Vol. 26, No. 1, 2009Indonesian Agricultural Research Abstractsweight range from 18.23 to 23.63 kg were treated as followed T0 = napier grass ad libitum, T1 = napiergrass ad libitum + 200 g rice bran, T2 = napier grass ad libitum + 400 g rice bran. The diet given based onthe dry matter requirement for sheep was 3.6% of body weight. Data gathered on slaughter weight, carcassand non carcass, edible portion of carcass and non carcass, and total edible portion were analyzed usingANOVA for randomized block design, followed by polynomial orthogonal contrast. Result of the studyshowed that the addition of rice bran increased slaughter weight, weight and carcass percentage, noncarcass percentage, weight of edible portion carcass and non carcass, weight and total edible portionpercentage (P0.05). The average slaughter weight of T0, T1, T2 were 21,200; 25,000; and 25,980 g,respectively, while carcass weight and DP for T0 = 7,194.25 g (34.00%), T1 = 9,789.00 g (39.08%), T2 =10,148.25 g (39.04%). The average edible portion of non carcass were T0 3,430.00 g (24.67%), T1 =4,270.00 g (28.44%), and T2 = 4,678.00 g (29.95%), whereas total edible portion of T0, T1, and T2 were8,313.46 g (38.85%), 11,517.54 g (46.06%), and 12,344.76 g (47.45%). It can be concluded that theaddition of rice bran of 200 and 400 g increased edible portion of male indigenous sheep. With increasinglevel of rice bran, edible portion of carcass, non carcass and total edible portion were increased.110 PAMUNGKAS, D.In sacco feed dry matter degradability of inoculated sheep's rumen derived from rumen content ofgoat.

Four male native goats withrange of 22-35 kg live weight and four male sheep with range live weight of 25-35 kg, fitted withpermanent rumen cannula, were used. The animals were placed in individual pens during experiment andfed a diet of 70% napier grass and 30% concentrate. The amount of dry matter offered was calculated at2.5% of live weight. Feeding was done twice daily at 8.00 am and 2.00 pm. The concentrate mixtureconsisted of 60% wheat pollard, 36% copra meal, 2% urea, 1% salt and 1% calcium phosphate. Theexperiment consisted of preliminary/preparation, preinoculation, cross inoculation and postinoculationperiods. During the last three days of the first week of preinoculation, an in situ dry matter degradabilitywas conducted. The samples of feeds such as napier grass (NG), leucaena (L), and wheat pollard (WP)were incubated separately in the nylon bags were incubated for 0, 3, 6, 9, 12, 24, 48 and 72 hours in therumen of the experimental animals. During the last three days of first week of postinoculation, an in saccoDM digestibility trial similar to the preinoculation period was conducted. Changes in in sacco DMdegradability of feeds as substrates at before and after cross inoculation were determined by using t-test.Results showed that there were no significant differences in the soluble fractions (a) water insolublefraction (b), potential digestible fraction (a + b), and the rate of degradation (c) of NG before and afterinoculation. However, there was a significant increase of 8.76% (α
