“…This finding is in agreement with that of Tuoi et al [10], who observed that inclusion of combinations of 1.0 g/kg β-glucan and MOS in the piglet diet markedly increased the abundance of Lactobacillus spp. However, this contrasted with a previous report in which an increase in intestinal microbiota was not observed [34]. These inconsistent results may be due to the different inclusion levels, dietary compositions, or HY purity utilized.…”

Background and Aim: Weaning pigs normally suffer from many stressors which have impaired growth performance and immunity. Hydrolyzed yeast has been proposed as an alternative feed additive. The aim of this study was to investigate the effects of various levels of hydrolyzed yeast (HY) supplementation in the feed of weaning pigs on growth performance, diarrhea incidence, immunity, antioxidant capacity, and microbial populations. Materials and Methods: A total of 144 crossbred weaning pigs (Duroc × Landrace × Large White) with a mean body weight (BW) of 7.46 kg were randomly assigned to one of four treatments during a 5-week feeding trial. Treatments consisted of a basal diet without HY inclusion (control), or the basal diet supplemented with HY at 0.5, 1.0, and 1.5 g/kg of diet, respectively. Results: Piglets fed with 1.0 or 1.5 g/kg HY presented significantly increased BW (p=0.009) and decreased incidence of diarrhea (p=0.001). The final BW (p=0.012), average daily gain (p=0.094), and average daily feed intake (p=0.091) showed a linear improvement with the level of HY inclusion. However, the gain-to-feed ratio was unaffected by dietary treatments. Linear responses to the HY supplementation levels were also observed for blood urea nitrogen (p=0.030), total protein (p=0.017), lymphocyte percentage (p=0.064), catalase activity (p=0.089), malondialdehyde (MDA) level (p=0.001), Salmonella spp. (p=0.024), Escherichia coli (p=0.021), and Lactobacillus spp. (p=0.048). Dietary inclusion of HY at 1.0 and 1.5 g/kg resulted in increased immunoglobulin A and G secretions (p=0.042 and p=0.022, respectively) and decreased MDA concentration (p<0.01) and Salmonella spp. (p=0.026) and E. coli (p=0.050). Conclusion: It was concluded that HY inclusion at 1.0 and 1.5 g/kg in the diet of weaning pigs improve BW, immunoglobulin secretion, and antioxidant enzyme activity, whereas it lowers diarrhea occurrence, lipid peroxidation, and pathogenic bacteria in weaning pigs.

“…Each pen, housing 6 piglets of 3 barrows and 3 gilts, represented an experimental unit. The dietary inclusion at the level of 0.75% for the three prebiotics and the oat b-glucan in the experimental diets were to reflect the ranges of their dietary supplementation levels reported in the current literature (Mair et al, 2010;Park et al, 2018;Xing et al, 2018;Uerlings et al, 2021) in hopefully eliciting positive changes in growth performance, nutrition and and/or physiological endpoints while also being economically feasible for the industry should commercial applications of these potential gut modifiers as feed additives be attempted.…”

“…In agreement with our findings, later work done by Hiss and Sauerwein (2003) who found that supplementing up to 0.03% of yeast-derived b-(1-3/1-6)-glucan had a trend to increase ADFI but did not improve ADG in the weanling pigs. Hahn et al (2006) in supplementing up to 0.04% bglucan and Park et al (2018) in supplementing up to 0.40% bglucan did not report consistent improvements in performances in weanling pigs. In a recent study by Wu et al (2021), dietary supplementation (at 0.02%) of b-glucan of bacterial origin could improve gut morphology, biochemical and microbiome endpoints with improvement in ADG but not ADFI and F:G ratio in weanling pigs.…”

“…Three previous studies with b-glucan supplemented as a gut modifier feed additive primarily focused on gut mucosal morphology, blood biochemical, microbiota and growth performance responses without reporting nutrient digestibility in weanling pigs (Dritz et al, 1995;Hiss and Sauerwein, 2003;Wu et al, 2021). Whereas two other studies with dietary supplementations of gradient levels of b-(1-3/1-6)-glucan (b-G) (0 -0.40%) and yeast b-glucan (0.01 to 0.04%) shown linear responses of improvements in the total tract DM digestibility in the weanling pig (Hahn et al, 2006;Park et al, 2018). Hence, the effects of dietary supplementations of b-glucans as a gut modifier feed additive on nutrient digestibility are not consistent and are likely affected by sources, doses and test conditions of b-glucans used in the reported weanling pig studies.…”

