PRODUCTIVE PERFORMANCE OF BROILERS (Ross 308) DIET SUPPLEMENTED WITH THYME, GARLIC AND COMBINATION.

Abstract

This experiment was conducted to investigate the effect of feeding Thyme leaves and garlic powder and combination on the productive performance of broilers. A total of 80 day-old (Ross 308) chicks were used in the experiment. Birds were partitioned into four experimental treatments (Trt) of 20 birds in each. Each treatment was composed of 2 replicates with 10 birds in each.The first and second treatments were supplemented with Thyme leaves and Garlic at the rate of 1% respectively. the third treatment was supplemented with combination of Thyme leaves and Garlic at the rate of 1% for each . the fourth treatment as control group which did not receive any thing but basal diet .The results showed that using these medicinal plants had significant effects on performance . There were high significant(p<0.05)effects among the treatments on live body weight ,weight gain, feed intake and feed conversion ratio over the entire trial. The heavest body weight and body weight gain was observed in the third Treatment and the lightest group was observed in control treatment. The highest amount of feed intake was observed in supplementary treatments but the lowest one was observed in control group . the best feed conversion ratio observed in third treatment which supplemented with combination of Thyme and garlic .In conclusion, supplementation of thyme and garlic as feed additives at levels of 1% in the present study improved productive performance of broiler chicks and we can used as alternative of antibiotics.
