Days to first heat, days to first service, days open, calving interval, pregnancy rate at first service (PR), and services per conception (SPC) were analyzed with a repeated measures model that included SIRE (except for SPC and PR), BG, CY, CS, and lactation number.
Female traits: Reproductive records, age at first calving, weight at first calving, days to first heat after calving, days to first service after calving, days open, calving interval, number of services per conception, and pregnancy rate at first service were collected and analyzed.
The service period and number of services per conception
(NSC), as well as the incidence of retained fetal membrane (RFM), clinical metritis and mastitis were taken from the computer records.
Average number of services per conception
observed was 2.
The criteria used for this purpose were: 1 = age at first service (year) and number of services per conception = 3 were considered for outliers.
Data on number of services per conception showed significant (P<0.
While service period, conception rate and number of services per conception
were non significantly (p>0.
9 day) and their number of services per conception
was significantly lower (0.
Reproductive performance of the buffaloes in two different seasons of calving was evaluated on the basis of PDD, uterine involution, days to first service, service period, risk to first service on days 60, 90 and >90, pregnancy risk to first service and up to days 60 and 90, and number of services per conception
2006), resulting in increased number of services per conception
Data on 451 records for service period and 405 records for services per conception
of Nili -Ravi buffaloes maintained at Livestock Experiment Station, Bahadurnagar, Okara spanned over a period from 1997 to 2006 were analyzed to examine the effect of year, season of calving and parity number.
Buffaloes fed HB diet had higher conception rate and less services per conception
than those fed 0B diet.
