Purina Animal Nutrition introduced new research data on Rally Dairy Feed that shows milk production benefits during heat stress. As a nutritional heat stress abatement measure, the patented feed technology allows the delivery of more glucose and energy to cows than a typical diet when intakes are challenged, according to the company.
Research results, including two field demonstrations, showed that incorporating the feed into transition and lactating cow rations has benefits that may protect profitability potential, feed intake and milk production.
In field demonstration A, cows fed Rally Dairy Feed during heat stress showed 3.5 pound increase in dry matter intake and 7 percent improvement in feed efficiency.
In field demonstration B, the feed delivered a milk production benefit of 8 pounds per day during the first 15 weeks of lactation during heat stress conditions.
Transition cow studies conducted at the Purina Animal Nutrition Center have also shown that when this group was fed the product, it delivered:
- Higher peaks in milk production
- Higher total milk yield over lactation
- Reduced non-esterified fatty acids (NEFA) levels by 15 percent
- 27.6 percent reduction in beta-hydroxybutyrate (BHBA) PD
