The effect of the extrusion of canola oilcake meal (COM) and crushed sweet lupins (CSL) with molasses on the dry matter (DM) and crude protein (CP) degradability was determined in situ. Locally sourced (SOILL Moorreesburg, South Africa) COM and CSL,…
Lupins are highly degradable in the rumen, and do not provide enough bypass protein for high-producing ruminant animals. The effects of extrusion on dry matter (DM) and crude protein (CP) rumen degradability of Lupinus albus and Lupinus angustifolius were determined…
The effect of the stage of maturity on the productivity, chemical composition, and ruminal degradability of Napier grass (Pennisetum purpureum) leaves under irrigation was studied. Samples were collected at three stages of maturity, at intervals of four weeks starting from…
Fermentation in the rumen, measured by a steady state in vivo method, was compared to in sacco estimates obtained by different methods of calculation. These methods included a first-order model calculated over 24 h, a first-order…
Ruminal degradation of crude protein from feedstuffs was determined in steers that were fed diets based on either maize (whole, meal or flakes) or on by-products of the milling industry. In addition to the in sacco degradation study, fractional outflow…
