| Abstract | ||
| A total of 420 Ross broiler chicks, one day old, were divided in to four treatment group were fed on standard broiler starter and finisher diets. And used as control. Chicks in T2, T3 and T4 were fed on diets supplanted with 4, 6 and 8 g/kg of locally prepared probiotic respectively. characteristics included in this experiment were: mean body weight, gain feed conversion , mortality, feed intake, dressing percentage with or without giblets, relative weight of carcass cuts, relative weight of heart, gizzard, liver, and productive index. Results revealed that the addition of probiotic to broiler diet resulted in a significant (p>0.01) increase in final body weight gain and feed conversion ratio. Also T2 recorded the best result as regards most of traits studied in this experiment. Dietary treatments were significantly improved production index and decreased mortality. No significant differences were observed in relative carcass cuts except for breast percentage which increased significantly. | ||
