Heat-resistant stress feedstuff additive for milk cattle

Abstract

The invention relates to a feed additive, in particular to a heat-resistant stress feed additive for a cow. The additive comprises the following components in weight portion: 4 to 7 portions of milk veteh, 3 to 6 portions of angelica, 4 to 7 portions of seed cowherb, 2 to 5 portions of licorice, 5 to 8 portions of potassium chloride, 2 to 5 portions of sodium chloride, 1 to 2 portions of magnesium chloride, 2 to 5 portions of sodium bicarbonate, 2 to 5 portions of citric acid and 5 to 10 portions of carrier. The milk veteh, the angelica, the seed cowherb, the licorice, the potassium chloride, the sodium chloride, the magnesium chloride, the sodium bicarbonate and the citric acid are subjected to superfine grinding, filtered by a shaking screen of 100 to 200 meshes, and then mixed with the carrier according to a proportion, stirred evenly, sterilized, cooled, and packaged to prepare the feed additive. The feed additive can improve the heat-resistant stress reaction capability of the cow, enhance immune function of the cow organism, and promote quick rehabilitation of sick livestock, and has the effect of controlling breathing, tonifying the blood, and relaxing vein and promoting milk.

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...

Problems solved by technology

At present, anti-heat stress feed additives with dual functions of anti-heat and increasing milk mainly include probiotics, urea phosphate, methionine, nicotinic acid, sodium bicarbonate, sodium bicarbonate combined with magnesium oxide, sodium chloride and potassium chloride and Combined use of magnesium oxide, potassium carbonate, potassium chloride, isotopic acid, and Baoerkang, all of the above feed additives can resist heat stress and increase milk to varying degrees, and resist heat stress and increase milk according to different emphases. However, it cannot solve all the problems that arise during the process of cows' resistance to heat stress, and there are drug residues to varying degrees
