Heat stress is a major constraint affecting dairy cattle productivity in tropical regions, leading to reduced milk yield, metabolic imbalance, and increased disease susceptibility. This study investigates the role of gut microbiome modulation using a synbiotic formulation in improving heat stress resilience in lactating dairy cows. A total of 40 Holstein-Friesian crossbred cows were divided into control and treatment groups over 60 days during peak summer conditions. Physiological parameters, milk yield, and ruminal microbial diversity were assessed. Results showed significant improvements in rectal temperature regulation, feed intake, and milk production in the treated group. Microbiome analysis revealed increased abundance of beneficial bacteria such as Lactobacillus spp. and Bifidobacterium spp. The findings suggest that microbiome-targeted interventions can serve as a sustainable strategy to mitigate heat stress in dairy cattle.
