This study was carried out to determine the effects of Prebiotic, Probiotic and
Synbiotic in diets on broiler growth performance, carcass measurements, blood
picture, serum glucose, calcium and phosphorus levels, liver function, and economical
evaluation. Five hundred Sasso chicks (1-day-old) were used. The dietary treatments
were as follow: basal diet (control); Basal diet plus 0.5 kg of probiotic Lactic dry®/ton
of the feed; basal diet plus 1 kg of prebiotic Bio-MOS®/ton feed; and basal diet plus 0.5
kg of Lactic dry® and 1 kg Bio-MOS®/ton feed, respectively. Dietary supplementation
of probiotic, prebiotic and synbiotic (probiotic with prebiotic) improved body weight
gain, feed conversion ratio and breast muscle percentage. However, they did not affect
liver enzymes. The prebiotic and synbiotic supplementation caused statistically
significant increase in the erythrocyte count, hemoglobin concentration and
haematocrit values comparatively with control values. Glucose, cholesterol, LDL, and
Triglycerides concentrations showed significant decrease. Significant increase was
recorded in calcium levels in prebiotic and symbiotic groups. Economical efficiency of
the feed additives was improved. The results of the present study showed that
synbiotic provide additive benefits in growth performance, feed conversion ratio,
hematological and biochemical parameters than that of individual use of these
additives.
