Abstract

This study was carried out to evaluate oestrus responses using double treatments of pgf_2a (Lutalyse and Synchromate) in Nigerian jennies. Eight (8) cycling jennies aged 3.8 ± 2.0 years were used for this study. The jennies were randomly assigned to 2 groups of 4 jennies each; Group 1 (n=4): jennies treated with a double injection of 10mg of Lutalyse; Group 2 (n=4): jennies treated with double injection of 375μg of Synchroniate. Blood was collected from the jennies for extraction of serum, for progesterone and oestradiol estimation using Enzyme-Linked Immunosorbent Assays (ELISA). Groups 1 and 2, had time to onset of oestrus of 3.98 ± 0.95 and 1.78 ± 0.29 hours (P>0.05), duration of oestrus of 78.0 ± 22.7 and 120 16.97 hours (P<0.05), oestrus response rate of 75 and 100% and intensity of synchronization within 48 hours was 75 and 100% (P<0.01), respectively. From this study it was established that the oestrus period and oestrus cycle length of groups 1 and 2 was 8 and 15 days and also 17 and 21 days, respectively, in Nigerian indigenous jennies. In conclusion, Synchronization of jennies is possible using exogenous PGF_2a, however, double treatment of Cloprostenol Sodium (Synchromate) had a better response, therefore, it is more efficient than double treatment of Dinoprost tromethamine (Lutalyse) in oestrus synchronization of jennies.
