SPRAYCOX II — a field-proven machine used for spray vaccination in the hatchery — has been retooled to allow easy application of vaccines for respiratory diseases and coccidiosis.
Originally, SPRAyCOX II was developed to administer Merck Animal Health’s COCCIVAC and PARACOX coccidiosis vaccines at the hatchery. Although it could be used to administer vaccines for Newcastle disease (ND) and infectious bronchitis (IB) vaccine, SPRAyCOX II needed to be fitted with a plastic hood, power box and syringe delivery system — a time-consuming job for hatcheries.
The solution: Replace the plastic hood with one made of stainless steel. Technicians also added a disposable-syringe delivery system that includes one dual block with two 10-cc disposable syringes set to spray 21 cc and one disposable plastic syringe check valve that attaches to the front of the disposable syringe.
The 10-cc syringes, which are widely used and readily available in the industry, can be pulled back to 10.5 cc so that 21 cc can be obtained from the two 10-cc syringes, he explained.
Other improvements include quick-connect tube fittings and a new stainless steel aeration tube. The unit’s two power boxes have been replaced by one double stainless steel power box to house all electrical and pneumatic components.
With these changes, new SPRAYCOX II units arrive ready to spray the ND-IB vaccine and a coccidiosis vaccine; the units are also easier to operate and maintain. Older SPRAyCOX II units already in place at most major poultry companies can easily be retrofitted with the upgrades in about 30 minutes.
The enhancements to SPRAYCOX II were developed by associate customer-support specialist Jerry Green and equipment specialist Tim Milam. For more information, producers should contact their Merck Animal Health representative.