There are growing interests in developing novel gut modifier feed additives and alternative therapeutics to replace antimicrobials to enhance efficiency of nutrient utilization and to address the antimicrobial resistance threat to public health facing the global pork production. Biological mechanisms of supplementing lactose for enhancing weanling pig growth and nitrogen utilization are unclear. Thus, this study was prompted to determine effects of dietary supplementation of 3 prebiotics and oat β-glucan vs. a sub-therapeutic antibiotic on growth performance, whole-body protein utilization status, the apparent total tract dry matter (DM) and lactose digestibility in weanling pigs fed corn and soybean meal (SBM)-based diets. Six experimental diets were formulated with corn (40%), SBM (28%) and supplemented with dried whey powder (20%) and fish meal (9%) with titanium oxide (0.30%) as the digestibility marker. Diet 1 (NC, negative control), as the basal diet, contained no antibiotics and no supplemental prebiotics or β-glucan. Diet 2 (PC, positive control), contained an antibiotic premix (Lincomix-44 at 0.10%) in the basal diet at the expense of cornstarch. Diets 3, 5 and 6 contained 0.75% of the three test prebiotics of retrograded cornstarch (Diet 3), Fibersol-2 (Diet 5, a modified digestion-resistant maltodextrin) and inulin (Diet 6), and the viscous soluble fiber oat β-glucan (Diet 4), respectively, at the expense of cornstarch. A total of 144 Yorkshire pigs, at the age of 21 days (d) and an average body weight (BW) of 5.5 kg, were allocated to 12 floor pens with 3 barrows and 3 gilts per pen, and fed one of the 6 diets for 21 d in 2 study blocks according to a completely randomized block design. Initial and final pig BW, average daily gain (ADG), average daily feed intake (ADFI), representative pig plasma urea concentration as well as the apparent total tract DM and lactose digestibility during d 8-15 were measured. Analyses of variances, Dunnett’s and Tukey’s tests were conducted on the endpoints by using the SAS mixed model. There were no differences (P > 0.05) in ADG, ADFI, feed to gain ratio, plasma urea concentration, the apparent total tract apparent DM and lactose digestibility and the predicted whole-gut lactase digestive capacity among the diets, as examined by the Tukey’s test. There were no differences (P > 0.05) in these endpoints between each of the four treatment diets and the NC or the PC diet as examined by the Dunnett’s test. The total tract lactose digestibility was determined to be at 100%. The predicted whole-gut lactase digestive capacity was about eight times of the daily lactose intake when dietary lactose contents were supplemented at 10 - 12% (as-fed basis). In conclusion, dietary supplementation (at 0.75%) of the prebiotics and the oat β-glucan did not significantly affect the major growth performance endpoints, whole-body protein utilization status as well as the apparent total tract DM and lactose digestibility in the weanling pigs fed the corn and SBM-based diets. The promoting effect for growth and nitrogen utilization associated with dietary supplementation of lactose is due to the fact that lactose is a completely and rapidly digestible sugar rather than acting as an effective prebiotic in weanling pig nutrition.

“…Overall, yeast β-glucans provide a valuable tool to the ruminant producer as an alternative to antibiotics (Dina and Mariët, 2018). β-glucan from rice bran could have alternative antibiotic effects and improve productivity of weaned pigs (Park et al, 2018).…”

| This study was carried out to find the pathological changes on mice infected experimentally with Absidia spp isolated from cats, and immune modulator effects of β-glucan compound against Absidia spp. To achieve the goal, Forty mice were divided randomly into two groups, 1 st group (n=20 mice) fed on diet supplement with 100mg/kg diet of β-glucan for 5weeks. 2 nd group (n=20 mice) was served as a control group. The two groups were challenged with 1×10 7 fungal cells/ml I/P of virulent Absidia spp. The result showed that 5out of 20 mice in the first group died at 1-3 days and 14 out of 20 mice in the second group. The level of protection observed in the mice of the first group showed in 75% of infected immunized mice, where 30% protection was reported in mice of the second group. The histopathological examination in the control group of mice showed acute suppurative inflammation in the examined organs at 24-72 hour post infection with necrosis, inflammatory cells infiltration and the mold and hyphae were observed in the liver, kidney, spleen and lung, as well as moderate to mild pathological lesion at day 45 post-inoculation, Mononuclear cells and neutrophils were seen in most examined organs of the 1st group. The present study was concluded that the Absidia spp. causes high pathological lesions and the β-glucan as immunomodulater alone provided partial protective immunity against lethal doses of Absidia spp. Histopathological Study and Effect of Β-Glucan asImmunomodulater in Mice Infected by Absidia spp. citation | Alkhalidi AA, Aljumaily S, Taher MG, Mohammed ZI (2019).
