Extract

Synchronising the rate of rumen breakdown and availability of dietary energy and nitrogenous components can improve the capture of rumen degradable nitrogen and improve the amount and efficiency of rumen microbial protein synthesis. It is not clear what influence rumen synchrony has on nutrient use by the portal-drained viscera (PDV). This experiment has examined the impact of feeding two diets formulated to be asynchronous or synchronous with respect to the potential hourly supply of energy and nitrogen to the microbial fraction of the rumen on portal blood flow, net flux of ammonia and urea across the PDV and arterial insulin concentrations.
