Premix forfermented total mixed rations (TMR) for dairy cows and preparation process thereof

Abstract

The invention relates to a premix for fermented total mixed rations (TMR) for dairy cows, which comprises the following components: dairy cow fermented TMR complex enzyme, urease inhibitor, vitamins A and D, vitamin E, propionic acid-producing lactic acid bacteria, calcium formate, calcium sulfate, sodium salt, zinc sulfate pentahydrate, manganese sulfate pentahydrate, copper sulfate pentahydrate, 1 percent of iodine, 1 percent of selenium and 1 percent of cobalt. The premix is reasonably mixed, contains complete, rich and reasonably-proportioned nutrients and can accelerate the fermentation and in-vitro digestion of the fermented TMR, reduce the generation of ammoniacal nitrogen, be stored conveniently after fermentation, keep the health of dairy cows, fully meet the needs of rumen microorganisms for growth, supplement vitamins, macroelements and microelements to milk daily ration, prevent various diseases caused by the shortage of nutritive elements, promote the normal development of the dairy cows, effectively improve milk production period, milk yield and milk quality, regulate body metabolism and improve immunity and fertility.

Description

technical field [0001] The invention belongs to the technical field of dairy cow premix and its preparation, and in particular relates to a premix specially used for dairy cow fermentation TMR and a preparation process thereof. Background technique [0002] The TMR feeding method has obvious advantages compared with the traditional feeding method of separating fine and coarse. However, there are still the following restrictive factors in the development of TMR technology: First, in order to make all raw materials evenly mixed, special mechanical equipment is required for cutting or crushing straw and long grass; in order to ensure the nutritional balance of the diet, a mixing and Metering equipment, which requires a one-time investment of a large amount of money; in addition, professional maintenance and technical personnel are required. Moreover, TMR rations are generally required to be ready-to-use to ensure the supply of nutrients. Therefore, for most small and medium-si...

Problems solved by technology

However, there are still the following restrictive factors in the development of TMR technology: First, in order to make all raw materials evenly mixed, special mechanical equipment is required for cutting or crushing straw and long grass; in order to ensure the nutritional balance of the diet, a mixing and Metering equipment, which requires a one-time investment of a large amount of money; in addition, professional maintenance and technical personnel are required

Moreover, TMR rations generally require ready-to-use and ready-to-use to ensure the supply of nutrients. Therefore, for most small and medium-sized dairy farms and farmers, the application of TMR feeding technology has certain limitations.
