The research was aimed to study factors that affected litter size (JAS), lamb survival (DHA) and litter weight at birth (BL) and at weaning (BS) on prolific ewes. Production records during the year of 1981-1993 were used in this study (1,437 records). Ewe genotypes (G), management levels (M), ewe parity (P) were the fixed effect and ewe gestation gain (PKB) was a covariable that included in the model. Analysis of variance for unbalanced data with general linear model procedure were used. Mean JAS was 1.77. Sources of variation that affected JAS were G, M, P-M interaction, and PKB. One copy of FecF gene increased the number of lambs born by 0.8. Changing toward a better management levels was followed by an increase of JAS. An increased of one kilogram PKB was also followed by an increase of 0.04 litter size born. The mean of BL was 3.43 kg and the sources of variation that affected BL were G, M and P-M interaction. At all management levels, primipara ewes had lower litter size at birth and litter birth weight than the pluripara ewes. Mean DHA found was 73.93%, it was affected by G-M interaction, P and PKB. First parity ewes has 11% lower of DHA than second parity ewes. An increase of 1 kg PKB was followed by an increase of 2.3% of DHA. Sources of variation that affected BS were G-M interaction, P and PKB. Mean BS in this study was 13.12 kg. Â Key words : Prolific sheep, lamb production

Four half-sib families (n = 382) consisting predominantly of ITT x Merino x Merino backcross progeny, including some F2 progeny were used to analyze QTL for two production traits (Birth weight = BW1 and Body weight at 360 days = BW360). The study exploited differences in weight performance between the Merino and ITT sheep. A total of 141 informative microsatellite markers were used in a genome-wide scan covering the 26 autosomal sheep chromosomes. QTL analysis was conducted online using QTL Express. This study reports the effect of QTL for birth weight on Chromosomes 5 (p < 0.05) at 112cM (0cM-128cM). Location of candidate genes for birth weight was predicted at the region of flanking markers MCM527-BMS1247. A QTL for BW360 days existed on Chromosome 18 (p < 0.01) at 104cM (25.0-125cM). Location of candidate genes related to production traits for body weight 360 days was predicted at the segment of flanking markers of CSSM018-TMR1. Only the QTL on Chromosome 18 retained significance (p < 0.01) under experiment-wide significance testing. This QTL region is being examined for candidate genes by investigating to the homologous human chromosomal segments.

Penelitian ini bertujuan untuk mengetahui sifat kualitatif dan kuantitaif kerbau lokal. Metode penelitian yang digunakan adalah survey, penentuan sampel berdasarkan purposive sampling. Lokasi penelitian adalah Kabupaten Serang, Pandeglang dan Kabupaten Lebak Propinsi Banten. Pengambilan data dilakukan melalui observasi dan pengukuran. Jumlah kerbau yang diteliti sebanyak 300 ekor terdiri atas 150 ekor kerbau jantan dan 150 ekor kerbau betina dewasa. Data dianalisis menggunakan analisis statistik deskriptif dan sidik ragam. Hasil penelitian diperoleh sifat kualitatif untuk warna kulit dan kaki adalah abu-abu gelap, bentuk tanduk umumnya melingkar ke bawah, garis kalung ganda, unyeng-unyeng ditemukan pada kepala, pundak dan pinggul. Ukuran-ukuran tubuh kerbau jantan dan betina berturut-turut: lingkar dada (cm) 171,98±5,00; 161,33±4,83; dalam dada (cm) 65,13±3,97; 59,53±5,76; panjang badan (cm) 122,10±6,40; 120,00±2,03; tinggi pundak (cm) 130,02±2,80; 118,99±3,20; tinggi pinggul (cm) 103,42±2,27; 105,28±2,87; lebar pinggul (cm) 32,50±1.61; 31,41±1,39; panjang kepala (cm) 41,99±1,42; 41,39±1,55; lebar kepala (cm) 20,21±1.83; 19,30±1,15; lebar ambing (cm) ; 47,15±5,20; lebar teracak (cm) 15,89±1,77; 14,84±1,07; dan lingkar skrotum (cm) 15,88±0,67. Tidak terdapat perbedaan yang nyata (P>0,05) ukuran tinggi pundak, tinggi pinggul, panjang kepala, lingkar skrotum serta lebar teracak pada kerbau jantan dan betina pada subpopulasi Serang, Pandeglang dan Lebak, akan tetapi terdapat perbedaan yang nyata (P<0,05) ukuran lebar pinggul, panjang badan, lingkar dada, dalam dada, dan lebar kepala. Kerbau yang berada di lokasi penelitian dari kajian sifat kualitatif dan kuantitatif dapat digolongkan sebagai kerbau lumpur.Kata Kunci: keragaan sifat kualitatif, sifat kuantitatif, kerbau lokal
