Research Abstract

The metabolism of arginine and its relating compounds by mammary tissues were investigated to clear the nutritional role of arginine in dairy cows. After calving, extraction rate of plasma ariginine by mammary tissues dramatically increased. Supplementation of low degradable dietary protein increased the conversion ratio of the extracted arginine to milk protein without the elevation of arterial arginine. The extent of splanchnic extraction of absorbed arginine may restrict the arginine supply to the mammary tissues.
