Brookside Agra Introduces All-Natural GP Pro+ Acidified Nutritional Protein Supplement

Brookside Agra is now offering all-natural GP Pro+, a high-quality acidified nutritional protein supplement research-proven to improve pig and sow feeding performance.

GP Pro+ contains key nutrients including digestible sources of peptides, amino acids and trace minerals, such as:

  • 79% crude protein
  • 70% soluble protein
  • 12% lysine
  • 5% TDN

Using a preparatory stabilization and acidification process, GP Pro+ is unique in its quality as a feed ingredient and is highly stable with moisture under 5% and a pH around 3.

“GP Pro+ has none of the anti-nutritional factors that can be in plant-based protein sources,” said Tim Nelson, Vice President – Animal Health & Nutrition Sales at Brookside Agra. “When incorporated into a balanced diet, GP Pro+ drives feed intake, leading to optimal growth, condition and health.”

In a recent study, naturally-raised weanling pigs whose diets contained GP Pro+ ate more feed and gained more weight compared to the control group in field trials, which lasted 49-51 days.

Field Trial Results

  • Increased Intake: 15.18% more feed consumed
  • Increased Gain: 10 pounds (17.54%) higher average finished weight
  • Better Health: Reduced scouring
  • Death loss reduced from 8% to 1.33%
  • Increased Return on Investment (ROI)

GP Pro+ is spray dried and packaged in the United States under strict FAMI-QS, Safe-Feed/Safe-Food, HACCP and Identity Preserved Standards.
