Abstract
The aim of this study was to determine the effects of feed additives for broilers which are used alone or in combination to induce productivity (Probiotic, oligosaccharides, organic acid and avilamycin) on body weight, feed intake, feed conversion ratio, mortality rate and uniformity. Daily chicken (n=900) were randomly divided into nine groups. Group I was seperated from the others as a control group. The chickens in this group was fed with corn soya bean till end of study. The other groups had fed with corn soya bean and food additives described below; probiotic (% 0.05), oligosaccharides (mannanoligosachcaride=MOS) (% 0.01), organic acid (% 0.15), probiotic (% 0.05) + oligosaccharides (% 0.1), probiotic (% 0.05) + organic acid (% 0.15), oligosaccharides (% 0.1) + organic acid (% 0.15), avilamycin (% 0.1), probiotic (% 0.05) + oligosaccharides (% 0.1) + organic acid (% 0.15), respectively. Body weight and feed intake parametres were controlled weekly and mortality rate was followed up daily. Broilers had been fed till 44 days of age. At the end of the study, there was no significant mortality rate differences among the groups, body weight and feed conversion ratio was higher in probiotic + oligosaccharides + organic acid group. On the other hand, using probiotic and oligosaccharides alone has no important effect on feed intake and feed conversion, although they were more effective than control group till day 21, however they had no effect after day 28. When organic acids were used alone they were less efective then avilamycin; however, using of organic acid was more efective than control group on body weight, feed conversion and feed intake parametres. Probiotic + oligosaccharides, probiotic + organic acid and oligosaccharides + organic acid mixtures provided better results than control group, however they were less effective than the antibiotic and triple mixture. It can be concluded that, these products have positive effects to increase the effect of the each others, growing performance and feed conversion. This result shows using of probiotics, oligosaccharides and organic acid mixture can be a good alternative in the countries antibiotic-banned
