Direct and maternal genetic effects on preweaning characters of Brahman, Hereford and Brahman-Hereford crossbred cattle



Direct and maternal genetic effects on preweaning characters of Brahman, Hereford and Brahman-Hereford crossbred cattle



Journal of Animal Science 63(2): 438-446



Data on birth weight, preweaning gain and weaning weight (adjusted 180-day weight), collected over a 20-yr period for 451 Brahmans, 127 Herefords and 229 Brahman-Hereford crossbreds, were analysed for genetic differences. Preweaning gain was calculated as adjusted 180-day weight less birth weight. All statistical models included effects of dam age, year, season and sex.
