Material type: materialTypeLabelBookPublisher: 1985Subject(s): Department of Livestock ProductionDDC classification: 0017,T Dissertation note: One hundred and twenty day-old broiler chicks were used in the study. All the birds were brooded uniformally on the floor for the first two weeks. They were then divided randomly into four treatments on the basis of floor space and litter depth, having floor spaces of 750 or 500 sq. cm. /bird and litter depths of 8 or 16 cm. The parameters studied were body weight gain, feed consumption, feed conversion ratio and mortality from 3 to 8 weeks of age. Hemoglobin concentration and differential leukocyte count were also investigated at 21st. 35th and 49th day of the experiment. Dressing percentage and chemical analysis of carcasses of birds were performed at the end of experiment. No significant difference was observed in body weight feed consumption, feed conversion ratio and dressing percentage among the treatments. Mortality and breast blisters were negligible hemoglobin concentration was also non significant among the treatments. A significant difference was observed in Heterophil/Lymphocyte ratio and in number of lymphocytes at 35th day. Heterophil/Lymphocyte ratio was increased while number of lymphocytes decreased by increasing the stock density. Chemical analysis of carcasses of birds also showed non-significant differences among different treatments between the values of protein, fat, ash and moisture.
