Abstract

The effects of Tongkat Ali (Eurycoma longolia) feeding on the performance of caponized and non-caponized broiler chicken were investigated In this study. Twenty eight commercial male broiler chickens were separated into four groups which were capon without Tongkat Ali (TA) and capon with TA feeding, and non-capon without TA and non-capon with TA feeding. Each group consisted of 7 replicates. After rearing in the oil palm integration for 5 weeks, their mortality, body weight gain, meat quality and shank length were determined. Data were analyzed using chi-square and two-way ANOVA at 5% significant level. The results obtained showed that total capons (41.67%) - both TA fed and without TA feeding, had significantly lower mortality rate compared to the non-capons (61.9%). As for body weight gain, the chicken group without TA feeding was seen to have a significantly higher body weight compared to the TA fed group at all times during the rearing period of 5 weeks. As for meat quality parameter analyzed, only abdominal fat weight was significantfy lower at TA fed chickens. TA fed chickens had almost 50% lower abdominal fat content (1.06%) than that of chickens without TA feeding (2.07%). Further research needs to be done on the proper dosage of TA given to broiler chickens to Increase productivity, as well as to look Into the suitable farm management system to rear capons In the means of Increasing desired traits, such as, meat quality and body weight gain.
