Abstract

Bottlenose dolphins were often found in zoos and aquariums. Dolphin calves have a higher mortality rate in the first month after birth as they are unable to eat and breathe properly. The inability to thrive can affect growth until adulthood. This research was being conducted to better understand the nursing and breathing patterns of a bottlenose dolphin calf. Data were collected by observing the behaviour of a post-partum dolphin calf for 24 hours over 3 months (90 days). The behaviours observed were the calf's nursing (frequency, daily duration, and duration of suckling) and breathing (frequency). The results showed a decrease in the frequency of suckling and an increase in the duration of suckling, which indicated that the calf was becoming more successful at suckling. A constant decrease in respiratory frequency indicated a healthy growing calf due to an increase in lung capacity. These results indicated that the feeding and respiratory behaviour patterns of normally developing bottlenose dolphin calves showed a decrease in feeding frequency and an increase in feeding duration, as well as a decrease in respiratory frequency per week. Further studies on the feeding and respiratory behaviour of bottlenose dolphin calves.

Abstract

Penelitian ini mengevaluasi efektivitas sinkronisasi estrus menggunakan prostaglandin F2α (PGF2α) pada sapi Bali dan menilai hasil kehamilan setelah perlakuan awal dan resinkronisasi selanjutnya. Sepuluh sapi Bali menerima dua suntikan PGF2α, diberikan dengan jarak 11 hari, sesuai rekomendasi standar. Hewan yang menunjukkan estrus diinseminasi buatan, dan diagnosis kehamilan dilakukan 30–45 hari setelah inseminasi menggunakan ultrasonografi. Sapi yang gagal hamil selama siklus pertama menjalani protokol resinkronisasi dua minggu kemudian. Protokol sinkronisasi menghasilkan respons estrus 100%, dengan tingkat kehamilan awal 40% (4 sapi). Resinkronisasi enam sapi yang tidak hamil menghasilkan dua kehamilan tambahan (33,3%), sehingga menghasilkan tingkat kehamilan keseluruhan 60%. Temuan ini menunjukkan bahwa PGF2α efektif dalam mengatur siklus estrus dan meningkatkan efisiensi reproduksi sapi Bali, terutama bila diintegrasikan dengan strategi resinkronisasi.
