Walkover Teat Spray
Cotswold's Moojet Teat Spray is an automatic teat spray system using a floor-mounted stainless steel spray rail. It uses two spray nozzles in an offset pattern to optimise teat coverage.
-
Floor-mounted stainless steel spray rail -
Twin spray nozzles offset for optimal teat coverage
-
Spray initiated as cows approach the spray rail by infrared detector
-
Spray duration is adjustable to accommodate cow speed
Optimal Teat Coverage
While a walk-over teat spray cannot guarantee complete teat coverage consistently, proper installation and setup will ensure optimal performance.
Chemical Use
-
Increased chemical application results in improved teat coverage.
-
Standard teat spray gun: approximately 15mls per cow per milking.
-
Walk-over teat spray: approximately 40mls - 50mls per cow per milking.
-
Using more of a less expensive chemical is preferable to using less of a more expensive chemical.
Position
-
Consistent cow flow over the spray rail results in more accurate teat coverage. -
A properly designed race leading to the spray will promote a consistent and even flow of cows.
-
Correct race width is essential to position cows directly above the spray nozzles
-
The spray rail should not be installed near sort gates, foot baths, gateways, or windy areas, as these will disrupt cow flow.
Pre-Milking
-
Walk-over teat spray is well-suited for pre-milking use.
-
Accuracy is not critical, as the chemical will be wiped off before milking.
-
Ample application of inexpensive chemical yields good coverage.
-
Time between spraying and wiping allows for sufficient bacterial kill time.
Post-Milking
-
Good teat coverage is crucial.
-
Effective post-spray chemicals are expensive.
-
Expensive chemical and high usage rate results in high cost.
-
Most common issue: Restricting chemical use to reduce costs.
