• Phosphorus: Ruminal Availability and Effects on Digestion ...

    Summary. The availability of P for ruminal digestion in vivo from a monodicalcium phosphate containing 21% P (monodical), a monodicalcium phosphate containing % P (dical), and defluorinated rock phosphate was compared with sodium phosphate (Na 2 HPO 4 ·7H 2 O). Monodical, dical and defluorinated rock phosphate were found to be 88, 62 and 40% as available as sodium phosphate .
