In attemp to increase the productivity of Garut sheep, Indonesian Research Institute for Animal Production has crossed Garut sheep (GG) with St. Croix sheep (HH) that has high frame body size and adaptable to the hot climate (in 1995) and with Moulton Charollais sheep (MM) that has high body weight gain and good milk production to raise multiple birth (in 1996). The objective of this research was to evaluate the ewe productivity of Garut sheep and its crosses with St. Croix and Moulton Charollais. This research was conducted at Animal Research Station, Bogor from 1995 to 2002. In this study the crossing was done using frozen semen of M. Charollais and ram of St. Croix so that the real performance of these sheep under Indonesian condition is not known. So that the relative superiority of these crosses is calculated from the percentage of the differences between traits mean of crossbred and purebred divided by trait means of purebred Garut, except for the threeway crosses (MHG and HMG) is calculated from the difference between the means of threeway crossbred trait with the means of two parents (MG and HG). It is concluded that HG and MHG show higher dam productivity than GG, it can be seen from their litter weight at birth and weaning. In poor feed condition GG showed higher productivity than the crossbred sheep (MG and HG), but MHG/MHG showed higher relative superiority compare to their parents (MG and HG). In good feed condition HG and MHG/HMG sheep showed higher productivity than Garut sheep. The relative superiority of HG sheep is 26.40% over GG and for MHG/HMG is 11.24% over their parents (MG and HG). Â Â Â Key Words: Garut Sheep, St. Croix Sheep, M.

Crossing of Garut (GG) sheep with St. Croix sheep (HH) and Moulton Charollais (MM) resulting HG sheep (âHH X âGG) and MG sheep (âMM X âGG) was done by Indonesian Research Institute for Animal Production. The work continued by crossing MG and HG sheep to obtain HMG (âHG X âMG) and MHG (âMG X âHG) sheep. The study was continued by selection program based on phenotypic performance. Estimation of breeding value and genetic trends were done in order to study the effectiveness of selection program and to study the genetic progress of each breed. The breeding value was estimated by Best Linear Unbiased Prediction (BLUP) method using Variance Component Estimation (VCE4) software to calculate variance component and using Prediction and Estimation (PEST) to calculate Breeding Value. Genetic variations of composite sheep were generally higher than Garut sheep, represented by higher estimated heritability value. Genetic correlation of body weight at diffrent age is high, that makes selection at one age could also increase body weight at any level of age. In general of this population shows positive genetic trend, but fluctuated from year to year. Composite breed tend to have higher estimated breeding value than Garut sheep. Selection method that was practiced in this population showed in line with selection method using breeding value criteria.

PO cattle is one ofÂ the local cattle with high genetic diversity. The aim of this research was to study genetic diversity of PO cattle in smallholder farmerÂ based on morfology and molecular markers. This research was conducted at breeding center in East Java and Central Java include Tuban, Lamongan and Blora regency, since June until December 2008. Â PO bull used were of 18 months until 24 months of age and cow of 24 months until 36 months of age or at first calving as much as 30 head each location. The variables measured were body weight, body length, withers height, hip height, shoulder point width, chest girth, chest depth, canon bone circumference, head length and head width. Data were analyzed using descriptive statistic, average analysis between subpopulations, discriminant and canonical analysis and mahalanobis distance was done by SAS DISCRIM procedure. Whole blood were collected to get the data of polymorphism DNA microsatellite using technology of PCR and electrophoresis using 6 microsatellite loci. Variable measured were number and size of Â alel, alel frequency, heterozygosity,genetic distance and fixation index (F-stat). Data were analyzed using analysis of Microsate Toolkit, GENEPOPV4, MSA (Microsatellite Analyser) and Mega 4. The result showed that Blora and Tuban subpopulation have genetic diversity which is relative lowerÂ compared to that of Lamongan. The genetic distance which was close presented by Tuban and Blora subpopulation while Lamongan and Tuban subpopulation show far genetic distance. The result of canonical analyses showedÂ high correlation on shoulder point width, head width, body length, withers height and hip height variable so this five variable can be used as distinguishing variables among subpopulation. The result of molecular genetics analysis using microsatellite showed that highest frequency of alel presented by HEL9 locus at Tuban population so this loci have the high polymorfism. The genetic differentiation among subpopulation showed by differentiation FST value among six lociÂ indicating the increasing of inbreeding in Â the three subpopulations.

Does reproduction performance could be expressed by her ability to give birth and to give milk to their kids during the pre-weaning period. This study was aimed to evaluate the reproductive performance of Boer, Kacang and Boerka does; and was carried out for two years at Research Institute for Goat Production, Sungei Putih. The materials used were goats owned by the institute. The parameters observed were: litter size, parity of does, preweaning mortality, kidding interval and sex ratio of kids. The rate of reproduction of the does was estimated using Amir and Knipscheer methods and were statistically analyzed using General linear model. Results showed that litter size and kidding interval of Boer goats were higher (P < 0.05) then that of Kacang goats, while the Boerka goats was in between. The mortality at preweaning of Boer goats was lower (P < 0.05) then that of Kacang goats, while the Boerka goats was in between. The percentage of kid sex ratio of three breeds were fluctuated. Parity of does had significant effect on all reproduction traits (P < 0.05) except for sex ratio of kids. The does reproduction was smallest at the first parity, and increased with the increase of parity from one to four, and then decreased in subsequent parities. The highest does reproduction rate was found in the Boerka (1.82), followed by Boer (1.80) and Kacang (1.80). It is concluded that the reproductive performance of the three breed female goat was relatively the same. Key Words: Performance, Reproductive, Boer, Kacang

