Abstract

A study to evaluate the productivity of Boer and Kacang goats dam was carried out for 2 years atResearch Institute for Goat Production, Sungei Putih-North Sumatera. The materials used were goatsowned by the institute. The parameters observed were total birth and weaning weights of kid, litter size,parity of dam, pre-weaning mortality and kidding interval. The rate of reproduction and productivity ofthe dam were estimated using Amir and Knipscheer methods and were statistically analyzed usingGeneral Linear Model. The results showed that the total birth and weaning weight of Boer goats werehigher (P<0.05) than that of Kacang goats, while litter size of Boer goats were higher (P<0.05) than thatof Kacang goats. The pre-weaning mortality of Boer goat 15.1 ± 6.02% was lower than that ofKacang. The kidding interval of Boer goats was higher (P<0.05) than that of Kacang. Parity of dam hadsignificant effect on all production traits (P<0.05) except for pre-weaning mortality. Dam reproductionrate of Boer (1.81) was higher than that of Kacang (1.78), while productivity of Boer goat (37.12kg/head/year) was higher than that of Kacang (18.12). It can be concluded that the reproductivity ofBoer and Kacang goats were similar, however the productivity of Boer goat had better than Kacang.

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

This research was carried out to make a difference and to predict genetic distance some sheep thatare genetically related to each other based on the body size measurements. Nineteen bodies size of 323sheeps of five sheep breeds; namely Barbados Black Belly Cross (BC), Garut Local (GL), GarutComposite (GC), Sumatra Composite (SC) and St. Croix Cross (SCC) were measured. Analysis ofvariance and canonical discriminant analysis, Mahalanobis distance, plotting canonical and dendogramwere performed using PROC GLM, PROC CANDISC, PROC CLUSTER and PROC TREE of SASsoftware ver. 9.0. Index Length, Width Slope, Depth Slope, Balance and Cumulative Index of GC sheepwere significantly higher than the four other breeds. Canonical discriminant analysis successfully coulddifferentiate among the five sheep breeds. All five breed were divided into two groups: the first groupconsisted of SCC, SC and BC; and the second group consisted of the GL and GC. The results of geneticdistance estimation showed that the SCC had a value of sheep genetic distance closest to SC (10.83) andBC (27.98), while GL had the closest distance to GC (66.60). The tail width, horn base circumference,horn length (canonical 1) and variable length of the tail and body length (canonical 2) were the breeddifferentiation variable in this study.
