Abstract

The purpose of this research was to study genetic diversity in Indonesian sheep population usingmicrosatellite markers. A total of 18 microsatellite loci have been used for genotyping Indonesian sheep.Total sheep blood 200 samples were extracted from garut sheep of fighting and meat types, purbalinggasheep, batur sheep and jember sheep populations by using a salting out method. Microsatellite loci datawere analyzed using POPGENE 3.2 software. Based on this study obtained 180 alleles from 17microsatellite loci, while average number of alleles was 6.10 alleles (6 to 18 alleles) from fiveIndonesian sheep populations (garut sheep of fighting type, garut sheep of meat type, purbalingga sheep,batur sheep and jember sheep population). The average of observed heterozygosity (Ho) and expectedheterozygosity (He) values were 0.5749 and 0.6896, respectively, while the genetic differentiation forinbreeding among population (FIS), within population (FIT) and average genetic differentiation (FST)were 0.1006, 0.1647 and 0.0712, respectively. Genetic distance and genetic tree showed that Indonesiansheep population was distinct from garut sheep of fighting and meat types, purbalingga sheep, batursheep and jember sheep population. Based on this results were needed a strategy for conservation andbreeding programs in each Indonesian sheep population.

Abstract

The objectives of this study was to analyze the comparative ability of animal genetic, using evaluation of production that has important economic traits including Landrace, Yorkshire, and Duroc breeds of swine. A total of 49 swine consist 15 boars and 34 gilts, with average body weight of 18.50-21.50kg were used in this research. All of samples were raised in the same pen and feeding management. This research used the experimental method of Completely Randomized Design involving three treatments of animal breeds including Landrace, Yorkshire, and Duroc breeds. The data were analyzed by using analysis of covariance procedur General Linier Model and Least Square Means test. Boars and gilts were analyzed in separated data. The result showed that the effect of breed was significantly associated for all traits, but not for boars feed intake. The overall, Yorkshire and Landrace performed better than Duroc for average daily gain, feed conversion ratio, selection index, and age at 90 kg body weight. However, Duroc boars and gilts had the thinnest backfat followed by Yorkshire and Landrace.
