Effects of linseed processing method (ground versus extruded) and dietary crude protein content on performance, digestibility, ruminal fermentation pattern, and rumen protozoa population in growing lambs

Thirty-six male lambs (averaging BW = 24.4 kg) were assigned in a completely randomised design with the factorial arrangement (nine lambs per each treatment) to assess the effects of linseed processing method (ground vs. extruded) and dietary crude protein content (12% vs. 15%, DM basis) on performa...
