A complete block design was applied to employ 40 weaner goats, initial weighing average of 14.6 kg, which were grouped into 5 supplementary treatments, i.e. 125, 250, 300, 350 dan 400 g of skim milk/d. Each animal received.1.25 kg gliricidia leaves. Mixed pasture was consumed freely. The research was conducted in Tanjungrejo village, Tongas district, Probolinggo. A digestibility study was conducted for 7 days. Measurements included nutrient intakes and digestibilities, liveweight gain, and feed conversion ratio. Data were analyzed using the GLM procedure of SAS (SAS, 1986). The results showed that the medium skim milk level (300 g/d) gave the highest dry component digestibility. Cell wall digestibility from the group given 125-300 g skim milk/d was higher (P<0.05) than those given 350-400 g/d. No significant (P>0.05) difference in organic matter or protein digestibility was found among treatments. Supplementation with 350 g skim milk/d gave higher protein or digestible protein consumption (P<0.05), while supplementation with 125 g/d gave the best feed utilization efficiency. Levels at 125-250 g skim milk/d gave weight gain of about 65 g/d, while at more than 250 g gave 57 g/d or less. The best feed conversion ratio (7.8) was obtained in the group fed 125 g skim milk/d. In order to optimize microbial activity in the rumen, provision of slowly rumen degradable protein sources such as legumes, or rumen undegradable protein is of great importance.

Two years field study has been carried out in the Purwakarta district , West Java, to evaluate sheep productivity of Sumateran Composite (K) and Barbados cross (BC) breeds introduced to the farmers, compared with locally thin tail sheep breed (L) that were maintained by the farmers. Genotype compositions of K sheep were Barbados Blackbelly 25%, St. Croix 25%, and Sumateran sheep 50%; and for BC were Barbados Blackbelly 50% and Sumateran sheep 50%. Sheep those were introduced was new breed from breeding improvement of Indonesian Research Institute for Animal Production. Litter size of K, BC, and L ewes was 1.3; 1.4; and 1.5 respectively. Pre-weaning mortality rate were 5.0; 5.0 and 8.0% respectively for K, BC, and L lambs. Ewe Reproduction Rate (LRI = number of lamb at weaning/ewe/year) of L (2.14) was higher than BC (2.0) and K (1.85). The ewe productivity (PI = kg lambs/ewe/year) is the average of weaning weight timed LRI. Because the weaning weight of L (7.0 kg) were significantly lowest than BC (10.5 kg) and K (9.25 kg) will affect on PI. PI of L (14.98) ewe were significantly (P<00.5) lowest than BC (21) and K (17.11). Body weight of crossbred (K X L and BCxL) under the same physiologic status were similarly with BC and K. According to the result of productivity evaluation of introduced sheep breed in the field condition, can be sumarize that productivity of K and BC sheep were significantly better than locally thin tail sheep.

Under semi-intensive conditions, the composite genotype (K) (25% Barbados Blackbelly; BB, 25% St. Croix; SC, 50% Sumatra Thin Tail; DETS) showed relatively have similar weaning weight as compared to other contemporary crossbred, therefore under intensive conditions (confined), they are expected to have better performances. The objective of the study are to find performances of the second generation composite genotype lambs and the first generation performances of the ewes, as well as several genetics parameters under intensive conditions, and compared to the Barbados Blackbelly Cross (BC) as contemporary crossbred. The growth of pre- and post-weaning of BB crossbred (BC) and the second generation of composite genotype (K-F2) are relatively the same. Growth curve using Von Bertalanffy model with the equation of Wt (t) = A*(1-B*e**(- K*t)), show that the equation for BC is Wt (t) = 26.8(1-0.92e**(-0.01t) and for K-F2 is Wt(t) = 26.1(1-0.92e**(-0.01t). This equation indicate that the growth of BC and K-F2 is not significantly different. The BC and K-F2 genotype reach maturity at the weight of 26.8 and 26.1 kg, respectively, and both with rate of reaching maturity of 0.01. Mating weight and weight at lambing of those two genotypes are around 29 - 30 kg dan 31 kg, respectively. The mean of litter size of BC and K-F1 are 1.52 and 1.48, respectively or around 1.5. The average litter size at weaning are 1.39 and 1.34, respectively for BC and K-F1. This means that pre-weaning mortality are around 5.37 and 9.76%, respectively for BC and K-F1. The lambing interval of BC and K-F1 are 211 and 223 days, or 0.58 and 0.61 year, respectively. Therefore the reproductive rate (RR) of the respective genotype are 1.39/0.58 = 2.39 and 1.34/0.61 = 2.19, respectively. The average of litter weight at weaning (LWW) of BC x BC, SC crossbred (HC) x BC and K-F1 x K-F1 are 11.62, 12.60 and 11.83 kg, respectively. Therefore based on the ewe genotype the LWW of BC and K-F1 are 11.74 and 11.83 kg, respectively. Flock productivity (FP) for those two genotypes per year are 20.24 and 19.39 kg, respectively for BC and K-F1. Dam productivity index (DPI) that calculated as /ewe weight for those two genotypes are 0.67 and 0.66, respectively for BC and K-F1. Meanwhile, the flock efficiency index (FEI) that calculated as FEI = FP/ewe weight0.75 for the respective genotypes are 1.57 and 1.54 for BC and K-F1. The estimates of repeatability of litter weight at weaning show relatively low value (0,092), therefore the estimate of MPPA (Most Probable Producing Ability) for predicting the future productivity is relatively the same. The estimate of MPPA for litter weight at weaning (LWW) for the respective genotype are 11.79 and 11.81 kg, respectively for BC and K-F1. Results of the study show that performances of composite genotypes (F) and the contemporary crossbred (BC) are relatively similar in the traits of growth, dam productivity and the estimate of MPPA.

Morphological characterization of Madura cattle in Madura islands was done as an input for "action plans" of national animals genetic resources management according to the global system ofFAO. Assessments were done in Sumenep District and Pamekasan District, East Java. According to the body measurements, Madura cattle can be classified as a small to medium type with withers height of about 120 cm. Because of potential productivity in the limitation of environmental resources, Madura cattle can be classified as a "superior" cattle . Body measurements of Madura cattle in the present study were relatively the same with those of 50 years ago, indicating that there is no breeding improvement activities except natural selection . The variability of body measurements is relatively narrow . Improving productivity by outbreeding is needed . To conserve the unique germ plasm of the Indonesian genotype, such as Madura cattle and a possibility to improve their productivity by a complete prevention of cross breeding in the Madura islands needs further evaluation . Keywords: Madura cattle, morphological characteristic, conservation

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 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 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.
