“…These results suggested that the antioxidant capacity of broiler chickens was improved by YC-EHY supplementation. Consistently, supplementing yeast-derived products including yeast culture improved serum and hepatic SOD, GPX, and CAT activities but decreased MDA concentration in animals ( Bu et al., 2019 ; Timothée Andriamialinirina et al., 2020 ; He et al., 2021 ). Up to date, the effect of YC-EHY on antioxidant capacity has not been found in any animals.…”

Yeast culture plus enzymatically hydrolyzed yeast cell wall ( YC-EHY ) contains crude protein, mannan-oligosaccharide, β-glucan and yeast culture. This study was carried out to explore the effects of dietary YC-EHY at different levels on growth performance, antioxidant capacity, and immune function of broiler chickens. A total of 320 one-day-age male broiler chicks were allocated into 4 groups and were fed with a basal diet supplemented with 0 mg/kg (the control group), 50 mg/kg, 100 mg/kg, 150 mg/kg YC-EHY for 42 d. Dietary YC-EHY improved average daily gain and feed efficiency during the starter, grower, and overall periods as well as average body weight of broiler chickens on 42 d (linear and quadratic, P < 0.05). Broiler chickens fed with YC-EHY quadratically increased jejunal sucrase activity on 21 d (quadratic, P < 0.05), and linearly and quadratically enhanced maltase activity on 21 and 42 d (linear and quadratic, P < 0.05). Supplementing YC-EHY linearly and quadratically enhanced jejunal superoxide dismutase ( SOD ) activity on 21 and 42 d and glutathione peroxidase ( GPX ) activity on 42 d whereas decreased malonaldehyde ( MDA ) concentration on 42 d (linear and quadratic, P < 0.05). Consistently, the jejunal genes expression of nuclear factor erythroid 2-related factor 2 ( Nrf2 ) and SOD1 on 21 and 42 d, heme oxygenase-1 ( HO-1 ) and GPX1 on 42 d were enhanced by YC-EHY supplementation (linear and quadratic, P < 0.05). The concentrations of jejunal immunoglobulin G ( IgG ) on 21 and 42 d and secreted immunoglobulin A ( SIgA ) on 42 d were linearly and quadratically elevated by supplementing YC-EHY (linear and quadratic, P < 0.05). Dietary YC-EHY quadratically increased jejunal IgG and IgM genes expression on 21 d (quadratic, P < 0.05), and linearly and quadratically enhanced the genes expression of IgG and IgM on 42 d (linear and quadratic, P < 0.05). Overall, this study indicated that supplementing YC-EHY could exert beneficial effects on growth performance, intestinal antioxidant capacity and immune function in broiler chickens.

“…In addition, Gheisari and Kholeghipour [ 9 ] found that broiler chickens fed SC at a concentration of 0.02% had higher antibody titers against NDV than the control at 38 d of age, but it did not affect AI titers. The positive effect of SC on immune response could be attributed to its cell wall constituents, including chitin, mannan and glucan, which have immunostimulant effects [ 2 , 71 , 75 , 76 , 77 , 78 ].…”

Probiotics, such as active yeasts, are widely used to enhance poultry production and reduce feeding costs. This study aimed to investigate the antioxidant and immune responses of broilers to different concentrations of active Saccharomyces cerevisiae (SC) when supplemented to two types of diets. A total of 216 1-day-old Arbor Acres unsexed chicks were used in a factorial design, involving two feeds (regular- versus low-density diet) and three concentrations of SC (0%, 0.02% and 0.04%). The results revealed that the low-density diet reduced the body weight and production index of broilers. The addition of SC improved the production index more than the control diet. Total antioxidant capacity (TAC), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and eosinophils were significantly higher in response to the regular-density diet than the low-density diet; however, phagocytic activity (PA), lymphocyte and lysozyme activity (LYS) were lower. Saccharomyces cerevisiae reduced ALT, AST, malondialdehyde (MAD) and TAC more than the standard set, but improved packed cell volume (PCV), hemoglobin (Hgb), red blood cells (RBCs), lymphocytes, monocytes, heterophils, phagocytic index (PI) and the immune response to Newcastle disease virus (NDV) and avian influenza (AI). In conclusion, supplementation of a regular- or low-density diet with SC at a concentration of 0.02% or 0.04% improved the antioxidant parameters, immune status and production index of broilers against stress and infectious agents.

“…A number of researches in poultry have been conducted to evaluate the function of LY, which indicated that LY is an effective feed additive which can improve growth performance and health of broilers 15,16 . Although He et al 28 . reported that dietary LY supplementation had no significant effects on ADG and FCR during the whole experimental period, Sousa et al 29 .…”

BACKGROUND This experiment was to investigate the effect of dietary live yeast (LY, 1 × 1010 CFU g−1) supplementation on serum metabolic parameters, meat quality as well as antioxidant enzyme activity of transported broilers. A total of 192 one‐day‐old broilers were randomly assigned to four treatments with six replicates and eight chicks per replicate: a basal diet without transportation (CON), a basal diet containing 0 (T), 500 (T + LY500) and 1000 mg kg−1 (T + LY1000) LY with 3 h of transportation after feeding for 42 days, respectively. The serum and muscle samples of broilers were collected immediately after 3 h of transportation. RESULTS A higher (P < 0.05) final body weight and average daily weight gain were observed in T + LY1000 group compared with CON and T groups. The T + LY1000 group reduced (P < 0.05) the serum lactate contents and improved (P < 0.05) the pH24h and decreased (P < 0.05) the drip loss in muscles of transported‐broilers. Also, the T + LY1000 group enhanced (P < 0.05) the total‐antioxidant capacity and reduced (P < 0.05) the malondialdehyde in serum and muscles. Besides, the messenger RNA (mRNA) expression of avian uncoupling protein (avUCP) in muscles was down‐regulated (P < 0.05) of T + LY1000 group compared with T group. CONCLUSION Dietary LY supplementation alleviates transport‐stress‐impaired meat quality of broilers through maintaining muscle energy metabolism and antioxidant status. Therefore, LY may serve as a potential protector for broilers under transport stress in the future. © 2022 The Authors.
