Summary

A cubed molassed sugar-beet pulp product containing about 3% urea and with added minerals and vitamins was evaluated in 2 continuous feeding trials over 8–10 weeks with cows in early lactation and which had previously been accustomed to receiving dietary urea. In one experiment 50% substitution of a cereal/vegetable protein mixture resulted in a depression in mean daily milk yield of about 0·8kg. In the second experiment, the concentrate contained about 30% dried distillers grains and in this case replacement of one-half with the supplemented molassed sugar-beet pulp product did not decrease milk yields. There were no significant effects on milk composition.
