A Comparative Study of Respiratory Phagocytic Cell Activities in Layer ChicksMuhammad J. Arshad, Muhammad Siddique, S. U. Rehman, M. Sohail AslamFrom Department of Vet. Microbiology, University of Agriculture, Faisalabad, Pakistan.A comparative study of avian respiratory phagocytes (ARPs) was conducted in four different strains of commercial layer chicks. The birds were raised to 12-14 weeks of age and were used as source of ARPs. Respiratory phagocytic cells harvested 42 hours post-inoculation of 3% Sephadex G-50 into the abdominal air-sacs were assayed for their viability, substrate adherence potential and percentage of macrophages in ARPs. The mean percentage values of viable cells after Sephadex G-50 stimulation were higher in groups B and D compared to groups A and C. Group D showed the maximum while group A the lowest value of substrate adherence potential of ARPs. Group B produced the maximum percentage of macrophages in ARPs. The results of present study suggest that different genetic strains vary in their phagocytic cell characteristics. Keywords: Phagocytic cells, respiratory macrophages, Sephadex G-50Muhammad J.
