Özet
The aim of this study was to investigate the effect of PRID and GnRH combination on fertility parameters of heifers having inactive and active ovaries. Twenty-four heifers (Group I, inactive ovaries n:12 and Group II, active ovaries n: 12) was to used as material of the study. All heifers were inserted PRID (1.55 g progesterone and 10 mg estradiol benzoate) intravaginally for 12 days. At the time of PRID removal, GnRH (0.0042 mg buserelin acetate 2.5 ml i.m.) administered. It was found that between the end of the treatment and time of behavioral estrus were 3.22 +/- 0.97 and 2.91 +/- 1.04 days in Group I and II, respectively. The differences between groups were statistically similar (p>0.05). Following removal PRID, the percentage of estrus detection were 75 % and 91.67% for Group I and II, respectively. Pregnancy rates of the first service and the overall pregnancy rates were 33.33% and 55.56% for Group I and 45.45% and 72.73% for Group II. Intervals between the end of administration and conception were 15.2 +/- 18.57 and 13.0 +/- 15.7 days for Group I and II, respectively (p>0.05). As a result, it has been suggested that PRID and GnRH treatments in heifers with inactive and active ovaries were effective on reproductive performance, observation of estrus and regulation of estrus cycle.
