Penelitian ini bertujuan mengetahui pengaruh pemberian antiserum inhibin terhadap kinerja reproduksi kambing lokal. Dalam penelitian ini digunakan 12 ekor kambing betina lokal yang dibagi dalam 2 kelompok, kelompok kontrol dan perlakuan (KI dan KII), masing-masing terdiri atas 5 dan 7 ekor kambing. Seluruh kambing diinjeksi dengan 0,5 ml PGF2α (LutalyzeTM) secara intramuskulus, 2 kali injeksi dengan interval 10 hari. Pada kelompok perlakuan (KII), kambing diinjeksi dengan 500 μg antiserum inhibin pada hari ke-9 siklus dan diikuti penyuntikan 0,5 ml PGF2α 48 jam kemudian. Inseminasi dilakukan 10 jam setelah awal berahi dan diulang 12 jam kemudian. Parameter yang diamati adalah persentase berahi, kebuntingan, kelahiran, kelahiran kembar, jumlah anak total, dan jumlah anak per kelahiran. Hasil penelitian menunjukkan semua kambing (100%) pada kedua kelompok memperlihatkan berahi. Persentase kebuntingan pada KI dan KII masing-masing adalah 60,0 dan 57,1%. Angka kelahiran KI dan KII masing-masing adalah 100% dan persentase kelahiran kembar masing-masing adalah 0,0 dan 50,0%. Total jumlah anak pada KI dan KII masing-masing adalah 3 dan 6, dan rata-rata jumlah anak per kelahiran masing-masing adalah 1,0 dan 1,5 ekor. Perlakuan dengan antiserum inhibin dapat meningkatkan kinerja reproduksi kambing lokal.

The objective of this study was to identify the type of specific glycoconjugates and its distribution in testicular spermatogenic cells in muntjak (Muntiacus muntjak muntjak) based on lectins histochemistry. An adult male muntjak aged 4-5 years old in hard antler period was used in this study. Testicular tissue was fixed in Bouin solution and processed histologically. Histochemistry method was performed using six types biotinylated lectins such as peanut agglutinin (PNA), soybean agglutinin (SBA), wheat germ agglutinin (WGA), ricinus communis agglutinin (RCA), concanavalin A (Con A), and ulex europaeus agglutinin I (UEA I) with 20 µg/ml of concentration for PNA lectins and 15µg/ml for other type of lectins. The results showed that glycoconjugates were detected by all type of lectins except UEA I in testicular spermatogenic cells with variation in distribution pattern and also the intensity of lectins binding. Glycoconjugates β-galactose, β-glucose, mannose, Nacetylgalactosamine, N-acetylglucosamine and sialic acid were stained intensely by lectins in golgy-cap phase and acrosomal phase of spermatids. Glycoconjugate N-acetylgalactosamine was the sugar residues which distributed abundantly that marked by positive reaction with PNA, SBA, and RCA lectins. In conclusion, glycoconjugates are detected in testicular spermatids cells of muntjak indicated that glycoconjugates have an important role in spermatogenesis particularly in spermiogenesis. Key words: glycoconjugates, lectins, spermatid, spermatozoa, muntjak

