Penelitian ini bertujuan mengetahui pengaruh penyuntikan pregnant mare serum gonadotropin (PMSG) terhadap peningkatan respons berahi kambing kacang. Sebanyak 20 ekor kambing kacang betina dewasa kelamin dibagi secara acak ke dalam 5 perlakuan dosis penyuntikan PMSG, yaitu 0,0 (K1); 1,0 (K2); 7,5 (K3); 15,0 (K4); dan 20,0 (K5) IU/kg bobot badan dan diulang 4 kali. Hasil penelitian menunjukkan bahwa pada K3, K4, dan K5 terjadi peningkatan jumlah folikel dominan, total diameter folikel dominan, total volume folikel dominan, dan konsentrasi estrogen dalam serum darah (P0,05), serta menunjukkan gejala berahi yang lebih jelas dibandingkan K1. Konsentrasi estrogen dalam serum darah memiliki korelasi positif dengan jumlah folikel dominan, total diameter folikel dominan, total volume folikel dominan, onset berahi, durasi berahi, perubahan vulva menjadi merah, kebengkakan vulva, peningkatan respons betina terhadap pejantan, dan pergerakan ekor pada saat berahiatau fleging berturut-turut sebesar 53,10; 82,60; 48,80; 53,0; 45,50; 39.40; 32,60; 32,60; dan 80,20% dengan pola kuadratik. Dari hasil penelitian disimpulkan bahwa penyuntikan PMSG pada dosis 7,5; 15,0; dan 20,0 IU/kg bobot badan mampu meningkatkan konsentrasi estrogen dan respons berahi kambing kacang.

Penelitian ini dilakukan untuk mengamati sinkronisasi estrus dan menentukan diagnosis kebuntingan dini pada domba garut (n=3) menggunakan ultrasonografi transrektal. Domba disinkronisasi dengan menggunakan PGF pada fase luteal. Onset dan durasi estrus diamati dengan menggunakan jantan pengusik. Kebuntingan 2a ditentukan dengan tampilan isoechogenic yang dikelilingi oleh tampilan hypoechogenic. Rata-rata onset estrus adalah 35±28,7 jam dan rata-rata lama estrus adalah 33±13,6 jam. Kebuntingan dini terdeteksi pada hari ke-22 (22,3±0,6 hari). Perkembangan fetus diikuti dengan peningkatan diameter dan ketebalan uterus. Diameter uterus meningkat dari hari ke-22 (1,8±0,7 cm) hingga hari ke-42 (5,6±1,1 cm), dan tebal uterus meningkat dari hari ke-22 (0,8±0,1 cm) hingga hari ke-42 (2,1±0,5 cm). Plasentom muncul pada kebuntingan hari ke-34 (0,8±0,2 cm) dan menunjukkan pola perkembangan yang terus meningkat secara signifikan sampai hari ke-56 (2,7±0,5 cm; P0,05). Diameter kotiledon hari ke-34 sekitar 0,8±0,2 cm hingga hari ke-56 (2,7±0,5 cm) dan hari ke-77 (3,3±0,4 cm). Dapat disimpulkan bahwa diagnosis positif dari kebuntingan pada domba garut terlihat pada hari ke-12 dan fetus dapat diamati pada hari ke-22.

This research aims to evaluate the protective potency of freeze-dried egg yolk powder on Garut ram sperm during the liquid semen preservation process. Semen with good sperm quality was divided into three groups and diluted using the following Tris diluents: fresh egg yolk-Tris (FEY-Tris), commercial egg yolk powder-Tris (CEY-Tris), and freeze-dried egg yolk powder-Tris (DEY-Tris). Semen that had been diluted was observed every 12 hours until sperm progressive motility was 50%. Sperm quality was tested for progressive motility percentages, viability, intact plasma membrane (IPM), and intact acrosome (IA). Fresh egg yolk had a particle size of 14460.00330.76 nm, with polydispersity index value (PI) and zeta potential (ZP) being 1.000.11 and -9.220.30 mV, respectively. The particle size of commercial egg yolk powder was 877.90168.86 nm with PI value 0.340.04 and ZP-28.71.24 mV. The particle size of freeze-dried egg yolk powder was 1296.0086.73 nm, with PI value 0.700.04 and ZP-34.50.64 mV. Progressive motility percentage showed that DEY-Tris diluent managed to survive to 51.116.06% for 168 hours, compared to FEY-Tris (51.256.74%) which survived for 156 hours, although no longer than CEY-Tris diluent (53.476.33%) which survive for 180 hours (P0.05). Higher sperm motility was also supported by viability percentage, IPM, and IA, which were all higher (P0.05). In conclusion, freeze dried egg yolk powder mixed with Tris buffer was able to maintain sperm quality during the liquid semen preservation process.

