24:T501,The study investigated the effects of dietary zeolite supplementation as an antibiotic alternative on growth performance, intestinal integrity, and cecal antibiotic resistance genes abundances of broilers. One-day-old chicks were assigned into three groups and fed a basal diet or a basal diet supplemented with antibiotics (50 mg/kg) or zeolite (10 g/kg). Antibiotic or zeolite increased (p < 0.05) average daily gain (ADG) from 1 to 42 days and duodenal villus height to crypt depth ratio (VH:CD) at 21 days. Zeolite increased (p < 0.05) ADG and average daily feed intake from 1 to 21 days, jejunal VH:CD at 21 and 42 days, ileal VH and VH:CD at 42 days, zonula occludens-1 mRNA abundance at 21 days, and duodenal occludin mRNA abundance at 42 days, whereas reduced (p < 0.05) jejunal CD and malondialdehyde levels in ileum at 21 days and duodenum at 42 days, serum D-lactic acid and diamine oxidase levels at 42 days, and plasma lipopolysaccharide content at 21 and 42 days. Antibiotics reduced (p < 0.05) duodenal claudin-2 mRNA abundance at 21 days, whereas increased (p < 0.05) cecal tetB abundance at 42 days. These findings suggested that the beneficial effects of zeolite in broilers were more pronounced than that of antibiotics.25:T50f,This experiment aimed to evaluate the effects of incorporating a synbiotic into diet on growth performance, lipid metabolism, antioxidant status, and meat quality in Partridge shank chickens. A total of 128 1-day-old male Partridge shank chicks were randomly divided into 2 groups, and each group consisted of 8 replicates with 8 birds each. Birds in the 2 treatments were fed a basal diet supplemented with or without 1.5 g of a synbiotic per kg of feed consisting of prebiotics (xylooligosaccharide and yeast cell wall) and probiotics (Bacillus licheniformis, Bacillus subtilis, and Clostridium butyricum) for 50 days. Compared with control group, supplementation with synbiotic significantly decreased feed to gain ratio during days 1–21, absolute and relative abdominal fat weight, and hepatic malondialdehyde concentration as well as plasma triglyceride concentration at 50 days of age. In addition, dietary supplemented with synbiotic had lower 24-h postmortem drip loss, cooking loss of breast muscle, whereas higher plasma high density lipoprotein cholesterol level, 24-h postmortem redness, and pH of breast muscle. Dietary synbiotic supplement could promote growth performance, regulate lipid metabolism, and improve antioxidant capacity and meat quality in Partridge shank chickens.
