Dedicated compound premix for milk secretion cows in summer and application thereof

Abstract

The invention relates to a dedicated compound premix for milk secretion cows in summer and an application thereof, relating to the technical field of animal feed. The compound premix is composed of the following components: ferric sulfate, manganese sulfate, copper sulfate, potassium iodide with a concentration of 1%, cobaltous sulfate with a concentration of 1%, vitamin A, vitamin D, vitamin E, nicotinic acid, vitamin C, yeast culture, organic chromium, dihydropyridine and the rest of carriers. The compound premix can ease the influence of high temperature in the summer on production property of cows, effectively maintain normal physiological functions of milk secretion cows in summer (normal body temperature and normal breathing frequency), effectively improve milk yield of the milk secretion cows against the high temperature environment in the summer, delay the trend of declining milk yield in the later stage of milk production of the milk secretion cows, enable the milk secretion cows to normally produce milk and reproduce against the high temperature environment in the summer, effectively avoid the high temperature environment from causing great economic losses to poultry raising industry, the daily cow industry in particular; the compound premix features convenience and safety, easy access to raw materials, dedicated use by cows in the summer, obvious effect, easy promotion and wide application prospect.

Description

technical field [0001] The invention relates to the technical field of animal feed. Background technique [0002] All warm-blooded animals have an optimal temperature zone, within this temperature zone, animals do not need to increase the energy required for maintenance. For lactating dairy cows, this zone is generally between -0.5°C and 20°C (J.W.West, 2003) , when the temperature rises above 25°C to 26°C, or the temperature and humidity index is higher than 72 (A.Berman 1985), it can cause heat stress in dairy cows. Stress response is the defense function of animals mobilizing the body. The heat stress of dairy cows refers to the sum of non-specific responses of dairy cows to the high temperature environment that is not conducive to physiological activities. The stress of dairy cows in summer is mainly formed by internal and external factors. The internal cause is that a large amount of heat will be generated during the physiological digestion process of dairy cows. In t...

However, most reports only add these additives to the dairy cow’s diet alone to improve the milk production of dairy cows, and have not considered the effect of the combined application of these substances
