Abstract

This research was conducted to study the effects of taro leaf meal in the diet on the weight percentages of carcass and viscera of broiler chicken. The reseMCh used 120 chicks which were reared for four weeks. At the end of the forth week of rearing, 24 chickens were slaughtered to be taken as samples. The diet consisted of different levels of taro leaf meal (0, 5, 10 and 15%) and formulated to isocaloric (3000 kcal/kg metabolizable energy) and isonitrogenous (22.7% crude protein) for starter period. The finisher diet consisted of 3000 kcaJ/ltg metabolizable energy and 18.7% crude protein. A Completely Randomized Design was used in this research. Pen:entage of weight of carcass, liver, heart, gizzard. spleen, pancreas and length pen:entages of small intestine and caeca were observed. The data were analyzed by Analysis of Variance/ANOVA. If significant effects were found,. comparisons among multiple means were made by . Duncan's multiple range tests. The results showed that taro leaf meal highly significant (p<O.01) affected live weight, weight percentages of carcass and liver 'IS well as the length percentages of small intestine and caeca. Pen:entage of can:all and liver and pen:entage of small intestine and caeca of the chicks fed 5% taro leaf meal were not significantly different compared to control diet (0% taro leaf meal). However, feeding S% of taro leaf meal highly significant (P<O.01) decreased the live weight. The used of 10"/0 and 15"/0 of taro leaf meal in the diet highly significant (P<O.01) decreased the live weight, weight pen:entages of can:ass and liver, and increased length percentages of small intestine and caeca compared to control (0"/0 taro leaf meal). The conclusion of this research was that the broiler chicken could tolerate lell than S% of taro leaf meal in the diet. Key words: broiler chicken, taro leaf meal, carcass, viscera.
