|Vitamin A concentration in different samples from clinically affected calves compared to reference values|
|Samples||Concentrations||Normal value (16)|
|Feeda||1360 IU/kg||400000 IU/kg|
|Milkb||36.1 IU/L||698 IU/L|
|Serum Ac||1055 IU/L||43605 IU/L|
|Serum Bd||130 IU/L||43605 IU/L|
a Five feed samples were chose randomly and vitamin A concentration was shown in average (p < 0.01).
b Three milk samples from the affected cows were chose randomly and vitamin A concentration was shown in average(p < 0.05).
c Serum A was prepared from the affected calves at the early stage of disease.
d Serum B was prepared from the affected calves at the late stage.
