Fig. 1

Milk yield and dry matter intake of cows supplemented with a Saccharomyces cerevisiae fermentation product (NTK) or fed a control diet (CON) subjected to an intramammary inflammation challenge with Streptococcus uberis. Data are separated according to experimental period: treatment feeding (Phase 1; 0–44 d), bacteria inoculation and challenge (Phase 2; 45–53 d), post antibiotic recovery (Phase 3; 54–75 d). For Phase 2, milk yield is represented both as daily values (sum of the three daily milkings, circles with full lines) or as single milking values (e.g., morning, noon, and evening yield for the corresponding day on trial, triangles with dotted lines). Superscripts represent differences among groups within each time point (*, P < 0.05; t, 0.05 < P < 0.10)
