Relationship between postpartal fatty liver and thyroid gland activity during the peripartal and mid dry periods was studied.
Twenty one dry cows were chosen.
Blood samples were obtained on days −30, −2, and +12 related to calving and analized for thyroxine (T4) and triiodothyronine (T3).
A T3/T4 ratio was calculated.
Liver tissue samples were taken 12 d after calving and tested for the lipid content.
Cows were divided into three groups: mild (<20% fat), moderate (20 to 30%), or severe fatty liver (>30%).
Cows, that were affected with severe fatty liver, were hypothyroid prior to development of the condition due to lower T4 concentrations, and had significantly lower concentration of T3 and higher T3/T4 ratios than cows with mild and moderate fatty liver.
Thus, hypothyroid state during mid-dry period may be an early indicator of postpartal fatty liver and may provoke T3/T4 ratio increase in this group of cows.
