The characterization is main activities in order to identify important trait of Katingan cattle. Information of its phenotypic characteristic is not available yet. The aim of the study is to describe the qualitative characteristic of Katingan cattle. Three location of the study were sub-district of Tewah Sanggalang Garing (Pendahara Village), sub-district of Pulau Malan (Buntut Bali Village), and sub-district of Katingan Tengah (Tumbang Lahang Village). The samples of Katingan cattle were taken as many as possible based on the field conditions to observe pattern of colour, growth of horn and gibbosity appear among two horns. General characteristic of Katingan cattle was various in colours of coat, having horns, humped and dewlop. The main characteristics were expressed at female of Katingan cattle. There were six variations of horn shape at female, however the growth of arching forwards was dominant (78.4%). Horn shape of male was generally grown upside (98.3%). Gibbosity was founded among horn only at female cattle (92.6%). There were 9 combinations of coat colour of female Katingan Cattle, those were brown reddish (27%), brown whitish (14.1%), brown like colour of Bali cattle (13.8%), black (12.5%), brown dull (9.6%), brown sorrel (9.3%), blackish (7.1%), white brownish (5.5%) and white grayish (4.5%). Male of Katingan cattle had eight colour combinations, those were brown whitish (14.8%), brown whitish and reddish (14.8%), brown reddish (13.1%), blackish (12.3%), brown whiteish with black withers (10.7%), brown sorrel (9.8%) and brown sorrel with black withers (7.8%). Based on qualitative analysis, the Katingan cattle had variations in coat of colour, growth of horn and the gibbosity. The variation of coat colour had potentially selection related to the value of cultural. Key Words: Katingan Cattle, Qualitative, Coat Colour, Horn, Gibbosity

Genetic diversity is important information in the process of conservation and sustainable utilization of animal genetic resources. Thirteen microsatellite markers were used to estimate the degree of genetic diversity on five Indonesian local goats. Results showed the highest average allele diversity present in the locus MAF70 (5.6 ± 2.9), and the lowest was in the locus MAF035 (1.6 ± 0.6), the average number of alleles per locus was 6 ± 2.3. The lowest average alleles diversity present was in the Gembrong goat (2.2 ± 1.1) and the highest was in the Jawarandu goat (4.9 ± 2.2). There is a unique alleles at loci MCM527 and present in all Indonesian local goat with the highest allele frequency on Peranakan Etawa (37.2%) and lowest in Gembrong goat (7.9%). H0 ranged from 0.372 ± 0.173 (Gembrong) to 0.540 ± 0.204 (Peranakan Etawa), and HE ranging from 0.249 ± 0.196 (Gembrong) to 0.540 ± 0.212 (Peranakan Etawa).The genetic differentiation for inbreeding among population (FIS), within population (FIT), and average genetic differention (FST) were 0,0208 (2,08%), 0,1532 (15,32%), and 0,1352 (13,52%), respectively. Locus ILSTS029, BMS1494, MAF035 and INRA0132 had a low PIC value (PIC < 0.25), locus SRCRSP3, OARFCB20, ILSTS005, SPS113, MCM527, and ETH10 provide moderate (PIC = 0.25 to 0.5), and locus CSRD247, MAF70, and ILSTS11 had high value PIC > 0.5. Phylogenetic relationship was consistent with the history of its development based on Kacang goat except was for Gembrong Goat. This research information can be used for conservation strategies and breeding programs on each population of Indonesian local goat.

The study aimed to investigate the effects of offering different levels of ensiled or fresh Indigofera arrecta in completete diets on the feed consumption, ADG, ruminal fermentation characteristics and blood metabolites concentrations in growing goats. The I. arrecta/concentrate ratios of the complete diets were set at 85/100,75/100 and 65/100. Thirty weaned-male goats were used in the study, and were randomly allocated to one of the six treatments (5 heads per treatment). The diets were offered at 4% BW and the animals were weighed weekly. The study was arranged as a completed randomized design. Feed intake, average daily gain, feed efficiecy ratio, ruminal fermentation (pH, NH3 and VFA characteristics and blod metabolites (glucose and urea) were analysed. Feed intake of goats receiving ensiled Indigofera arrecta were lower (P < 0.01) compared to those receiving fresh I. arrecta. ADG were higher (P > 0.01) when goats were fed diets with lower level inclusion of Indigofera arrecta. Efficiency of feed utilization decreased (P < 0.01) when ensiled Indigofera arrecta was used in the diets, but it was not affected (P > 0.01) by the inclusion level of I. arrecta in the diets. Ruminal pH was not affected by ensiling process, but ruminal NH3 concentrations were greater (P < 0.01) in goats receiving fresh Indigofera arrecta. Ruminal VFA levels were also greater (P < 0.05) in the group offered fresh Indigofera arrecta, but the differences were not significant (P > 0.05) when diets consisted of 65% Indigofera arrecta in the complete diets. Increased rate of Indigofera arrecta inclusion in the diets resulted in lower (P < 0.01) counts of ruminal microbial population. The concentration of plasma urea nitrogen were neither affected by the ensiling process nor by the levels of I. arrecta inclusion in the diet (P > 0.05), however, the plasma glucose level decreased (P < 0.05) as the level of I. arrecta inclusion in diets increased. It is concluded that I. arrecta could be used as the sole fresh or ensiled foliage in complete diets, although the performances of goats were better when fresh I. arrecta was offered. The level of I. arrecta inclusion in complete diets was recommended at not greater than 65%. Key Words: I. arrecta, Silage, Complete Feed, Goat

The utilization of rumen undegradable protein, could increase supply of amino acids in small intestine to meet host protein requirement. To increase the utilization of feed protein, feed protein source which is highly degradable should be protected from degradation in the rumen. The objective of the study was to increase nitrogen retention through substitution of fish meal protein with soy bean meal protected by banana stem juice observed from rumen fermentation activities. The study used 18 late pregnant Sumatera Composite breed ewes. Rations consisted of fresh chopped elephant grass, supplemented with a commercial concentrate and mineral block in the form of Comin plus and different types of protein supplement as treatment diets. The type of protein supplements were: soya bean meal (RK), soy bean meal protected with banana stem juice (RKT) and fish meal (RTI). Treatment diets were offered during late pregnancy (from two months before to two months after partus), two weeks adaptation period was carried out before data recording. Design of the study used randomized complete block design. Results of the study show that rumen ammonia concentration in sheep fed on RKT was not significantly different either from RTI or from RK, however, the nitrogen retention was significantly (P < 0.05) different among the treatments (4.92 g/h vs 12.52 g/h; 17.11 g/h). Total VFA production or the proportion of C3, iC4, iC5 and nC5 was not significantly different (P > 0.05), however, proportion of C2 and nC4 was significantly different between diet treatment. Methane emission was higher (70.3 mM or 37.2% higher from total energy VFA) in diet RKT which is indicated that fermentation system was not efficient. It can be concluded the higher rumen ammonia concentration and lower nitrogen retention in protected soy bean meal supplement indicated that soy bean meal protected by banana stem juice in the ration was not able to substitute fish meal protein which is resistance from degradation in the rumen.
