Cow feedstuff additive, cow feedstuff, and preparation methods thereof

Abstract

The invention discloses a cow feedstuff additive, a cow feedstuff, and preparation methods thereof. According to the invention, the cow feedstuff additive is composed of 0.01-0.5 parts of aspergillus oryzae, 0.01-0.5 parts of rumen-protected chlorine chloride, and 0.01-0.5 parts of malic acid. The cow feedstuff is composed of the additive, rice bran meal, 5% premix, corn, sesame meal, cottonseed meal, silage, purple medic, DDGS, windmill palm meal, sesame-seed cake, and calcium monohydrogen phosphate. The preparation method of the cow feedstuff comprises three steps of a premixing procedure, a secondary raw material mixing procedure, and a granulating and a mixing procedure. In the third step, a granular feedstuff is mixed with roughage. When the additive is added to the feedstuff for feeding cows, body temperatures of cows in hot summers can be substantially reduced; heat stress influences can be reduced; appetite of cows can be improved; foraging can be improved; and milk yield can be effectively improved. The cow feedstuff provided by the invention is advantaged in abundant and balanced nutrients. With the feedstuff, rectal temperatures of cows can be substantially reduced; heat stress influences can be reduced; milk yield can be effectively improved; and the milk quality can be ensured.

Description

technical field [0001] The invention belongs to the field of livestock feed, and in particular relates to an anti-heat stress dairy cow feed additive and a dairy cow feed. Background technique [0002] With the improvement of people's living standards, the demand for milk quality is increasing day by day, and there are higher requirements for the quality of milk. In midsummer, the climate is hot and the air is humid, which causes the body temperature of dairy cows to rise, which can easily cause heat stress in dairy cows. Heat stress in dairy cows refers to the non-specific response of the body when cows are stimulated by excessively high temperatures that exceed their own thermoregulation capabilities. Heat stress has become one of the important factors that endanger dairy husbandry, and heat stress has become the most popular research field in the world. [0003] The suitable ambient temperature for adult dairy cows is 5-25°C. When the ambient temperature exceeds 25°C or...

AI Technical Summary

Problems solved by technology

At present, many dairy farmers use antibiotics to control the impact of heat stress on dairy cows, but this leads to the production of a large number of resistant milk, which endangers people's health and reduces the economic benefits of the majority of dairy farmers
