The purpose of this research was to determine the effect of increasing the provision shrub on milk solid non fat content of Friesian Holstein dairy cattle. Research material used was 9 Friesian Holstein dairy cattle on the second lactation at the sixth month lactation with body weight (BW) of 436 ± 48.67 kg, milk production of 8.86 ± 1.2 liter. Single factor experiment arranged in Complete Random Design with 3 treatments, each replicated for three times, was used in this experiment. The cows were fed with concentrate feed (Crude Protein = 13.42%) added by shrub flour at three levels of 0 % BW (t0), 0.03 % BW (t1), 0.05 % BW (t2), and maize straw as forage at each level of shrub flour in the concentrate. The ratio between concentrate and forage 60%:40%. Obtained data was calculated by ANOVA. Results showed that the average consumption of dry matter feed determined at t0, t1, and t2 were 10.22; 10.70 and 11.63 kg/cow/day (P>0.05), respectively. The average of milk solid non fat of t0, t1 and t2 were 0.672; 0.811 and 0.864 kg/liter (P>0.05), respectively. However shrub flour providing in the concentrate until level of 0.05% BW did not increase milk solid non fat of Friesian Holstein dairy cattle milk solid non fat.
