TMR: total mixed ration; pTMR: partial mixed ration; ^# Grazing period (3 weeks): P1—May, P2—June, P3—June/July; SEM: standard error of the mean; AI: Atherogenicity Index; TI: Thrombogenicity Index; h/H (hypocholesterolemic/Hypercholesterolemic ratio); HPI: Health Promoting Index. ^a,b Mean values within a row without a common superscript differ significantly (p < 0.05). Statistically significant difference: * p < 0.05; ** p < 0.01; *** p < 0.001.
