Embodiment 1

[0057] In a back-up cattle workshop of a dairy farm, 40 Holstein cows aged 11 to 16 months were selected and divided into an experimental group and a control group according to a randomized block design. The diet consists of: 1.95 kg of corn, 0.3 kg of soybean meal, 0.24 kg of cottonseed meal, 0.39 kg of bran, 10 kg of corn silage, 3 kg of brewer's grains, 0.12 kg of premix, and ad libitum feeding of hay. 50 grams of the product was divided into 2 times and mixed with concentrate to add feeding, and the control group did not add. The test cows were reared in groups with variable troughs, and were fed in troughs three times a day with an interval of 7-8 hours.

[0058] During the test period of 34 days, after adding the product of the present invention, the feed intake and feed intake speed of the test cattle were normal, and the average daily gain of the test group was 1.13 kilograms, which was 46.75% higher than that of the matched group. The improvement in the control group...

Embodiment 2

[0068] In the adult cow workshop of a dairy farm, 38 healthy adult Holstein dairy cows were selected, and were paired into an experimental group and a control group, 19 cows in each group, according to the principle of similar age, parity, lactation month, and daily milk production. The diet consisted of: 1.01 kg of corn stalks, 3.01 kg of corn stalk powder, 0.39 kg of Leymus chinensis, 13.79 kg of corn silage, 4.58 kg of brewer's grains, 0.22 kg of dry meal, 1.8 kg of carrots, and 9.76 kg of concentrate. 50 grams of the invention product is divided into 2 times and mixed with fine material to add and feed, and the control group does not add. The test cows were fed three times a day, and milked three times by mechanical pipes, with an interval of 7 to 8 hours.

[0069] After 35 days of experimentation, the test group increased milk production by 1.79 kg per day, and the control group increased milk production by 0.06 kg per day. Compared with the control group, the test group ...

Abstract

A dual-effect microbial feed additive for ruminant is prepared through pulverizing corn, steaming, liquefying, saccharified, inoculating lactobacillus acidophilus and saccharomyce cerevisiae, fermenting to obtain living bacterium preparation, culturing bacillus subtilis, aspergillus oryzae and aspergillus niger in the culture medium prepared from corn, bran and soybean dregs, fermenting to obtain composite enzyme preparation, and proportionally mixing said living bacterium preparation with said composite enzyme preparation. It can promote the growth and health of ruminant and increase the utilization rate of feed.

Description

A technical field [0001] The invention relates to a special dual-effect microbial feed additive for ruminants and a preparation method thereof, belonging to the technical field of microbial feed additives. Two background technology [0002] Feed safety is a major issue of widespread concern around the world. Drug residues and pathogenic bacteria resistance caused by adding antibiotics and specific drugs to feed have become a global problem. More and more countries have adopted legislation to prohibit the abuse of antibiotics and drugs. The development of new and safe microbial feed additives, which can replace or partially replace antibiotics and drugs in livestock and poultry farming, has a positive effect on alleviating feed and food safety problems such as drug residues and pathogenic bacteria resistance in animal products, and ensuring human health. significance. [0003] Due to their unique physiological characteristics, ruminants can use low-value green roughage and ...
