Application of tea saponin in improving milk production performance of dairy cows

Abstract

The invention discloses an application of tea saponin in dairy cow milk production performance improving and belongs to the application field of tea saponin. Different doses of tea saponin are added on the basis of dairy cow daily diet, and the influence on dairy cow milk production performance and milk quality from the tea saponin is inspected. The results show that when the adding amount of the tea saponin is 20-40 g / d, dairy cow milk production amount can be improved, the milk-fat content of cow milk is improved, the urea nitrogen content in cow milk is lowered, the saturated fatty acid content can be lowered obviously, and n-3 / n-6 fatty acid ratio is improved. Accordingly, the tea saponin can be used as feed additives to be used for improving dairy cow milk production performance or cow milk quality.

Description

Technical field [0001] The invention relates to a new use of tea saponin, in particular to the use of tea saponin in improving milk production performance of dairy cows, and belongs to the application field of tea saponin. Background technique [0002] In the process of dairy cattle breeding, the production performance and disease resistance of dairy cows will be affected by factors such as the external environment, feed nutrition level and pathogenic microorganism invasion. These factors will directly affect the production efficiency of dairy cows. As consumers' demand for cow's milk increases year by year, the requirements for milk quality have become more stringent. Although China's milk production has increased every year, milk quality problems have occurred frequently, which has seriously affected the sales and exports of milk products. [0003] Tea saponin (C 57 H 90 O 16 ) Is an ester saponin isolated from Camellia plants. Pure tea saponin is a white fine columnar crystal....
