Abstract
The current study was performed to explore the effects of dietary supplementation of Saccharomyces cerevisiae hydrolysate (SCH) on growth performance, immune function, and intestinal health in broiler chicken. A total of 300 Ross 308 male broilers (1-day-old) were randomly assigned to 2 dietary treatments including a basal diet (control group), and a basal diet supplemented with SCH feed additive (500 mg/kg in starter and grower phase, and 250 mg/kg in finisher phase). Each treatment had 6 replicates with 25 birds each. The results showed that the addition of SCH promoted growth during d 15 to 28 (P < 0.05). Although the addition of SCH had no significant effect on the intestinal relative indexes, it significantly increased the jejunum villus height (VH) and the ratio of villus height to crypt depth (VCR) of jejunum, and decreased the crypt depth (CD) of ileum (P < 0.05). Furthermore, SCH addition significantly downregulated the mRNA expression of immunomodulatory genes (TNF-α, IL-1β, and IL-6), and upregulated the tight junction genes (ZO-1 and Claudin-1) (P < 0.05). High throughput sequencing analysis of bacterial 16S rRNA revealed that dietary SCH supplementation altered cecum microbiota. Alpha diversity analysis showed that a higher bacterial richness in cecum of broilers fed with SCH. The composition of cecum microbiota regulated by SCH addition was characterized by an increased abundance of Firmicutes and a reduced abundance of Bacteroidetes. At the genus level, dietary SCH resulted in a decrease of Bacteroides and an increase of short-chain fatty acids (SCFA) -producing bacteria including Lactobacillus and Faecalibacterium. Taken together, dietary SCH supplementation can stimulate the growth of broilers by regulating the intestinal immunity and barrier function, and improving the intestinal morphology, which may be related to the enhancement of bacterial diversity and the changes of intestinal microbial composition.

Abstract
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.
