Reproductive parameters of dairy goats after receiving two doses of d-cloprostenol at different intervals.
Animal Reproduction Science 2017 June
This study evaluated the efficiency of two d-cloprostenol injections at different intervals on the reproductive parameters of dairy goats. Trial 1 comprised 54 goats allocated to receive two 37.5μg d-cloprostenol doses at intervals of seven (T7 , n=19), 10 (T10 , n=18), and 11.5 (T11.5 , n=17) days. Trial 2 comprised 62 goats allocated to receive injections at T7 (n=30) and T11.5 (n=32). Ultrasonography was done and blood was collected just before d-cloprostenol injections. After the second dose, goats were artificially inseminated (AI) with frozen-thawed semen at 18-24h (Trial 1) or at 10-24h (adjusted according to the time of estrus onset in Trial 2) after estrus detection. Estrus response rate did not differ (P>0.05) among groups in Trials 1 (T7 =94.7%; T10= 88.9%; T11.5 =88.2%) and 2 (T7 =90.0%; T11.5 =96.9). All females showed progesterone concentrations >1ng/mL before both d-cloprostenol injections. The largest follicle diameter present on ovaries was similar (P>0.05) among treatments at the first and second dose. The second largest follicle diameter was superior (P<0.05) to T7 than to T10 and T11.5 goats at first dose only. This possibly resulted in lower interval to estrus (P<0.05) in T7 -treated goats than other treated goats in both trials. The conception rate was similar among treatment groups in Trials 1 (T7 =55.6%; T10 =18.8%; T11.5 =26.7%) and 2 (T7 =85.2%; T11.5 =93.6%). The three treatments efficiently synchronized estrus. T7 and T11.5 protocols resulted in high estrus synchrony and conception rates when adjusting the AI time according to interval of estrus.
