Correlations Among Yield and Composition of Milk of Angus-Holstein Cows and Consumption and Growth Rate of Progeny¹

Department of Animal Science, The Pennsylvania State University, University Park 16802

ABSTRACT

Milk production of Angus-Holstein F₁ cows was greater than most previous estimates for cows of beef breeding. Milk consumption from pre- versus post-suckling weights, was more highly correlated (0.63, P < .01) with calf gain than was either milk yield (0.49, P < .01) or solids-corrected yield (0.54, P < .01). A prediction equation of six milk characters accounted for 53% of the variance in calf gain. An equation of solids-not-fat percentage and 12-hour milk consumption accounted for 49% of the variance in calf gain.
