Data of body weight of Garut sheep and its crossbreds of 488 head, consist of 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).

A study was conducted to investigate the milk production capacity and preweaning performance of the prolific Priangan sheep, at sheep breeding station of the Research Institute for Animal production, Bogor using 126 ewes during three lambing periods in three consecutive years. The milk production was estimated weekly, started at day 7 after lambing date, till lambs were weaned at 90 days of age. The results showed that total milk production was significantly affected (P<0.05) by parity and the number of lambs born with average daily milk production of 519.5 g head-1 day-1. Estimated total milk production was 43.6 kg/lactation (N = 126; SD = 7.8; CV = 19.4%; range = 28.7-53.6 kg). According to the dam parity, the highest milk production was estimated at third parity (40.1 kg head-1 lactation-1), whereas on the basis of litter size, ewes with twin born lamb had the highest production (39.9 kg head-1 lactation-1). The preweaning lamb performance (weaning weight and preweaning daily gain) was significantly affected (P<0.05) by ewe parity, sex, litter size and type of birth and weaned, with the average weaning weight of 10.62 kg (N = 208; SD = 3.37; CV = 25.08%) and 130.9 + 41.8 g head-1 day-1 (N = 208; SD = 33.5; CV = 31.26%), respectively. Where as lamb birth weight was significantly affected (P<0.05) by ewe parity, sex and the number of lambs bornwith average of 2.39 kg (N = 208; SD = 0.66; CV = 9.8%). Key words: Milk production, prolific sheep, preweaning performance

It is important to know body measurement because it could be used to estimate body weight as well as to differentiate the chrateristic of body measurement and shape of animal due to different breed or environment. This research was carried out to study morphometric characteristic of body size and body shape from 78 of Garut sheep (GG), 29 HG sheep {crossbred between St. Croix (HH) and Garut sheep (GG)}, 36 MG sheep {crossbred between Mouton Charollais (MM) and Garut sheep (GG)}, 62 MHG sheep (MG x HG) and 38 HMG sheep (HG x MG). Body part measured were wither height (X1), rump height (x2), body length (X3), chest width (X4), chest depth (X5), hip width (X6), chest girth (X7), cannon circumference (X8) and hip length (X9). Data obeserved were analised using t test and Principle Components Analysis (PCA). Based on PCA it was showen that chest girth was the primary identity for body measurement on males and females of Garut, HG, MG, MHG and HMG with its Eigenvector value 0.689; 0.709; 0.689 and 0.681 respectively. The primary indentity for body shape of Garut sheep were chest girth and hip heigth with Eigenvector value -0.600 and 0.551 respectively. The primary indentity for body shape of HG sheep were body length with Eigenvector value -0.725. The primary indentity for body shape of MG sheep were chest girth, rump heigth, and wither heigth with Eigenvectors value: -0.600; 0.558 and 0.555 respectively. The primary indentity for body shape of MHG sheep was wither height with Eigenvector value 0.608. The primary indentity for body shape of HMG was body length with Eigenvector value 0.764. Body shape of HG and MG sheep is different than that of Garut sheep, but the body shape of MHG and HMG were close to Garut body shape. This result indicated that the adaptability to environment of HMG and MHG is close to that of Garut sheep. Key words: Sheep, Body Size, Body Shape.

Coat colour is a qualitative trait whose expression is controlled by genes and could be used as a characteristic of sheep breed and could be used as a trade mark for certain sheep breeder enterprise. The research was done to study the coat color pattern in Garut sheep and its crossbred. In this study 178 heads of sheep was used which consisted of 64 Garut sheep (GG); 24 MG sheep (50% M and 50% G); 14 HG sheep (50% St. Croix and 50% G); 20 HMG sheep and 56 MHG sheep. HMG and MHG sheep are compost of 25% St Croix; 25% M. Charolais and 50% Garut. Phenotypic observation of coat colour were done by visualization and from the picture of sheep as individual identity in each position from the right; the left, front and rear sites. Sheep coat colour pattern in this study was largely determined by 5 main alleles: white or tan (65.7%), wild (17.4%), badgerface (14.6%), Light badgerface (0.6%) and black and tan (1.7%) that present at the Agouti locus. Other locus that determine the coat colour pattern in this study are Albino (C); Australian Piebald (AsP); Brown (B); Extension (E); Pigment Head (Ph); Roan (Rn); Spotting (S); Sur Bukhara and Sur Surkhandarya (SuB/SuS) and Ticking (Ti) all of these locus increase the variation of coat colour pattern.

