Embodiment Construction

[0027] The selection, treatment and feeding management of test animals when the feed added with different anti-heat stress agents for dairy cows is used for experiments.

[0028] Prepare a compound anti-heat stress agent for dairy cattle (1000 g) according to the formula: 20 g of coated betaine, 10 g of compound enzyme preparation, 200 g of potassium chloride, 220 g of magnesium oxide, and 550 g of carrier (corn cob powder).

[0029] The coated betaine is provided by Jiangsu Yixing Tianshi Feed Co., Ltd., and the content of betaine in the coated betaine is 40%, which can be prepared by the following preparation method:

[0030] ①Take 100kg of 67.5% pure betaine lye, heat it to 80°C, add it into the mixer, then add 89kg of 20-30 mesh white carbon black, mix and stir it into a solid, and then dry it through a granulator to obtain the betaine content 42% betaine white carbon black particle 160kg, standby;

[0031] 2. Get 5kg of hydroxypropyl methylcellulose, dissolve it with 95k...

Abstract

The invention belongs to the field of production of feed additives and discloses a composite heat stress resisting agent for a dairy cow and an application of the composite heat stress resisting agent. The composite heat stress resisting agent for the dairy cow comprises the following ingredients in percentages by mass: 1-5% of enveloped betaine, 0.5-2% of composite enzyme preparation, 15-25% of potassium chloride, 18-26% of magnesium oxide and 50-60% of carrier. The invention also provides the application of the composite heat stress resisting agent for the dairy cow in preparation of a feed for improving the heat stress resisting performance of the dairy cow, and the heat stress resisting agent is added at the dose of 1% of the feeding amount of fine feed for the dairy cow. The composite heat stress resisting agent can be used for supplementing potassium, magnesium, active methyl and exogenous enzyme, relieving the heat stress of the dairy cow due to high temperature in summer, promoting the lactation of the dairy cow, improving the milk ingredient, improving the immunity of the organism, reducing the number of somatic cells in the milk, and improving the oxidation resistance of the dairy cow; and therefore the composite heat stress resisting agent can achieve the effects of preventing diseases and caring health, and is conductive to the improvement of the health of the dairy cow and the quality of a milk product.

Description

technical field [0001] The invention belongs to the field of feed additive production, and relates to a compound anti-heat stress agent for dairy cows and its application, in particular to a compound anti-heat stress agent for dairy cows containing betaine, a compound enzyme preparation, and a potassium-magnesium compound, which is specially used for heat resistance of dairy cows in summer Production of stress feed. Background technique [0002] The dairy cows raised in my country are mainly Holstein cows, whose biological characteristics are resistance to cold and heat. Heat stress in summer is one of the main problems plaguing dairy farms, and it is also one of the hot spots in the field of dairy cow research at home and abroad. With various new Technology is applied in dairy cow production, and the production level of dairy cows in my country is constantly improving. In 2011, the yield per cow has reached 4800kg, and the heat stress caused by high temperature in summer is ...
