Abstract

The invention discloses a low-protein daily ration, and relates to the field of feeds. The low-protein daily ration is prepared from the following components in percentage by mass: 90-95% of corn, 2-6% of soybean meal, 0.2-1.6% of soybean oil, 0.3-0.4% of sodium chloride, 0-1.1% of calcium hydrophosphate, 0.65-1% of stone powder, 0.4-0.64% of lysine, 0.02-0.07% of methionine, 0.16-0.23% of threonine, 0.04-0.1% of tryptophan, 0-0.12% of isoleucine and 0.8-1.2% of a premix; and the premix comprises a vitamin premix and a trace element premix. The low-protein daily ration prepared by the formulacan reduce the influence of the emission of nitrogen in breeding excrement on the environment, ensure that the fattening pigs have better production performance, improve the daily gain of fat-free lean meat of the fattening pigs, reduce the muscle fiber density of the fattening pigs, reduce the content of cholesterol and malondialdehyde in plasma of the fattening pigs and improve the species diversity index of intestinal content microorganisms of the fattening pigs.

Description

technical field

[0001] The invention relates to the field of feed, in particular to a low-protein diet. Background technique

[0002] For a long time, my country has been facing a shortage of protein feed resources, and nitrogen emissions from farming excreta have brought about a greater environmental impact. The aquaculture industry has been squeezed by both cost and environmental protection, forcing the application of new cost-saving and efficiency-enhancing technologies. Since the 1990s, low-protein diets have become a research hotspot in the world of animal nutrition. my country has also followed up the research on core theories and technologies such as ideal amino acid balance. At present, the preparation and application technology of low-protein diets has matured, especially The establishment of basic theories such as animal nutrition net energy system and ideal amino acid model, and the industrialization of amino acids have greatly reduced costs, making it possible to ...
