    Abstract:
    Postweaning, feedlot, and carcass data from crossbred calves sired by five Bos indicus breeds and one Bos taurus breed were evaluated. Data included records from F1 calves out of multiparous Hereford cows sired by Angus, Gray Brahman, Gir, Indu-Brazil, Nellore, and Red Brahman bulls. The Zebu crosses grew faster postweaning and were heavier and taller as yearlings than the Angus crosses (P < .05). Among the Zebu-sired calves, the Red and Gray Brahman crosses were faster gaining and were heavier at a year of age than the Gir, Indu-Brazil, and Nellore. The Nellore crosses were significantly taller than the Gray Brahman- and Gir-sired crosses; the Indu-Brazil and Red Brahman were intermediate. Angus crosses were lightest on and off feed but were not significantly different from Gir, and Red and Gray Brahman were heaviest (P < .05). The Nellore and Indu-Brazil were similar in initial weight, but Indu-Brazil calves were similar to Red and Gray Brahman for final weight. The Angus cross was more desirable (P < .05) in marbling score and quality grade although the Nellore crosses had the most desirable score and grade of the Zebu crosses. Gir crosses had higher skeletal maturity scores (P < .05) than Nellore, Gray Brahman, Indu-Brazil, and Angus crosses; Red Brahman crosses were intermediate Angus crosses had the lightest carcasses but not significantly lighter than the Indu-Brazil, Gir, or Nellore. Red Brahman-cross carcasses were heaviest and Gray Brahman-cross carcasses were intermediate.(ABSTRACT TRUNCATED AT 250 WORDS)
