Abstract:

Five Angus × Hereford cow s with ruminal and duodenal fistulas were used to evaluate the effect of providing increasing degradable intake protein (DIP) o n the site and extent of digestion of dormant, tallgrass-prairie forage. The DIP was provided from sodium caseinate, divided in two equal portions and infused intraruminally twice daily. Levels of DIP were: 0, 180, 360, 540, and 720 g/day. Supplemental DIP generally improved utilization of low quality forage, with maximum effects on duodenal N flow and forage organic matter intake at 540 g DIP/day.
