Maintaining Normal Gut Health Early Pays Long Term Benefits

Recently published data in the Journal of Animal Science, reported by Bovine Veterinarian in June 2026, reveals abnormal stools in young dairy heifer calves cost dairy producers future lifetime milk production.

Results show that this long-term negative impact hits first lactation, second lactation and accelerates during third lactation. Not just in pounds of milk and peak milk production, but also in decreased milk fat and fat-to-protein ratios, impacting quality parameters as well.

Key data on those that experienced neonatal diarrhea vs. healthy calves (305-day milk yield):

First Lactation = 1,457 lbs. less milk

Second Lactation = 633 lbs. less milk

Third Lactation = 2,396 lbs. less milk

Utilizing the 3-year average Class III FMMO milk price of $17.63/cwt., this can amount to $790 per cow in lost revenue over 3 lactations.

Key conclusion from the authors: “Our research revealed that calf diarrhea is a critical early-life health challenge, with consequences extending beyond the calf period to significantly affect lactation potential. Our findings underscore the need for early-life interventions to mitigate lactation losses in high-parity herds.”

Based on this new data, it is time to rethink the assumption that an abnormal stool in 25% of dairy heifer calves under 3 weeks of age, only costs extra labor and money during that time period.

Start today by increasing focus and investment in the first few weeks of life to help maintain normal gut health and deliver added revenue in the future.
