Effect of Feeding Zinc Gluconate, Fructooligosaccharide and Probiotic on Broiler Body Performance

영어: This study was carried out to compare the effect of dietary zinc gluconate, fructooligosaccharide and probiotic on body weight gain, feed intake and feed efficiency of broiler chicks. A feeding trial was conducted with a total of 216 broiler chicks. Each treatment had 18 chicks with 3 replications. The supplementation levels of each treatment in the experimental diets were 0.20% for zinc gluconate, fructooligosaccharide and probiotic, respectively. The body gain of chicks fed feed additives significantly increased (p<.05) compare with that of control. Especially, the treatment with probiotic produced higher body gain than other treatments. Average feed intake of chicks was not significantly different among treatments (p<.05). Feed efficiency of chick fed feed additives significantly (p<.05) improved compare with control and the highest in the probiotic treatment. Therefore, the feed efficiency of chicks fed fructooligosaccharide, zinc gluconate and probiotic treatment were increased by 3.5%, 4.0% and 4.5%, respectively compare to that of the control. In conclusion, dietary feed additives tended to slightly improve the body gain and feed efficiency. Especially the treatment with probiotic produced higher body gain and feed efficiency among other treatments.
