Abstract
This study investigated the effects of probiotics and synbiotics on the growth performance, carcass characteristics, and the performance of meat quality attributes in broilers. Total of 210 Ross-308 chicks of broilers were allocated randomly seven groups with 3 replicates and ten chicks per replicate. The dietary interventions included: basal diet (Control) T0, Basal diets including with three levels of probiotics and the probiotics dose rate were 1g, 1.5g and 2g/kg of feed respectively to T1, T2, T3 groups broiler starter and grower phase, basal diets with three levels of synbiotic and the synbiotic dose rate were 1g, 1.5g and 2g/kg of feed respectively to T4, T5, T6 groups in broiler starter and grower. In comparison between the control group and the broilers fed probiotics and synbiotic diet showed a substantial (P<0.05) increase in body weight, body weight growth, and carcass yield percentage. In comparison to the other treatment groups, dietary inclusion of probiotics and synbiotic dosage measure of 2g/kg in feed was responsible for higher feed intake, body growth and carcass yield. The treatment group that was given synbiotic supplements had a very low feed conversion ratio (FCR). The findings about the quality of meat showed that the treatment of probiotics and synbiotic changed significantly PH readings from the collections of the control group. The results of the current study showed that type of synbiotic, which are used to optimize growth in broilers, optimize digestion and convert feed more efficiently to body mass.
