Abstract
To meet the increasing demand of consumers on poultry products, poultry feed does not only improve the growth performance but also enhance meat quality. By this reason, the study was to evaluate the effects of pineapple leaf powder on growth performance and carcass characteristics of Noi broiler chickens from 5-12 weeks of age. The study was conducted at Tra Vinh University – experimental farm involving with 120 Noi crossbred broilers from 4 weeks of age. The study was a completely randomized design with 04 treatment and 03 replicates, consisting of 0% (control treatment, T0), 0.1% (treatment 1), 0.3% (treatment 2) and 0.5% (treatment 3) of pineapple leaf powder in the diet. Birds were fed ad libitum throughout the experiment. The results showed that body weight (1603 g/bird at 12 weeks of age), daily weight gain (21.90 g/bird/day) had the highest performance while feed intake (55.28 g/bird at treatment 2) and feed conversion ration (2.610) showed the lowest performance in the treatment 3 (P<0.05). However, the study did not record any significant changes in carcass traits, pH and cooking loss of broiler meat between treatments (P>0.05). It can be concluded that the inclusive of pineapple leaf powder on diets could improve growth rate of Noi crossbred chickens from 5-12 weeks of age.
