Relationship between Serum Total Cholesterol and Morbidity in Lactating Holstein Cows

Abstract

Serum total cholesterol (T-CHO) were determined in a total of 715 lactating Holstein cows during a period from January to April, 1983. Parity, days after calving and milk yield influenced TCHO level significantly. TDN and CP levels in the ration, as well as body weight, were not significant factors. Morbidity was a factor for changes in T-CHO level. This level decreased significantly in cows with diseases. There was no marked difference in T-CHO level between cows with diseases and healthy ones.
