“…These results align with previous research, which demonstrated a similar enhancement in the average daily gain and feed conversion rate of Holstein bulls when YPS was added to their feed (Ma et al, 2015). Nonetheless, it's important to note that studies involving poultry have shown varying effects of YPS on weight gain and feed conversion rate, possibly attributable to differences in factors such as YPS dosage, chicken breeds, and YPS composition (Ahiwe et al, 2019). Furthermore, while our study observed an increase in milk production in female donkeys with YPS supplementation, it is worth mentioning that no prior research has reported similar effects on animal milk production.…”

IntroductionThe Dezhou donkey, a prominent Chinese breed, is known for its remarkable size, rapid growth, and resilience to tough feeding conditions, and disease resistance. These traits are crucial in meeting the growing demand for Ejiao and donkey meat. Yeast polysaccharide (YPS), a functional polysaccharide complex known for its immune-enhancing and growth-promoting properties in livestock and poultry, remains relatively understudied in donkeys.ObjectivesThis study aimed to investigate the impact of YPS supplementation on lactating and growing Dezhou donkey jennies and foals.Materials and methodsTwelve 45-day-old Dezhou donkey foals and their jennies, matched for body weight and age, were randomly allocated to two dietary groups: a control group receiving a basal diet and an experimental group receiving the basal diet supplemented with 10 g/pen of YPS. The experiment was conducted over a 23-day period, during which donkey foals and lactating jennies were co-housed.Results and discussionThe findings revealed that YPS supplementation had no adverse effects on milk production or composition in Dezhou donkey jennies but significantly increased feed intake. Additionally, YPS was associated with increased plasma glucose and creatinine concentrations in foals, while tending to decrease alkaline phosphatase, white blood cell count, red blood cell count, and hemoglobin levels (p < 0.10). Immune indices demonstrated that YPS supplementation elevated the levels of immunoglobulin A (IgA) and immunoglobulin G (IgG) in jennies (p < 0.05) and increased complement component C4 concentrations in foals (p < 0.05). Moreover, YPS positively influenced the fecal microbiome, promoting the abundance of beneficial microorganisms such as Lactobacillus and Prevotella in donkey foals and Terriporobacter and Cellulosilyticum in jennies, all of which contribute to enhanced feed digestion. Additionally, YPS induced alterations in the plasma metabolome for both jennies and foals, with a predominant presence of lipids and lipid-like molecules. Notably, YPS increased the concentrations of specific lipid metabolites, including 13,14-Dihydro PGF2a, 2-Isopropylmalic acid, 2,3-Dinor-TXB2, Triterpenoids, Taurocholic acid, and 3b-Allotetrahydrocortisol, all of which are associated with improved animal growth.ConclusionIn conclusion, this study suggests that dietary supplementation of YPS enhances feed intake, boosts immunity by increasing immunoglobulin levels, stimulates the growth-promoting gut microbiota (Lactobacillus and Prevotella), and exerts no adverse effects on the metabolism of both Dezhou donkey jennies and foals.

“…However, a significant difference in growth performance was not observed between chickens fed YG supplemented diet and control diet. Similarly, Ahiwe et al (2019) noted that yeast glycan and yeast mannan supplements did not affect body weight gain and feed conversion ratio in the starter phase in broiler chickens. Unlike the current study, Wang et al (2021) reported that dietary yeast-derived products could improve average daily gain and feed efficiency in broiler chickens.…”

“…The eight treatments consisted of a positive control ( PC ) [without supplementation and not challenged]; negative control ( NC ) [without supplementation but challenged with salmonella LPS] at days 13, 15, and 17; whole yeast (added at 2.0 g/kg diet) and also challenged with LPS ( WYC ); yeast cell wall (added at 2.0 g/kg diet) and challenged ( YCWC ); yeast glucan (added at 0.20 g/kg diet) and also challenged with LPS ( YGC ); yeast mannan (added at 0.20 g/kg diet) and also challenged with LPS ( YMC ); zinc bacitracin (added at 50 ppm) and also challenged with LPS ( ZNBC ); and Salinomycin (added at 60 ppm) and also challenged with LPS ( SALC ). The additives were included according to manufacturer's recommendation, and have been previously used at the same levels for healthy chickens with excellent results (Ahiwe et al., 2018; Ahiwe et al., 2019). Feed and water were offered ad libitum .…”

The objective of this study was to assess the effect of dietary yeast products on broiler chickens challenged with salmonella lipopolysaccharide (LPS). The chicks were divided into 8 treatments with 6 replicates and 9 birds per replicate. The treatments consisted of a positive control (PC) [without supplementation and not challenged]; negative control (NC) [without supplementation but challenged]; whole yeast and challenged; yeast cell wall and challenged; yeast glucan and challenged; yeast mannan and challenged; zinc bacitracin and challenged; and Salinomycin and challenged. Whole yeast or Yeast cell wall was included at 2.0 g/kg diet. Yeast glucan or mannan was added at 0.20 g/kg diet. Zinc bacitracin (ZNB) and Salinomycin (SAL) was included at 50 and 60 ppm, respectively. Dietary treatments had no effect (P > 0.05) on feed intake (FI) at day 10. Supplementation with yeast and its derivatives improved (P < 0.05) body weight gain (BWG) and feed conversion ratio (FCR) on day 10. On days 24 and 35, LPS challenge declined FI, BWG, FCR, and flock uniformity (day 28) in the NC group compared to the PC group. Yeast products and antibiotics improved (P < 0.05) FI, BWG, FCR, and flock uniformity in LPS-challenged birds. On day 24, spleen weight increased while bursa weight decreased in the NC group relative to the PC group; this effect was reversed (P < 0.05) by feeding all yeasts and antibiotics. On day 24, application of all the dietary treatments ameliorated the changes observed in white blood cell, lymphocyte and monocyte counts as well as albumin and immunoglobulin G of NC birds. On day 35, all yeasts additives, ZNB and SAL improved (P < 0.05) the meat yield of broilers challenged with LPS. In conclusion, supplementation of diets with yeast and its derivatives can ameliorate the negative effects of salmonella LPS challenge on broiler chicks, thus improving the performance, flock uniformity, and meat yield.
