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 (pā€‰<ā€‰0.01).

b Three milk samples from the affected cows were chose randomly and vitamin A concentration was shown in average(pā€‰<ā€‰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.
