Abstract
Description
technical field
[0001] The invention relates to a feed additive, in particular to an anti-heat stress feed additive for dairy cows. Background technique
[0002] Dairy cows are afraid of heat but not cold. In summer, milk production often decreases due to hot weather. Heat stress of dairy cows is one of the most important reasons for the decline of milk production performance, reproductive performance and immunity of dairy cows in summer. Due to the long high temperature in summer, heat stress will cause huge economic losses in the dairy industry. Therefore, dairy cows are resistant to heat stress The research on the mechanism and its countermeasures has received extensive attention both at home and abroad. The main measures to alleviate the heat stress of dairy cows include improving the environment, regulating nutrition and breeding methods. At present, nutritional regulation is mainly used, supplemented by environmental improvement. Therefore, when choosing anti-heat str...
Examples
Embodiment 1
[0019] An anti-heat stress feed additive for dairy cows, comprising 7 parts by weight of astragalus, 3 parts of angelica, 4 parts of blancia, 2 parts of licorice, 5 parts of potassium chloride, 2 parts of sodium chloride, and 1 part of magnesium chloride 2 parts, 2 parts of sodium bicarbonate, 2 parts of citric acid, 5 parts of anhydrous glucose. Superfinely pulverize astragalus, angelica, buliuxing, licorice, potassium chloride, sodium chloride, magnesium chloride, sodium bicarbonate, and citric acid, pass through a 100-200-mesh vibrating sieve, and then mix with anhydrous glucose according to the proportion, The mixture is evenly stirred, sterilized, cooled and packaged to prepare an anti-heat stress feed additive for dairy cows.
Embodiment 2
[0021] An anti-heat stress feed additive for dairy cows, which weighs 4 parts of astragalus, 6 parts of angelica, 7 parts of vaccinia, 5 parts of licorice, 8 parts of potassium chloride, 5 parts of sodium chloride and 2 parts of magnesium chloride by weight. Parts, 5 parts of sodium bicarbonate, 5 parts of citric acid, 10 parts of starch. Superfinely pulverize astragalus, angelica, blancia, licorice, potassium chloride, sodium chloride, magnesium chloride, sodium bicarbonate, and citric acid, pass through a 100-200-mesh vibrating sieve, then mix with starch according to the ratio, and stir evenly , sterilized, cooled, and packaged to produce an anti-heat stress feed additive for dairy cows.
Embodiment 3
[0023] An anti-heat stress feed additive for dairy cows, which weighs 5 parts of Astragalus membranaceus, 5 parts of Angelica sinensis, 5 parts of Wangbuliuxing, 4 parts of licorice, 7 parts of potassium chloride, 4 parts of sodium chloride and 2 parts of magnesium chloride by weight.
