Composition for relieving heat stress of dairy cows as well as preparation method and application of composition

Abstract

The invention provides a composition for relieving heat stress of dairy cows as well as a preparation method and application of the composition, and belongs to the technical field of compositions. The composition comprises 13 to 16 g of NCG, 5 to 10 g of gamma aminobutyric acid, 600 to 1000 IU of vitamin E, 20 to 50 mg of vitamin C, 3 to 6 g of purslane, 3 to 6 g of dandelion and 2 to 5 g of saccharomyces cerevisiae boulardii. The invention further provides a preparation method of the composition for relieving the heat stress of the dairy cow. The invention also provides an application of the composition as an additive in preparation of a feed for relieving heat stress of dairy cows. The composition provided by the invention can relieve the influence of heat stress of dairy cows by enhancing the digestive absorption capacity of intestinal tracts of dairy cows, improving the nutrition utilization efficiency of dairy cows, improving immunity, clearing away heat and toxic materials, cooling blood and relieving summer-heat, and achieves the purpose of maintaining or increasing the milk yield of dairy cows in summer.

Description

technical field [0001] The invention belongs to the technical field of compositions, and in particular relates to a composition for relieving heat stress of cows, a preparation method and application thereof. Background technique [0002] Cow is a kind of animal with "physiological heat-resistant characteristics". When dairy cows are stimulated by high temperature in summer, their body temperature will rise, their breathing will speed up, their skin metabolism will be impaired, their appetite will decrease, and their feed intake will decrease; the nutrition in their bodies will be in negative balance. The cows lose weight and body condition; milk production, milk fat rate, and milk protein rate decrease at the same time, the reproductive rate decreases, and the disease and mortality increase, which directly affects the economic benefits of the farm. There are many ways to alleviate the heat stress of dairy cows, mainly in terms of nutrition, environment, management, etc., am...

AI Technical Summary

Problems solved by technology

[0023] In the prior art, measures such as increasing the concentration of energy and protein in the diet and reducing the ratio of coarse material are mainly adopted to ensure that the nutrient intake of dairy cows does not decrease while the total feed intake is reduced. , to suppress the decline in milk production, but it is difficult to obtain the desired effect

Other techniques include using hormones to treat cows, but it will cause hormone residues, affect milk quality, and at the same time, harm the health of cows

There is also a technology of using Chinese herbal medicine to relieve the heat stress of dairy cows, but the cost is high and it is not easy to be widely promoted
