The problem of the milk cow nourishment management in the dairy farming spot tends to have too much protein by the high protein feed with lack of calorie by the lack of dried foods intake after the childbirth. In addition, from the remarkable rise of the recent assorted feed price, the low cost of the feed is a big problem. Therefore I decided to aim at the development of the low cost low protein feed salary technology that a milk cow had few burdens in this study and I established a high protein standard ward (CP 16%, CPd/CP ratio 64.7%, NFC/CPd 3.6) and the low protein standard ward (CP 14%, CPd/CP ratio 62.0%, NFC/CPd 4.4) that I stayed and used of food such as bean-curd refuse or the fermentation brewer's grains that I did and weighed the secretion of milk characteristics against the corn subject at this time. As a result, I show a tendency to improve dried foods intake, quantity of secretion of milk and milk protein production efficiency, and MUN, the first gastric juice ammonia nitrogen, blood BUN lower and can expect the low protein feed which used the remainder of food such as bean-curd refuse or the fermentation brewer's grains as the breeding management that is hard to have a metabolism obstacle by the protein surplus and a breeding obstacle.
