Next webinar: Join the Q&A Session with Professor Dr. Santos

A recent study led by Dr. Jose Santos has brought remarkable insights into the use of hydroxychloride trace minerals in dairy cows' diets, yielding substantial improvements in several key performance metrics. Transitioning from conventional sulfate-based minerals to hydroxychloride-based sources of copper, zinc, and manganese yielded notable benefits, including a 2% improvement in feed efficiency, a 19% increase in colostrum production, a 1.5 kg (3.3 lb) rise in energy-corrected milk (ECM), and a significant 12% reduction in culling rates. These findings underscore the potential of hydroxychloride minerals in advancing herd health, productivity, and overall profitability, particularly during the critical transition period of dairy cows.

The study, conducted over a 105-day lactation period, highlighted how hydroxychloride minerals improved feed efficiency, performance and health of dairy cows. Part of the improved feed efficiency may be related to the fact that hydroxy trace minerals act differently within the cow’s digestive system compared to sulfates. Hydroxychloride-based trace minerals exhibit lower ruminal solubility, reducing the release of free ions that can negatively impact the rumen’s microbial environment. The reduced release of free metal ions in the rumen could result in enhanced fiber digestion, and as a result, the cows fed hydroxychloride minerals could be more efficient.

Dr. Santos’ study suggests that hydroxychloride trace minerals may contribute to better nutrient retention in tissues and reduced disease susceptibility, particularly around the calving period. The results show a compelling connection between enhanced mineral bioavailability and improved health, as cows receiving hydroxychloride minerals exhibited better early lactation outcomes. Colostrum yield rose by nearly 19%, delivering more critical nutrients to calves, while the cows also achieved a 1.5 kg higher ECM yield during the entire study period which lasted until 15 weeks into lactation. These findings suggest a promising strategy for dairy producers aiming to optimize feed efficiency and lactational performance and to improve cow longevity by reducing morbidity and culling rates.

Dr. Santos will be discussing these findings in an upcoming webinar on November 18, where attendees will have the opportunity to delve into the practical applications of his research. Subscribers are encouraged to submit questions in advance on the benefits of hydroxychloride minerals and the broader implications for dairy cow management.

The session promises a deeper look into how strategic mineral supplementation can address common health challenges and support sustainable productivity in dairy herds.

The digital Q&A session takes place on Monday, November the 18th, 15:00 CET / 14:00 UTC.
