[0014] Chinese patent CN102247570B discloses a traditional Chinese medicine composition for treating dairy cow ketosis. 58 cases of cow ketosis were treated with this traditional Chinese medicine composition, and the cure rate reached 86%. Cure the root cause, and the treatment effect on primary ketosis is not good
The advantages are to promote and maintain the balance of microbial flora in the rumen, stabilize the pH value of the rumen, alleviate the acid toxicity of cows caused by high concentrate, reduce the concentration of ammonia in the rumen, promote its utilization of nitrogen, and improve its micro-ecological environment, but mainly The above purpose is achieved by stimulating the reproduction of cellulolytic bacteria and lactic acid bacteria in the rumen, without targeted supplementation of beneficial bacteria required by the rumen

Abstract

The invention discloses a preparation method of a glucose precursor for improving dairy cow rumen flora, belonging to the technical field of dairy cow glucose precursors. A microbial preparation and a glucose precursor are taken as main raw materials to be scientifically compounded with Chinese herbal medicine extracts, compound enzymes and other nutrient substances, so that microbial flora needed by the rumen of a dairy cow and endogenous glucose needed for growth and physiology of the dairy cow are effectively replenished and maintained. Experiments prove that the daily milk yield of each dairy cow is increased by 16.81%, the first estrus time of the postpartum dairy cows is shortened by about 10 days, the conception rate of the postpartum dairy cows in the first estrus time is increased by 16.2%, the oestrus rate of the postpartum dairy cow groups is increased by 16%, and the occurrence rate of various diseases of the postpartum dairy cows is averagely reduced by 13.0%-30.5%. According to the preparation method of the glucose precursor disclosed by the invention, high-viscosity glycerol and propylene glycol are uniformly mixed with other materials, so the process is simple, the operation is convenient, the production efficiency is high, the material mixing effect is good and large-scale production can be realized.

Description

technical field [0001] The invention relates to a dairy cow glucose precursor, in particular to a preparation method for improving the glucose precursor of dairy cow rumen flora. Background technique [0002] In general, most of the sugars in ruminant diets form VFAs (volatile fatty acids) during rumen fermentation, and only a small amount of glucose is absorbed in the digestive tract. Adult ruminants have low blood sugar, but this does not mean that the significance of glucose metabolism can be ignored. As an important nutritional monosaccharide, glucose is an indispensable nutrient in all animals and plays an important role in animal cell metabolism. Insufficient glucose supply, cattle are prone to ketosis, and pregnant sheep are prone to toxemia, which seriously affects the growth and health of animals. Therefore, people have strengthened the research on glucose nutritional metabolism. With the wide application of isotope technology, people have a further understanding...
