LOW feed intakes can occur when too much straw is fed in dairy cow diets, warns Derbyshire-based Genus consultant Stephen Brook.
He has seen poor intakes on two farms when high dry matter, high quality grass silage was fed to cows with over 1kg of straw. Cows affected were at all stages of lactation.
"Too much fibre was going into the diet and by taking this out cow feed intakes have increased," he says. "But with more typical silage 0.5 to 1kg of chopped straw can be fed without affecting intakes."
