Age-of-dam adjustment factors for birth and weaning weight records of beef cattle: a review

J. M. Rumph and L. Van Vleck, D., Age-of-dam adjustment factors for birth and weaning weight records of beef cattle: a review, vol. 3. pp. 1-17, 2004.

Age-of-dam adjustment factors are used to preadjust birth and weaning weight data for national beef cattle genetic evaluations. Adjustments are used in order to make the means of the different age-of-dam subclasses similar so that a fair comparison of animals can be performed. A review was made of various research studies that have estimated age-of-dam adjustment factors for birth weight and weaning weight of beef cattle.
