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

ALL IN ALL OUT BROILER FARM

ZOONO ANIMAL HEALTH CASE STUDIES

  • STUDIES CARRIED OUT IN BROILER SHEDS  FROM NOVEMBER 2018 – MAY 2019

 

  • EACH STUDY IS CARRIED OUT THROUGHOUT CONSECUTIVE GROWING CYCLE – 42 DAYS

 

STUDY 1  

  • A SINGLE SHED TREATED WITH Z-71 AFTER STANDARD SANITISATION

 

 STUDY 2  

  • COMPARING TWO SHEDS, TREATED AND UNTREATED.

 

  • DRINKER LINE AND FOOD BOWLS WERE ADDED TO THE ATP TESTING LOCATIONS.

 

  • ATP READINGS AFTER STANDARD SANITISATION THEN EVERY 10 DAYS THEREAFTER 

 

 STUDY 3 

  • READINGS TAKEN AFTER STANDARD SANITISATION, MID POINT AT 21 DAYS AND FINAL READINGS AT 42 DAYS

STUDY 1

THE BEST PERFORMING SHED ON THIS FARM

 

• WEIGHT GAINS APPROX + 50 GRMS

 

•  APPROX 7 TONNE LESS FEED CONSUMED

 

• SHORTER RUN TIME -  38.6 DAYS

• FCR  4 POINTS IMPROVEMENT ON COMPARABLE  UNTREATED SHED.

STUDY 2

AN UNTREATED SHED WAS INTRODUCED AS A DIRECT COMPARISON TO THE TREATED SHED.

IN ADDITION TWO FURTHER ATP LOCATIONS WERE TESTED,  FEEDER AND DRINKER BOWLS.

 SHED A - UNTREATED 

  • TREATED WITH FORMALIN

  • INSTANT LOW BACTERIA LEVELS AFTER STANDARD SANITISATION PROCESS

  • HIGH LEVELS OF CONTAMINATION WITHIN FIRST DAYS OF CYCLE.

  • PARTICULARLY CONCERNING LEVELS ON FEED AND DRINKER BOWLS

 

 SHED B – TREATED

  • MAINTAINED ALMOST ALL FOOD GRADE BACTERIA LEVELS THROUGHOUT CYCLE

  • APPROX 9 TONNES LESS FEED CONSUMED 

  • INCREASED WEIGHTS

  • SHORT CYCLE AT 38 DAYS

  • FCR COMPARISON AT 4 POINTS IMPROVEMENT TO UNTREATED SHED.

STUDY 3

SHED A – UNTREATED

  • TWO HIGH MICROBIAL READINGS IMMEDIATELY AFTER STANDARD SANITISATION.

  • HIGHLY CONTAMINATED THROUGHOUT THE CYCLE

SHED B – TREATED

  • CONSISTENTLY LOW ATP READINGS THROUGHOUT THE STUDY CYCLE.

  • APPROXIMATELY 11.388 TONNES LESS FOOD CONSUMED IN COMPARISON TO OTHER UNTREATED SHEDS.

  • FCR OVER 5 POINT IMPROVEMENT TO UNTREATED SHED.

CLIENT FEEDBACK

  • "Sceptical at first that something you can spray in your mouth could be more effective than conventional sanitisers."

 

  • "The ATP readings don’t lie and the sustained low levels of microbes in the shed is reflected in improved overall bird performance."

 

  • "The trend indicates savings of at least 10% of feed per run, increased bird weight and simply better performing birds in the treated shed."

 

  • "Farm personnel can be in the shed unprotected whilst misting occurs – ECO FRIENDLY."

 

  • "This technology is a big part of the solution for reducing the microbial levels in a shed."

BENEFITS AND ADVANTAGES

  • Improved FCR’s –  ranged between 3 to 5 points in the treated shed.

  • Shed sanitisation after water blasting is optional and has no effect on the performance of Z-71.

  • Z-71 is non hazardous ensuring the health and safety of farm staff and contractors.  

  • Non hazardous, staff can operate in the shed at all times. 

  • No increase in stand down time between runs with Z-71 in a reduced microbial  environment.

  • Arguably in a Z-71 treated environment no reduction in birds / KGs per SQM required therefore productivity can be maintained.
