Resumen

The rate of avian leukosis virus (ALV) horizontal transmission from positive newbom to negative newbom broiler chicks in the same flock was studied using 240 broilers (Ross 308 line n= 60 male and 60 female and Cobb Vantress line n=60 male and 60 female). The birds were tagged and housed in sheds (8 birds/m2) at the Faculty of Veterinary Medicine, San Marcos University, Lima. Cloaca! swabs, taken from every bird at one day of age, were tested for ALV using the ELISA p27 test. A total of 9 positives (Ross 308 n=5, Cobb Vantress n=4) were found and housed together with 111 negative birds from both lines. The remaining 120 negative birds, again from both lines, were likewise housed together as a control group. Cloaca) swabs were taken from every bird and ELISA tested at 21, 28 and 49 days of age. The greatest prevalence of ALV infection, 60.18 ± 9.03%, was found at 49 days in the group containing the infected chicks. At 21 days, the accumulated incidence of ALV infection in these birds, 34.62 ± 8.77%, reflects a horizontal transmission rate of 13.57%.
