Abstract
Thai native chickens (Chee-Long Yasothorn) are resistant to local environmental conditions and can eat locally sourced feed such as Cayenne leaf meal,which is nutritious and can be expected to have a positive effect on raising chickens. Therefore, the effect of dietary Cayenne leaf meal (Cnidoscolus aconitifolius) on productive performance and consumer acceptance of Thai native chicken (Chee-Long Yasothorn) meat quality was studied. The first experiment used Cayenne leaf meal in 0, 5, 10, and 15% mixed with chicken feed. One hundred and sixty-one-day-old mixed-sex chicks were allocated into the experiment using a completely randomized design with four repetitions of 10 chicks each. Chicken production performance data was collected until the age of 12 weeks. The second experiment assessed chicken meat quality by panel testing. Sixteen consumers used a balanced randomized incomplete block design. The data were analyzed for variance to determine the P<.05 value. It was found that the amount of feed consumed, number of chickens, cost of chicks, tenderness, toughness, aroma, fineness of muscle fibers, and palatability did not show statistically significant differences (P>.05). While using 15% Cayenne leaf meal mixed with chicken feed, it increased chicken weight. Feed conversion rate, cost of feed, cost of raising chicken, chicken selling price, profit or loss, carcass weight, chicken meat color, juiciness, taste (P<.01), carcass percentage, and consumer acceptance (P<.05) were the highest. Therefore, 15% Cayenne leaf meal mixed with chicken feed increased growth performance, yield, and consumer acceptance of chicken meat quality, which was the highest with the lowest feed cost.
