An experiment was carried out for 12 weeks to study the feeding behaviour, growth and carcass characteristics of cross-bred goats. Nine bucks with an average live weight of $18.02{\pm}0.9kg$ were allocated in a completely randomized block design arrangement, consisting of three feeding regimes and three blocks. The feeding regimes consisted of 100% natural grass (Treatment A), 100% gliricidia leaf (Treatment B) and 100% ficus leaf (Treatment C). Frequency of turning-over and sniffing the feed and duration and frequency of ruminating, defaecating, and urination of goats in treatment B were longer, while duration of masticating and jaw movement of chewing one bolus was shorter than those of goats in treatments C and A (p < 0.05). Furthermore, goats in treatment B gained more live weight, consumed more feed, consumed less water and was more efficient in utilizing the feed than goats in treatments C or A (p < 0.05). The dressing percentage, carcass length and carcass fat of goats in treatment B were higher and their bone percentages were lower than those in treatments C and A (p < 0.05). There is an indication that feeding gliricidia and ficus leaves during the dry season could not only increase the body weight and improve carcass quality of the goat but also save water for household needs.

문제 정의
The objective of this experiment was to study the effect of either grass, shrub legume or tree fodders diet on the feeding behaviour, growth and carcass characteristics of cross-bred male goats during the dry season in Bali, Indonesia.
제안 방법
The completely randomized block design arrangement consisted of three feeding regimes (treatments), three blocks (replicates) and one goat for each treatment. The feeding regime consisted of 100% natural grass (Treatment A), 100% gliricidia leaves (Treatment B) and 100% ficus leaves (Treatment C).
The behaviour study was carried out for 10 hours (07:00 to 17:00) for nine days. The observations were frequency of turning-over and sniffing the feeds, duration and frequency of eating the feeds, duration and frequency of ruminating, number and duration of bolus mastication, jaw movement in masticating one bolus, duration and frequency of defaecating, duration and frequency of urinating and duration and frequency of resting. Each observation was repeated three times and then pooled so that the average represented one replication.
대상 데이터
Nineteen cross-bred bucks (75% Kacang and 25% Etawah breeds) were bought from a traditional goat farm at Tangkas, and transported by truck to the experimental site. They were accustomed to the conditions in the shed for 14 days.
데이터처리
Data were analyzed with analysis of variance and the significance of differences between treatment means (+p < 0.10; *p < 0.05) was assessed by the Duncan's multiple range test (Steel and Tome, I960).
