Feed additive for increasing milk cow dairy food quality and milk cow anti-heat stress

Abstract

Feed additive for increasing milk cow dairy quality and milk cow anti-heat stress relates to a feed additive. The additive comprises calcium conjugated linoleic acid, selenium and vitamin E, the ratio of the additive is 15-50mg selenium of and 25,000-750,000 IU of vitamin E to each 1 Kg of calcium conjugated linoleic acid. The invention has the advantages that the yield of milk fat of milk cows, the contents of unsaturated fatty acid in milk fat and the selenium and VE in milk are increased, thus improving the dairy quality, the heat stress reaction of milk cows can also be alleviated, thus increasing the milk production , furthermore, the active oxygen in the heat stress milk cows can be reduced to decrease peroxidation reaction, thus reducing the injure of heat stress on milk cows and increasing the anti-oxidation ability of milk cow organism. The invention has the advantages of simple production process, no requirement of special equipment, safe and simple operation and no side effect.

Description

technical field [0001] The invention relates to an animal feed additive, in particular to a feed additive for improving the quality of milk products of dairy cows and resisting heat stress of dairy cows. Background technique [0002] Conjugated linoleic acid (CLA for short, the same below) has many biological functions beneficial to human health, such as anti-cancer, anti-oxidation, enhancing immunity, reducing fat deposition, promoting growth and preventing cardiovascular diseases and diabetes. In 1996, the NRC listed conjugated linoleic acid as the only animal source fatty acid with anti-cancer effects. Ruminant products are the main source of conjugated linoleic acid in human food. Conjugated linoleic acid is the most abundant. Therefore, it is of great significance to human health to increase the content of conjugated linoleic acid in milk fat of dairy cows and improve the quality of milk. The literature "Kelly et al., J Nutr, 1998:881-885)" reported that directly addi...

AI Technical Summary

Problems solved by technology

However, there is a problem that although the relative content of conjugated linoleic acid in milk fat is increased, it will reduce the milk fat rate at the same time

Heat stress can also cause changes in antioxidant indicators in dairy cow serum, leading to an imbalance in the body's antioxidant system