Information about correlations among behavioral traits and production traits may facilitate using easily measured traits to be used as alternative criteria for indirect selection to improve other traits in sheep. The purpose of this study was to estimate correlations among behavioral and production traits of five breeds of sheep.Â A total of 128 head of weaned lambs and 168 ewes with nursing lambs of five breeds were used in this study, i.e. Barbados Black Belly Cross (BC), Composite Garut (KG), Local Garut (LG), Composite Sumatra (KS) and St. Croix Cross (SC). Temperament was assessed in a test arena, for subsequent association with growth rate and ewe productivity. Analysis of variance of production and behavioral traits among breeds was carried out using PROC GLM of SAS software Ver. 9.0.Â PROCCORR was used to estimate correlations among production and behavioral variables. Weaned lambs that were more docile towards the observer had higher daily gains.Â Ewes that bleated more frequently when separated from their lamb had higher lamb weaning weights and lamb survival than ewes bleating fewer times under the same conditions. In BC ewes, a positive correlation was observed between frequency of bleats and lamb survival. Key Words: Sheep, Behavior, Growth rate, Ewe productivity

Improving sheep productivity can be conducted by genetic improvement and improving environmental factors. Genetic improvement usually can be done by selection and creating composite or synthetic breed by crossbreeding. Composite breed created by crossbreeding between different breeds and followed by selection. The study of crossing between Sumatra sheep with fat-tail sheep from East Java, St . Croix hair sheep (US) and Barbados Blackbelly hair sheep has been carried out since 1986, and show that the crossbred are better in term of production and reproduction . In 1996/1997, the first generation (F1) of composite breed (KOM) has been created by crossing between Barbados Cross (BC) rams and St . Croix Cross (HC) ewes or reciprocally. The second generation (F2) of composite breed has been created by inter-se mating . However, F1-KOM and F2-KOM Â vary in their performances, therefore selection should be conducted. The results showed that birth weight and weaning weight of crossing between BC rams and HC ewes tended to be heavier than those of reciprocal crossing between HC rams and BC ewes, but the differences were not significant (P>0 .05) . Birth weight and weaning weight of crossing between BC rams with HC ewes and reciprocal cross were 2.48 _+ 0.70 kg (n=791), 12 .50 _+ 3 .26 kg (n=640) and 2.37 _+ 0.62 kg (n=147), 12 .29 _+ 3.30kg (n=122), respectively . Meanwhile, observations of inter-se mating of Fl-KOM showed that the weight at the first mating was 26 .7 _+ 3.82 kg (n=80), age of dam at the first lambing was 15 .7 _+ 1 .73 months (n=83), weight at post-partum was 29 .86 _+ 3 .30 kg, and litter size at the first parity was 1 .43 _+ 0.59 (n=83) . The mean of age at the first mating of KOM was around 10 .7 months. Mean of mating weight at the second parity was 28 .29 +_ 3 .51 kg (n=11), age of dam at the Â second lambing was 20.6 _+ 1 .99 month (n=11), post-partum weight was 26 .92 _+ 4.03 kg (n=11) and litter size was 1 .64 _+ 0.81 (n=11) . Weaning weight of Fl-KOM, F2-KOM, BC, HC and St. Croix (H) after adjusted by season, sex, age of dam and type of birth were significantly different among Fl-KOM with F2-KOM, BC, HC, and H. However, there were no significantly different among F2-KOM with BC and HC. The results of the study indicated that for improving selection respons, the corrections or adjustments of environmentally induced superiority (sex, type of birth and age of dam at lambing) for every genotype and certain generation should be conducted, in order to increase the rate of genetic improvement.

Data of body weight of Garut sheep and its crossbreds of 488 head, consist ofÂ 149 head of Garut sheep, 115 head of St. Croix X Garut (HG), 68 head of Mouton Charollais X Garut (MG), 101 head of MG X HG (MHG) and 55 head of HG X MG (HMG) which is collected from Indonesian Research Institute for Animal Production at Bogor station were used in individual growth curve analysis. Three growth curve non linier model were used in this study i.e Logistik, Gompertz and Von Bertalanffy models. Comparisons were made among these models for goodness of fit, biological interpretability of parameters and computional ease and effect of genotype and environment in them. Least square means growth curve parameters which have biological interpretability were used to compare effect the genotype, interse mated procces and estimated heterosis effect. The result indicated that Von Bertalanffy was the best model in fitting the data from Garut and Crossbreds although the model needed more iteration than others in computations. All models have good biological interpretability especially for parameter mature size (A) and rate of maturity (k). Genotype, year of birth, sex and type of birth reared were important effects (p<0.01) in mature size (A) for all models except effect of type of birth rearing (P<0.05) in Logistic model. Year of birth had important effect (p<0.01) in rate of maturity (k) for all models. Genotype, year of birth, sex, parity and type of birth reared also had important effect (p<0.01) in parameter b/M; except b parameter in Von Bertalanffy was affected significantly by sex (P<0.05). Key Words: Growth Curve, Garut Sheep and Crossbreds, Relative Superiority
