All-Natural ProMin Specialty Feed Additive from Brookside Agra Formulated to Regulate Mineral Absorption for Peak Performance

For over 70 years, animal feeds have been supplemented with trace minerals which are essential for animal health, growth, lactation and reproduction. Absorbed easily into an animal’s system, Brookside Agra’s all-natural ProMin proteinated trace minerals can “up regulate” or “down regulate” the amount of minerals absorbed, therefore helping the animal reach its peak performance level.

Research has proven that organic trace minerals better fit an animal’s trace mineral requirements by providing better availability when the animal needs them. Trace minerals also provide a greater potential of increased stability when subjected to varying PH levels.

Animals have systems that regulate the amount and form of the nutrients and metabolites they absorb and utilize. Animal nutritionists have discovered that the more accurately they supply the needs of the animal in terms of diet and environment, the more efficiently the animals will perform.

“The pH of the gastrointestinal tract ranges from 1 to 2 in the stomach and can go up to 7.2 as digesta moves through the digestion process. It is particularly important to have a trace mineral that will survive this pH shift and the digestive degradation attempts until reaching the target absorption site. ProMin proteinated trace minerals provide a greater potential of increased stability when subjected to varying pH levels. The multiple bonds in ProMin increase the potential for utilization by the animal,” said Tim Nelson, Brookside Agra Vice President – Animal Health & Nutrition Sales.

Trace minerals are potentially toxic to all life, but absolutely necessary as well. Too much can kill and too little can also kill. The absorption architecture in animals must work very well and respond rapidly to changing supply and demand during periods of varying growth, stress and disease.

The ProMin manufacturing process mimics Mother Nature because organic minerals are made the same way that the animal does when it eats and digests its feed. The animal gets some organically complexed minerals in the food they eat but most are broken down by enzymes and pH during digestion. The animal then rebuilds the minerals into organic forms so that the minerals will remain soluble and be able to easily move to the sites of absorption as digestion proceeds. The animal’s system is designed to appropriately handle minerals in this manner.

Adding minerals to the diet of deficient animals in a form that is already prepared for transportation to the site of absorption improves the probability that the animal can get the necessary minerals when they need them. ProMin is recommended for all types of livestock and poultry.
