A kind of compound feed mildew-resistant antidote
Art
The present invention relates to a kind of feed addictive, be specially mixed feed mould inhibitor toxic agent; The invention still further relates to the preparation method of this mildew-resistant antidote.
Background technology
China is livestock-raising big country, and required feedstuff consumption is large, and kind is many.And feedstuff very easily goes mouldy in the process of harvesting, storage, be unfavorable for follow-up production and application.To deposit in process at storage to prevent feed and go mouldy, in feed formula, generally add mould inhibitor.What current use was more is based on the single or composite type mouldproof agent of organic acid salt (as calcium propionate etc.), composite organic acid (as propionic acid etc.) and propionic acid ammonium system.This type of mould inhibitor has following deficiency: have certain excitant and corrosivity, affects the palatability of feed, causes efficiency of feed utilization to reduce; Main dependence slow release fumigation is used for reaching suppression growth of microorganism, and aequum is large, adds cost higher (common addition is about 2 kilograms/ton).Meanwhile, in present feed, there is the pollution problem of some poisonous and harmful substances, as the safety of the serious harm feeds such as mercury, cyanide, nitrite.In order to solve the problem comprehensively, need to occur that a kind of proportioning is simple, easy to use, safe and effective, a kind of composite mildewproof antidote of good palatability.
Garlic oil (Allicin) is a kind of organosulfur compound extracted from the bulb (garlic) of Liliaceae allium garlic (Allium Sativum), also be present in onion and other alliums, formal name used at school is Diallytrisin.There is the effect of the toxicity reducing the nuisances such as mercury, cyanide, nitrite, simultaneously can to Escherichia coli, salmonella, staphylococcus aureus, shigella dysenteriae, typhoid bacillus, pneumococcus, the harmful bacterias such as streptococcus have obviously suppression and killing action, and can effectively kill various mould, mildew-proof function is remarkable, extend the feed shelf-life, improve feeding environment.
Summary of the invention: provide a kind of mixed feed mildew-resistant antidote, by the double action of sterilizing of tagging, stifling sterilization, under condition of the same race, has anti-mold effect good, effect that fresh keeping time is long.This mildew-resistant antidote is often planted composition and is all met forage health standard, has again feature with low cost safely, efficiently, lastingly simultaneously.
1, mixed feed mildew-resistant antidote of the present invention, its component and weight proportion as follows:
Garlic oil 20-25%
Propionic acid 2-4%
Calcium propionate 15-20%
White carbon 10-25%
Bentonite 25-45%
2, a mixed feed mildew-resistant antidote, its production stage is as follows:
A, take the garlic oil of 20-25 weight portion, the propionic acid of 2-4 weight portion, the white carbon of 10-25 weight portion drops in mixer and mixes, and incorporation time is 10-15 minute.
B, take the calcium propionate of 15-20 weight portion, bentonite and the said mixture of 25-45 weight portion carry out secondary and mix in mixer, through sieving, checking, pack, namely obtain Midew preventive for feed of the present invention.
Embodiment 1
A, take the garlic oil of 20 weight portions, the propionic acid of 4 weight portions, the white carbon of 20 weight portions drops in mixer and mixes, and incorporation time is 10-15 minute.
B, take the calcium propionate of 18 weight portions, bentonite and the said mixture of 38 weight portions carry out secondary and mix in mixer, through sieving, checking, pack, namely obtain Midew preventive for feed of the present invention.
Embodiment 2
A, take the garlic oil of 20 weight portions, the propionic acid of 2 weight portions, the white carbon of 15 weight portions drops in mixer and mixes, and incorporation time is 10-15 minute.
B, take the calcium propionate of 20 weight portions, bentonite and the said mixture of 43 weight portions carry out secondary and mix, through sieving, checking in mixer
Inspection, packaging, namely obtain Midew preventive for feed of the present invention.
Embodiment 3
A, take the garlic oil of 25 weight portions, the propionic acid of 2 weight portions, the white carbon of 20 weight portions drops in mixer and mixes, and incorporation time is 10-15 minute.
B, take the calcium propionate of 20 weight portions, bentonite and the said mixture of 33 weight portions carry out secondary and mix in mixer, through sieving, checking, pack, namely obtain Midew preventive for feed of the present invention.
Embodiment 4
A, take the garlic oil of 25 weight portions, the propionic acid of 4 weight portions, the white carbon of 25 weight portions drops in mixer and mixes, and incorporation time is 10-15 minute.
B, take the calcium propionate of 18 weight portions, bentonite and the said mixture of 28 weight portions carry out secondary and mix in mixer, through sieving, checking, pack, namely obtain Midew preventive for feed of the present invention.
According to the Midew preventive for feed that the inventive method is produced, compared with prior art, there is following beneficial effect:
Cost of material is low, originates guaranteed; Biological safety is high, all meets forage health standard; Namely can tag sterilizing, have again stifling bactericidal action concurrently, under condition of the same race, anti-mold effect is good, and fresh keeping time is long.When consumption is 3-5%, can make the feed of less than 14% preserve two months not mouldy.
