PENGARUH PARITAS TERHADAP PERSENTASE ESTRUS DAN KEBUNTINGAN PADA SAPI BALI YANG DISINKRONISASI ESTRUS DENGAN DUA KALI PENYUNTIKAN PROSTAGLANDIN F2Α (PGF2Α)
ABSTRACT: The research aimed
to: (1) determine the effect of parities on the precentage of estrous
andconception of Bali cows after estrous synchronization with prostaglandin F2α
(PGF2α) injectiontwice; (2) determine the best parity of Bali cows after
estrous synchronization with prostaglandinF2α (PGF2α) injection twice from the
various parities of Bali cows.The research was held in November until February
2013, located in Sukoharjo II Village,Sukoharjo District, Pringsewu Regency.
This research used Completely Randomized Design(CRD) with three treatments and
four repetitions. The treatments were Bali heifers (P0); Bali cowswhich have
calved once (P1); and Bali cows which have calved twice (P2). Hormone used for
thesynchronization was Juramate® with doses of 500 μg/cow or 2 ml/cow
intramuscularly. Data ofpercentage of estrous and conception was analyzed by
using Chi-square on significant level of 5%.The result of the research showed
that estrous percentages after prostaglandin F2α (PGF2α)injection twice of Bali
Cows P0, P1, P2 were 100%. The conception percentage of Bali cows P0, P1,P2 in
a row were 100%; 75%; 75%. Based on the advanced test of Chi-square, parity was
notsignificantly different (P>0,05) on the percentage of estrous and
conception of Bali cows after theprostaglandin F2α (PGF2α) injection twice.
