Read more about how researchers evaluated 7,500 lactating cows to evaluate the long-term effects of disease during the early postpartum period. Read

In this study, researchers made innovative use of endoscopy to sample rumen and colon tissues. This technique offered a unique perspective to study rumen microbiota. The resulting research details the effect of the rumen-specific yeast S. cerevisiae CNCM I-1077 on microbiota changes in both rumen and colon around transition. Read

Feeding sufficient amounts of colostrum in the first 24 hours of life is well-known to be vital for calf health. Less is known about transition milk feeding and the potential benefits. Read

In large, intensive beef production systems, the identification of sick animals can be difficult. Activity monitors may be able to help identify sick cattle earlier based on behavior changes. Read

Heat stress during the dry period has dramatic negative impacts on the cow and her offspring. Cows that experience heat stress in late gestation make less milk and are at greater risk of disease and nutritional issues. Read

Do cattle get “hangry” too? For some humans, lack of satisfying food options can negatively affect their mood and behavior. This study demonstrated a similar effect in cattle. Read

In this study, molecular markers of rumen development and gene networks regulating the rumen epithelium were identified. Read

In the future, we may be able to estimate dairy production using a “genotype × environment × microbial” interaction model that accurately combines all factors affecting milk production. Read

This research from the University of Guelph shows how the feeding behavior of dairy cows — including how, when and what cows eat of the feed provided to them — has a significant impact on cow health and productivity. Read

This study from the University of Florida, Gainesville, found that cooling for the entire dry period increased milk yield up to 30 weeks into lactation. It showed that heat stress at any time during the dry period compromises performance of cows after calving. Read
