Low-protein antibiotic-free ration for weaned pigs and application of low-protein antibiotic-free ration

Abstract

The invention relates to a low-protein antibiotic-free ration. The low-protein antibiotic-free ration comprises L-lysine hydrochloride, DL-methionine, L-threonine, L-tryptophan and branched chain amino acids. Under the condition of being free from antibiotic growth promoting agents, the low-protein ration is prepared, through adjustment of proportion and quantity of the lysine, the methionine, thethreonine, the tryptophan, three branched chain amino acids and the like, so that the diarrhea rate of the weaned pigs after weaning can be reduced; the metabolic capability of the weaned pigs for protein and the deposit capacity of the weaned pigs for nitrogen are improved; the digestive absorption level of amino acids by the weaned pigs is increased; the development of intestines of the weanedpigs is promoted; the digestive ability of the weaned pigs for lactose, cane sugar and maltose is improved; the digestive ability of the weaned pigs for protein, energy, and dry matter is improved; and the absorptive capacity of the weaned pigs for nutrient substances is improved.

Description

technical field [0001] The invention relates to the field of animal husbandry feed, in particular to a low-protein and antibiotic-free diet for weaned piglets and an application thereof. Background technique [0002] As a growth promoter, antibiotics can improve the growth performance of animals, and are widely used as additives for livestock and poultry feed, which greatly improves the production level of livestock and poultry. However, the random addition and excessive use of antibiotics have caused serious problems in the field of livestock and poultry production. serious consequence. The Ministry of Agriculture recently released the "National Action Plan for Containing Antimicrobial Resistance of Bacteria of Animal Origin (2017-2020)". The use of antibiotic growth promoters in China will become increasingly limited and may even be banned in the future. [0003] After research, we found that when antibiotic growth promoters (AGPs) were removed from the diets of weaned p...
