摘要: Summary Sixteen high-producing Holstein cows were used in a 112-day continuous feeding trial to study the effect of highly fortified vitamin-mineral supplement with 15:85 and 60:40 hay-concentrate ratios on milk yield composition, conversion total digestible nutrients (TDN) fat-corrected (FCM), digestibility rations. The fed supplemented low-concentrate ration maintained their level FCM production significantly (P
