Feeding Methods and Grouping Systems

Abstract

Studies of taste behavior indicate that precise nutrient allocation is never achieved by lactating dairy cows offered concentrates according to individual energy requirements and forages free-choice in conventional housing systems. Concentrate feeding via the milking parlor reduces precision of nutrient allocation even further. Studies of social and feeding behavior of cows in loose housing suggest that it is unnecessary to provide one free-stall per cow or bunk space for all cows to eat simultaneously if a complete ration is continuously available. The advantages of the complete ration system far outweigh the disadvantages. More attention should be given to social and taste behavior of cows as feeding and housing systems are designed. © 1977, American Dairy Science Association. All rights reserved.
