The purpose of this research was to examine the carcass quality and meat quality of native chicken fed dried tomato meal in diet. The study was conducted by using 200 heads of native chickens 10 days. The birds were divided into five experimental diets and each was divided into four replicate groups of ten birds per replicate. The based diet was formulated to contain 42% corn, rice bran 9%, fish meal 10%, fish oil 5%, soybean meal 9% and commercial diets 25%. Tomato meal was included in five experimental diets at levels of 0, 3, 6, 9, 12% to substitute based diets. The treatments were PO = 100% based diet (BD) + 0% tomato meal (TM); P1 = 97% BD+ 3% TM; P2 = 94% BD + 6% TM;P3 = 91% BD + 9% TM; P4 = 88% BD + 12% TM. Chemical composition of tomato meal was: 20.73% crude protein, 1.53% fat, 30.94%crude fiber, 0.98% Ca, 1.20% P and 2,416 kcal/kg of Gross Energy (GE). Results showedthat feeding tomato meal at an inclusion rate of 12% increased slaughter weight, carcass, breast meat, wings, drumstick and thigh, and decreased abdominal fat and blood cholesterol. Moreover, there were no significant difference in giblet (liver, heart and gizzard) between treatments. Meat water and meat crude protein were significantly increased. Meat crude fat and meat cholesterol were significantly decreased. In conclusion, tomato meal can be used as an alternative feedstuff in kampong chicken diets at inclusion levels up to 12% without negative effects on carcass quality and meat quality.

This study was conducted to investigate the effect of different level of energy and crude fiber in diets containing sawdust on carcass quality of broilers. A total of 120 broilers were used for the research. The experiment utilized a completely randomized design in 2 x 3 factorial arrangement of treatments consisting of two dietary concentrations of energy and three dietary concentrations of crude fiber. Each treatment consisted of 4 replications (5 birds each) was reared during 35 days. The birds were housed in battery cages with ad libitum access to feed and water. During the experiment, feed intake, carcass yield, abdominal fat, blood LDL-cholesterol and HDL-cholesterol were measured. Data were subjected to the analysis of variance test followed by least significant difference test (LSD). Results showed that the diet with 3,100 Kcal/kg ME and 11% crude fiber significantly decreased feed intake, abdominal fat percentage, and blood LDL-cholesterol, but did not affect final body weight and the value of blood HDL-cholesterol and had the good value of carcass percentage. The diets containing sawdust with higher level of energy content decreased feed intake and the higher level of crude fiber decreased final body weight, carcass percentage and abdominal fat. Optimum broiler performance and carcass quality was obtained by diet formulated to contain 3100 Kcal/kg ME and 11% crude fiber.

The study was conducted to evaluate the effect of level of banana (Musa paradisiaca) leaves fermented with Trichoderma viride at different days on the carcass yield of broiler chickens. A hundred and eighty 3-weeks-old broiler chicks were used in this present experiment based on factorial design (3×4). The birds were randomly allocated into three experimental diets containing of 5, 10 and 15% of banana leaves fermented within 0, 5, 10 and 15 days. Each treatment was divided into three replicates of five chicks in each. The experiment was terminated after 4 weeks or when the birds were 7-weeks-old. Feed intake, body weight gain, feed efficiency and carcass yield were measured during the study. The data were subjected to the analysis of variance test followed by least significant difference (LSD) test. Results showed that daily feed intake was significantly affected (P˂0.01) by the dietary treatments, in which feed intake was highest in broilers fed diet containing 10% banana leaves fermented for 10 days. The daily weight gain, feed efficiency and carcass yield were significantly affected (P˂0.01) by the treatments, in which the highest values of daily weight gain, feed efficiency, and carcass yield were observed in birds fed diet containing 10% banana leaves fermented for 10 days. It can be concluded that diet containing 10% banana leaves fermented for 10 days can be included in broiler ration without detrimental effects on the performance and carcass yield.
