Abstract

The objective of the research is determining the ICM isolation method to produce ESC. Blastocyst stage of DDy mice embryos were used in this study. Zona pellucida of blastocysts were removed by 0.25% pronase, the ICM isolation were done by enzimatic or immunosurgery method, and then they were cultured in DMEM-high glucose supplemented with mercaptoethanol, gentamycin, fetal bovine serum, and cumulus cells as feeder layer. The result of the research indicated that immunosurgery method yielding attachment rate and number ESC colony 93.85% and 43.08%, respectively, higher (P<0.05) than enzimatic method that weree 79.63% and 18.52%, respectively, but the viability of ICM cells were equal (P >0.05) that are 93.59% in enzymatic method and 98.56% in immunosurgery method. This research concluded that immunosurgery more effective method for isolation of ICM and ESC production than enzymatic method.

Abstract

The aim of study was to find out the best concentration and exposure time of calcimycin andionomycin in order to produce parthenogenetic embryos. Female Swiss Webster mice were fisrtlyprimed with Pregnant Mare’s Serum Gonadotropin (PMSG) and Human Chorionic Gonadotropin (hCG)with an interval of 48 hours. Sixteen hours after injection of hCG oocyte was collected by Dulbecco’sPhosphate Buffer Saline (dPBS) as a flushing medium. To separate the eggs from cumulus cells wereused hyaluronidase enzyme. The good quality oocytes were incubated in activation medium that isionomycin or calcimycin with a concentration of 3, 6, or 9 ìM and exposure time 1, 4, or 7 minutes. Toyield diploid embryos were used 5 ?g/ml cytochlasin B for four hours at 37°C, 5% CO2. Activatedoocytes characterized by the formation of pronuclei washed three times in Potassium SimplexOptimization Medium (KSOM) and subsequently cultured in the same medium until blastocyst stage.The results showed that oocytes activated at calcimycin, the best results was presented at concentration6 ?M and exposure time four minutes, i.e. activation rate reached 96%, cleavage rate 82% and blastocystrate 28%. On the other hand, oocytes activated in ionomycin, the best results was presented atconcentration 3 ?M and exposure time four minutes, i.e. activation rate reached 82%, cleavage rate64% and blastocyst rate of 4%. It was concluded that the best concentration and exposure timecalcimycin on mice oocytes were 6 ?M for four minutes, whereas ionomycin were 3 ?M for four minutes.

Abstract

This study aimed to evaluate study the influence of cattle hypophysis extract (HE) on the reproductive performance of post partum sows. Twenty landrace sows, 45 days after partum were divided into four groups, five sows each. All were injected with HE intramuscularly. Group I (P0) was injected with 3 ml of saline solution, Group II (P1) was injected with 3 ml contain of 10 mg/EH/Kg body weight (BW), Group III (P2) was injected with 3 ml contain of 20 mg/EH/Kg BW, Group IV (P3) was injected with 3 ml contain of 40 mg/EH/Kg BW. Every sows that showed the estrus symptom were inseminated artificially on the second days, twice each in the morning and evening. The intensity of estrus, length of estrus, number of service preconception (S/C), conception rate (CR), litter size, weight of piglet and milk production were recorded. The result showed that the score of estrus intensity in Group I, II, III and IV were 1.40; 2.40; 2.80 and 2.80 respectively with the length of estrus in each group were 4.40; 5.00; 5.00; 5.60 days respectively. The number of service in Group I, II, III and IV of each pregnancy were 4.40; 1.40; 1.00 and 1.20 with the CR were 0; 60; 100; and 80% respectively. The litter size produced of Group I, II, III and IV were 4.00; 6.00; 10.60; 8.40 respectively. The average of piglet body weight of Group I, II, III and IV were 1.20; 1.36; 1.56 and 1.35 kg respectively. The milk production of each sows of Group I, II, III and IV were 13; 41; 93; 88 g respectively. It can be concluded that cattle hypophysis extract improves the performance of post partum sows with the best level was 20 mg EH/kg of body weight. ABSTRAK Penelitian ini bertujuan mempelajari pengaruh pemberian ekstrak hipofisis terhadap performans reproduksi induk babi betina post partum. Penelitian ini menggunakan 20 ekor induk babi betina jenis landrace, dibagi kedalam empat kelompok perlakuan masing-masing terdiri atas lima ekor induk babi. Babi betina yang baru 45 hari menyapih anaknya diinjeksi dengan ekstrak hipofisis (EH) secara intramuskuler. Kelompok I (P0) diinjeksi dengan 3 mL NaCl fisiologis; Kelompok II (P1) diinjeksi dengan 3 mL NaCL mengandung 10 mg EH/kg bobot badan (BB); Kelompok III (P2) diinjeksi dengan 3 mL NaCl mengandung 20 mg EH/kg BB: Kelompok IV (P3) diinjeksi dengan 3 mL NaCl mengandung 20 mg EH/kg BB. Setiap induk babi yang menunjukkan gejala estrus diinseminasi pada hari kedua dengan interval dua kali, pagi dan sore. Peubah yang diamati adalah intensitas estrus, lama estrus, jumlah perkawinan per kebuntingan (S/C), angka konsepsi (conception rate/CR), litter size, bobot lahir anak, dan produksi susu. Hasil penelitian menunjukkan skor intensitas estrus kelompok I, II, III, dan IV masing-masing 1,40; 2,40; 2,80; 2,80 dengan lama estrus masing-masing kelompok secara berturut-turut 4,40; 5,00; 5,00; 5,60 hari. Nilai S/C masing-masing adalah 4,40; 1,40; 1,00; 1,20 dengan CR masing-masing 0; 60; 100; dan 80%. Total jumlah anak yang dihasilkan kelompok I, II, III, dan IV masing-masing adalah 4,00; 6,00; 10,60; dan 8,40 ekor. Rataan bobot lahir anak per ekor pada kelompok I; II; III; dan IV masing-masing adalah 1,20; 1,36; 1,56; dan 1,35 kg. Produksi susu per induk pada kelompok I, II, III, dan IV masingmasing adalah 13; 41; 93, dan 88 g. Simpulan dari penelitian ini adalah ekstrak hipofisis dapat meningkatkan performans induk babi post partum. Dosis terbaik adalah 20 mg EH/kg BB.
