KUALITAS KOLOSTRUM KAMBING PERANAKAN ETAWAH (PE) PADA BERBAGAI PERIODE LAKTASI DAN TIPE KELAHIRAN DI UPT PT DAN HMT SINGOSARI KABUPATEN MALANG

Colostrum Quality of Etawah Crossbreed in Various Lactation Periods and Types of Birth at PT and HMT Singosari, Malang District. Etawah crossbreed is one of the Indonesia’s local genetic resources. This research aimed to evaluate the colostrum characteristics of Etawah Crossbred goats with various lactation periods and types of birth (litter size). Twenty Etawah Crossbred goats were selected for the experiment, based on lactation period 1, 2, 3, 4 and 5 (4 goats per lactation). Each lactation period had 2 doe-s with a single and multiple births. Colostrum was milked at 0; 24; 48; and 72 hours postpartum and analyzed using Lactoscan. Data were analyzed using Analysis of Variance followed by Duncan's Multiple Range Test of SAS statistical analysis. Lactation period significantly affected colostrum fat and protein (P 0.05). Type of birth also significantly affected colostrum fat, lactose, and protein (P 0,05). Tipe kelahiran berpengaruh sangat nyata terhadap lemak, laktosa, dan protein kolostrum (P<0,01) kecuali SnF (P<0,05). Kesimpulan dalam penelitian ini adalah kadar lemak, laktosa, dan protein kolostrum kambing PE dengan periode laktasi 3 lebih tinggi dibandingkan periode laktasi 1, 2, 4, dan 5. Kadar lemak, laktosa, dan protein mengalami peningkatan pada periode laktasi 3 selanjutnya mengalami penurunan pada perioe laktasi 4. Kolostrum kambing PE dengan kelahiran tunggal menunjukkan bahwa kadar lemak, laktosa, protein, dan SnF lebih tinggi  dibandingkan kelahiran kembar.
