Title: Effect Of Dietary Levels Of Spearmint (Mentha Spicata) On Broiler Chicks Performance
Author: Mahala, Ahmed
Abstract: This study was conducted to determine the effect of addition different levels of spearmint (Mentha spicata) on broiler chick’s performance. One hundred and twenty eight day old unsexed (Cobb) broiler chicks were used in this experiment. Birds were distributed randomly into 16 pens (8/pen) as replicates, in a complete randomized design. The experimental diets were formulated with four levels of spearmint (Mentha spicata) of 0, 1, 1.5 and 2%. Feed and water were freely accessed. Feed intake, body weight gain and feed conversion ratio were weekly recorded and Mortality rate was recorded throughout the experiment. At the end of the experimental period, four birds from each treatment were randomly selected, weighed and slaughtered for determination of carcass weight and dressing percentage. Average feed intakes obtained from the experiment were 2680.20, 2679.11, 2708.55 and 2692.57 for diets 0, 1, 1.5%and 2%, respectively. However, the body weight gains for the treatments were 1481.63, 1512.81, 1519.57 and 1519.63, 0, 1, 1.5 and 2, respectively. Feed conversion ratios for treatments were found to be 1.92, 1.94, 1.92 and 1.99 respectively. Dressing percentage were 73.12, 74.17, 73.08 and73.47 respectively. The results indicated that the supplementation of different levels of spearmint to the diets of broiler improved feed intake and body weight gain.
