Summer fattening cattle daily ration

Abstract

The invention belongs to the technical field of animal threpsology, and relates to a summer fattening cattle daily ration. The summer fattening cattle daily ration is prepared from the following raw materials in percentage by weight: 20 to 30 percent of compound ammoniated treatment feed, 20 to 30 percent of silage, 10 to 15 percent of palm meal, 10 to 15 percent of corn germ meal, 10 to 15 percent of bran, 1 to 10 percent of sunflower seed meal, 1 to 5 percent of rice bran meal, 1 to 5 percent of medical stone, 0.5 to 1 percent of calcium powder, 0.5 to 1 percent of table salt and 1 percent of premix compounds. The summer fattening cattle daily ration has the advantages that a ruminal acidosis phenomenon of fattening cattle can be fundamentally eliminated; the cost of the cost fattening cattle daily ration is obviously reduced; the daily weight increase, the carcass weight, the dressing percentage, the pure meat percentage, the meat-bone ratio and the meat-fat ratio of the fattening cattle are obviously increased; and under the conditional shed raising conditions, the heat stress response of the fattening cattle in summer is obviously reduced.

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...

AI Technical Summary

Problems solved by technology

[0005] The current ration design theory for fattening cattle results in high feeding costs and high production risks, especially under heat stress conditions in summer. The dilemma of high concentrate syndrome has caused the beef cattle industry to fall into a long-term strategic development bottleneck.
