530. The relative feeding value for milk production of two National Cattle Foods

Abstract

A feeding trial of the relative value for milk production of National Cattle Food No. 1 and National Cattle Food No. 6 is reported; forty-two first calvers were employed. The two foods were shown to be of very similar feeding value for heifers giving two to four gallons daily, the difference between them being slightly in favour of the N.C.F. 1. Each pound of this food produced 0·109 lb. more milk than the same amount of N.C.F. 6, but this difference was statistically without significance.
