This study was conducted to investigate the effects of dietary supplementation with manganese hydroxychloride (MHC) on production performance, antioxidant capacity, tibial quality, and manganese (Mn) deposition of broilers. A total of 756 one-day-old male Arbor Acres broilers were randomly allotted to 7 treatments of 6 replicates with 18 broilers per replicate. Broilers were fed corn-soybean meal basal diets supplemented of 100 mg/kg Mn as Mn sulfate (MnSO4), or 0, 20, 40, 60, 80, 100 mg/kg Mn as MHC for 42 days. The growth performance of broilers was not affected by dietary MnSO4 or MHC (p > 0.05), whereas the dressing percentage increased linearly (p < 0.05) with increasing of dietary MHC addition level. The activities of catalase (CAT) and manganese superoxide dismutase (MnSOD), and total antioxidant capability (T-AOC) in serum and liver on day 42 increased linearly (p < 0.05) with increasing of dietary MHC level, while malondialdehyde (MDA) concentration reduced linearly (p < 0.05). The length, strength, and density index of tibia increased linearly (p < 0.05) on day 21 as MHC supplementation level increased; there were no differences between MnSO4 group and 40–100 mg/kg Mn as MHC groups in tibial parameters of broilers (p > 0.05). As supplemental MHC levels increased, the Mn contents in heart, liver, kidney, and tibia increased linearly on day 42 (p < 0.05). In summary, dietary supplementation with MHC improved antioxidant capacity, bone quality, and Mn contents in broilers, but no effects on growth performance were detected. Based on the results of this study, dietary inclusion of 50–90 mg/kg Mn in the form of MHC to broilers is recommended.

Abstract This study was carried out to analyse the growth performance, feed utilization, and antioxidant capacity of juvenile mud crab (Scylla paramamosain) reared in two conditions. Here, a new indoor polypropylene tank culture system and a traditional outdoor pond cage facility were used to perform feeding experiments on juvenile crabs. After eight weeks, the survival rate, weight gain, moulting rate and feed efficiency of crabs cultured in polypropylene tanks were markedly higher than those cultured in pond cages. Moreover, the activities of serum acid phosphatase (ACP) and alkaline phosphatase (ALP), and the antioxidant indices including glutathione peroxidase (GSH-PX), glutathione transferase (GST), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) in hepatopancreas were higher in crabs cultured in the polypropylene tank system than those in pond cages. Based on these results, compared with the traditional pond cages, the polypropylene tank culture system is more suitable for the short-term culture of mud crabs.

Abstract Glucan has been studied as a potential alternative to antibiotics for animals in recent years. The aim of this study was to evaluate the effect of dietary glucan on growth performance and gut health of weaning piglets, which is a water-soluble extracellular ꞵ-glucan produced by Agrobacterium sp. ZX09. A total of 108 weaned piglets (21 d of age; 6.05 ± 0.36 kg) were randomly assigned (6 pens/diet; 18 piglets/pen) to 3 dietary treatments consisting of a basal diet (control group) or the basal diet supplemented with 20 ppm olaquindox or 200 ppm glucan for 14 days, respectively. The results showed that piglets fed with glucan had greater (P &lt; 0.05) body weight and average daily gain than piglets in control group. Piglets fed with glucan or antibiotic had greater villus height to crypt depth ratio on duodenum compared with control group (P &lt; 0.05). The mRNA expression of Claudin-1 on duodenum or ileum was higher (P &lt; 0.05) in glucan group than that on the other groups. The mRNA expression of TLR4, MYD88 and NFκB on jejunum were lower (P &lt; 0.05) in glucan or antibiotic group than those in control group. Dietary supplementation with glucan tended to increase the IL-10 and SIgA concentration on ileum (0.05 &lt; P &lt; 0.1). Dietary supplementation with glucan tended to increase the total antioxidant capacity on jejunum (P = 0.093). In conclusion, 200 ppm glucan or 20 ppm olaquindox can improve the growth performance of weaning piglets. The glucan may can accelerate the growth of weaned piglets by improving gut health. This research will provide guidance for the olaquindox alternative on growing piglets.
