Abstract

Development of buffalo was relatively slow in the last five years (1993-1997), but the number of slaughtered animals was also increased in the same period. Factors limiting their development were extensive farming system, farming as a secondary enterprise, slow growth and low reproductive efficiency of the animals. Optimization of artificial insemination (AI) program in one of the alternative to improve buffalo productivity in Indonesia. AI is an effective tool toimprove the genetic quality and to increase the buffaloes population. Application of AI in buffalo has been conducted since 1975, but until now the results are not still significant. Within the last four years the calving average was 750 head/year, the implementation of targeted insemination doses reached less than 50%/year with S/C still above 2 and CR 38.32%. The limiting factors affecting this low performance are quality of semen, female fertility, skill of technician and zootechnical knowledge of farmers. Improvement of reproductive efficiency of buffaloes interrelated with optimization of AI program could be imposed through increasing of ability of farmers to detect oestrus, oestrus synchronization using hormones (PGF-2α and progesterone), improvement of quality of frozen semen with special attention on dilution materials used, control of equilibration time, and control of duration and temperature of thawing, as well as accuracy of insemination time.   Key words: AI, buffalo, semen quality, optimization, oestrus synchronization

Abstract

Semen of two healthy swamp buffalo bulls were collected twice a week using artificial vagina. After initial evaluation, semen was divided into two parts, 1/3 for control (PK) and 2/3 for treatment (PS) and centrifugated at 3,000 rpm for 20 minutes. Seminal plasma of the second part was removed and changed with bovine seminal plasma for 0 minute (PS0) and 5 minutes (PS5) before semen was diluted with lactose extender containing 7% glycerol. Mean percentage of motility after thawing for PS5 (55.71%) was significantly higher (P<0.01) than PK (41.43%), but not significantly different with PS0 (52.43%). PS0 was significantly higher than PK. Mean percentage of live sperm and intact plasma membrane for PS5 (63.43% and 64.71%) were significantly higher (P<0.01) than PK (55.71% and 53.57%), but not significantly different with PS0 (61.14% and 59.28%). There was no significantly difference between PS0 and PK for mean percentage of live sperm and intact plasma membrane parameters. Mean percentage of intact acrosomal for PS5 (53.57%) was significantly higher (P<0.01) than PS0 (48.14%) and PK (43.14%). PS0 was significantly higher (P<0.01) than PK. Under conditions of these experiment it may be concluded that replacement of buffalo seminal plasma with bovine seminal plasma and diluted with lactose extender could improve of frozen semen quality of swamp buffaloes.   Key words : Cattle seminal plasma, frozen semen, swamp buffalo

Abstract

Bucks semen is easily damaged during freezing process, due to the formation of ice crystals. Consequently, semen quality decreases particularly the post-thaw sperm motility, viability, intack plasma membrane and intack acrosomal cap. The objectives of this research are to determine the optimum dose of glycerol in Tris extender in maintaining frozen semen quality of crossbred Etawah bucks. Four head of PE buck of 2 - 4 years old were used in this experiment. Doses of glycerol used were 5%, 6% and 7%. Semen was collected once a week using artificial vagina. Results of this experiment indicated that the mean percentage of pre-freezing motility, live sperm, sperm with intact plasma membrane and intact acrosomal cap in 5%, 6% and 7% glycerol were not significantly different (P>0.05). After freezing, the mean percentage of motility, live sperm, sperm with intact plasma membrane and intact acrosomal cap in 6% glycerol (52.60%, 65.03%, 45.63% and 47.54% respectively) were significantly higher (P<0.05) than in 5% (44.31%, 52.00%, 37.60% and 37.00% respectively) and in 7% glycerol (45.28%, 52.10%, 37.97% and 37.14% respectively). However, there were not significant differences in 5% and 7% glycerol for any parameter measured. It was concluded that supplementation of glycerol 6% in Tris extender effective to protect of sperm from various shock during the process of semen cryopreservation, so that it could maintain of frozen semen quality (sperm motility, viability, intack plasma membrane and intack acrosomal cap) that suitable used in AI program of crossbred Etawah bucks.   Key words : Glycerol, PE bucks, semen quality

Abstract

This study aimed to improve reproductive condition of postpartum anestrus of Etawa crossbreed (PE) goats using PGF2 hormone or progesterone (controlled internal drug release/CIDR-G) and improve pregnancy success from artificial insemination (AI) with human chorionic gonadotrophin (hCG) hormone administration. Administration of progesterone increased estrus by 100%, which was higher than the 70% produced from prostaglandin F2 alfa (PGF2) administration. Estrus onset in CIDR group (35.8013.33 hours) was faster than PGF2 group (45.69.2 hours). Clinical signs of vulva (redness and swollen) were more intense in CIDR-G group (80% and 70%, respectively) compared to PGF2 group (70% and 57%, respectively). Estrus duration in PGF2 group (52.173.34 hours) was longer than CIDR-G group (49.613.56 hours). Pregnancy success in group given hCG was 66.7% while in non-hCG group was 50%. In conclusion, CIDR-G and PGF2 administration is effective to induce estrus of postpartum anestrus PE goats. Administration of hCG at the onset of estrus is effective to improve pregnancy success.
