So far, do not see the report of the effect of hexachlorophene resisting Eimeria tenella as yet, can't infer by the known character of hexachlorophene whether it has the effect of resisting Eimeria tenella.
Summary of the invention
The object of the present invention is to provide the application of hexachlorophene at resisting Eimeria tenella.
The present invention is added into powder in the feedstuff and mixing by hexachlorophene and acceptable auxiliary are made powder afterwards, is mixed with the described hexachlorophene of 15 grams in per 100 kilograms of feedstuffs, by daily forage volume feeding chicken; Or hexachlorophene and acceptable auxiliary made suspending agent, and suspending agent to be mixed in drinking water, the concentration that makes hexachlorophene is 7.5g/100Kg water, by daily amount of drinking water feeding chicken.Anticoccidial index (ACI) by zoogenetic infection experiment confirm hexachlorophene reaches more than 168.8, has resisting Eimeria tenella effect preferably.
The specific embodiment
Specify the anti-chicken coccidiosis experiment of hexachlorophene below:
Material:
Control drug: by the coccidiostat three word coccidiosis powder (30% sulfaclozine sodium, lot number 001010) of Shanghai Novartis animal health company limited production.
Hexachlorophene: get 30g hexachlorophene (content is not less than 99%) and 70g starch mixing, promptly can be made into powder, described powder is admixed feedstuff, make and be mixed with the described hexachlorophene of 15 grams in per 100 kilograms of feedstuffs; Perhaps get 30g hexachlorophene (content is not less than 99%) and add propylene glycol and stir, fixed moltenly can form suspending agent to 100 milliliters, described suspending agent is mixed in drinking water, the concentration that makes hexachlorophene is 7.5g/100Kg water.
Coccidian oocyst: Eimeria tenella (Eimeria tenella) Guangdong strain spore egg capsule, preserve rejuvenation in non-ball worm chickling body before using by the Guangdong Provincial Academy Of Agricultural Sciences Veterinary Institute.
Chickling: the yellow chickling in the south of the Five Ridges, provide by Animal Husbandry Inst., Guangdong Prov. Academy of Agricultural Sciences, raise in the special-purpose Animal House of disinfectant; Chicken coop and the equal strict sterilization of used vessel, free choice feeding and drinking pure water; Observe chickling before the experiment and have or not clinical symptoms and continuous 2d to check that feces has or not coccidian oocyst, standby.
Feedstuff:, do not contain any coccidiostat by the Xin Nan of Guangdong Province feed corporation,Ltd customization material of brooding all.
Experimental technique:
Grouping: press experiment grouping and processing with yellow breeding chickling to 10 age in days in 150 south of the Five Ridges, pursue and only weigh, eliminate weak young bird and the excessive person of body weight, will remain chickling and be divided into 5 groups at random, 30 every group, and suitably adjustment makes every group of chickling TBW about equally.
Handle: except that the 1st (blank) group, all the other are respectively organized the equal per os of chickling and gavage Eimeria tenella spore egg capsule 1 * 10
5Individual/plumage; Except that I group and II (positive control) group, all the other are respectively organized chickling and all feed immediately after infection or drink feedstuff or the water that contains coccidiostat.
Observation every day and record chicken group's mental status, feed intake, feces situation etc.; Dead chickling is weighed, cuts open inspection, if Eimeria tenella infect cause death then lesion score be+4 minutes; All chickling were cutd open inspection by only weighing in the 7th day in the infection back, carried out caecum lesion and kept the score; Calculate the weightening finish and the price of deed of respectively organizing chickling at last.The grouping situation of experiment chickling sees Table 1.
