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. Four groups of cattle were fed a combination of soybean meal or pellets with or without straw. The cattle that didn’t receive straw demonstrated modified behavior. This group also experienced rumen lesions. On the other hand, cattle fed straw had a greater expression of genes involved in gut-brain crosstalk. This study posits that avoiding a low (more acidic) ruminal pH helps improve gut-brain communication.
