Daftar Isi:
- The aim of the study was to investigate response, behavior, cycle of estrous and estrogen hormone profile of Bali cattle (Bos sondaicus) which were synchronized by PGF2a. Material samples were 9 Bali cattle at ±3 years old and the average body weight were 313,67±20,66 kg. Bali cattle were synchronized by injection of PGF2a with dosage 5 mg per cattle through intramuscular. Synchronization were covered by two injection with interval 12 days. The bloods were taken before and after injection PGF2a through jugular vein as much as 3 ml per sample. Then bloods samples were analyzed by estrogen hormone kit of Enzyme-Linked Immunosorbent assay (ELISA). The estrous observation was every day. The result showed that response 100% estrus after the post injection PGF2a, onset estrous 57:49±0,55 hours/minutes, estrous indication and behavior were red vulva, mucus, warm, and standing heat, cycle of estrous was 20,11±1,36 days, the concentration of profil estrogen hormones estrus were 35,69±11,83 pg/mL, and non-estrus 25,16±11,92 pg/mL. The study concluded that Bali cattle synchronized using PGF2a showed normal response in onset estrous, behavior and estrous cycle while the concentration estrogen hormones were increased while estrous.
