A sound and balanced nutritional programme is an important contributing factor to overall equine health. Essential trace minerals each play specific roles at supporting your horse through the different life stages, from breeding and growth, through to achieving optimum performance and ensuring health is maintained in the older years.


More than 45 years ago, Zinpro Corporation pioneered the research and development of organic trace minerals to improve animal wellness and performance. This research proves that it isn’t enough to simply add ordinary trace minerals to a horse’s diet, as they often pass through without ever being absorbed by the animal. Zinpro Performance Minerals® are designed for optimum absorption, providing the highest trace mineral absorption in the industry. Research shows that supplementing equine diets with trace minerals from Zinpro Performance Minerals positively affects many vital functions in horses including: hoof condition, reproduction, joints and skeleton, skin and coat, immunity and feed digestibility.


McMillan Feeds contain Availa®4, from Zinpro Performance Minerals®, which is a scientifically formulated blend of organic zinc, manganese, copper and cobalt.


Availa®4 is built on a unique, patented molecule that consists of one metal ion bound to one amino acid ion – called a metal amino acid complex. Zinpro Performance Minerals are the most bioavailable trace minerals on the market, which means more of the minerals are absorbed by the animal to deliver their full benefit.


Essential trace minerals for optimum health
Breeding and Growth

The trace minerals in Availa®4 play important roles in reproductive health including conception and the development of a healthy foal. Zinc is essential for supporting the integrity of the reproductive tract, and sperm maturation and quality. Copper plays an important role in foetal central nervous system development, and manganese is required for foetal skeletal development.


For optimum growth, young horses require adequate amounts of the minerals contained in Availa®4 also. Copper is responsible for the formation of connective tissues such as tendons and ligaments, as well as bones and cartilage that lines joints. Zinc assists with cell division and protein synthesis for skeletal growth and repair, and manganese contributes to bone matrix development and maintenance.


Recent research found that young horses supplemented with Zinpro Performance Minerals® produced a more robust pro-inflammatory immune response than those supplemented with inorganic minerals. This response permitted an increase in collagen degradation, allowing timely joint-repair processes necessary for growing horses. More information on this study is available here.


Optimum performance is never reliant on just one factor, it is a combination of many variables all coming together at one time. Of the numerous contributing factors to high performance, nutrition is one not to be overlooked.


The minerals found in Availa®4 are essential for numerous functions that contribute to optimum performance, including muscle development, hoof integrity and bone maintenance. Nutrients such as copper, zinc and manganese are essential for promoting and maintaining healthy joints and bone. These minerals also contribute to antioxidant activity that helps to remove free radicals and protect muscles from oxidative damage that can occur as a result of exercise. Cobalt supports fibre digestion in the hindgut resulting in additional energy being available from forage. Copper also has benefits to coat health as it is important for the normal production and maintenance of skin and hair pigmentation, and is therefore essential for achieving that show ring shine.


McMillan Feeds not only contain appropriate levels of these nutrients to meet requirements if fed at the correct level, but they also include these nutrients in specific, highly bioavailable forms. These nutrients are provided by Zinpro Performance Minerals®, who are experts in providing bioavailable nutrients to include in feeds to allow maximum absorption and therefore optimum health for your horse.

By choosing to feed a McMillan feed, you are providing your horse with a complete balanced diet, as well as Availa®4 from Zinpro Performance Minerals® to supply premium nutrients for optimum performance.
