Abstract
This investigation used 5417 records to study some physiological and productive aspects of Egyptian buffaloes herd at Mehallet Moussa Research farm, Animal Production Research Institute, Ministry of Agriculture, Egypt. Means of calf birth weight, weaning weight, age at first calving, calving weight, calving interval and service period were, 35.6 kg, 87.3 kg, 39.9 month, 512.2 kg, 496 and 181 days, respectively. Study of physiological aspects indicated that mean calf birth weight was affected (p < 0.01) by year of birth, season and parity; calf weaning weight was affected (p < 0.01) by year of birth and season; age at 1s^t calving was affected (p < 0.01) by year of birth only; calving weight; calving interval and service period were affected (p < 0.01) by year of birth, season and parity. Productivity study of the same herd indicated that milk production, lactation period and dry period were affected (p < 0.01) by year of birth , season and parity.
