Abstract:
The aim of this study was to determine the influence of some environmental factors on pregnancy length and time of foaling in purebred Arabian mares raised at the national Haras of Chawchawa in Tiaret Algeria. 1262 breeding records from 1985 to 2010 were analyzed and every hour of birth was noted from 2003 to 2010. The mean gestation length, for all years was 332.85±19.81 days. Effect of foal sex, breeding month, breeding age and breeding year was significant (p<0.005). The gestation lasted a little bit longer 333.71±8.39 days in mares having had colts, than with the mares having had fillies 332.19±8.68 days. We also noted a significant effect of mares and years on the hour of birth (p<0.005). It was noted that 76.19% of foalings occurred between 7 to 19 h. The lowest gestation duration was found 319.75±3.30 days in December and 329.08±7.33 days in January. It was noted that gestation duration increase in other months of birth. Ratios of estrus, pregnancy, sterility, parturition and abortion were 82.51, 62.32, 37.68, 59.77 and 2.55% for Arabian mares, respectively. The results of this study were similar to those described for Arabian mares and other mares’ breeds reported in literature.
