Millet straw leavening technology for mixed granulated feed for ruminants, and mixed granulated feed for ruminants

Abstract

The invention discloses a millet straw leavening technology for a mixed granulated feed for ruminants. The millet straw leavening technology comprises the following steps: (a) preprocessing raw materials: smashing whole millet straw into small segments; (b) activating bacteria: placing a millet straw leavening agent in a growth factor nutrient solution of which the temperature is 25-35 DEG C, and activating bacteria for 0.5-1.5 hours; (b) performing anaerobic leavening: uniformly mixing the millet straw leavening agent activated in step (b) with the raw materials smashed in step (a) according to 10-20% of inoculation amount, and leavening the mixture under the temperature of 20-35 DEG C and 40-60% of humidity for 4-7 days so as to obtained the leavened millet straw. The invention further discloses the mixed granulated feed for ruminants. The mixed granulated feed is obtained by processing refined materials and the leavened millet straw, wherein the refined materials comprise the following materials in percentage by weight: 26-30 wt% of corn, 30-35 wt% of millet, 12-13 wt% of bean meal, 14-16 wt% of cottonseed meal, 5-8 wt% of dried vinasse and soluble substances thereof, 1-2 wt% of fat powder, 0.8-1.2 wt% of sodium bicarbonate, 0.4-0.8 wt% of slow releasing urea, 0-2 wt% of molasses, 0.2-0.4 wt% of microbe feed additives, and 1-5 wt% of premix.

Description

technical field [0001] The invention relates to a fermentation process, in particular to a grain grass fermentation process that can be used for pellet feed. The grain grass fermented by the process can partially replace chingrass and alfalfa and be added to ruminant pellet mixed feed. In addition, the invention also relates to a granular mixed feed for ruminants containing the fermented aspartate grass. Background technique [0002] Millet is a small crop in my country's grain. Due to its high nutritional value and low yield, it is expensive. It is generally used as food for pregnant women and sick patients. There is no record of using it as a raw material for feed. [0003] Hybrid Valley "Zhang Zagu" is a series of millet hybrids successfully bred by researchers such as Zhao Zhihai from the Zhangjiakou Academy of Agricultural Sciences. After 40 years of unremitting efforts by two generations, they have overcome more than 30 key problems. It has the advantages of high yiel...

Problems solved by technology

[0004] However, due to the narrow sales volume of downstream millet products, after the high yield of "Zhang Zagu" in 2010-2012, there was a large backlog of millet. In the Xinzhou area of ​​Shanxi alone, there were instances where farmers could not sell 100,000 catties of millet in two years

In order to solve the problem of the outlet for hybrid grains after industrialization, the inventors have tried to add it to pig feed instead of corn. Although the breeding effect is good, due to the high price of millet, it is difficult for feed mills to accept it.
