Abstract
The aim of this research was to determine the effect of Caesalpinia sappan L. extract on body weight and carcass weight of bucks exposed by heat stress. This research used a completely randomized design with 4 treatments and 5 replications. The experimental animal were 5 month old bucks of rex type. The bucks were divided into 4 groups and given different treatments for 28 days, namely K + (complete feed + heat stress), K- (complete feed), P1 (complete feed + Caesalpinia sappan L. 100mg/kg feed + heat stress), and P2 (complete feed + Caesalpinia sappan L. 300 mg/kg feed + heat stress). The observed variables were the body weight and the carcass weight of the bucks. Parametric data was analyzed using ANOVA. The average body weight was K+ (2220.00), K- (2239.80), P1 (2241.60), P2 (2242.00). The average carcass weight was K+ (1132.40), K- (1232.00), P1 (1233.00), P2 (1233.20). The results of study showed that there was a significant difference (P<0.05) between the treatment and control group. Based on the research conducted, it can be concluded that the administration of Caesalpinia sappan L. extract can maintain the body weight and carcass weight of buck exposed to heat stress.
