Fertility of goats following synchronization of estrus with prostagland in F2alpha.
Thirty-four mixed breed cyclic does were randomly divided into two groups of 17 each. One group was synchronized for estrus using two i.m. injections of 8 mg PGF2alpha administered 11 days apart. The other group served as controls and was bred at the time of naturally occurring estrus. Both groups were bred by natural service. Ninety-four percent of the treated does came into estrus within a mean (+/- S.E.) of 53 +/- 3 hours after the second injection of 8 mg PGF2alpha. No differences (P > 0.10) in the first service conception rates based on radiography at mid-gestation were observed between the treated and control groups. It was concluded that the use of 8 mg injections of PGF2alpha 11 days apart had no detrimental effects on fertility of goats.
