“…A measure of redox status is the balance between oxidative factors such as lipid peroxidation products (malondialdehyde or peroxide radicals) and endogenous and exogenous antioxidant substances [3]. In the present study, the use of Yarrowia lipolytica or Saccharomyces cerevisiae yeast resulted in a significant increase in catalase (CAT) and superoxide dismutase (SOD) activity, which may indicate their role in the activation of antioxidant enzymes and reduction of peroxidation products [9]. According to Aluwong et al [3], an increase in antioxidant enzyme activity may be associated with increased resistance to colonization and susceptibility to environmental pathogens, which can be achieved by including fodder yeast in poultry diets.…”

“…The chemical composition and physical properties of Yarrowia lipolytica make it an interesting feed additive. Studies have already been conducted on the use of Yarrowia lipolytica as a factor affecting the gut microbiota and fattening efficiency [8][9][10], and the results have been promising. However, it has not been clarified whether Yarrowia lipolytica yeast, like Saccharomyces cerevisiae, can improve the availability of minerals as well as metabolic processes associated with redox reactions.…”

“…Many studies indicate that the effect of fodder yeast can be enhanced by using it in combination with probiotics [9,11]. As the addition of a probiotic bacteria to feed containing Saccharomyces cerevisiae cell wall has been shown to stimulate body weight and mineral availability in broilers [12] we decided to test it together with the addition with YL.…”

The probiotic-prebiotic properties and chemical composition of Yarrowia lipolytica yeast (YL), predisposes it for use as a turkey feed additive. The aim of the study was to determine whether YL in the diet of turkeys would exert more beneficial effect by stimulating antioxidant reactions and increasing mineral availability than Saccharomyces cerevisiae (SC). An additional aim of the study was to test whether the addition of a probiotic bacteria to feed containing Yarrowia lipolytica or Saccharomyces cerevisiae yeast would enhance their effect. The study was conducted on turkeys from seven to 112 days of age to determine the effects of a 3% addition of YL to the diet, as an alternative to the standard SC. It was analysed whether the use of a probiotic (Bacillus licheniformis, Bacillus subtilis) together with yeast would be more effective. Both the yeast (YL or SC) and the probiotic stimulated antioxidant mechanisms (increased CAT; reduced MDA), but the addition of SC was less effective. The inclusion of YL in the feed increased the plasma content of Ca, Mg, Cu, Zn and Fe in the blood turkeys and lowered the content of cholesterol and triacylglycerols. The combined use of yeast (YL or SC) with a probiotic enhances the antioxidant effect while inhibiting of lipid peroxidation. The combined use of yeast with a probiotic can be recommended in cases of stimulation of oxidative reactions (e.g., stress or infection)

“…One month later lysozyme concentrations in the same group were also significantly higher compared to the beginning (P<0.001). Czech et al (2014) also observed that the addition of Yarrowia lipolytica yeast in a dose of 6% increase plasma lysozyme in turkey hens. Tawab et al (2015) revealed that broilers fed on prebiotic increase the lysozyme concentrations more than broilers fed on probiotic.…”

SummaryThe experiments for evaluation of the effect of Immunobeta were performed with turkeys and organically reared layer hens. Turkeys received Immunobeta at a dose of 4 g/kg feed during the beginning of lay (cold period), thermoneutral period and hot summer period. In hens, two dietary levels of Immunobeta were tested: 2 g/kg and 4 g/kg. Blood serum and egg lysozyme levels, alternative pathway of complement activation (APCA) and beta-lysins concentrations were determined. It was found out that Immunobeta had a beneficial effect on serum lysozyme, APCA activity and beta-lysins in turkeys and hens. The lysozyme concentration in egg white was statistically significantly higher in eggs produced by birds treated with both doses of the immunomodulator.
