Total of 1189 records of Egyptian buffaloes at Mehallet Mousa farm belonging to Ministry of Agriculture were used to study the influence of year and season of calving and parity on each of days open, calving interval and dry period were studied. The estimate of the phenotypic and genetic parameters of these traits were also investigated. Least squares analysis of variance showed a highly significant effect of year and season of calving and parity on all traits (P

Study was undertaken to examine lead contents in different feeds and drinking water offered to buffaloes as well as those of buffalo blood and milk during two different seasons (winter and summer) in the area of Dakahlia, Egypt. The study revealed that the feedstuffs and drinking water contained less than the tolerance lead level, although the lead contents of the samples obtained in winter were higher than those of summer. The levels of lead in the blood and milk of buffaloes were within the normal range. However, winter values were higher than summer values. The lead contents of blood of veal calves were lower than those of buffalo bulls
