Measurement of feed intake and feed efficiency in feedlot cattle.

Dorothy L. Robinson, JW Skerritt, VH Oddy

Abstract

Measurement of feed intake is repeatable even over short periods, but estimates of weight gain are not. Given measurements of intake over a relatively short period (7-9 weeks including time to adjust to the automatic feeding system), a more reliable assessment of efficiency was achieved by relating feed intake to gain modelled using a growth curve based on all weights recorded in the feedlot, instead of simply using weights for the period when intake was recorded.
