Abstract

Season, rainfall, day of rain, temperature, humidity, year and farm are fixed effects, which have been reported to influence milk yield. Those factors are often linked together to contribute to the variation of milk production. This research is addressed to study the fixed effect factors, including lactation curve, which should be considered for genetic evaluation of milk yield based on test day records of dairy cattle. The data were taken from four different farms, which were PT. Taurus Dairy Farm, BPPT Cikole, Bandang Dairy Farm, and BBPTU Baturraden. In total of 16806 test day records were evaluated, consisting of 9,302 at first and 7,504 at second lactation, respectively. The results indicated that fixed effects were very specific and the influences had different patterns for each farm. Consequently, in a genetic evaluation, these factors such as lactation, temperature, year, day of rain, and humidity need to be evaluated first.  Ali-Schaeffer curve represented the most appropriate curve to use in the genetic evaluation of dairy cattle in Indonesia. Key words: Fixed Effects, Milk Production Curve, Test Day, Dairy Cattle

Abstract

Good Dairy Farming Practice (GDFP) merupakan serangkaian tata kelola peternakan sapi perah yang baik guna optimalisasi produksi produk peternakan. Permasalahan utama dalam pengembangan sapi perah adalah ketersediaan pakan terutama pakan hijauan. Ketersediaan pakan hijauan selalu fluktuatif mengikuti pola musim. Perubahan pola musim yang dihadapi setiap tahunnya oleh peternak menuntut peternak untuk melakukan pengawetan bahan pakan berupa hijauan (tebon jagung) dengan cara ensilage. Proses ensilage tersebut menghasilkan cairan bioproses tebon jagung yang masih memiliki manfaat bila digunakan untuk ternak. Kegiatan penyuluhan yang melibatkan peternak anggota kelompok ternak “Sentra Dairy Farm” bertujuan untuk memberikan pengetahuan mengenai GDFP dan pemanfaatan cairan bioproses tebon jagung sebagai Direct Fed Microbial (DFM) yaitu tambahan starter ensilage. Hal tersebut diharapkan mampu membantu peternak dalam meningkatkan tata kelola sehingga produksi ternak menjadi optimal. Hasil dari penyuluhan yang dilakukan menunjukkan indikator kesuksesan program berupa persentase kehadiran peserta (75%) dan peningkatan pengetahuan peternak sebesar 99%.
