Amino Acids
Perdue Animal Nutrition is committed to improving the profitability of the dairy producer by providing quality and consistent feedstuffs. Milk components drive milk income and increasing amino acid supply can increase milk component yield.
Methionine, lysine and histidine are key amino acids for maximizing milk protein yield. Additionally, recent research demonstrates that leucine, along with isoleucine, is key for maximizing milk and milk protein yield. Blood meal is high in digestible lysine, histidine and leucine. Rumen-protected methionine can be added to allow for formulation of a nutrient dense product that supplies all key amino acids needed by a lactating dairy cow.
At Perdue Animal Nutrition, we take pride in supplying consistent quality products. Our quality control and assurance program ensure that supply of metabolizable amino acids is the same load after load. Our range of high-quality protein products allow you to select the product that best blends cost efficacy with amino acid balancing.
