This experiment was conducted to investigate effects of a form of oligosaccharide (glucosamine D) as feed supplements for 2 months on milking cows with respect to the disease resistance. Two different groups were supplemented glucosamine-D of 1.5g (GD30) and 5g (GD100) per day, respectively. On group of GD100, Somatic cell counts and milk urea nitrogen were decreased on cows with group of GD100. However, there were shown no effects on GD30 treatment. Milkability would be favorable on the group of GD100 treatment. This phenomenon would be interpreted of resistance of disease by way of immune serum system.