This study was aimed to determine the effect of epididymis extract (EE) on the testosterone and dihydrotestosterone (DHT) level of local male goat. An experimental study was performed using a completely randomized design (CRD) pattern of one-way analysis of variance (ANOVA). 15 local male goats aged 1.5 years with body weight 14-16 kg were used in this study. The K0 group as a control group, injected with only 1 ml physiological saline, while each KP1, KP2, KP3, and KP4 groups treated with multilevel EE dose, ie 1, 2, 3, and 4 ml / goat for 13 consecutive days. At the end of treatment (day 14th), testes, epididymis (caput, corpus, and cauda) and ductus deferens samples were taken through the close-castration method for examining the testosterone and DHT concentration by using enzyme-linked immunosorbent assay (ELISA) technique. Data gathered were later analyzed using ANOVA followed by Tukey’s HSD in SPSS 16.0 for Windows. The result showed that the average concentration of testosterone on K0, KP1, KP2, KP3, and KP 4 in testis respectively were 10.00±2.64 ng/ml; 7.66±2.51 ng/ml; 10.00±6.55 ng/ml; 0.66±0.57 ng/ml; 11.66±7.37 ng/ml; caput epididymis; 5.00±1.73 ng/ml; 2.33±1.52 ng/ml; 5.00±2.64 ng/ml; 1.33±0.57 ng/ml; 5.66±1.15 ng/ml; corpus epididymis; 1.33±0.57 ng/ml; 0.66±0.57 ng/ml; 4.00±2.64 ng/ml; 0.66±0.57 ng/ml; 4.33±2.30 ng/ml; cauda epididymis: 1.00±0.00 ng/ml; 0.66±0.57 ng/ml; 1.66±0.57 ng/ml; 1.00 ± 0.00 ng/ml; 2.00±1.73 ng/ml; ductus deferens: 3.66±2.51 ng/ml; 0.66±0.57 ng/ml; 3.00±1.00 ng/ml; 1.00±0.00 ng/ml and 3.66±1.15 ng/ml. While the average concentration of DHT on K0, KP1, KP2, KP3, and KP 4 in testis respectively; 10.00±2.64 ng/ml; 7.66±2.51 ng/ml; 10.00±6.55 ng/ml; 0.66±0.57 ng/ml; 11.66±7.37 ng/ml; caput epididymis; 5.00±1.73 ng/ml; 2.33±1.52 ng/ml; 5.00±2.64 ng/ml; 1.33±0.57 ng/ml; 5.66±1.15 ng/ml; corpus epididymis; 1.33±0.57 ng/ml; 0.66±0.57 ng/ml; 4.00±2.64 ng/ml; 0.66±0.57 ng/ml; 4.33±2.30 ng/ml; cauda epididymis: 1.00±0.00 ng/ml; 0.66±0.57 ng/ml; 1.66±0.57 ng/ml; 1.00 ± 0.00 ng/ml; 2.00±1.73 ng/ml; ductus deferens: 3.66±2.51 ng/ml; 0.66±0.57 ng/ml; 3.00±1.00 ng/ml; 1.00±0.00 ng/ml and 3.66±1.15 ng/ml.

This study aims to determine the success of pseudopregnancy induction with artificial copulation methods in local rabbits. In this study, 9 local female rabbits and 1 local male rabbit aged 1–1.5 years-old and 1.8–2.2 kg body weight were used, which were divided into three treatment groups (n= 3). The rabbit in group K1 (negative control) were injected with 0.1 mL of physiological NaCl and were not mated. The rabbits in K2 were induced with artificial copulation by inserting a cotton bud of 1 cm into vagina at five o'clock in the morning, while the rabbits in K3 (positive control) received injection of 100 IU PMSG intramuscularly and mated with males three days post injection and then followed by injection of 75 IU hCG intravenously. The number and size of follicles and corpus luteum were determined by histological examination with HE staining. The number of follicles in the K1 group; K2; and K3 were 5.9 ± 1.45; 0.63 ± 0.35; and 2.06 ± 1.50, respectively (P <0.05). There was no ovulation observed at rabbit in K1 but all rabbits ovulated successfully in K2 and K3. The number of CL (4.83 ± 2.65 and 7.63 ± 0.57) and the size of CL (0.68 ± 0.20 and 1.38 ± 0.16 mm) were significantly difference (P <0.05) in groups K2 and K3, respectively. It was concluded that artificial copulation could induce pseudopregnancy in local rabbits.

