GROWTH PERFORMANCE AND CARCASS CHARACTERISTICS OF BROILER CHICKENS FED DIET SUPPLEMENTED WITH ORGANIC TRACE MINERAL BLENDS
Abstract
The experiment was conducted to evaluate the growth performance and carcass characteristics of broiler chickens fed diet with supplemented organic trace mineral blends. A total number of one hundred and twenty (120) day old broiler chicks were randomly distributed into four (4) dietary treatments with three (3) replicate of ten (10) birds per each replicate. Treatment 1 (T1) was the control diet, while Treatment 2 (T2) was supplementation of organic trace mineral blends at 50% lower than the manufacturer’s recommendation, Treatment (T3) was supplementation of organic trace mineral blends at the normal recommendation of the manufacturer and Treatment 4 (T4) was the supplementation of organic trace mineral at 50% higher than the manufacturer’s recommended level in a completely randomized design. Data were collected on daily feed intake, weight gain and feed conversion ratio on weekly basis. There is significant difference (P>0.05) in final body weight, Total weight gain and feed conversion ratio. Result obtained from the growth performance showed that the group of chicken fed on control diets had the highest value for final body weight of (2015.00g) and lowest value was recorded for (T4) (1962.00g). The highest total weight was recorded for (T3) supplementation manufacture’s recommendation level (1440.00g). Birds fed on (T3) had the lowest feed conversion ratio (1.83) compared to other groups which implies the better utilization of the mineral. . No mortality was recorded. Based on the result of this study, it can be concluded that the use of supplementation of organic trace mineral blends at manufacturer’s recommendation is effective in promoting growth performance of broiler chicken, Result obtained from the carcass characteristics showed that there is no significant difference among all parameters, organic trace mineral can be supplemented to broiler chicken since it have no negative effect on birds.
