    Research suggests zinc supplementation prior to transport can benefit cattle welfare, performance

    AMES, IA – Beef cattle are likely to be transported at least once during their lives and are often moved several times at different stages of production. During each transition, they may travel for hours, standing in moving, vibrating trailers. Not surprisingly, during the hours and days post-transit, fatigued, stressed animals tend to eat and drink less and are more susceptible to disease.  

    Research led by Stephanie Hansen, professor of animal science at Iowa State University, is investigating the potential of boosting zinc levels before transport as a low-cost, easy way to ease animals’ muscle fatigue during transit, improve their health and increase their long-term growth.
