| dc.description.abstract | The study involved 90 Cobb straight run broiler chicks randomly assigned to Control (45 birds) and Treatment 1 (45 birds) with 15 birds per replicate to determine the effects of dietary probiotics on the growth performance under conventional housing. The specifically, this study aimed to a.) evaluate the growth performance of broilers fed with and without probiotics; b.) compare the carcass yield and gut morphology (abdominal fat weight, abdominal fat percentage, liver weight, intestinal weight and intestinal length) of broilers fed with and without probiotics; and c.) compare the economic benefit of broilers fed with and without probiotics. Treatment description were namely: SD (Standard Diet) and SD + Dietary Probiotic at 200g/100kg. The experiment was conducted for 35 days. The results showed a significant improvement (p<0.05) in feed intake and feed conversion ratio. The gut morphology examination showed that probiotics had beneficial effect on dietary probiotics causing a significant increase on liver weight compared to fed without probiotics. Further study is needed to find the optimum application of such additives including their optimum dosage level in the feed in order to obtain maximum effects. | |
