外文摘要：This study was conducted to investigate the effects of dietary sodium butyrate (SB) supplementation on growth performance, liver function, antioxidant capacity, carcass characteristics, and meat quality in broilers under hot climatic conditions. A total of 288 one-day-old Arbor Acres broilers were randomly allocated to 4 dietary treatments as follow: CON, control diet without SB; T1, control diet with 300 mg/kg SB; T2, control diet with 600mg/kgSB; and T3, control diet with 1,200mg/kg SB. Each treatment had 6 replication pens and 12 broilers per pen. The results indicated that the BW on day 35; ADG from day 1 to 21, day 22 to 35, and day 1 to 35; and ADFI fromday 22 to 35 linearly (P < 0.05) increased with SB supplementation. Interestingly, alanine aminotransferase and aspartate aminotransferase content in serum were linearly (P < 0.05) decreased by SB supplementation. There was linear (P < 0.05) improvement in activity of superoxide dismutase and catalase in the liver, whereas the content of malondialdehyde was linearly (P < 0.05) decreased with the inclusion of SB. Increasing SB level linearly (P < 0.05) increased CP composition and decreased drip loss percentage on day 1 and 3 of breast muscle. Furthermore, there was linear (P < 0.05) improvement in activity of superoxide dismutase, glutathione peroxidase, and catalase, whereas the content of malondialdehyde showed decreasing trend (P < 0.10) with the inclusion ofSBin breastmuscle. In conclusion, SB can be used as an effective feed additive to improve growth performance, liver function, and meat quality of broilers under hot climatic conditions.
