Effects of Necrotic Enteritis, Aflatoxin B1 and Virginiamycin on Growth Performance, Necrotic Enteritis Lesion Scores and Mortality in Young Broilers
Aflatoxin and necrotic enteritis - alone or in combination - impaired broiler performance, according to a new study in the US. The addition of virginiamycin to the feed ameliorated the deleterious effect of the lower level of aflatoxin on weight gain....
Attachment of Avian and Mammalian Influenza Viruses to the Respiratory and Reproductive Tracts of Layer Turkey Hens
Several types of influenza virus attached to the lower reproductive tract of turkey hens, report Ohio State University researchers, leading them to warn of the potential risks of venereal transmission and egg-associated flu virus spread in turkeys....
