This study was undertaken to determine the performance of broiler chickens given tamarind pulp extract (TP), oxytetracycline and citric acid in drinking water. One hundred and twenty, two week old broilers were divided into four treatment groups replicated four times in a completely randomized design. The control group (CON) was given tap water with no additive while the other groups TP, AB and CA received 30g/L tamrind pulp extract, 2g/L oxytetracycline and 2g/L citric acid in drinking water respectively. Feed and water were provided ad libitum throughout the six weeks experimental period. Average weight gain, feed consumption, feed efficiency and carcass parameters were used as criteria of response. Results showed that average feed intake was lower (P<0.05) in the groups offered TP and citric acid while the group on antibiotic ate the most (P<0.05) compared to the control group. The final body weight and body weight gain were also affected (P<0.05) by treatment. The mean slaughter weight, carcass weight, dressing percentage and cut-up parts of the four treatments were significantly affected (P<0.05) by treatment. It was concluded that tamarind pulp extract (30g/L) and citric acid (2g/L) offered via drinking water to broiler chicks can be used as replacements for antibiotic growth enhancers because of their positive effect on growth and carcass parameters.
