Study on Immune Performance of Eimeria tenella Hybridization F2 Strain Attenuated by Chemical Preparation

LIU Chun-jie1,ZHANG Chun1,XU Jing1,YANG Gui-lian2,CAI Ya-nan3,ZHAO Quan21.Development College of Jilin Agricultural University,Changchun 130600,China;2.College of Animal Science and Technology,Jilin Agricultural University,Changchun 130118,China;3.College of Animal Science and Veterinary Medicine,Jilin University,Changchun 130062,China  
Eimeria tenella hybridization F2 strain oocysts were attenuated by chemical preparation.The 7-day old AA broilers were selected in this test.Attenuated hybridization F2 strain oocysts were inoculated to 3 groups of broiler to detect immune performance of E.tenella.The first immunity doses to be inoculated were 4×103,8×103,16×103 oocysts per group,and the second immunity doses were the same.The first immunity day was the 7th day,and the second was the 14th day.On the 21th day,broilers were attacked by using 5×104 wild strain oocysts per broiler.On the 7th day after attack,immune performance was detected through survival rate,relative weight gain rate,pathological change value,anticoccidial index(ACI),oocyst value,feces record and caecum lesion record,etc.The results showed that immune performance of E.tenella hybridization F2 strains oocyts attenuated by chemical preparation are much higher than that of those not attenuated and controlled,especially the immune effectiveness that was 8×103 attenuated E.tenella hybridization F2 strain oocyts to be inoculated is the optimal.
