RESPON OVARIUM SAPI LIMOUSIN DAN SIMMENTAL TERHADAP INDUKSI FOLLICLE STIMULATING HORMONE

OVARIUM RESPONSE OF LIMOUSIN COWS AND SIMMENTAL COWS ON  FOLLICLE STIMULATING HORMONE INDUCTION. To assess the effect of FSH administration on ovarian response rates. and to examine the effect of synchronizing follicular waves on ovarian response rates and the acquisition of embryos that are worthy of transfer. This research was carried out at the Laboratory of Embryo Production of Livestock Embryo Hall Cipelang Cijeruk district, Bogor regency, for 30 days. The materials used in this research were 50 cattle consisting of 25 female Limousin cows and 25 Simmental female cows at the aged around 5-7 years. They have given birth, and have been superovulated, at the body condition score (BCS) of 2.5-3.0, at the healthy and given forage and concentrate (BET protocol). FSH used was the Folltropin®-V brand superovulation with a dose of 20 mg / ml, the cement used was in accordance with the type of donor cow, with a concentration of 25 x 106 spermatozoa per straw. Primary data retrieval were done by observing the focal animal sampling technique requiring direct observation in the research location where the research material was located. The variables measured were response rate, number of corpus luteum (CL) in the left and right ovaries, the total collected embryos and ovum. Superovulation using Folltropin®-V in Simmental and Limousin cattle at Cipelang Livestock Embryo gave more significantly effect on Simmental cattle compared to Limousin cattle. Limousin and Simmental cattle supplemented with the hormone Folltropin®-V produced an average number of CL, embryos and ovum in Simmental cattle higher than Limousin cattle superovulated with FSH hormone. They have also a significant effect on the response rate, recovery rate, average CL number and the average number of embryos. The results obtained showed that Limousin and Simmental cattle differences significantly affected the number of collected embryos and ovum, the proportion of transferable embryos, Degenerate (Dg) embryo proportions and unfertilized proportion of Embryo Unfertilized (UF).Keywords: Limousin cows, Simmental cows, Superovulasi, FSHÂ

KARAKTERISTIK SEMEN SEGAR SAPI BANGSA LIMOUSIN DAN SIMMENTAL DI BALAI INSEMINASI BUATAN LEMBANG

FRESH SEMEN CHARACTERISTICS OF LIMOUSIN AND SIMMENTAL BULLS AT THE ARTIFISIAL INSEMINATION CENTER, LEMBANG. This study was conducted to evaluate the characteristics of fresh semen in Limousin and Simmental bulls at the artificial insemination center in Lembang. Results of this study showed that ejaculation frequency of Simmental bull was significantly higher than that of Limousin with the average of 5.37 and 4.60, respectively. Variables of volume, pH and motility were not significantly different between both bulls with volume ranging of 7.17 – 7.20 ml, pH ranging of 6.65 – 6.66 and motility ranging of 58.08 – 59.29%, respectively. The fresh semen colour of Limousin and Simmental bulls were indicated by dominant color of milk white color. Semen consistency of fresh semen from both bulls was moderate. The ejaculation frequency and pH variables indicated the correlation of -0.32 in Limousine bulls, meaning that the higher the ejaculation frequency, the lower the pH  (acid), but the ejaculation frequency and motility of semen had the correlation of 0,34, indicating the more the semen ejaculation frequency, the higher the motility of spermatozoa. The motility of semen had the negative correlation with pH (-0.49). The higher the pH (base), the motility of spermatozoa tended to decline. Simmental bull showed also that semen ejaculation frequency with volume had correlation of -0.40, indicating that the higher the semen ejaculation frequency yakni, the lower the semen volume. Semen ejaculation frequency had correlation of 0.5 with mortality, indicating that the higher the semen ejaculation frequency, the higher the motility of spermatozoa.Keywords: Semen, ejaculation, volume, color, consistency, pH, motilit

PENAMPILAN TERNAK KUDA BENDI DI KECAMATAN TOMPASO KABUPATEN MINAHASA

PERFORMANCE OF HORSE  DRAWING CARRIAGE AT TOMPASO DISTRICT, MINAHASA REGENCY. This research  was conducted to evaluate  the performance of horse drawing carriage at Tompaso district was taken to be observed for the variables including chest circumference, body length, body heigth, and raising management, time duration of using horse power, horse feeding, feces observation, farmer environmental condition and general profile of Tompaso district. Result of this research showed that local horse at Tompaso was originally introduced from Makasar and Gorontalo, and body condition of this horse drawing carriage was this following standard performance, such as chest circumference of 131.5 cm, body length of 142.3 cm, body height of 131.38 cm, the average time duration of using horse power of 6.3 hours/day, worm eggs invested in horse faces of 237.5 eggs, and feed average consumption for animal of 25.12 kg/day with energy content in ration of 2.35 Mcal. Therefore, it can be concluded that performance of horse drawing  carriage at Tompaso district, Minahasa regency was ideally good. Keywords: Horse drawing carriage, Tompaso District, Minahasa Regency
