Wheat Middling Versus Alfalfa Hay Supplements for Lactating Beef Cows Wintered on Ammoniated Wheat Straw

Effects of shearing and supplemental level on intake of dry ewes grazing on barley stubble.

Twenty-eight Comisana dry ewes were utilised to evaluate the effect of shearing (14 shorn and 14 unshorn ewes) and supplemental level (100 and 300g of concentrate) on intake of barley stubble. Shorn ewes showed a small increase in dry matter intake (at the end of August: 1.32 vs. 1.10kg/day; p<0.01). Intake of barley stubble decreased as supplement level increased (mean: 1.18 vs. 1.29; p<0.01)....
