This study aimed to examine the effects of supplementation of different legume leaves on feed intake, digestibility and daily liveweight gain of goats given Mulato grass as the basal diet. Twenty four male Kacang goats of approximately seven months old with initial body weight of 15.85 ± 0.56 （SE） kg were used. The experiment was a randomized block design with four treatments, and each treatment was replicated six times. The goats were randomly distributed into six groups according to their initial body weight rank. The dietary treatments tested were： TI： Mulato grass ad libitum （M）, T2： M ＋ Desmantus pernambucanus leaves （1.5% of body weight/day） （MD）, T3： M ＋ Gliricidia sepium leaves （1.5% of body weight/day） （MG）, and T4： M ＋ Leucaena leucocephala leaves （1.5% of body weight/day） （ML）. The animals were confined in individual metabolic crates during the study, which consisted of two weeks adaptation period and eight weeks measurement period. Parameters measured were feed dry matter intake （DMI）, dry matter digestibility （DMD）, estimated metabolisable energy intake （MEI）, metabolisable energy retention （MER） and daily liveweight gain （DLG）. Results showed that supplementation with different legume leaves to the goats receiving Mulato grass significantly increased （P 〈 0.05） total DMI, DMD, MEI, MER and DLG of the animals. Total DMI for goats treated with TI, T2, T3 and T4 were 3.61%, 3.85%, 3.98% and 3.89% of body weight/day, respectively. Feed DMD for the four treatments were 57.68%, 63.66%, 65.74% and 64.81% for T1, T2, T3 and T4, respectively. DLG were 51.98, 69.84, 84.92 and 75.40 g/day for goats treated with T1, T2, T3 and T4, respectively. It was concluded that supplementation of legume leaves to Kacang goats fed Mulato grass significantly increased feed DMI, DMD and the animals＇ DLG, but there were no significant differeces among the legume leaves as feed supplements.展开更多

This study was done to examine the effect of addition of Gliricidia （Gliricidia sepium） leaf or rice bran on feed intake, feed digestibility and liveweight gain of Kacang goat given Mulato （Brachiaria mulato） grass. Twenty four male Kacang goat, approximately 13.4±0.6 kg in initial weight and 10 months of age, were housed in individual metabolic pen and allocated to one of three dietary treatments. The experimental design was a completely randomized block design, with three treatments and eight replicates （goats）. The treatments were Mulato grass ad libitum （M）, Mulato ＋ Gliricidia （1% weight/d on dry matter basis） （MG）, and Mulato ＋ rice bran （1% weight/d on dry matter basis） （MR）. The experiment was run for eight weeks period （two weeks for adaptation and and six weeks for measurement period, respectively）. Parameters measured were liveweight gain （LWG）, dry matter intake （DMI） and dry matter digestibility （DMD）. The result showed that dietary treatment significantly （P 〈 0.05） affected the LWG, DMI and DMD of Kacang goat. Goat given Mulato grass had the lowest LWG, DMI and DMD with value 58 g/d, 2.77% weight/d and 57.61%, respectively. Goat received Mulato ＋ Gliricidia and Mulato ＋ rice bran had a significant higher LWG （73 g/d and 76 g/d, respectively）, DMI （3.25% weight/d and 3.65% weight/d, respectively） and DMD （62.28% and 63.19%, respectively）. However, no significant difference （P 〉 0.05） between goat received Mulato ＋ Gliricidia and Mulato ＋ rice bran. In conclusion, this study demonstrated that protein or energy contents of the diet influenced growth, feed intake and digestibility of Kacang goat.展开更多
