RESPON KECEPATAN TIMBILNYA ESTRUS DAN LAMA ESTRUS PADA BERBAGAI PARITAS SAPI PERANAKAN ONGOLE (PO) SETELAH DUA KALI PENYUNTIKAN PROSTAGLANDIN F2Α (PGF2Α)
ABSTRACT: The research aimed
to: (1) determine the response of estrous onset of Ongole Offspring at
thevarious parities after the injection of prostaglandin F2α (PGF2α) twice; (2)
determine the responseof estrous duration of Ongole Offspring at the various
parities after the injection of prostaglandinF2α (PGF2α) twice. The research
was held in November until December 2012, located in PunggurDistrict, Central
Lampung Regency, Lampung Province. This research used CompletelyRandomized
Design (CRD) with three treatments and four replications. The treatments wereOngole
Offspring heifers (P0); Ongole Offspring which have calved once (P1); and
OngoleOffspring which have calved twice (P2). The variables observed was
performed statistically byanalysis of variance on level of 5% or 1%. The result
of the research showed that parity was notsignificantly different (P>0,05)
on the estrous onset and the estrous duration of Ongole Offspringat the various
parities after prostaglandin F2α (PGF2α) injection twice. The estrous onset
ofOngole Offspring at the various parities after the injection of prostaglandin
F2α (PGF2α) twice P0,P1, P2 in a row were 45,57; 43,26; 52,53 hours, whereas
the estrous duration of Ongole OffspringPO P0, P1, P2 in a row were 13,58;
18,65; 15,72 hours.
