US: Mineral requirements to be discussed at conference
Don Mahan, a swine nutrition expert will present some of his recent studies on addressing proper mineral nutrition at the Midwest Swine Nutrition Conference in Indianapolis, Indiana on Sept. 4.
The paper, “A New Approach in Determining the Micro Mineral Needs of the Growing Pig,” highlights how the current NRC recommendations for micromineral supplementation are well above the pig’s requirement. One conclusion from his studies is that when mineral levels at or above 50 percent of the NRC (1998, 2012) requirements were fed, there was no effect on pig performance.
Mahan’s paper also indicates that organic trace mineral digestibility values averaged 20 percent greater than the digestibility of inorganic trace minerals. Mahan said that it is important to not only look at the mineral levels that are being fed to pigs, but also the source of the minerals. Organic trace minerals offer a form of supplementation that can be more naturally absorbed, stored and utilized by the animal.
Though there has been limited new research carried out in the area of trace mineral nutrition recommendations, Alltech has remained steadfast in the investigation of the nutritional benefits and appropriate levels of organic trace minerals for animals and their effects on the consumer and environment. To that end, Alltech has partnered with scientific experts, such as Mahan, in the investigation of trace mineral technology.
The National Research Council (NRC) routinely publishes a review of the nutritional requirements for swine based on the available scientific literature; however, Mahan said that the relevance of most of the published literature is questionable, particularly in the mineral area.
Alltech will once again be a sponsor of the Midwest Swine Nutrition Conference held annually since 2000.
