Effect of dietary mannan-oligosaccharides from copra meal on intestinal microbes and blood profile of broiler chickens
Abstract: Mannan-oligosaccharides
(MOS) is a common prebiotics used as a feed additives. The use of antibiotic
can be replaced by MOS to reduce the number of pathogenic bacteria in small
intestines of chickens. The objective of this study was to determine the effect
of MOS extracted from copra meal on intestinal microbial population and blood
profile of broiler chickens. The study was conducted by using 150 day-old male
broiler chickens (average body weight 46.00 +
1.41 g). The design of this experiment was a completely randomized
design (CRD) with 3 dietary treatments, 5 replications and 10 birds in each
replication. The dietary treatments consisted of control diet (corn-soybean
meal diet without supplementation of antibiotic and prebiotic), control + 0.1%
antibiotic bambermycin, and control + 0.035% MOS. For the first 4 weeks the
birds were fed treatment diets, followed by commercial feed for 2 weeks. The
parameters observed in this study were intestinal microbes population and blood
profiles. The results showed that the administration of 0,035% MOS increased
the lactic acid bacteria (LAB) number compared with antibiotics feed
(P<0.05), but not significantly different (P >0.05) with the control
group. The total aerobic and coliform bacteria were higher in MOS and
antibiotic treatment compared than control group. The supplementation of 0.035%
MOS from copra meal in diet increased the level of leucocytes which is
important to immune response of broilers and its usage was safe because the
level of chicken blood profile were within the normal range.
