Purebred Brahman cattle spent significantly more time grazing in the pasture while purebred Angus cattle remained in the shade, not grazing, for most of the day. Other sires had steer progeny on the opposite end of the range. The 1.8 square inches of ribeye per 100 pounds of carcass indicated these Brahman steers had adequate muscling relative to carcass weight. Also, a purebred English cow will become stressed at 85 degrees F where a Brahman cow has a much higher stress zone at 105 degrees F (Dr. Todd Thrift, UF/IFAS). At the end of the day, cattlemen need to profit from their quality cattle and there are opportunities out there. The traditional stereotype for cattle with high Brahman influence has been that the meat is too tough. The breed also contributes to hybrid vigor when crossed with Angus and Hereford breeds. You take an animal like that and put him in south Louisiana, and it feels like its going to die.. The temperature humidity index is an indicator of heat stress and combines both temperature and humidity in a single measure. Research as show that hybrid vigor most affects traits related to efficiency. As a result of hybrid vigor, crossbred females have 10% greater fertility, 5% greater calf survival, 12.5% greater weaning rate, 70, greater calf weight at weaning, and 37% greater longevity compared to purebred females (Thrift and Thrift 2003). We hope by the end of this four-year project we will have a very good understanding about the neuroendocrine differences between Bos taurus and Bos indicus-influenced heifers, he said.
