Application of N-carbamylglutamic acid contained fodder in promoting growth of pigs

Abstract

The invention discloses an application of N-carbamylglutamic acid contained fodder in promoting the growth of pigs, the steps are as follows: a. N-carbamylglutamic acid is pulverized and is sieved by 40 to 100 meshes; b. the N-carbamylglutamic acid powder obtained from step a is fully mixed with premix or complete feed; c. all the components obtained from the step b are added into a blender for being stirred for 6 to 15 minutes according to the proportion, and then the above components are made into granular (or powdery) form and are packaged into bags. The obtained N-carbamylglutamic acid contained fodder is used for feeding suckling piglets, weaning piglets or reserved sows and growing pigs. The N-carbamylglutamic acid contained fodder can promote the protein of the piglets to be synthesized, relieve the weaning stress of the piglets and improve the born number of the sow, therefore, the N-carbamylglutamic acid contained fodder has good application prospect.

Description

technical field [0001] The invention relates to the technical field of feed additives for promoting rapid growth of piglets, alleviating weaning stress, and promoting the growth and production performance of sows, and more specifically relates to a feed containing N-carbamylglutamic acid in promoting the growth and production of piglets and sows It is suitable for promoting the rapid growth of piglets, relieving weaning stress and promoting the growth and production performance of pigs in animal husbandry. Background technique [0002] Arginine is an essential amino acid during fetal and lactation periods in mammals (Wu et al., Arginine requirements of piglets, Journal of Nutrition, 2004). The amount of arginine in breast milk and the endogenous synthesis of suckling piglets can not meet the needs of their growth. The lack of arginine is a major factor limiting the growth of suckling piglets. The production of suckling piglets is very important to the whole pig production, ...

However, its absorption is antagonistic to lysine, and side effects such as diarrhea occur when excessive intake of exogenous arginine, and the price of arginine is expensive, and the price per ton is as high as more than 100,000 yuan. The cost of feed has been increased, so it is of great significance to find another way to increase the supply of endogenous arginine in pigs

[0003] Some data show that carbamoyl phosphate is necessary for the synthesis of citrulline from ornithine, while N-acetylglutamic acid is necessary for the synthesis of N-acetylglutamate synthase (NAGS) and 5-carboxy-pyrroline Metabolic allosteric activators of the enzyme (pyrroline-5-carboxylate synthase, P5CS) (Susumuk et al., Effects of in vitro addition of disulfide or thiol compounds on the activity of the arginine activator N-acetylglutamate synthase, Molecular Catalysis Substance B; Enzyme, 2000, 10; 191-197), but in the small intestinal mucosa and liver mitochondria of suckling piglets, the synthesis of N-acetylglutamic acid is insufficient due to the deficiency of acetylglutamate synthetase (Uchiama.C et al., Subcellular localization and characteristics of N-acetylglutamate synthetase in mouse small intestine mucosa, Biochemistry, 1981, 89; 1777-1786), therefore, N-acetylglutamate may play a role in regulating cucurbit synthesis in the small intestine of suckling piglets. amino acid and arginine play an important role in the process
