Artificial insemination (AI) program in swamp buffalo will be more efficient by implementing synchronization of estrus and ovulation. By synchronizing of ovulation, AI can be done at a fixed time schedule without concerning to estrus detection. Gonadotropin Releasing Hormone (GnRH) and human chorionic gonadotropin (hCG) have been used in protocols of estrus synchronization to induce ovulation. A study of AI in swamp buffalo was conducted on 83 buffaloes to evaluate the impact of protocol of estrus synchronization on reproductive efficiency of swamp buffalo. The three protocols used were Ovsynch (GnRH-PGF2Î±-GnRH-AI), convensional (PGF2a-PGF2a-AI) and Select-Synch (GnRH-PGF2a-AI). Inducing of ovulation were done by administration of GnRH or hCG after prostaglandin (PGF2Î±) injection. AI was done at 18 and 24 hour after the second GnRH injection (66 hours and 72 hours after PGF2Î± injection) for Ovsynch method and 72 hours after the last PGF2Î± injection for convensional and Select-Synch methods. Parameters observed were percentage of estrus and pregnancy from the three estrus synchronization protocols and the differences were analysed by statistics. All of buffaloes (100%) in the three synchronization protocols showed estrus behavior prior to AI. The percentage of pregnancy was 64.71; 77.14 and 83.87% for the Ovsynch, convensional and Select-synch respectively and there was no significantly different (P > 0.05) among the three protocols. hCG administration after the last PGF2Î± also did not affect pregnancy rate, ie: 76.47 vs 77.78% (with hCG vs without hCG) for the convensional and 88.24 vs 78.57% for the Select-Synch. It is concluded that the synchronization of estrus protocols in this study can synchronize the estrous and ovulation and AI can be done in a fixed-timed and could reach better pregnancy rate of swamp buffalo.

The aim of the study was to investigate the effect on viability of frozen swamp buffalo semen of glutathione and bovine seminal plasma in lactose extender. Semen from two swamp buffalo bulls was collected twice weekly using an artificial vagina. Pooled, good-quality fresh semen was divided into three parts and centrifuged at 3,000 rpm for 15 minutes in preparation for three treatments-substitution of buffalo seminal plasma with zero, 50 or 100% bovine seminal plasma (BS0, BS50 and BS100, respectively). Each semen aliquot was then divided in two parts, on which was diluted with lactose extender containing 1 mM glutathione (GSH) and the other diluted with lactose extender without GSH (0 mM GSH). Extended semen from all six treatments was cooled to 5oC and then frozen in 0.25 ml straws.Â Mean motility percentages 0 and 30 minutes post thaw (PTM 0â² and 30â²) with GSH were 38.33 and 34.29%, significantly higher (P < 0.05) than treatments without GSH (31.67 and 25.95%). PTM 0â² and 30â² were also higher (P < 0.05) with no substitution of bovine seminal plasma (BS0) than when buffalo seminal plasma was replaced with bovine seminal plasma at either 50 or 100%. Averages were 40.00 vs 34.46 and 30.54% (BS0 vs BS50 and BS100) at thawing and 36.96 vs 28.36 and 25.36% 30 minutes post-thaw. Mean percentages of live sperm (LD), intact plasma membrane (MPU) and intact acrosomal membrane (TAU) at thawing were not significantly different with or without addition of GSH. However,at 30â² post thawing, TAU and MPU were significantly higher in GSH treatments than inthose without GSH:Â 61.50 vs. 58.19% (MPU) and 59.81 vs. 57.38% (TAU). Mean percentages of LD, TAU and MPU 30â²post thawing were higher with no substitution ofbuffalo seminal plasma (BS0) (P < 0.05) than to BS50 and BS100 treatments. In conclusion, the addition of glutathione (GSH) improved the quality of frozen swamp buffalo semen, but the partial substitution of buffalo seminal plasma with bovine seminal plasmaprovided no beneficial effects.

Semen used for artificial insemination (AI) can be prepared in different ways, fresh extended fresh or chilled, or frozen-thawed (FT). The aim of the experiment was to evaluate the use of preserved semen to inseminate the oestrus mares. Nineteen mares were used in this research. The mares were synchronized with double injection of PGF2? 14 days apart. The follicle size was monitored using ultrasound scanner during the third day of oestrus, and 2500 IU hCG was administered at the same time. The AI was conducted 35 hours after hCG injection with total motile sperm 200x106 for chilled semen and 250-300x106 for frozen semen. The result demonstrated that the response of the oestrus with double injection of PGF2? was 73.7%. The conception rate (CR) was 14.3% (1/7) with frozen semen and 42.9% (3/7) with chilled semen. It is concluded that AI with chilled semen resulted higher conception rate than frozen semen.Key words: mare, synchronization, oestrus, ovulation, artificial insemination dose, conception rate

