This experiment was conducted to determine the effect of different sources of pectin feedstuffs on blood metabolites in early lactating Holstein cows. Eight primiparous early lactating Holstein cows (60 ± 23 d postpartum, weighing 530 ± 60 kg) were assigned into a duplicated 4 × 4 Latin square design 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. Blood samples were collected from the jugular vein 2h after the morning feeding. Blood serum was collected after centrifuged at 1,500 × g for 20 min, frozen at – 40°C, and later analyzed for glucose, urea N, cholesterol, triglyceride, alkaline phosphate and albumin. Blood metabolites data and DMI are shown in Table 1.There were no differences (P > 0.05) on daily intake of DM (kg/d) (Table 1). Similarly, no treatments effects were observed blood metabolites (Table 1). These data suggest that, the addition of sources of pectin feedstuffs 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 DMI and blood metabolites.
