Embodiment 1

[0013] Embodiment 1: sheep feed mainly is corn and wheat stalk, is 100% with sheep feed total amount, adds the lactic acid bacteria of 6wt%, and the activity of lactic acid bacteria is 1 * 10 8 cfu / g. Taking 5 goats as the experimental subjects, the content of Escherichia coli O157:H7 in the excreta was determined. Taking the feed without lactic acid bacteria as a control, the decrease of E. coli O157:H7 content in excreta was calculated.

[0014] Decrease = the number of Escherichia coli O157:H7 in the blank group / the number of Escherichia coli O157:H7 in the experimental group.

Embodiment 2-3

[0015] Example 2-3: similar to Example 1 except that the composition and types of additives are different, wherein the total amount of additives is 6wt%, see Table 1 for details.

Abstract

The invention provides a sheep feed additive capable of inhibiting Escherichia coli O157:H7. The sheep feed additive contains medium chain fatty acid and probiotic, wherein the probiotic particularly refers to lactic acid bacteria with activity of 1*10<7>cfu / g-1*10<9>cfu / g, the medium chain fatty acid particularly refers to myristic acid, and the weight ratio of myristic acid to actic acid bacteria is 1:5.

Description

technical field [0001] The invention relates to a sheep feed additive, in particular to a sheep feed additive for inhibiting Escherichia coli O157:H7, and belongs to the technical field of breeding feed. Background technique [0002] Food poisoning incidents caused by food-borne pathogenic bacteria-Escherichia coli O157:H7 have been reported in many countries around the world. This bacteria can cause human hemorrhagic enteritis, and even cause hemolytic uremic syndrome or death. It has caused great harm to health and has become a worldwide public health problem. Escherichia coli O157:H7 can be transmitted through a variety of ways, among which food-borne, water-borne and human-to-human contact are the three main modes of transmission. The vast majority of E. coli O157:H7 outbreaks are caused by food poisoning. In my country, the main hosts of Escherichia coli O157:H7 are cattle and sheep, followed by pigs, chickens, ducks and other livestock, poultry, flies and other insec...
