Abstract

Abstract. Aceh cattle is one of Indonesian germplasms with many advantages for development in the tropics. The purpose of the study was to select Aceh bulls based on newborn calves measurements. Data comprised 294 calves from nine bulls. The variance components of heritability (h2) and repeatability (r) estimation were obtained from data analysis using SPSS 16.0 software. Breeding value was estimated on the newborn calves measurement namely birth weight (BW), thoracic girth (TG), withers height (WH) and body length (BL). The genetic parameter values of newborn measurements were moderate category (0.10< h2 <0.30) for heritability (h2) and moderate (0.10<r<0.30) to high (r>0.30) for repetability (r). The average of newborn calves measurements was 13.99+1.96 kg (BW), 54.50+3.24 cm (TG), 56.37+3.41 cm (WH) and 45.13+2.86 cm (BL). Bull A (ID: P.075) was the best bull with cumulative breeding value 5.05. Key words: Aceh cattle, newborn measurements, genetic parameters, breeding value Abstrak. Sapi Aceh merupakan salah satu plasma nutfah Indonesia. Sapi ini memiliki banyak kelebihan untuk dikembangkan di daerah tropis. Tujuan penelitian ini adalah untuk menyeleksi pejantan sapi Aceh berdasarkan ukuran lahir pada pedet. Data yang digunakan terdiri dari 294 ekor pedet dari sembilan pejantan. Estimasi komponen ragam heritabilitas dan estimasi ripitabilitas dianalisis menggunakan perangkat lunak SPSS 16.0. Estimasi nilai pemuliaan dihitung berdasarkan ukuran lahir pedet: berat badan (BB), lingkar dada (LD), tinggi gumba (TG) dan panjang badan (PB). Nilai parameter genetik pada ukuran lahir termasuk kategori sedang (0,10<h2<0,30) untuk heritabilitas (h2) dan kategori sedang  (0,10<r<0,30) sampai tinggi (r>0,30) untuk ripitabilitas (r). Rata-rata ukuran lahir pedet adalah 13,99+1,96 kg (BB), 54,50+3,24 cm (LD), 56,37+3,41 cm (TG) and 45,13+2,86 cm (PB). Pejantan A (ID: P.075) merupakan pejantan terbaik dengan nilai pemuliaan kumulatif sebesar 5,05. Kata kunci: Sapi Aceh, ukuran lahir, parameter genetik, nilai pemuliaan

Abstract

RAPD analysis to determine the diversity, status and genetic close relatioship Batur with Merino, Garut, Thin Tail and Fat Tail sheep genomic DNA was used in 27 Batur, 15 Merino, 17 Garut, 15   Thin Tails and  Fat Tails animals. The process of RAPD-PCR used five primers of 10 nucleotides. PCR results were electrophoresed with 2% agarose gel. Identified similarities and differences between individual RAPD bands one and cross-sample of the population, genetic distance and closeness of genetic relationship. The process 89 sample  sheep RAPD-PCR generated of 4189 band from 100 to 1500 bp which consisted of 91 type. Batur sheep samples produced bands at most (1666 tape) and the lowest Fat Tails (493 bands). The number monomorfism of bands most of the Batur (891 bands) and the lowest Garut (170 bands), but the polymorphism  bands highest  of the Batur (775 bands) and the lowest Fat Tails (262 bands). Between individuals within populations have similar genetic Merino highest and the lowest Thin Tail. Cross-population genetic similarity is highest individuals in the population Batur and Merino, while the lowest Merino and Thin Tail. The closest genetic distance was Batur with Merino population and the most apart distant Merino with Thin Tail or Merino and Fat Tails. Batur sheep population has the closest genetic relationship with the Merino and the most apart distant is with Fat Tail.
