Feeding performance trace minerals is essential to maximizing the production performance of your dairy herd. To truly thrive, calves; heifers; and lactating, dry and transition cows must receive optimum trace mineral nutrition throughout each life stage.
Zinpro Lifetime Performance starts before birth, building a calf’s ability to mount a robust immune response. This will ultimately lead to better nutrient and energy utilization for growth, production and reproduction throughout the life of dairy cattle.
Improving A Calf’s Ability to Respond
Calves are born with limited immunity to disease. The first two weeks of life represent a high-risk period for calves, because their active immune system is not fully functional. Colostrum provides the calf with immunoglobulin (IgG) antibodies and other immune factors that are vital during the first few weeks of life.
During the first 12 to 24 hours after a calf is born, it is critical the cow transfers the maximum amount of immunoglobulin (IgG) to the calf through colostrum. Rich in antibodies and high in protein, colostrum provides nutrients that are essential to overall health, immunity and growth of the newborn calf. Increasing IgG levels in maternal colostrum through performance trace mineral supplementation aids in passive immunity to the newborn calf. Successful passive transfer of immunity through colostrum results in lower incidence of calf sickness and death.
Research shows that feeding performance trace minerals to cows throughout their lactation and dry periods increases IgG levels by 23.8 percent on average.
Reduce Milk Loss by Reducing Digital Dermatitis
Digital dermatitis in dairy cattle triggers an immune response that diverts nutrients away from milk production while also reducing feed intake. Research has shown that heifers with one digital dermatitis event produced 438 pounds (199 kg) less milk in their first lactation, while heifers with multiple digital dermatitis events produced 738 pounds (335 kg) less milk during their first lactation.
Managing Lameness in Dairy Cattle Improves Feed Efficiency and Milk Production
Performance trace minerals have positive effects in the small intestine, helping to increase absorptive surface and reduce leaky gut, along with improving mammary cell integrity during heat stress. Performance trace minerals also help with keratin formation, which strengthen epithelial tissue, promoting better hoof health. Improving epithelial tissue and hoof integrity reduces the immune system’s need for energy and nutrients, allowing more to be used for milk production. Research shows that feeding performance trace minerals results in a 34-percent decrease in white line separation and an 11-percent decrease in sole ulcers.
Animals that aren’t utilizing energy and nutrients for immune challenges, such as lameness or digital dermatitis, see an increase in feed efficiency. Research shows that feeding zinc from Availa® Zn at a level of 40 ppm increases feed efficiency by 9 percent.
Milk production can also be tied back to immunity. Research shows that feeding performance trace minerals results in 441 pounds (200 kg) more milk for first-lactation heifers and 604 pounds (275 kg) more milk per lactation in mature cows.
Performance Trace Minerals Improve Dairy Reproductive Performance
It is important for dairy producers to supplement dairy cattle nutrition with performance trace minerals during the dry period and prepartum period to improve reproductive performance. Research shows that performance trace minerals help cows return to ovarian function sooner, resulting in a 7 percent increase in pregnancy rates and a 13 fewer open days. Each open day can cost a dairy producer between $3 and $4.
