This study investigated the effect of Phyllanthus emblica leaves and branches mixture (PE) on growth performance, oxidative status and intestinal characteristics in broilers, as well as the in vitro antioxidant potential of PE extract (PEE). As the result of in vitro evaluation, the PEE had a total phenolic compound content of 95.5 ± 2.75 mg of Gallic acid equivalent/g dry weight (DW), and a total flavonoid content of 3.04 ± 0.06 mg of quercetin equivalent/g DW. The PEE exhibited significant antioxidant activity through various mechanisms, including chelation of ferrous iron, reducing power, scavenging 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals, inhibition of liposome peroxidation and trolox equivalent antioxidant capacity (TEAC). A total of 320 Ross 308 broilers were randomly allocated into four groups: control, basal diet supplemented with 0.5%, 1%, 2% PE. Each group was fed for 35 d. The results showed that the group fed with 0.5% PE had significantly better weight gain, and improved feed conversion ratio (FCR) compared to the control group. Moreover, each PE group significantly reduced coliform and Clostridium perfringens in the ileum and caecum. Additionally, PE group with 0.5% concentration had significantly higher villus height in the jejunum compared to the other group. Furthermore, compared to the control group, each PE group had significantly lower levels of malondialdehyde (MDA) and higher levels of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activity in the serum. In the peripheral blood mononuclear cells (PBMCs) of chickens, each PE group showed significantly higher mRNA levels of antioxidant-regulated genes, including Nrf2, GST, GCLC, SOD1 and HO-1. In contrast, the expression levels of NOX1 and ROMO1 genes were significantly lower. In conclusion, the inclusion of 0.5% PE in the basal diet could have a positive impact on the growth performance of broilers by modulating intestinal characteristics and oxidative status. Phyllanthus emblica affects the growth performance, oxidative status and intestinal characteristics in broilers. The 0.5% PE group had significantly better weight gain and improved FCR. The 0.5% PE in the basal diet could potentially enhance growth performance by modulating intestinal characteristics and oxidative status in broilers. [ABSTRACT FROM AUTHOR]

Bananas are one of the most popular fruits worldwide, producing over 100 million tons in 2013. Banana peel, a byproduct that represents 40% of the entire banana's weight, is rich in bioactive compounds and has a high antioxidant capacity. Therefore, the aim of this study is to use banana peel powder (BPP) as an antioxidant broiler feed additive. The bioactive compound and antioxidant capacity of BPP were determined. The results showed that BPP contained 872.7 GAE/100 g DM of total phenolic content, and gallocatechin was detected at a concentration of 91 mg/100 g DM, and BPP's ferrous chelating ability, ferric ion reducing ability power, Trolox equivalent antioxidant capacity, and 1,1-diphenyl-2-picrylhydrazyl scavenging capacity indicated its high antioxidant capacity. A total of 216 one-day-old Ross 308 female broiler chicks were randomly assigned to one of four groups that received the basal diet supplemented with 0% (control), 0.5%, 1%, or 2% dry BPP for 35 d. The results showed that the 0.5% BPP-supplemented group had increased serum SOD activity and lowered serum malondialdehyde levels, while the liver mRNA expression of Nrf2, SOD, CAT, GPx, and HO-1 were upregulated in the 0.5% and 1% BPP-supplemented groups. In conclusion, the current study shows that BPP has a potent antioxidant capacity and dietary supplementation with 0.5% BPP enhances antioxidative status, suggesting that BPP has potential as an antioxidant feed additive. Banana peel has abundant bioactive compounds and antioxidant capacity. Banana peel enhance the antioxidant status of broilers by up-regulating Nrf2/ARE associated genes. Banana peel has potential as an antioxidant feed additive in broiler chickens. [ABSTRACT FROM AUTHOR]

This study evaluated the effects of 10% solid-state fermentation (SSF) wheat bran (WB) by Bacillus amyloliquefaciens (BA) and Saccharomyces cerevisiae (SC) in broiler diets, on growth performance, intestinal morphology, and intestinal microbiota and serum characteristics of broiler chickens. The results showed that fermented wheat bran with BA or BA and SC reduced NDF and ADF contents in WB material. A total of 240 male broilers (Ross 308) were randomly allocated into four feeding groups: (1). Basal diet with 10% WB (control treatment). (2). Basal diet that replaced WB with fermented WB by BA (FWBA). (3). Fermented WB by SC (FWSC), and (4). Fermented WB by BA and SC (FWBA+SC), each group was fed these particular diets for 35 d. Results demonstrated that replacement of WB with FWBA and FWBA+SC improved feed conversion ratio (d 1 to d 35) compared to the control group. Moreover, the 10% FWBA group significantly enhanced the lactic acid bacteria count in the ileum of 35 d old broilers. Compared to the control group, the 10% FWBA and 10% FWSC groups, showed significantly increased ileal lactic acid levels, and in the 10% FWSC group, the ileum villus height was significantly increased in 35 d old broilers. However, treatments with 10% FWBA and 10% FWBA+SC had a tendency to reduce serum cholesterol. In conclusion, a 10% FWBA replacement in the diet could ameliorate health status in broilers by improving growth performance, modulating intestinal microbiota and increasing lactic acid in the ileum.

This experiment investigated the effects of wheat bran fermented withTrichoderma pseudokoningii(FWB) on growth performance, intestinal morphology and the incidence of non-specific pathological lesions in broilers.In vitroexperimental results showed that cellulase and xylananse activity of fermented wheat bran reached its peak at day 4 and solid-state fermentation (SSF) enhanced the reducing sugar content. In addition, the possibility ofTrichodermaadhering to the broiler’s crop epitheliums was also discovered. A total of 180 day-oldRoss308 male broilers were randomly distributed into one of the three dietary groups until 35 d of age: basal diet (control), 10% of basal diet replaced with wheat bran (10% WB) or 10% of diet replaced with fermented wheat bran (10% FWB). Results showed that 10% FWB group had lower feed consumption than the others, but improved feed conversion ratio (FCR) for starter phase (1 to 21 d) when compared to the control group. Furthermore, 10% FWB group had significantly increased villus height and villus height/crypt depth ratio in the ileum compared to the control group.Coliformbacteria count in the ileum was lower in the 10% WB group than the control, however, there were no differences between the 10% WB and 10% FWB treatment groups in theC. perfringenscount. There were no morphological changes or incidences of non-specific pathological lesions in the 10% FWB group. These results suggested that replacing 10% of a basal diet with fermented wheat bran could not only improve growth performance but also provide optimal intestinal morphology in broilers.
