Moreover, tritordeum meadow (i) had a protective effect on liver function (decreased enzyme activity), which contributes to disease prevention; (ii) the increased plasma albumin concentration indicates that these ewes were not exposed to any stresses that could impact their welfare; (iii) nutritional and immune statuses and the increased IgA concentration contributed to the prevention of infections and improved their productive performance and antioxidant capacity. The gene discussed is CD79A; the disease is infection.
