ABSTRACT An experiment was carried out at National Cattle Research Program (NCRP), Rampur, Chitwan from November to December, 2016 for 30 days to evaluate the effect of bypass protein supplementation on milk production performance of dairy cattle. A total of eight lactating cattle of similar parity, calving date and milk production were selected for experiment. These animals were divided into two groups (control and treatment) by using completely Randomized Design (CRD). Concentrate mixture was prepared by using feed ingredients of Kisan Feed Industries, Patan Industrial State of Lalitpur. Control group were provided 6 kg concentrate mixture whereas treatment group were provided 6 kg concentrate and 1.5 kg formalin treated soybean cake. Experimental animals were allowed to graze for three hours in the pasture lands of NCRP and adlib amount of green grass such as Teosenti, Bajra, Perennial sorghum and local grass was also provided as per availability once a day. Feed intake and milk yield of individual animal was recorded daily. Results revealed that treatment group produced significantly higher (p