This study aimed to determine ultrasound of uterine involution and postpartum ovarian dynamics on Ongole Crossbreed Heifer (PO) associated with postpartum estrus signs. This study used 6 PO cows which were divided into primiparous group and pluripara group. The observation of uterine involution and ovarian dynamics was started from the first day postpartum using ultrasonography (USG) with a linear probe rectally, while the reproductive organs images were recorded every 2 days. The results showed that the time needed for all reproductive organs of 3 primiparous groups to complete the uterine involution after parturition was 37.331.15 days when the diameter of the vagina, cervix uterine, corpus uterine, left cornua, and right cornua uterine were 3.140.00 cm, 2.860.00 cm, 3.200.06 cm, 4.660.01 cm, and 4.660.01 cm, respectively. The time needed for all reproductive organs of 3 pluripara groups to complete uterine involution postpartum was 38.671.15 days with the diameter of the vagina, cervix uterine, corpus uterine, left cornua, and right cornua uterine 3.180.00 cm, 2.700.02 cm, 3.080.02 cm, 4.420.01 cm, and 4.420.01 cm, respectively. The average times of the first and second ovulation of primiparous cattle were 27.671.15 and 47.671.15 days postpartum, whereas in pluripara group was 28.331.15 and 48.331.15 days postpartum. At first ovulation all cows were not accompanied by signs of estrus, while at the second ovulation 2 primiparous cows and 1 pluripara cow showed less obvious signs of estrus, 1 primiparous cow and 1 pluripara cow showed signs of medium estrus, and 1 pluripara cow showed clear estrus signs.

This study aimed to determine the pregnancy percentage of Ongole (PO) breed cattle by estrus synchronization and ovulation synchronization. This study used 22 cattle that were divided into three groups: Estrus synchronized cattle (K1, n= 5); ovulation synchronized heifers using ovsynch (K2, n= 6); and ovulation synchronized cow using ovsynch (K3, n= 11). Parameters measured were diameter of corpus luteum (CL) in estrus synchronization, follicular diameter upon synchronization and artificial insemination (AI), and percentage of pregnant cattle. Data obtained were statistically analyzed using analysis of variance followed by Duncan test. Results showed no significant differences (P0.05) of CL diameter at the time of estrus synchronization in all groups of cattle with an average of 16.633.79 mm. The CL diameter at the time of estrus synchronization was not significantly different among groups, with an average of 8.80 2.07 mm. Diameter of follicles during ovulation synchronization was also not significantly different among groups. The average diameter of follicles was 9.012.05 mm. Diameter of follicles at the time of estrus and ovulation synchronization was not significantly different among groups with an average diameter of follicles of 10.942.10 mm. The pregnancy percentage of K1, K2, and K3 were 60%, 16%, and 36%, respectively. There was no correlation between the diameters of follicles during estrus with the pregnancy percentage. Estrus synchronization produced higher pregnancy rate than ovulation synchronization in cow or heifers.

The present study examines anatomy of Gayo mare reproductive organs. This study used three sample of Gayo mare reproductive organs (n= 3) for observation of morphology and morphometric of the mare reproductive organs. The ovarium was fixed in 4% paraformaldehyde solution then followed by histological method and stained using hematoxylin and eosin (HE) and Massons trichome (MT). Three mares were observed for diameter and changes overview of uterus during estrous cycle in real time using ultrasound. The results showed that, in general, the anatomy of Gayo mares reproductive organs was similar to other mares, but smaller in morphometry. The total length of the Gayo mares reproductive tract from labia to apex cornua was 48.001.00 cm. Weight of Gayo mares left ovary was 19.077.70 g and the right was 24.430.83 g. Histologically, there was no difference between Gayo mares structure and other mares. In cortex uteri there were some follicles surrounded by capillary, various development stages of follicles, healthy follicles, atretic follicle, and corpus albican; while in medulla there were a lot of connective tissues. Ultrasound of the uterus showed the change in diameter during estrous cycle with the largest diameter of corpus uteri was 4.430.10 cm in horses with estrous cycle of 21 days and 6.300.93 cm in horses with 24 days estrous cycle. In conclusion, the morphometry of Gayo mare reproductive organs are smaller than the other horses and there are differences in diameter of the uterus during the estrous cycle due to the changes of endometrium thickness.

Penelitian ini bertujuan mempelajari gambaran ultrasonografi (USG) ovarium kambing kacang setelah penyuntikan hormon prostaglandin. Penelitian ini menggunakan enam ekor kambing kacang berumur 2-3 tahun, pernah melahirkan, dan bersiklus reproduksi normal. Pengamatan ovarium dilakukan dengan menggunakan USG selama 7 hari sebelum penyuntikan hormon prostaglandin sampai dengan ovulasi. Pengamatan ovarium dilakukan setiap hari dan diintensifkan setiap 12 jam menjelang ovulasi. Pengamatan ovarium terdiri atas folikel dan korpus luteum (CL). Pengamatan visualisasi respons berahi dilakukan sebelum dan setelah penyuntikan hormon prostaglandin. Hasil penelitian menunjukkan bahwa ovarium memperlihatkan dinamika folikel dan CL. Dinamika folikel dikarakteristikkan dengan gelombang folikel. Interval antara penyuntikan hormon prostaglandin sampai dengan ovulasi ialah 52,86,6 jam dengan nilai rataan diameter folikel ovulasi 5,70,7 mm. Visualisasi respons berahi pada kambing kacang tidak bermakna baik sebelum dan setelah penyuntikan hormon prostaglandin.
