| description | Breeding data were analysed for 398 gestation periods of 117 purebred Ara'b mares aged 4-19 years which were maintained on Sultansuyu State Farm in Turkey from 1980 to 1907.<p>
Mares were bred in March, April and May, and 249 foaling mares were fred at the foal heat (within 8-12 days). Oestrous detection were made by teasing procedure and clinical examination before being mated 'naturally on the 2nd, 4th and 6th days of oestrus. If a mare was not in oestrus during 60 days it was presumed to be pregnant.<p>
The number of mares at foal heat mating, non foal heat mating and maiden mare mating were 249, 204 and 60 and the respective conception rates were 59.04 %, 60.78 % and 65.00 %. In these three groups, after three cestrous matings conception rates were 75.90 %, 79.90 % and 76.67 %, the rates of mares from which the foal was aborted or dead were 2.41 %, 3.43% and 1.67%, the rates of mares failing to conceive were 24.10%, 20,10 % and 23.33 % and the rates of mares producing a live foal were 73.49 %, 76.47% and 75.00 %, respectively.<p>
The grand total conception rate at first oestrous mating was 60.43 %, after three oestrous mating was 77.58 %. Grand total rates of mares from which the foal was aborted or dead, mares failing to conceive and mares producing a live "foal were 2.78 %, 212.42 % and 74.85 %, for all eight years, respectively.<p>
Last mating day and birtih day were included to gestation length. Gestation length ranged from 314-372 days and averaged 336.45 + 0.45 days. The average gestation length of 145 mares mating at foal heat, 194 mares mating at non foal heat and 45 maiden mares mating were 33.7.95 ± 0.7/2, 33539 ± 0.64 and 336,16 ± 1.16 days, respectively. The differences between average gestation lengths were significant (P< 0.05). |
