Abstract
This study was conducted in 5 different areas of buffalo aggregations in Baghdad, Al-Fadhalyia, Alma'mil, Abu Ghruib, Al-Taji and Boob Al-Sham during 2012-2013. The study covered 139 vists to buffalo breeder who has 5 to 500 heads. The total final number of animals studied was 9253. This study was contained with some of reproductive traits, like age at first calving, days open and service per conception. They used SAS program for analysing data to study two main effects which were buffalo age (parity) and location on that trait. The highest milk yield was recorded for 3rd and 4th female birth group, the mean was, 6.27 ± 0.14 kg in Al-ma'mil area and lowest was 3.75 ± 0.07 kg in Boob A l-Sham area (P<0.01). The lowest milk yield they found in 2nd group of birth and this was ranged between 3.12 ± 0.05 kg in Al-Taji and 5.95 ± 0.05 kg in, Alma'mil area and these differences were highly significant. The lowest age at first calving were in Al-Fadhalyia area (26.75 ± 2.46 months) compared with the highest age in Alma'mil area (34.20 ± 2.19 months) and these differences were highly significant (P<0.01). And the lowest service per conception was in Al-Tagi area compared to highest conception in Abu-Ghruib area (1.73 ± 0.04 and 2.39 ± 0.07) respectively (P<0.01). We concluded that daily dairy production and some reproductine traits differ due to location and flock.
