Prostaglandin f2? is one protocol that is widely used in estrous synchronization
programs for livestock. The aim of this study was to determine the estrous response of
Etawah Crossbred does on estrous synchronization using a 1ml of prostaglandin F2?. 1ml of
prostaglandin F2? (LutalizeTM) with 11 days interval was injected to each of nine selected
Etawah Crossbred does aged above 3-year-old, with parity more than twice, and did not
pregnant. The goats were individually housed at Faculty of Animal Science of Universitas
Gajah Mada (UGM) with average body weight, BCS, DM intake, and TDN of 41.15±8.31 kg,
3, 685.98±287.52 gr/head/day and 393.33±180.41 gr/head/day, respectively. Estrous
responses observed were changes in vulva size (length and width), pH, color, presence of
mucus, and behavior which was observed before injection (0h) and after the 2nd injection at
12h, 24h, 36h, 48h. Data were analyzed in descriptive quantitative and one-way ANOVA
followed by DMRT. Changes in vulva length did not differ, but the width and pH vulva were
significantly different (P <0.05) at 0h, 12h with 24h, 36h and 48 h. The pattern was similar to
that which occurred in vulva discoloration, the presence of mucus and behavioral changes
whose scoring values tended to increase at 12h, 24h, 36h and 48h after 2nd injection, except
for the vulva color which decreased in the 48h.. It can be concluded that the injection of 1ml
of prostaglandin F2? with 11d interval could cause estrous in Etawah crossbred does after
24h. |
