Özet

The objectives of this research were to evaluate the effects of increasing levels of dry corn gluten feed (DCGF) on dry matter intake (DMI), chewing activity, and rumen fermentation when used to replace a portion of corn silage in diets for lactating Holstein cows. Eight lactating Holstein primiparous cows averaging 98 +/- 20 d in milk and weighing 515 +/- 20 kg were randomly assigned in a 4x4 Latin square design with 4 week periods. Dietary treatments were 1) a control diets (C) of 50% forage (corn silage and wheat straw, 35%, 15% DM basis, respectively), 2) a low DCGF diet (L-DCGF) in which 10% of the same corn silage was replaced by DCGF, 3) a medium DCGF diet (M-DCGF) in which 18% of the same corn silage was replaced by DCGF, and 4) a high DCGF diet (H-DCGF) in which 25% of the same corn silage was replaced by DCGF.
