The Availability of the Phosphorus in Alfalfa Hay1

G. P. Lofgreen and Max Kleiber

University of California2

Abstract

A study is described in which the true digestibility of the phosphorus in alfalfa hay is determined using five lambs as experimental animals.

It was found that an average of 88 percent of the fecal phosphorus of lambs fed alfalfa hay was of metabolic origin and 12 percent was undigested phosphorus from the hay.

While the apparent digestibility of the phosphorus of the hay averaged 22 percent, the true digestibility was 91 percent, indicating that the phosphorus in the alfalfa hay used in this study was highly available for absorption by lambs.
