Unlocking Potential: Improve Your Broiler Performance with Jefo Protease

In the world of poultry farming, boosting feed efficiency while ensuring animal health is key to economic success. With raw material prices soaring, enzymes like Jefo Protease have become game-changers. A study conducted by the Federal University of Rio Grande do Sul in Brazil highlights its remarkable benefits for broiler chickens. Let's dive in!
Why enzymes matter
Enzymes are revolutionizing how we feed broilers. By enabling diets with reduced protein levels, they slash feed costs and reduce nitrogen waste, addressing environmental concerns. Yet, finding the right balance is essential: reducing protein while maximizing efficacy to achieve consistent animal performance.
The groundbreaking study
This study evaluated four dietary treatments to assess the impact of Jefo Protease on broiler performance under both standard and low-protein diets (a 6% reduction in crude protein and essential amino acids, based on Brazilian Poultry and Swine Table recommendations). A four-phase feeding program was tested over 42 days, analyzing intestinal health and performance. On day 28, ileum samples were examined using the I See Inside Scoring System Methodology. Curious about the findings?

Key discoveries
Performance:
- Protein reduction challenge: a 6% cut in dietary crude protein negatively impacted body weight and feed conversion ratio.
- Jefo Protease: supplementation successfully mitigated these effects, delivering growth performance comparable to birds on the standard protein diet.
Gut Health:
- Birds supplemented with Jefo Protease demonstrated significantly better intestinal health (ISI index), particularly in parameters such as lamina propria thickness, epithelial thickness, and proliferation of enterocytes.
- These results align with multiple published studies positioning Jefo Protease as a key component in broiler diets—enhancing growth performance, reducing feed costs, and boosting intestinal health.
The Bottom Line
Jefo Protease is a flexible, high-value solution. It optimizes performance in standard diets and becomes a strategic tool in low-protein diets, reducing feed costs without compromising performance results. Plus, it enhances gut health, adding even more value to broiler nutrition.
