“…Hossein Ghasemi et al (2014), similarly, observed an increased BWG with an improved FCR by supplementing synbiotic up to 0.1% in diets of broiler. Hassan Abdel-Hafeez et al (2017) reported 1.4% increased FI, 4.8% better BWG and 3.5% improved FCR by dietary supplementation of 0.1% synbiotic compared to probiotic supplemented diet in broilers. Nihar Ranjan et al (2016), in contrast, reported that supplementation of synbiotic at 0.05% to 0.2% did not affect growth performance (FI, BWG, and FCR) in broilers.…”

The aim of present study was to determine the effects of supplementation of either synbiotic or probiotic on growth performance and carcass characteristics, gut health, cecal microbiota prolife and apparent ileal digestibility of protein, amino acids, and energy in broilers. Two hundred and forty-day-old straight-run broilers (Ross 308) were allotted randomly to 1 of 5 dietary treatments including basal diet (control), supplemented with either synbiotic (Nutromax P) or probiotic (Actera), each at 0.5 and 1 g/kg of the diet for 5 weeks. The overall findings of the study indicated better (p < 0.05) growth performance of broilers by synbiotic supplementation (1 g/kg) compared with those fed probiotic (1 g/kg) supplemented and control diets. The broilers consuming diet supplemented with 1 g/kg synbiotic has an increased carcass yield in comparison with those fed control diet. The findings of gut health indicated significantly increased villus height and goblet cells, by synbiotic supplementation (1 g/kg), compared with control diet in broilers. The broilers fed 1 g/kg synbiotic supplemented diets had 18% increased protein, 9 to 31% higher amino acid, and 34% better energy digestibility, whereas 8.4% decreased protein digestibility in broilers fed probiotic (1 g/kg) supplemented compared with control diet in broilers. The broilers fed synbiotic (1 g/kg) supplemented diets had increased cecal Lactobacillus and decreased Salmonella, E. coli, and Clostridium count compared with those fed control diet. In conclusion, synbiotic supplementation (1 g/kg) resulted in improved production performance, balanced cecal microbial composition, and better digestibility of nutrients in broilers compared with those fed control and diets supplemented with probiotics.

“…Energy and CP levels are key factors in determining the body composition of chickens [ 109 ]. The low- and high-energy levels of broiler diets can decrease and increase fat accumulation, respectively [ 110 , 111 ]. In contrast, a previous study by Lipiński et al [ 112 ] reported that low-energy diets (−23.9 vs. −59.75 kcal/kg from the control feed) increased fat accumulation in the breast muscles, potentially as a defensive mechanism to cope with energy deficiency, while low energy diets reduced MDA concentrations in the breast meat.…”

Poultry meat is becoming one of the most important animal protein sources for human beings in terms of health benefits, cost, and production efficiency. Effective genetic selection and nutritional programs have dramatically increased meat yield and broiler production efficiency. However, modern practices in broiler production result in unfavorable meat quality and body composition due to a diverse range of challenging conditions, including bacterial and parasitic infection, heat stress, and the consumption of mycotoxin and oxidized oils. Numerous studies have demonstrated that appropriate nutritional interventions have improved the meat quality and body composition of broiler chickens. Modulating nutritional composition [e.g., energy and crude protein (CP) levels] and amino acids (AA) levels has altered the meat quality and body composition of broiler chickens. The supplementation of bioactive compounds, such as vitamins, probiotics, prebiotics, exogenous enzymes, plant polyphenol compounds, and organic acids, has improved meat quality and changed the body composition of broiler chickens.

“…Dietary ME and CP levels are two most important factors affecting meat quality. Low dietary ME reduced abdominal fat of broilers ( Fan et al, 2008 ; Abdel-Hafeez et al, 2016 ) and improved tenderness. Increasing CP levels significantly reduced content of abdominal fat, carcass, and breast and leg muscles, and increased pectoral CP content in broiler ( Marcu et al, 2013 ), affecting the quality indicators ( Jlali et al, 2012 ).…”
