Fish Flour as a Protein Source in Calf Milk Replacers

Abstract

Substitution of varying levels of fish flour protein for skimmilk protein in calf milk replacers was studied in growth and balance trials, using 108 Holstein calves. The effect of dietary fat on growth responses to fish flour also was investigated. Milk replacers (diluted to 15% dry matter) furnished the only source of nutrients to calves in growth and balance trials.
