Comparative effects of mesquite alkaloid extract and monensin combined with cottonseed on clinical and metabolic parameters, and rumen microbiome of lactating dairy cows

Key Points

• Lactating dairy cows showed improved clinical parameters when treated with mesquite alkaloid and monensin, indicating potential better health outcomes.
• The analysis revealed significant changes in metabolic parameters, particularly in feed efficiency and rumen function, suggesting enhanced nutrient absorption.
• Observational assessment of rumen microbiome showed a notable shift in microbial populations associated with the dietary interventions, indicating shifts in microbial diversity.
• Findings imply that using mesquite alkaloid and monensin in dairy diets could enhance overall health, though further work is needed to confirm long-term benefits.
