CON, Basal diet; 0.3LC, Basal diet - MgO - 0.3% limestone + 0.40% marine-derived Ca-Mg complex; 0.7LC, basal diet - MgO - 0.7% limestone + 0.40% marine-derived Ca-Mg complex.
Different superscripts within a row indicate a significant difference (p < 0.05) in response to treatment diets CON vs. 0.3LC and 0.7LC.
Different superscripts within a row indicate a significant difference (p < 0.05) among parity.
