Elevated atmospheric CO2 will change the requirements plants have for minerals, mainly nitrogen, altering the relationship between nutrient demand and plant growth. Here, we evaluated the interacting effects between two concentrations of CO2 (390 or 750 µL L-1) and two nitrogen (N) levels (3 mM o...

The effect of a sub-clinical fascioliasis infection on feed intake, OM digestibility (OMD), N retention (NRET), rate of BW changes and lamb birth weight was studied in 23 open and 17 pregnant Menz ewes. The infection was imposed by oral dosing with Fasciola hepatica in pregnant and open ewes. All...

The study aimed at examining the effects of replacing urea with protein nitrogen (N), source of protein and the quantity of rumen degradable N (RDN) in the diets of steers on rumen fermentation, outflow rate and intake. In experiment one, six ruminally cannulated Friesian steers were used in a re...

Foliage of four multipurpose trees (Calliandra calothyrsus, Chamaecytisus palmensis, Leucaena diversifolia and Vernonia amygdalina) and a woody leguminous perennial (Lablab purpureus) were evaluated for their potential as protein supplements for sheep fed maize stover ad libitum. The chemical c...
