Diet supplementation had a beneficial influence on the health status of ewes, leading to increased nonspecific humoral and cellular immune responses in ewes, including gamma globulin concentrations, lysozyme and ceruloplasmin activity levels, respiratory burst activity and potential killing activity of phagocytes, and the proliferative response of mitogen-stimulated T cells and B cells.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:The objective of this study was to determine the effect of supplementing diets fed to ewes (in late pregnancy and during lactation or only during lactation) with Saccharomyces cerevisiae dried brewer’s yeast on the yield and chemical composition of milk and on selected parameters of humoral and cellular immunity.
📊
Key Findings & Data:The investigated indicators were analyzed on days 28 and 70 of lactation.
💡
Conclusion & Impact:Diet supplementation had a beneficial influence on the health status of ewes, leading to increased nonspecific humoral and cellular immune responses in ewes, including gamma globulin concentrations, lysozyme and ceruloplasmin activity levels, respiratory burst activity and potential killing activity of phagocytes, and the proliferative response of mitogen-stimulated T cells and B cells.

Abstract

The objective of this study was to determine the effect of supplementing diets fed to ewes (in late pregnancy and during lactation or only during lactation) with Saccharomyces cerevisiae dried brewer’s yeast on the yield and chemical composition of milk and on selected parameters of humoral and cellular immunity. The investigated indicators were analyzed on days 28 and 70 of lactation. The addition of dried yeast contributed to a significant increase in milk yield, and the obtained milk was characterized by a lower somatic cell count, suggesting improved mammary gland health. Diet supplementation had a beneficial influence on the health status of ewes, leading to increased nonspecific humoral and cellular immune responses in ewes, including gamma globulin concentrations, lysozyme and ceruloplasmin activity levels, respiratory burst activity and potential killing activity of phagocytes, and the proliferative response of mitogen-stimulated T cells and B cells.
