Making decisions about feed is complicated in the present day by high feed prices, and by the many byproducts available with uncertain nutritional value. As well, cutting feed costs will not necessary increase profit if revenue decreases as well, or if pigs require longer until market. Agribrands Purina uses an OptiPork system to help customers find feed solutions. The technology lets you input your own farm as a virtual farm, and assesses nutritional requirements, ingredient valuation, and profitability. Ingredient valuation tools include a laboratory, database, particle size measurer, and a system to calculate nutrient levels. The Purina Central Lab analyzes samples, and adds their profile to the database. Animal requirements are based on sex, feed intake, lean growth, and environmental conditions. OptiPork can help evaluate nutritional requirements, and make dietary decisions easier for producers.
