Abstract

This experiment used semen from a Simental bull, age 4 years old, 850 kg in weight and was healthy especially his reproduction organ.  Semen collection was done twice a week using an artificial vagina.  Soon after the semen was evaluated, it was diluted with tris aminomethan plus egg yolk and three concentration of glycerol namely 3% (G1), 5% (G2) and 7% (G3).  The semen was packed in 0.25 ml straw and maintained in equilibrium at 5oC for 4 hours and frozen in liquid nitrogen for 60 minutes.  Data collected were motility and percentage of living spermatozoa after freezing.  The experiment used a Completely Randomized Block Design.  The results showed that motility and percentage of living spermatozoa after freezing for each treatment were not significant (P>0.05).  The effect of those three treatments on motility and percentage of living spermatozoa after freezing were 40.2% and 59.6% for G1, 41.2% and 63.8% for G2 and 39.8% and 57.8% for G3, respectively, but the G2 treatment was better in protecting the quality of the spermatozoa than the other treatments. It was appeared that the level of glycerol at 5% concentration is an optimal dosage for maintaining the quality of the frozen semen

Abstract

Domba Palu merupakan rumpun domba lokal Indonesia berasal dari domba Kirmani dari Persia yang dikembangkan secara turun temurun dimulai pada abad ke-18 sehingga menjadi kekayaan sumber daya genetik ternak lokal Indonesia. Sejauh ini evaluasi pengembangan ternak domba Palu masih jarang dilakukan sehingga diperlukan penelitian perkembangbiakan yang bertujuan untuk menganalisis dinamika populasi dan tipe kelahiran domba Palu di Kecamatan Mantikulore Kota Palu. Penelitian dilaksanakan diempat kelurahan yang berada di Kecamatan Mantikulore yaitu kelurahan Kawatuna, Poboya, Talise Valangguni, dan Layana Indah pada bulan Juni 2023. Penentuan lokasi menggunakan metode purposive sampling. Untuk menentukan sampel, digunakan metode non probability sampling berupa accidental sampling. Pengumpulan data yang dibutuhkan dalam penelitian menggunakan metode observasi, wawancara, dan dokumentasi. Data yang diperoleh, dianalisis secara deskriptif. Variabel yang diamati adalah angka pemasukan ternak (angka kelahiran, pembelian, dan bantuan), angka pengeluaran ternak (angka kematian, penjualan, dan pemotongan), natural increase, dan tipe kelahiran. Hasil penelitian menunjukkan bahwa persentase kelahiran berdasarkan  induk sebesar 58.97% dan berdasarkan total populasi 32.48%, persentase kematian sebesar 5.76%, penjualan 4.12%, pemotongan sebesar 0.82%, natural increase 26.72% dan tipe kelahiran domba Palu adalah kelahiran tunggal.
