Abstract

The invention discloses a feed capable of improving the growth performance of broiler chicken as well as a preparation method and an application of the feed. The feed comprises the following components in percentage by weight: 0.05-0.15% of N-carbamylglutamic acid, micronutrients and an energy feed. The preparation method of the feed comprises the following steps: (1) removing impurities of the micronutrients and the energy feed in percentage by weight, airing and then crushing the micronutrients and the energy feed into 40-100 meshes; and (2) mixing and stirring the micronutrients and the energy feed crushed by the step (1) with N-carbamylglutamic acid in percentage by weight, and sieving to obtain a feed finished product. By virtue of the N-carbamylglutamic acid-containing feed produced by the method is capable of facilitating to endogenous angiogenesis of broiler chicken and synthesis of protein, improving the daily gain of the broiler chicken, reducing the ratio of feed to weight and further improving the growth performance of the broiler chicken.

Description

technical field [0001] The invention relates to feed for animals, in particular to a feed containing N-carbamylglutamic acid that can improve the growth performance of broilers, a preparation method and application thereof. Background technique [0002] Arginine is a basic amino acid with six carbon atoms. It has a variety of important physiological and biochemical functions. It can not only be used as an important raw material for protein synthesis in animal cells, but also for the synthesis of important biologically active substances such as nitric oxide, polyamine and creatine in the body. precursor. [0003] Arginine is an essential amino acid for young mammals. For poultry, because there is no carbamoyl phosphate synthase in the mitochondria, arginine cannot be synthesized endogenously through the urea cycle, which determines the arginine content of broilers. Acid requirements are higher than those of other species and are currently entirely provided by the diet. Howe...
