| Abstract | ||||
| The objectives of the current study were to: i) Evaluate the effect of environmental factors on productive and reproductive traits of Egyptian buffaloes, ii) Estimate heritability, and correlation among these traits. Data of 1563 dairy records collected from 341 Egyptian buffaloes that were serviced naturally by 71 sires and raised at Mahallet Mousa station in Kafr El-Sheikh governorate, these collected data were analyzed statistically. Records covered the period from 2001 to 2020. The fourth parity recorded the highest calf birth weight (37.41 kg), and maximum lactation length (197.51 day), and yield (1.69 ton). Buffalo cows that calved in winter produce more milk, and have more number of days in milk than other seasons. Calf birth weight showed significant effect on total milk yield with higher birth weight recorded for higher yield. A high heritability estimate (0.64) was reported for lactation length, while moderate heritability estimates were recorded for dam calving weight, calf birth weight and total milk yield (0.26, 0.20 and 0.15 , respectively). While low heritability estimates (0.08) was recorded for CI. It seems that, season, parity, body weight at birth, and dam calving weight could be used as predictors for the improvement of productive and reproductive traits in Egyptian buffalo breeding programs. The results of our study supported the need, not only for genetic selection programs, but also enhancing the managemental practices of rearing farm for improving productive and reproductive traits of Egyptian buffaloes. | ||||
