A kind of milk cow rumen fermentation accelerator

Abstract

The invention relates to a cow rumen fermentation accelerator, which comprises bacterial broth and complex carbohydrate, wherein the weight ratio of the bacterial broth to the complex carbohydrate is 1:1-2, the bacterial broth comprises 1.0-2.0 * 1010CFU / ml beer yeast, 1.5-2.0 * 1010CFU / ml bacillus subtilis, 1.5-2.0 * 1010CFU / ml bacillus licheniformis, 1.0-2.0 * 109CFU / ml lactic acid bacteria, and 1.0-2.0 * 109CFU / ml aspergillus oryzae. The complex carbohydrate comprises 60-70 percent by weight of lactose, 15-25 percent by weight of fructose, 4-6 percent by weight of fumaric acid, 2-4 percentby weight of malic acid, 4-6 percent by weight of sodium bicarbonate and 1-3 percent by weight of magnesium oxide. Due to the cow rumen fermentation accelerator disclosed by the invention, the activity of cow rumen microorganism can be improved, the degradation of coarse fodder in rumen is promoted, the utilization ratio of nitrogen is improved, the output of MCP is increased, and thus the purpose of promoting the function of cow rumen fermentation is achieved.

Description

technical field [0001] The invention relates to a feed additive for improving the production performance of dairy cows, in particular to a ruminal fermentation accelerator for dairy cows composed of microbial fermentation liquid and complex sugars. Ecological agents and rapidly degrading carbohydrates. It belongs to the technical field of A23K1 / 18(2006.01)I in the IPC International Patent Classification. Background technique [0002] Dairy cows are ruminants, and their health and production efficiency mainly depend on the functional state of the rumen. The rumen is a living fermenter for the inoculation and propagation of anaerobic microorganisms. The stable environment in the rumen (mainly the relative stability of temperature, pH, osmotic pressure and moisture in the rumen) is very suitable for the reproduction of anaerobic microorganisms. When microorganisms fully reproduce in the rumen, they secrete various digestive enzymes. These digestive enzymes can convert a large...

Problems solved by technology

[0010] Although the dairy cow rumen regulating agent given by the above technical scheme can promote and maintain the balance of microbial flora in the rumen, stabilize the pH value of the rumen, alleviate the acidosis of dairy cows caused by high-concentrate feed, and improve the utilization rate of roughage by dairy cows, they do not take into account The lack of fast-degradable carbohydrates in low-quality straw and the excess of fast-degradable nitrogen sources in concentrate feed lead to a contradiction in the asynchronous release of energy nitrogen in the rumen

At the same time, the above technical scheme is to directly provide microorganisms for the rumen, or provide growth substrates for rumen microorganisms, so as to achieve the purpose of improving rumen function, and the regulation method is single
