187. Maternal Guanidinoacetic Acid Supplementation Modulates Cellular Heat Stress Responses in Late-gestating Hanwoo Cows and Their Calves.
Guanidinoacetic acid (GAA), a precursor of creatine, plays an important role in cellular energy metabolism and antioxidant defense. Therefore, dietary GAA supplementation may help mitigate heat stress in late-gestating beef cattle. This study aimed to investigate the effects of GAA supplementation on calf birth weigh...
