Studies on liver sufficiency of cows fed on food with unbalanced mineral composition.
In 90 cows of black white and red white race, aged 3-9 years and of 450 kg mean body weight fed on food with low level of Ca, P, and Na, several parameters of protein, carbohydrates and lipid liver metabolism before and after supply of special mineral mixtures were evaluated. After the supply the increased concentration of total protein, urea and cholesterol esters and decrease of AspAT, AlAT, and AP activities were recorded in the blood. Cholesterol esters: total cholesterol ratio improved and a slight increase of milk yield and content of fat in milk was observed. Food mineral mixtures favourably influenced the stabilization of liver metabolism.
