Abstract

Groups of animals were exposed to 1 of 8 by-product feedstuffs for 15 minutes daily. Each animal's consuming time was scored. Stable intakes occurred after intervals ranging from 2.3 d for whey permeate to 6.4 d for brewer's waste. Sulphuric acid whey and mother liquor were not accepted. Familiarising the animals with the pens and feeding procedures, and reducing social dominance effects resulted in increased consumption. Mixing a low preference feed in increasing proportions with a highly acceptable feed can result in cows eating previously rejected products. By this means cows were changed from concentrated deproteinised lucerne juice or corn steep liquor (highly acceptable) to mother liquor, brewer's waste or cheese whey (less acceptable) in from 5 to 15 days.
