The aim of this study was to produce the low protein feed that dairy cow become healthy. Dairy cows were divided into two feeds given the low protein feeds (CP16%, CPd/CP64.7%, CPd10.7), and high protein feeds (CP16%, CPd/CP64.7%, CPd10.7). As a result, dairy cows given to the low protein feeds was tended to improve the result of dry matter intake, quantity of sechation milk and breeding characteristics and were lower than the high protein feed, at MUN, the first gastric juice ammonia nitrogen and BUN (p0.05). On the basis of the result, low protein feed was become healthy feed for dairy cows which do not suffer from metabolism disorder and breeding disorder.
