Abstract

This paper presents genetic parameters of insulin release after glucose infusion for possible use as an
 early predictor of dairy merit. Male and female calves were tested at 5 and 9 months of age using a bolus dose of glucose and serial blood sampling. Heritability estimate of PEAK insulin was 0.21, but that of BASELINE insulin was close to zero in pubertal male calves. The correlation of insulin PEAK at 9 months of age to progeny test results for fat (kg) and protein (kg) was positive.
