The timor deer (Cervus timorensis) is deer that natively distributed within Java and Bali, and has been introduced to other regions and other countries. The aim of this study is to observe the daily behavior of timor deer that inhabited Savana Bekol, Baluran National Park. We collected the data of timor deer behavior using continuous focal animal sampling method (Altmann 1974). We collected the daily activity budget data for 12 hours, from 06.00 until 18.00. Results showed that in general females spent most of their activities during the day (from high to low) on feeding, resting, moving, other activities, and vigilance While males spent most of their activities on resting, feeding, moving, other activities, and vigilance.

The response of estrus can be enhanced by providing PGF2α and a combination of PGF2αGnRH so that the time of mating using Artificial Insemination (AI) can be held precisely. This study aims to compare the response of estrus synchronization using PGF2α compare to PGF2α-GnRH. Twenty female cattle Ongole Crossbreds, 4-6 years, BCS average of 3-4 were used in this research. Cattle were selected based on their luteal phase at the days of 7 to 18 by rectal examination. Then, all of the cattle were injected by cloprostenol® with a dose of 500 ug intrauterine. Ten of the animals were injected by 2.5 mL of Fertagyl® intramuscularly after 48 hours then continued observing and response estrus detection. The onset of estrus using PGF2α was detected on 75.94 ± 0.78, while 41.57 ± 28.40 hours for PGF2α-GnRH Using statistical, there was a significant difference (P<0.05). Duration of estrus phase using PGF2α was 24.65 ± 0.49 whereas PGF2α-GnRH was 10.88 ± 7.45 hours. Using statistical methods, there was a significant difference (P <0.05). It could be concluded that the use of PGF2α was more effective for the duration and intensity of estrus, and a combination of PGF2α -GnRH is more effective for stimulating estrus.

Penelitian ini bertujuan mengetahui gugus fungsi penanda yang merepresentasikaan hormon metabolit E1C dan PdG serta bilangan gelombangnya pada urine yang didukung dengan pengamatan genitalia untuk memastikan pendeteksian masa subur pada lutung jawa (Trachypithecus auratus). Sampel urine dan pengamatan genitalia diperoleh dari 2 (dua) ekor lutung jawa betina di Pusat Primata Schmutzer, Kebun Binatang Ragunan, Jakarta. Sampel urin diambil setiap hari dan dilengkapi dengan pengamatan genitalia. Hasil menunjukkan bahwa gugus fungsi penanda yang merepresentasikan E1C dan PdG pada lutung jawa sama dengan yang teridentifikasi pada tikus namun dengan bilangan gelombang berbeda.  Hormon metabolit E1C direpresentasikan melalui gugus fungsi alkil, aromatik, dan hidroksil pada bilangan gelombang 596 cm-1, 698 cm-1, 3599 cm-1, dan PdG direpresentasikan melalui gugus fungsi alkil dan aldehid pada bilangan gelombang 1450 dan 1699 cm-1. Dari penelitian ini dapat disimpulkan bahwa gugus fungsi penanda yang teridentifikasi oleh fourier transform infrared (FTIR) dapat berlaku secara universal, namun bilangan gelombang yang merepresentasikannya bersifat spesifik spesies.

ABSTRAKPenelitian ini bertujuan memperoleh profil fluktuasi kadar hormon ovari sepanjang siklus estrus. Sampel darah yang berasal dari sepuluh ekor tikus betina diambil selama tiga siklus estrus dan dianalisis menggunakan perangkat inframerah. Kadar progesteron selama tiga siklus memiliki kisaran 6-11 ng/ml pada masa estrus dan meningkat menjadi 32-49 ng/ml pada saat non-estrus.Kata kunci: kawin inframerah, progesteron, siklus estrus, tikus betina ABSTRACTThe aim of the study was to obtain hormonal fluctuated profile of ovarian hormones throughout estrous cycle. Blood samples from ten female rats were collected during three consecutive estrous cycles and analyzed by infrared spectroscopy. The absorbance values of functional groups of progesterone were converted to ng/ml ranging between 12. 135-39.387 ng/ml for ketone; 7.995-35.702 ng/ml for metil; and 7.542-39.249 ng/ml for metil ketone. The progesterone level during three cycles ranging between 6-11 ng/ml on estrous cycle and 32-49 ng/ml on non estrous cycle.
