Body weight and egg number did not vary significantly in relation to fasting and feeding regimes. Total lipids varied significantly in relation to fasting regimes (P0.01). Total lipid concentration was maximum (1828.2 mg/dl) in birds which had undergone 10 days fasting and minimum in birds that had fasted 15 days (936.3 mg/dl). The cholesterol concentration (82.5 mg/dl) was found to be significantly lower (P0.05) in birds which were fasted for 51 days. Total protein contents were the highest in birds with 10 days fasting and then continuous feeding (6.0 gm/dl). Albumin and globulin concentrations were not significantly different either with the fasting or feeding regime, but globulin content was significantly higher in birds that had had 10 days fasting and continuous feeding (4.0 gm/dl). Glucose concentration was lowest (181.3 mg/dl) in birds having 5 days fasting and continuous feeding. Phosphorus and calcium concentrations were significantly higher (7.4 and 18.5 mg/dl, respectively) in birds subjected to 10 days fasting.
