Effect of Dietary Probiotic, Prebiotic and Synbiotic Supplementations on Growth Performance, Carcass Traits and Serum Lipid Profile in Broiler Chicken

Abstract

Probiotics, prebiotics, and synbiotics are either microorganisms or substrates that facilitate beneficial microorganisms' growth. These compounds can be supplemented with the diets to modulate the various functions of the body. This study was conducted to evaluate the dietary effect of probiotic, prebiotic and synbiotic supplementation on growth and meat quality parameters of broiler chicken. One-hundred ninety-two, day-old broiler chicks were assigned into four treatments in a completely randomized design with four replicates. Basal feed, basal feed supplement with prebiotic, probiotic and synbiotic were used as treatments. Growth parameters, blood serum parameters, meat quality, abdominal fat deposition and cecum bacterial counts were measured. Data were analyzed using the MixedAnalysis of Variance in SAS. Feed conversion ratio, total feed intake, blood serum and meat quality parameters and bacterial counts in the cecum were not differed significantly (p>0.05). The abdominal fat content was significantly lower (p<0.05) in the probiotic-fed group. This study revealed that supplementation of probiotic, prebiotic and synbiotic to broiler diet did not cause any significant change in growth performance, meat quality, and blood serum parameters. Feeding probiotics incorporated basal feed is a better solution to reduce fat deposition without interfering with broiler chicken's growth performances at a lower cost.
