Abstract excerpt

This study explored the associations among phenotypic, reproductive, nutritional, and metabolic traits with early sexual development in Bos indicus heifers. A total of 443 prepubertal Nelore heifers (11.1 ± 0.07 mo old) were evaluated during a feedlot (automated feeders) period from day -70 to day 0. Parameters assessed on day -70 (beginning of the feedlot period) included body weight (BW), body condition score...
