Dear Dr Othieno

I have a dairy cow that is five months in-calf. The cow is being milked but off late, its producing yellowish milk that appears like colostrum. Is this normal at this stage of lactation? What factors determine the quantity and quality of milk from a cow. The cow is a jersey/fresian cross in its first lactation.
