Intestinal health, immunity and profit in modern dairies
Milk yield, fertility, and resilience don’t start in the parlor—they start at the intestinal barrier. We sit down with Dr. Elliot Neto, Dairy Technical Service Manager at Kemin North America, to unpack why gut integrity is the hidden driver of modern dairy performance and how a leaky barrier quietly siphons energy, components, and profit. From calves with permeable, naive guts to fresh cows facing intake swings and heat stress, we connect the physiology to practical decisions that make or break the lactation curve.
We walk through the core stressors that challenge the intestine: inconsistent colostrum delivery, abrupt weaning, pathogenic pressure from E. coli and Salmonella, transition-related drops in dry matter intake, and rising heat stress that redirects blood away from the gut. Dr. Neto explains the cascade when tight junctions fail—LPS translocation, systemic inflammation, and glucose diverted from milk to the immune response—translating into lost kilograms of milk per day, poorer feed efficiency, and higher disease risk. The message is clear: protect the barrier and you protect the balance sheet.
Then we get tactical. We dig into strain-specific probiotics—especially characterized Bacillus subtilis—that deliver three proven modes of action: pathogen inhibition via antimicrobial metabolites, inflammation reduction through signaling control, and quorum quenching to block pathogen communication and biofilms. For calves, that means fewer scours and steadier intake; for transition cows, stronger barriers, better DMI, improved liver function, and higher peak milk. We also discuss Kemin’s research frontier: genomic strain mapping, metabolite profiling, biomarkers like circulating LPS and tight junction proteins, and functional nutrition with targeted amino acids and postbiotics.
If you’re ready to stop chasing gut problems and start building resilience, this conversation gives you the roadmap and the why behind it. Subscribe, share this episode with your nutritionist or herd manager, and leave a review telling us the one gut-health change you’ll implement this season.
