- Abstract
The experiment was conducted to investigate the effects of curcumin and thymol complex on growth performance, antioxidant ability and intestinal morphology of laying hens infected with Salmonella pullorum. One hundred and twenty one-day-old Roman hens were randomly divided into four groups: control group (CON), thymol-curcumin group (CT), infection group (PD) and thymolcurcumin for infection group (PD + CT), each group had three replicates of 10 chickens. CON and PD groups were fed with basal diet, CT and PD + CT groups were fed with 225 mg/kg thymolcurcumin mixture in basal diet. The chicks of each group were challenged with Salmonella pullorum at the age of 14 days. The pre-feeding period was seven days and the official experiment time was 21 days. The results were as followings: ① compared with CON group, the daily gain, feed intake and feed conversion efficiency of PD group were significantly decreased (P<0.05), while the daily gain, feed intake and feed-to-weight ratio of PD group were significantly increased (P<0.05), in PD + CT Group, the daily weight gain was significantly increased and the feed-weight ratio was significantly decreased (P<0.05). ② Compared with the CON group, while the duodenum and jejunal index of the PD group were significantly lower, and the jejunal index of the PD + CT group was significantly higher than that of the PD group (P<0.05). ③ Compared with the CON group, serum glutathione peroxidase (GSH) activity and total jejunal antioxidant capacity (T-AOC) were significantly increased in the CT group, and malondialdehyde (MDA) content in serum, liver and jejunum was significantly reduced (P<0.05). Compared with the CON group, the serum and liver GSH levels in the PD group were significantly reduced, the levels of jejunal T-AOC and t-SOD were significantly reduced, and the content of MDA in serum and liver was significantly increased (P<0.05). Compared with the PD group, the liver GSH level and jejunal T-SOD level (P<0.05) and the MDA content in the liver and jejunum were significantly reduced (P<0.05) in the PD+CT group. ④ Compared with the CON group, the height of jejunum villi, the ratio of villus to crypt and the depth of crypt in PD group were significantly decreased (P<0.05), while the height of jejunum villi, the ratio of villus to crypt and the depth of crypt in PD + CT group were significantly increased (P<0.05). In conclusion, curcumin-thymol could effectively alleviate the adverse effects of Salmonella pullorum on laying hens by improving growth performance, antioxidant capacity and intestinal morphology.
