Trace minerals play an essential role in the immune system and providing it in a more available form can support an efficient immune response, as observed in both beef and dairy cattle16,17. Researchers at North Carolina State University and Ohio State University concluded that these glycinates had a positive effect on immune parameters in challenge conditions16,17. An effective immune system supports health and efficient performance throughout the animal’s full production cycle. Superior bioavailability of B-Traxim 2C compared to traditionally supplemented inorganic sources in swine, poultry and cattle has been shown consistently. For instance, in an unpublished trial conducted at the University of Wroclaw in Poland, sows supplemented with a reduced dose of organic trace minerals (50% from glycinates) had increased the average birth weight of piglets and significantly increased re-breeding success. Moreover, piglets with the higher average birth weight also showed improved daily gain, improved FCR and higher lean meat on carcass compared to lifetime performance of piglets from sows supplemented with inorganic mineral sources. Ultimately, greater bioavailability enables animals to better meet their nutritional requirements to optimize growth performance, support immunity and reproductive performance, as well as a reduction of mineral excretion. These outcomes are better for the animal and the producer’s bottom line. CONCLUSION Supporting weaning animals in their development through early nutrition is necessary to have a positive impact on all following production phases. Producers can take a three-pronged approach to overcome common challenges faced by young mammals. By improving feed palatability, supporting gut resilience and immunity, and ensuring all nutritional needs are met, calves and piglets will be quicker to wean and will have what it takes to finish strong.