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. Key words : Prolific sheep, lamb production

Lamb mortality is highly related to ewe behavior at lambing. The purpose of this research was to study ewe lambing behavior and lamb behavior after birth of Garut (GG) sheep and its crosses with St. Croix (HH) and Moulton Charollais (MM). The number of observation were 106 head, consist of 32 GG; 23 of HG; 14 of MG; 31 of MHG and 6 of HMG crossed ewes. Analysis of variance of general linear model (GLM) for different number of sample was used to study ewe behavior of different group of ewes. Linear regression was used to analyze relationships between lambing behavior; times from birth to stand up and ewe body weight. While relationship between labor time and parity or type of birth were analyzed descriptively. Before lambing, ewes stood up, lain down, walked in circle, vocalized, urinated, flehmened, and pawed. HG and HMG ewes stood up less often than other breeds (P<0.05). Lambing time was distributed randomly for GG, HG, MG and MHG ewes, but HMG ewes mostly lambed at night (66.67%). Labor time of HMG ewes was significantly shorter than other breeds (P<0.05) and was not affected by birth weight, birth type and neither by parity. The ewes generally lambed in lay down position. After lambing, ewe normally stood up and cleaned the lamb immediately. The cleaning generally begin from the head progressed down to the whole body. The success for lamb to stand up was not significantly different among breeds. Key Words: Lambing Behavior, Garut, Crossbreeding, St. Croix, Moulton Charollais

Crossing of Garut (GG) sheep with St. Croix sheep (HH) and Moulton Charollais (MM) resulting HG sheep (♂HH X ♀GG) and MG sheep (♂MM X ♀GG) was done by Indonesian Research Institute for Animal Production. The work continued by crossing MG and HG sheep to obtain HMG (♂HG X ♀MG) and MHG (♂MG X ♀HG) 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.

Based on previous study it is agreed that Von Bertalanffy model is the best fitted growth curve model with highest acuracy compared to Gompertz or Logistic models. For that reason in this study Von Bertalanffy model was used to study growth characterisics of Garut sheep and its crossbred. Relative superiority of crossbred sheep compared to Garut sheep in mature size parameter (A) based on Von Bertalanffy model were respectively: M. charolain X Garut = 19.26%; Hair sheep X Garut = 8.08% and MG X HG or HG X MG = 4.22%. While relative superiority of crossbreds compared to Garut in rate of maturing (k) were respectively: MG = -4.91%; HG = -1.34% dan MHG/HMG = 6.05%. Based on its relative superiority mature size parameter (A) and rate of maturing (k) MHG sheep had prospect for more developed due to its performance in term of high mature body weight, faster in reaching standard of slaughter body weight (35 kg) at 440 days, and it is considere as more eficient in biological and economicaly.

Indonesian archipelago consists of five main islands and more than seventeen thousand of small islands. These small islands are very effective as natural barrier to the spread of contagious animal diseases. This situation is very advantageous to develop many programs such as beef cattle farming to support beef self sufficient program in 2010. However, there are some constraints in developing of these small islands, namely human resources, natural resources, infrastructure, mean of communications and transportations and lack of intra sector integrated coordination. In taking the advantageous of developing small islands as a screening base and quarantine area, animal production technologies and veterinary science are much needed. The development can be done in integration with transmigration development program so that the beef cattle development could become source of income and job opportunity for the transmigran and local inhabitant as well. Beef cattle farming scheme are recommended by doing cow-calf operation or fattening. Political support from government and legislative are needed in establishment of infrastructure in the area chosen as beef cattle farming location. Besides, it need facilitations in land procurement for beef cattle farming, legal aspect, supports of law enforcement, simple regulation in land used and zone management planning, regulation in controlling beef importation, and credit with minimum interest rate. Key words: Small islands, beef cattle, policy
