Sonometri fetus kambing kacang usia 7 minggu hasil superovulasi menggunakan hormon PMSG
Abstract
Teknologi superovulasi dapat dimanfaatkan untuk meningkatkan sekresi endogen hormon kebuntingan. Salah satu manfaat dari peningkatan sekresi endogen hormon kebuntingan adalah perbaikan perkembangan lingkungan uterus selama kebuntingan. Kambing Kacang betina sebanyak 8 ekor dan telah dewasa kelamin dengan bobot rataan 22 kg dibagi ke dalam dua kelompok yaitu kelompok kontrol (tidak disuperovulasi) dan kelompok superovulasi menggunakan hormon Pregnant Mare Serum Gonadotropin (PMSG) dengan dosis 15 IU/kgBB. Kambing Kacang percobaan diserentakkan berahinya menggunakan PGF2α sebanyak 2 kali dengan selang 11 hari. Penyuntikan PMSG dilakukan bersamaan dengan penyuntikan PGF2α kedua pada kelompok superovulasi. Setelah berahi, semua kambing dikawinkan secara alami dengan pejantan pilihan. Fetus kemudian diukur secara ultrasonografi (USG) pada usia kebuntingan 7 minggu. Hasil pengukuran menunjukkan kelompok Kambing Kacang hasil superovulasi memiliki ukuran fetus yang lebih panjang daripada kelompok kontrol (P<0.05). Ukuran diameter amnion terpanjang dan terpendek serta tebal dinding uterus terlihat cenderung meningkat pada kelompok superovulasi dibandingkan dengan kelompok kontrol (P>0.05). Kesimpulan penelitian ini adalah superovulasi pada induk Kambing Kacang mampu meningkatkan pertumbuhan fetus sampai dengan usia kebuntingan 7 minggu.Downloads
