Daily ration for fattening cattle in winter

Abstract

The invention belongs to the technical field of animal nutriology, and relates to a daily ration for fattening cattle in winter. The daily ration is prepared from the following raw materials in percentage by weight: 20%-30% of the compound ammoniation-treated feed, 20%-30% of silage, 10%-15% of steam-flaked corn, 10%-15% of palm meal, 10%-15% of corn germ meal, 1%-10% of sunflower seed meal, 1%-5%of rice bran meal, 5%-10% of bran, 1%-5% of medical stones, 0.5%-1% of calcium powder, 0.5%-1% of table salt and 1% of a premix. The daily ration can fundamentally eliminate rumen acidosis of fattening cattle, significantly reduce the cost of the daily ration for fattening cattle, and significantly improve the daily weight gain, carcass weight, slaughtering rate, net meat rate, meat-bone ratio and meat-fat ratio of fattening cattle.

Description

technical field

[0001] The invention relates to a diet for fattening cattle, which belongs to the technical field of animal nutrition. Background technique

[0002] In beef cattle production, in order to improve the production performance and economic benefits of fattening cattle, high-starch and high-protein diets, that is, high-concentrate diets, are often fed to fattening cattle. Because the concentrate has the characteristics of high starch and low physically effective neutral detergent fiber (pe NDF), excessive intake of concentrate by fattening cattle will lead to the accumulation of volatile fatty acids (VFA) in the rumen, which will cause a decrease in rumen pH and increase the Risk of stomach acidosis. Under the condition of high concentrate, a large amount of VFA is produced and accumulated, the pH value of the rumen decreases, the metabolism of the rumen is disordered, and a large number of abnormal metabolites are produced, including lipopolysaccharide (LPS), hi...
