Abstract


Regression analyses to explore the relationships between age growth and feed consumption in Japanese quails (Coturnix coturnix japonica) hatched during monsoon (August) and winter (November) and maintained at Poultry Research Division (now CARIB, Indian Veterinary Research Institute, Izatnagar, was undertaken. Mean bodyweight and feed consumption data at different ages of totally 200 and 120 birds from monsoon and winter hatches, respectively, were utilized. It was concluded that during first 56 days of life, age significantly influences both growth and feed consumption simultaneously and hence, significant relationship between body weight gain and feed consumption was thought to be fortuitous. During first 56 days of age almost all the growth was over and during this period birds hatched during monsoon season required less amount of feed to gain 100 g body weight than those hatched during winter. During 56th to 120th day of age there was little or no increments in body weight and hence partial regression coefficients due to effects of age and feed consumption of body weights were insignificant.
