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



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



Dissertation Abstracts International, B Sciences and Engineering 45(5): 1379



All models used in the study included effects of dam age, year, season and sex. Brahman dams produced calves with lighter birth weight than other calves. Brahman-sired calves were heavier at birth than calves with sires of other breed types. The estimated direct additive effect of the Brahman breed on birth weight was 4.6 kg greater than the corresponding Hereford effect. The Brahman maternal additive effect was 7.5 kg less than the Hereford effect.
