Intestinal Integrity (I2) scoring
The Intestinal Integrity (I2) score system is unique to HTSi and independently validated, I2 is proven to correlate with key performance indicators.

- Microflora imbalance
- Anti-nutritional factors (e.g. β-mannans)
- Feed/dietary factors
- Enteritis
- Coccidiosis
- Mycotoxins
- Farm/litter management
Improved I2 scores = improved flock performance
Intestinal function determines feed conversion efficiency, which drives the performance of birds. I2 consistently and reliably analyses broiler gut health via the assessment of 23 gut health lesions, resulting in a score between 1-100.
As I2 goes up by one unit:

ADG increases by 0.04g1

FCR decreases by 0.131 pts

EPEF increases by 0.521

% livability increases by 5%2

Reducing the risk of Heat Stress in Broiler
Modern broilers are at particular risk of heat stress1. Heat stress can occur at any age; however, it is more commonly seen in older birds when their growth and metabolic rates are at their peak.
