Complex bacterium agent for lamb complete feed fermentation

Abstract

The invention relates to a complex bacterium agent for lamb complete feed fermentation, the active ingredients of the complex bacterium agent comprise a lactobacillus inoculant, a bacillus subtilis inoculant, aspergillus oryzae and penicillium expansum, the bacteria are prepared according to the weight ratio of (1-2): (1-2): (1-2): (1-2): (1-2), and the total quantity of the complex bacterium agent is 0.5 * 10 < 9 >-2.86 * 10 < 9 > cfu / g. The method for fermenting the lamb complete feed by using the complex bacterium agent comprises the following steps: step 1, adding the complex bacterium agent into the lamb complete feed according to the addition amount of 0.2-0.6%, adjusting the humidity of the feed to be 40-50%, and carrying out sealed fermentation at 40 DEG C for 12-36 hours to obtain a fermented material; and step 2, mixing the fermented material with the lamb complete feed according to a mass ratio of 1: 6 to obtain the complex bacteria fermented feed. Compared with the prior art, the complex bacterium agent has the advantages that the feed cost is effectively reduced, the immunity and disease resistance of lambs are improved and the intestinal microecological balance of the lambs is regulated under the condition that the growth performance, health condition and carcass quality of the lambs are not influenced.

Description

technical field [0001] The invention relates to the field of composite bacterial agents, in particular to a composite bacterial agent for fermentation of full-price lamb feed. Background technique [0002] In recent years, mutton production in the world has shifted from adult mutton to lamb. Lamb is deeply loved by consumers for its high nutritional value, tender meat, unique flavor, and good taste. At the same time, lamb fattening has With the characteristics of fast weight gain, high feed remuneration, low product cost, short production cycle, and high economic benefits, the proportion of lamb fattening production in my country's mutton production is increasing year by year. [0003] At present, the fattening feed for lambs in rural areas in my country is mainly a simple combination of "straw + grain", which causes problems such as single feed raw materials, unscientific feed ratio, and imbalance of energy and protein, which affects the growth and development of lambs, and ...

[0003] At present, the fattening feed for lambs in rural areas in my country is mainly a simple combination of "straw + grain", which causes problems such as single feed raw materials, unscientific feed ratio, and imbalance of energy and protein, which affects the growth and development of lambs, and is even more serious Or, during the fattening process of mutton sheep, a large amount of high-protein, high-energy, and high-phosphorus feed was fed, but calcium supplementation was not paid attention to, resulting in an imbalance of calcium and phosphorus in the feed, which would cause excessive phosphate crystals in the urinary tract to form urine. Stones block the urethra and cause urolithiasis in fattened lambs, seriously affecting the economic benefits of fattened lamb production
