Description
Technical field
The present invention relates to animal feed, be specifically related to a kind of feed, the preparation method and its usage that can improve broiler growth performance containing N-carbamylglutamic acid.
Background technology
Arginine is the basic amino acid of six carbon atoms, has multiple important biochemical functions, can, as the important source material of zooblast synthetic protein, also be not only the precursor of the important biomolecule active material synthesis such as body intracellular nitric oxide, polyamines and creatine.
Arginine is mammiferous necessary amino acid in children's age, for poultry, because there is not carbamyl phosphate synthetase in its mitochondria, not by the endogenous synthesis arginine of urea cycle, this arginic requirement just determining Broiler chicks is higher than the animal of other kinds, will be provided by diet completely at present.But arginine is high and have antagonism with lysine, tryptophan and histidine and fail to use as feed addictive large-scale popularization in animal productiong by price.
N-carbamylglutamic acid is the analogue that in urea cycle, ornithine generates the intermediate N acetylglutamate of citrulling, it can activate first the enzyme CPS-I (being also a key enzyme in enterocyte synthesis arginine process) in urea cycle, promote urea cycle (arginine main circulation approach in vivo), thus improve the endogenous arginine synthesis of body.As the endogenous synthesis activator of arginine, N-carbamylglutamic acid price is only arginic 10%, therefore more and more by the concern of people.Existing N-carbamylglutamic acid is applied in pig feed, sow reproductive performance can be improved, but arginine cannot endogenously synthesize in poultry, and N-carbamylglutamic acid is applied in merely in poultry feed, is difficult to the synthesis promoting the endogenous generation of Broiler chicks arginine and protein.
Therefore, adding arginic defect, the synthesis promoting the endogenous generation of Broiler chicks arginine and protein containing N-carbamylglutamic acid Feed Energy that the present invention produces for overcoming external source in Broiler chicks raising, improving Broiler chicks daily gain, reduce feed-weight ratio, and then improve the growth performance of Broiler chicks.