PO cattle have weaknesses to show clear estrus signs which cause difficulty in artificial insemination implementation. The present study was designed to obtain ovarian dynamic as effect of GnRH injection in ovsynch protocol based on progesterone intravaginal device. Heifers (18) and cows (n= 12) were allocated to one of three groups. Cuemate-PGF2α (CP) group inserted with a Cuemate on day 0-7 and injected with prostaglandin on day 7. Cuemate-PGF2α-GnRH (CPG) group was treated as CP group with the addition of GnRH injection on day 9. GnRH-Cuemate-PGF2α-GnRH (GCPG) group was treated as CPG group with addition of GnRH injection on day 0. Ultrasonography was performed on days 0-3, day 7 until ovulation and 7 days after ovulation. Percentage of ovulation synchronization increased significantly (P<0.01) between CP, CPG, and GCPG, respectively, both in heifers (16%, 50%, and 85%, respectively) and cows (0%, 60%, and 100%, respectively), on day 11. Preovulatory follicle diameters between CP, CPG, and GCPG treatments were not different significantly both in heifers (11.9±0.5, 11.9±0.5, and 12.1±0.6 mm, respectively) and cows (11.7±0.4, 11.8±0.7, and 11.1±0.6 mm, respectively). This study concluded that GCPG protocol increased the synchrony of ovulation rate both in cows and heifers, without affecting the follicle preovulatory and CL diameters.Key words: ovarian dynamic, GnRH, ovsych, PO Cattle

Penelitian ini bertujuan untuk mengetahui perkembangan folikel sapi PO dara yang distimulasi menggunakan PMSG dosis rendah (dosis non-superovulasi) dan perolehan folikel dominan pre-ovulatori sebagai informasi dasar untuk penerapan intrauterine programming pada sapi. Sapi PO dara berjumlah sembilan ekor dibagi ke dalam tiga kelompok dosis PMSG yaitu kontrol (NaCl 0.9% sebagai placebo), dosis PMSG 0.5, dan 1.0 IU/kg BB. Injeksi PMSG dilakukan pada awal gelombang folikel ke-2 berdasarkan perubahan dinamika ovari yang dikonfirmasi menggunakan USG diikuti injeksi PGF2α 48 jam kemudian. Perkembangan folikel sejak injeksi PMSG hingga terbentuknya pre-ovulatori folikel (POF) diamati dan dipetakan menggunakan USG. Jumlah POF tertinggi terdapat pada dosis PMSG 1.0 IU/kg BB (4.67+1.67) secara signifikan (P<0.05), sedangkan POF yang terbentuk pada dosis PMSG 0.5 IU/kg BB berjumlah satu, sama dengan kelompok kontrol (P>0.05). Meskipun jumlah POF yang terbentuk berjumlah satu, namun rataan diameter dan volume kelompok sapi dosis 0.5 IU/kg BB lebih besar 16.13% dan 57.14% secara berurutan dibandingkan kelompok kontrol, diikuti oleh dosis 1.0 IU/kg BB dengan nilai tertinggi secara signifikan (P<0.05). Berdasarkan hasil tersebut dapat diketahui bahwa PMSG 0.5 IU/kg BB dapat terkontrol sehingga dapat digunakan sebagai metode pendekatan intrautering programming pada hewan monotokus.

Superovulation treatment on PO cattle (Bos indicus) was less responsive compared to Bos taurus breed. It might due to the difference of their follicular dynamic. This study was conducted to investigate the follicular dynamics and its repeatability in PO cattle. Follicular dynamics observations conducted on 9 cows trough ultrasound scanning every day. Observations of wave patterns repeatability were performed in 6 cows which its wave pattern already known on the next consecutive IOI. Research result indicated that PO cattle had 3 (66%) and 4-waves (34%) pattern. The first wave of 3 and 4-waves pattern emerged on day -0.4+0.9 and 1.4+1.1 respectively. The second wave of 3 and 4-wave pattern emerged on day 9.8+1.5 and 7.4+1.9 respectively. The pattern of 3 waves has a longer follicle dominant duration (11.6+1.5 day) in the first wave of estrous cycle, compared with 4 waves pattern (10+2.92 and 7+1.00 day respectively). The growth rate of dominant follicle was not different significantly between the 3 and 4-waves pattern (0.87+0.23 and 0.94+0.25 mm/day respectively). Similarly, ovulatory follicle diameter between 3 and 4-waves pattern was also not different significantly (12.24+12.34 and 12.30+12.23 mm respectively). Observation of wave patterns repeatability in 6 PO cows indicated that PO cattle had high repeatability in follicular wave pattern (0.88) and the number of growing follicle was 0.91. This study resulted data for dynamic of follicular development, wave pattern, its repeatability which be expected to design the protocol of superovulation treatment or other reproduction technologies based on follicular dynamic to improve its result in PO cattle.
