The intake of the dry matter (DM), the crude protein (CP) and the metabolizable energy intake (ME) in megacalories per day (Mcal/day) were not affected by the diets. In contrast, the intake of neutral detergent fiber (NDF), in g/kg BW, increased linearly. An increasing linear effect was also observed for the ether extract (EE) intake, whereas a decreasing linear performance was observed for the non-fibrous carbohydrate (NFC) intake. The digestibility of DM, organic matter and NFC decreased linearly with the sunflower cake inclusion, whereas the digestibility of CP, NDF, and EE were not influenced by the diets. No effect was observed for the concentration of serum glucose or urea nitrogen serum. No effect was observed on the urea nitrogen serum in the hours after feeding; however, including sunflower cake in the diets resulted in a quadratic performance for the serum glucose concentrations in the hours after feeding. The average daily gain (ADG) had a decreasing linear effect, and the food conversions of the DM, CP, NDF, NFC and ME had increasing linear effects. The feeding costs decreased with the level of sunflower cake.
