Abstract: The paper by RE Hickson, ST Morris, PR Kenyon and N Lopez- Villalobos published in the New Zealand Veterinary Journal 54, 256–264, 2006, entitled, “Dystocia in beef heifers: A review of genetic and nutritional influences” contained an error in the final paragraph of the final section (Summary and implications, Page 262) in which the word “heavier” should have read “lighter”. The correct paragraph is: “The effect of nutrition in late gestation on the incidence of dystocia has been variable, and neither low nor high feed allowances have consistently affected rates of dystocia or birthweight. This is possibly due to confounding effects of body condition and feeding level in early pregnancy and their influence on placental development. Studies in adolescent sheep revealed that high levels of feeding in early gestation resulted in lighter lambs at birth. More research is needed to determine the relevance of nutrition in early gestation to the growth and development of the fetus and placenta in cattle.”
