Animal Research and One Health, EarlyView.Nelore (N) and Nelore × Pantaneiro (NP) heifers exhibited similar grazing times, which were higher compared with Nelore × Angus (NA) heifers. Nelore heifers showed higher wither height and hip height values compared with NP heifers. The average values for NA heifers did not differ from the other genotypes. It was observed that chest depth, heart girth,
