ABSTRACT:
This research alined to determine the dry matter (DM), organic matter (OM) and crude protein (CP) degradation in sacco of various legume tree leaves from limestone and non - limestone areas in Malang. Five samples of legume tree leaves namely leucacna, calliandra, giiriciciia, sesbania and erytheina were incubated at 0,4,8.12,16,24, and 48 hours in the rumen of three fistulated fat-tail sheep (t28,4 kg live weight, the pH of the rumen fluid 6,8 and N113 3,43 niM), Those fistulatcd animals were fed the ammoniated rice straw freely (CP 11,7%, DM intake 633,1 g) and susu PAP concentrate (CP 18,3% , DM intake 26)1,0 g). The formula that has been used to calculate the DM, OM and CI\u27 degradability at the timc "t" is expressed asap = a + b (I - cc() for t_0, the similar modified formula has been used this experiment expressed that(a\u27 + b\u27) = the potential degradability of the feed, a\u27 constant = the feeds that loss during washingb\u27 constant
(a+b) a\u27c\u27 constant the degradation rate. The
result of this experiment showed that the locational factor gave a bigly significant (
