"Banteng jawa (Bos javanicus javanicus) merupakan spesies yang terancam punah akibat berbagai aktivitas manusia, sehingga perlu dilakukan konservasi secara ex-situ seperti di Taman Margasatwa Ragunan. Masalah baru, yaitu inbreeding, terjadi sehingga dilakukan pertukaran individu banteng jawa berdasarkan rekomendasi Global Species Management Plans (GSMP) untuk mengatasi permasalahan tersebut. Penelitian ini bertujuan untuk menganalisis perilaku reproduksi dan interaksi banteng jawa jantan dan betina yang dipasangkan melalui program GSMP. Subjek penelitian ini adalah satu individu banteng jawa jantan (J1) asal Taman Margasatwa Ragunan, yang dipasangkan dengan satu banteng jawa betina (B1) asal Taman Safari Prigen, serta satu banteng jawa betina (B2) asal Taman Margasatwa Ragunan. Penelitian dilakukan selama dua bulan (Januari—Maret 2024) sebanyak 5 (lima) kali dalam sepekan. Metode penelitian yang digunakan merupakan scan sampling dan ad libitum dengan interval 5 (lima) menit tanpa jeda. Hasil penelitian menunjukkan bahwa persentase perilaku harian tertinggi pada J1 dan B1 merupakan perilaku makan, diikuti dengan perilaku istirahat dan lokomosi. Persentase perilaku sosial positif, seperti approaching dan allogrooming, antara J1 dengan B1 tinggi, tetapi agonistic action juga cukup tinggi. Perilaku sosial yang paling dominan teramati merupakan perilaku approaching yang dilakukan J1 terhadap B1. Perilaku reproduksi berupa sniffing genitalia, licking genitalia, dan flehmen dapat teramati. Persentase perilaku reproduksi antara J1 dengan B1 yang dipasangkan lebih rendah dibandingkan J1 dengan B2, sedangkan perilaku mounting hingga kopulasi tidak teramati.

Javan banteng (Bos javanicus javanicus) is a species that is categorized endangered due to various human activities that lead to the need for ex-situ conservation, such as in Taman Margasatwa Ragunan. Another problem that is inbreeding occurred, then the javan banteng were exchanged based on the recommendations of the Global Species Management Plans (GSMP) to solve this problem. This study aims to analyze the reproductive behavior and interactions of male and female javan banteng that was paired through the GSMP. The subject of this study was a male javan banteng (J1) from Taman Margasatwa Ragunan that was paired with a female javan banteng (B1) from Taman Safari Prigen, and a female javan banteng (B2) from Taman Margasatwa Ragunan. This study was conducted from January to March 2024 for 5 days a week. The research methods used were scan sampling and ad libitum with 5 minutes intervals without pause. The results showed that the highest percentage of daily behavior of J1 and B1 was eating behavior, followed by resting and locomotion behavior. Percentage of positive social behaviors, such as approaching and allogrooming between J1 and B1 was high, but the agonistic actions was also quite high. The most dominant social behavior observed was approaching behavior of J1 towards B1. Reproductive behaviors such as sniffing genitalia, licking genitalia, and flehmen were observed. Reproductive behaviors between J1 and B1, that was paired, are found lower than J1 and B2. Mounting and copulation behavior were not observed."

"Anoa dataran rendah kini berstatus terancam punah sehingga perlu dikonservasi secara ex-situ seperti di Taman Margasatwa Ragunan (TMR). Ditemukannya kasus perkawinan sedarah anoa di TMR mendorong mereka untuk terlibat dalam program collaborative captive breeding antarhabitat ex-situ di bawah pedoman Global Species Management Plan (GSMP) untuk meningkatkan keragaman genetik anoa. Penelitian ini bertujuan menganalisis perilaku sosial dan reproduksi anoa jantan di TMR untuk mengevaluasi kesiapannya sebelum dipasangkan dengan anoa betina hasil pertukaran. Pengamatan terhadap satu ekor anoa jantan dewasa dilakukan selama 2 bulan (Januari—Maret 2024) dengan metode scan sampling dan ad libitum, mencakup 60 sampling point dari 38 hari pengamatan. Hasil menunjukkan variasi aktivitas harian dan kecenderungan berinteraksi secara sosial dan reproduktif oleh anoa jantan, ditandai dengan perilaku approaching, vocalization, dan sniffing (termasuk flehmen) meski terhalang pagar pemisah dengan anoa betina di kandang sebelahnya. Anoa jantan secara keseluruhan menunjukkan ketertarikan dan pendekatan aktif untuk berinteraksi sosial dan reproduksi, sehingga dapat mendukung potensi keberhasilan program breeding.

The lowland anoa is an endangered species which requires ex-situ conservation efforts like those at Taman Margasatwa Ragunan (TMR). Inbreeding cases discovered at TMR prompted their participation in a collaborative captive breeding program guided by the Global Species Management Plan (GSMP) aimed at increasing the genetic diversity of anoa. This study focused on observing the social and reproductive behavior of a male anoa at TMR as part of evaluating his readiness to be paired with an exchange-bred female anoa. The observation of one adult male anoa was conducted for two months (January—March 2024) using scan sampling and ad libitum method, covering 60 sampling points from 38 observation days. The results revealed that male anoa engaged in various daily activities and exhibited a propensity for social and reproductive behaviors, such as approaching, vocalization, and sniffing (including flehmen), despite being separated by fences from a female anoa in the adjacent enclosure. The overall observations suggest that male anoa displayed interest and actively sought social and reproductive interactions, supporting the potential success of the breeding program."
