Comparison of Pathogenicity and Reproductivity between Virulent Strain and Precocious Strain of Eimeria acervulina
摘要
Abstract
In order to examine pathogenicity and reproductivity of virulent strain and precocious strain of Eimeria acervulina ,the mental state,clinical signs,weight gain,lesion scores and oocyst production of infected chickens were determined.The results showed that,oocyst production peak of precocious strain was at the 5th day and shorter 1 day than that of virulent strain,reproductivity of precocious strain was 85.8% of virulent strain.Precocious strain had less effect on weight gain,and all relative weight gain rates were greater than 90% when inoculated doses were below 2.40×104 oocyst per chicken.Intestinal lesion scores of precocious strain were significantly lower than that of virulent strain (P <0.05).The pathoge-nicity of the precocious strains was attenuated significantly.关键词