Penelitian ini bertujuan mengetahui pengaruh induksi superovulasi dengan pregnant mare’s serum gonadothropin (PMSG) dan follicle stimulating hormone (FSH) terhadap peningkatan level steroid sapi aceh. Penelitian ini menggunakan 6 ekor sapi aceh betina dengan status tidak bunting, minimal 2 bulan pasca partus, sudah pernah beranak, dan sehat secara klinis. Sapi dibagi atas dua kelompok, masing-masing 3 ekor untuk tiap kelompok. Pada kelompok I, sapi diinjeksi dengan 1.500 IU PMSG pada hari ke-9 yang diikuti dengan penyuntikan 5 ml prostaglandin pada hari ke-11. Pada kelompok II, hari ke-9 sampai hari ke-12, sapi diinjeksi dengan FSH dua kali sehari (pagi dan sore, 08.00 dan 16.00 WIB) menggunakan dosis bertingkat yakni 3-3, 2-2, 1-1, dan 0,5-0,5 ml. Pada hari ke-11 sapi diinjeksi dengan 2,5 ml prostaglandin (pagi dan sore, 08.00 dan 16.00 WIB). Koleksi darah untuk pemeriksaan estrogen dilakukan ketika sapi memperlihatkan gejala berahi (saat inseminasi) setelah pemberian PMSG dan FSH yang diikuti dengan pemberian prostaglandin (berahi sesudah superovulasi) sedangkan koleksi darah untuk pemeriksaan konsentrasi progesteron dilakukan pada hari ke-7 setelah inseminasi. Pengukuran konsentrasi estrogen dan progesteron dilakukan dengan metode enzymelinkedimmunosorbanassay (ELISA). Konsentrasi estrogen pada saat estrus setelah induksi superovulasi dengan PMSG dan FSH masing-masing adalah 89,46±2,46 dan 54,62+9,91 pg/ml sedangkan konsentrasi progesteron pada hari ke-7 setelah inseminasi masing-masing adalah 14,78±2,33 dan 17,40±5,8 ng/ml. Hormon PMSG mempunyai kemampuan yang lebih baik dalam meningkatkan konsentrasi estrogen pada saat berahi tetapi hormon FSH mempunyai kemampuan yang lebih baik dibandingkan dengan hormon PMSG dalam meningkatkan konsentrasi progesteron hari ke-7 setelah inseminasi.

This study aimed to determine the effect of prostaglandin F2α (PGF2α) administration on improving semen quality and testosterone levels on Bali cattle. This study used 3 Bali cattle aged 2, 3.5, and 5 years old. The sample used in this study was Bali cattle semen. In this study, the Latin Square Design was used with three different treatments were administered over three time periods. The treatments performed were P1 (5 mL physiological NaCl), P2 (25 mg prostaglandin), and P3 (37.5 mg prostaglandin) while treatment period was three weeks of treatment administration, which were 1st. 2nd, and 3rd week. Blood collected through coccygea vein 30 minutes after treatment to measure testosterone levels using enzyme-linked immunosorbent assay (ELISA) technique. Statistical analysis showed that PGF2α administration at a dose of 25 mg and PGF2α at a dose of 37.5 mg had no effect (P0.05) on volume, color, pH, consistency, concentration, and motility of Bali cattle spermatozoa. The volume of semen obtained from P1; P2; and P3 were 6.5±0.9; 6.3±0.6; and 6.2±1.2 mL, respectively. The color of the semen in P1, P2, and P3 were beige and milky white. The pH in groups P1; P2; and P3 were 6.7±0.6; 7.1±0.2; and 6.5±0.2, respectively. Spermatozoa concentration in P1; P2; and P3 were 1,328±96.43 x 106 cells/mL; 1,354±102.19 x 106 cells/mL; and 1,353.3±88.55 x 106 cells/mL, respectively. Spermatozoa motility in P1; P2; and P3 were 73.3±2.8%; 71.6±2.8%; and 73.3±2.8%, respectively. Testosterone levels in P1 and P3 were 5.05±0.22 and 6.74±1.38 ng/mL, respectively (P0.05). Based on the results of this study, it was concluded that the administration of PGF2α does not affect semen quality but can increase the level of testosterone on Bali cattle.
