The effect of genotype and feeding level on feed efficiency for maintenance was examined during pregnancy and lactation in Hereford (H X H), Aberdeen-Angus X Hereford (A X H) and Friesian X Hereford (F X H) cows (n = 41) calving in autumn of 1985 and 1986. Cows were fed at 3 levels (maintenance (M), M x 1.25 and M x 0.75) during the final 8 weeks of pregnancy and 2 levels (M plus feed for 4 kg or 8 kg milk/cow daily) during the first 8 weeks of lactation.
