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
The present invention relates to a kind of sheep feed additive, particularly a kind of sheep feed additive that is used to suppress Escherichia coli O 157: H7 belongs to the breeding feed technical field.
Background technology
A plurality of countries are in the news the food poisoning that is caused by food-borne pathogens-Escherichia coli O 157: H7 in the whole world; This bacterium can cause people's hemorrhagic enteritis; Even cause and hemolytic uremic syndrome or death human health is caused very big harm, become worldwide public health problem.Escherichia coli O 157: H7 can propagate through number of ways, and wherein eating source property, water and interpersonal the contact is three big main circulation ways.Most Escherichia coli O 157s: the H7 epidemic causes because of food poisoning.Main host at China's Escherichia coli O 157: H7 is ox, sheep, secondly is also to detect pathogen in insects such as livestock and poultries such as pig, chicken, duck, fly and the wild animal, and microbiological contamination food mainly contains ox, sheep, pig, chicken, fresh vegetables and salted vegetables etc.
At present, the strategy that reduces Escherichia coli O 157: H7 before butchering mainly contains and adds antibiotic substitute and probiotic.Aliphatic acid is used for antibacterial certain research having been arranged, but the composite research of probiotic and aliphatic acid does not also have.
Summary of the invention
The objective of the invention is to provide a kind of inhibition Escherichia coli O 157: the sheep feed additive of H7, this additive can significantly suppress the Escherichia coli O 157 in the sheep body: H7.
A kind of inhibition Escherichia coli O 157: the sheep feed additive of H7, it contains medium chain fatty acid and probiotic.
Wherein medium chain fatty acid is a C8-C14 aliphatic acid.
Wherein probiotic is lactic acid bacteria (Lactobacili).
Wherein lactic bacteria activity is: 1 * 10
7Cfu/g-1 * 10
9Cfu/g.
Wherein medium chain fatty acid is nutmeg acid.
Wherein the weight ratio of medium chain fatty acid and probiotic is: 1: 1-10.
Wherein the weight ratio of medium chain fatty acid and probiotic is: 1: 1-5.
Beneficial effect: the ability that has strengthened inhibition Escherichia coli O 157: H7 through the synergy of probiotic and medium chain fatty acid.
The specific embodiment
Embodiment 1: the sheep feed is mainly corn and wheat straw, is 100% with sheep feed total amount, adds the lactic acid bacteria of 6wt%, and the activity of lactic acid bacteria is 1 * 10
8Cfu/g.With 5 goats is experimental subjects, measures Escherichia coli O 157 in the excreta: H7 content.With the feed that does not add lactic acid bacteria is contrast, calculates Escherichia coli O 157 in the excreta: the decline of H7 content.
Slippage=blank control group Escherichia coli O 157: H7 number/experimental group Escherichia coli O 157: H7 number.
Embodiment 2-3: different with the composition and the kind of embodiment 1 similar just additive, wherein the total amount of additive all is 6wt%, specifically sees table 1.
Table 1 embodiment 1-3
| Composition | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| Lactic acid bacteria (wt%) | ?6 | ?3 | |
| Nutmeg acid (wt%) | ?6 | ?3 | |
| Slippage (doubly) | ?1000 | ?1100 | ?1700 |
Embodiment 4-5: different with the composition of embodiment 3 similar just additives, specifically see table 2.
Table 2 embodiment 4-5
| Composition | Embodiment 4 | Embodiment 5 |
| Lactic acid bacteria (weight ratio) | ?10 | ?5 |
| Nutmeg acid (weight ratio) | ?1 | ?1 |
| Slippage (doubly) | ?1800 | ?2000 |
