Focus is on providing the required pet food quality at lowest possible operating costs and with specific attention to:

  • Precise feed composition
  • Highly consistent pet food pellet quality regarding size, shape, surface, color, and density
  • Highly consistent pet food pellet absorption and retainability of liquid fat and digest ingredients
  • Consistent and uniform pellet dryness
  • Processing with careful attention to protection of essential nutrients
  • Optimization of energy consumption

We know what we are getting when we ask for it. I don't have to follow-up or make sure the part is correct. I know it will always be correct, and I know it’s going to last a long time.
