SOME FACTORS AFFECTING THE INTAKE OF ROUGHAGE BY SHEEP

Abstract

The dry‐matter intake of silage was increased when the silage had a higher dry‐matter content and when the time of access to the silage was increased from 3 to 24 h. Concentrate supplementation had a greater influence in depressing the intake of hay than that of silage. Only a small difference was observed in the replacement of hay by concentrates when the concentrates were given with two hays of different dry‐matter digestibility. Concentrates with a relatively high protein content depressed roughage intake to a lesser extent than concentrates with a low protein content.
