Description
Technical field
The utility model relates to Photoelectric Detection field, is specially a kind of aflatoxin contamination feed examination device.
Background technology
Aflatoxin is one of major pollutants in grain agricultural product, is mainly present in peanut, corn, Cottonseed Meal, dregs of beans and their accessory substance.Livestock and poultry eat the feed that contains aflatoxin or thalline, even touch and also can occur morbidity or locality damage in various degree after the material that contains this toxin.Aflatoxin can reduce feed nutritive value and the utilization factor of livestock and poultry to nutrient, makes sense organ and the palatability variation of feed, causes livestock and poultry feed intake to reduce, and production performance declines.Aflatoxin can also suppress digestive enzyme activity in livestock and poultry body, causes nutritional labeling to absorb and dysbolism, causes livestock and poultry digestive function impaired, and weightening finish slows down and the stagnation etc. of growing.It is wide that aflatoxin has distribution, and livestock and poultry are damaged to serious feature, can cause heavy losses to aquaculture.Once livestock and poultry aflatoxicosis disease occurs, do not have methods for the treatment of especially targetedly.If there is aflatoxin acute and chronic poisoning, first to stop to be immediately fed with the feed of aflatoxin, be replaced by the feed without aflatoxin contamination.The key that prevents livestock and poultry generation aflatoxicosis problem is not allow the feed that contains aflatoxin be eaten by livestock and poultry.Therefore the aflatoxin in feed being detected is the effective measures that ensure livestock birds health.Obtain the situation that feed is subject to aflatoxin contamination the development of aquaculture is highly profitable, to go out the aflatoxin in feed be the significant process that realizes this target in examination rapidly.
Due to the skewness of aflatoxin in feed, aflatoxin only, in the time that temperature and humidity reaches the point of optimal condition of producing exotoxin, could produce in a large number.Aflatoxin is the material that is relatively difficult to Accurate Determining, and each step of mensuration is accompanied by the generation of error, and wherein maximum source of error is in sampling process.If expect that representative sample just needs a large amount of samplings, but a large amount of sampling can increase again man-hour, improves testing cost.
