Guanidinoacetic acid (GAA) is a key precursor of creatine in skeletal muscle, where it plays an important role in ATP regeneration and protein synthesis. Therefore, the objective of this study was to evaluate the effects of dietary GAA supplementation on growth performance and carcass traits of feedlot Nellore cattle...

Tylosin and monensin are commonly included in high-grain feedlot cattle diets to improve growth performance and feed efficiency. However, increasing concerns regarding antimicrobial resistance highlight the need to develop alternative strategies to reduce reliance on antibiotics. A more mechanistic understanding of h...

A more mechanistic understanding of how antimicrobial supplementation (Tylosin plus Monensin) affects the ruminant gastrointestinal tract (GIT) in high grain diets may help accelerate the development of effective antibiotic alternatives. Previous work in swine has demonstrated that tylosin supplementation alters bile...

This study evaluated the effects of essential oil (EO) blends on physiological responses of feedlot cattle before transport (d 57), immediately after transport (d 65), and following a 4-week recovery period (d 92). Thirtytwo cross-bred heifers (265 ± 25.9 kg) were blocked by body weight and assigned to one of four tr...
