MEASUREMENT SCALES, TECHNIQUES, SCALE AND VALUES

ATP TESTING

The measurements were realized with ATP testing technology.  The measurement units are in RLU that is not a standardized unit of measurement. It depend of the monitoring systems, sensitivities, reagent formulations and light detection systems. 

RLU scales are different for each system. The most relevant aspect of the measurement is not the absolute value but the relative comparison, between sheds and on time. 

SCALE

RLU scales are different for each system. Each manufacturer sets their own value for 1 light unit and all measurements are made relative to that value. The scale defined by the manufacturer of the used equipment is:

VALUES

Average value: For each shed and for each measurement moment,  was obtained an average RLU value calculated as the average value of the two mid points from the six measured. The goal is to reduce the outliers. 

Relative difference: The relative comparison between sheds was obtained by calculation of the ratio in percentage between the average value obtained for each shed in the same date

POULTRY FARM TESTS 

INTRODUCTION

Test environment: inside 8 sheds were selected.

-4 control sheds (untreated) with no Z-71 applied

-4 sheds (treated) where Z-71 was applied 

6 locations for ATP monitoring

- 4 points in the walls

-1 drinker

-1 feeder

RESULTS: PROCESS AND DATA ANALYSIS

ATP READINGS

OBSERVATIONS: 

- One day after the Z-71 application, the average microbial reading (ATP) has significantly reduces in excess of 90%.

- Sheds treated with Z-71 show an over 90% reduction in microbial count compared to Non-Zoono treated environments.

This resulted in improved FCR's by up to 5 points.
