Standardizing Hay Palatability Trials with Calves

University of Wyoming, Laramie

ABSTRACT

A study of the hay consumption of 34 Holstein calves from 3 to 12 months of age showed that consumption followed hay allowance over a wide range of weight and age. When the hay allowance was increased by 1 lb. daily, the coefficient of variation in consumption of three types of hay ranged from 1 to 3 per cent, the standard deviation ranged from 0.4 to 0.8, and the standard error between 0.5 and 0.2. Because of this small variation, hay palatability trials may be standardized to give comparable results over a period of several years by simply comparing hay consumption with a set hay allowance even though there may be a variation in weight for age and in grain consumption.
