Eight primiparous early lactating Holstein cows (60 ± 23 d postpartum, weighing 530 ± 60 kg) were assigned into a duplicated 4 × 4 Latin square design for evaluated of different pectin rich by products on feed intake, milk production and composition and ruminal pH of lactating dairy cows with 4 3-wk periods. Cows were allocated into 4 diets whit 1)10% barley grain, 2)10% sugar beet pulp, 3)10% wheat bran and 4) 10% dried citrus pulp . Each experimental period was 21 d including 14 d adaptation period and 7 d collecting samples. Milk yield recorded daily and milk samples were taken from each milking times during the last 3 d of each period. Milk samples were subjected to analysis for CP, lactose, fat and SNF. The dry matter intake (DMI), NDFI, milk yield and composition and ruminal pH are presented in the Table 1. There were no differences (P > 0.05) in the daily intake of DM (kg/d), and milk yield and composition, among treatments (Table 1). Similarly, there were no significant differences in ruminal pH among treatment diets (P > 0/05). The NDF intake was significantly different among treatments (P < 0.05). These data suggest that, the addition of sources of pectin feed stuffs at 10% levels (dry matter basis) of the dairy cow ration instead of cereal grain; will decrease the cost of milk production without any negative effect on dairy cows performance.
