the feed, and a certain proportion of soybean oil is used for replacing fish oil to be used in the chicken feed, so that the slaughter performance of the broiler chickens can be improved, the effect of the abdominal fat percentage is reduced, and the growing performance of the broiler chickens is improved. The feed has the advantages of high safety, high economy, high efficiency and the like. The feed disclosed by the invention does not have the problems that any residues exist and pollution exists, has higher economic benefits and is suitable for breeding plants for supplying slaughtered broiler chickens.

Description

technical field [0001] The invention relates to the technical field of poultry feed, in particular to a broiler feed with high slaughter rate and low abdominal fat rate and a preparation method thereof. Background technique [0002] Due to the rapid growth rate of broilers, a certain proportion of fat is often added to the diet to ensure a higher energy value requirement. Compared with other energy raw materials such as corn, wheat, sorghum, etc., oil has the lowest cost per unit of energy value, so it is widely used in livestock feed. After the fat enters the digestive tract of the animal body, it needs to be gradually utilized by the body after emulsification and enzymatic hydrolysis. The emulsification of fat mainly relies on the secretion of bile by the liver, and the intestinal secretion of lipase to hydrolyze triglycerides. The utilization of fat may be limited due to insufficient secretion of animal bile or endogenous lipase. In addition, differences in oil sources ...

Problems solved by technology

[0004] Zhao Yumei's patent "Feed for Improving the Quality of Broiler Ketones" (Application No.: 201310478598.0) invented a traditional Chinese medicine composition feed additive used to improve the quality and flavor of yellow feather broilers' ketones, and does not involve improving slaughter rate and abdomen. Fat rate; Fu Panpan's patent "a chicken feed and feed additive that can reduce broiler blood fat and promote broiler performance" (application number: 201310120162.4) uses 1-10% biochar feed additives to promote broiler performance , reduce abdominal fat rate and feed-to-meat ratio. The preparation of this biochar feed additive needs to go through oxygen-limited and low-temperature processes. The preparation conditions are not easy to control, and the production process is cumbersome. A Compound Feed Additive for Reducing Body Fat Deposition in Broilers" (Application No.: 201410099814.5) requires the use of trimethylamine, plant polyphenols, berberine, and cassia seeds, among which berberine and cassia seeds are Chinese herbal medicines and are not easy to obtain, while trimethylamine Amines are chemical raw materials that are harmful to human health and are flammable and explosive
