Dr. Vincent Habimana pursued his PhD research in the Department of Animal, Aquaculture, and Range Sciences at the College of Agriculture, Sokoine University of Agriculture. His study, “Evaluation of Heat Stress Effects on Milk Yield Traits and Metabolites in Dairy Cattle Reared in the Tanga Region, Tanzania,” demonstrates the potential of integrating physiological, metabolic, and genetic markers to enhance the resilience of dairy cattle under heat stress. By identifying biomarkers and assessing genetic diversity in Tanzanian herds, the research provides practical tools and models for sustainable breeding, improved productivity, and can lead to climate-smart livestock systems in tropical regions.
Heat stress is one of the most pressing challenges to dairy production worldwide, particularly in tropical regions where high temperatures and humidity prevail. In Tanzania, the Tanga region represents a critical case because of its rapidly growing dairy sector, dominated by crossbred cattle that are especially vulnerable to heat stress. Dr. Habimana’s research examined the effects of heat stress on milk yield, composition, physiological responses, and genetic resilience, with the goal of identifying biomarkers of tolerance and developing strategies for genetic improvement to help farmers adapt to climate change.
