Grape seed is rich in vitamin E, flavonoids, and proanthocyanidins and has the potential to be used as an antibiotic substitute in broilers. We investigated the effects of grape seed proanthocyanidin extract (GSPE) on growth performance, immune responses, cecal microflora, and serum metabolism in early stage broilers. Data indicated that GSPE improved broiler growth performance by strengthening antioxidant capacity, enhancing immune responses, and increasing cecal short chain fatty acids. 16S rRNA sequencing indicated that GSPE changed the predominant cecal microflora and induced the metabolism of amino acids, lipids, and carbohydrates. An UPLC-Q-TOF/MS-based metabolomics analysis identified 23 serum metabolites (mainly related to lipid, amino acid, and alkaloid) were extremely changed by GSPE treatment. The correlations between the changes of cecal microflora and serum metabolites in birds fed with GSPE were analyzed. Hence, GSPE potentially provides active ingredients that may be used as antibiotic substitute and reduces environmental pollution by grape by-products.

Abstract The study was conducted to investigate effects of yeast cell wall product on growth performance, immune responses, and gene expression of tight junction proteins of weaned pigs. A total of 112 weaned pigs (7.98 ± 0.43 kg BW) were randomly assigned to 2 dietary treatments (8 pigs/pen; 7 replicates/treatments) for 4 weeks in a randomized complete block design (block = BW). Dietary treatments were 1) a commercial basal nursery diet (CON) and 2) CON + 0.05% yeast cell wall product (YCW, EasyBio Inc., Seoul, Korea). Blood was collected from one randomly selected pig per pen on d 0, 7, and 14 after weaning. The randomly selected one pig per replicate was euthanized to collect ileum tissue samples at the end of the experimental period. Measurements were growth performance, number of white blood cells (WBC) by an automated hematology analyzer calibrated for porcine blood, cortisol, tumor necrosis factor-α (TNF-α), transforming growth factor-β1, interleukin-1β (IL-1β), and interleukin-6 (IL-6) by the ELISA, and gene expression of tight junction in ileum tissues. Data were analyzed using the PROC GLM procedure of SAS. The statistical model for every measurement included dietary effect and BW as a covariate. Pigs fed YCW had higher (P < 0.10) ADG than those fed CON during overall experimental period. Pigs fed YCW had lower WBC on d 14 (P < 0.10), TNF-α on d 7 (P < 0.10), and decreased IL-1β on d 14 (P < 0.05) than those fed CON. In addition, The YCW increased (P < 0.05) expression of Claudin family, Occludin, Muc1, INF-α, and IL-6, but decreased (P < 0.05) expression of TNF-α genes in the ileum tissues compared with CON. In conclusion, addition of yeast cell wall product in the nursery diet improved growth performance and gut health and modified immune responses of weaned pigs.

Dietary yeast cell wall products (YCW) are recognized as a feed additive due to multifunctional benefits by the biological response modulators. Thus, this study was conducted to verify a potential advantage of YCW for improving growth performance, nutrient digestibility, immune responses, and intestinal health and microbiota of weaned pigs. A total of 112 weaned pigs (7.99 ± 1.10 kg of body weight; 28 days old) were arbitrarily allocated to two experimental treatments with eight pigs (four barrows and four gilts) per pen and seven replicate pens per treatment in a completely randomized block design (block = BW and sex): (1) a basal diet based on corn and soybean meal (CON) and (2) CON + 0.05% YCW. The experimental period was for 4 weeks. There were no differences in final body weight, average daily feed intake, and gain-to-feed ratio between dietary treatments. In contrast, pigs fed YCW had higher average daily gain (p = 0.088) and apparent ileal digestibility of DM (p < 0.05) and energy (p = 0.052) and lower diarrhea frequency (p = 0.083) than those fed control diet (CON). Pigs fed YCW also had a higher (p < 0.05) ratio between villus height and crypt depth, villus width and area, and goblet cell counts in the duodenum and/or jejunum than those fed CON. Dietary YCW decreased (p < 0.05) serum TNF-α and IL–1β of weaned pigs on day 7 and 14, respectively, compared with CON. Furthermore, pigs fed YCW had higher (p < 0.05) ileal gene expression of claudin family, occludin, MUC1, INF-γ, and IL-6 and lower (p < 0.05) that of TNF-α than those fed CON. Lastly, there were no differences in the relative abundance of bacteria at the phylum level between CON and YCW. However, dietary YCW increased (p < 0.05) the relative abundance of genera Prevotella and Roseburia compared with CON. This study provided that dietary YCW improved growth rate, nutritional digestibility, and intestinal health and modified immune responses and intestinal microbiota of weaned pigs.
