Q: Is there anything that a grower needs to do to make the Al+Clear® Liquid A7 application more effective? show answer
A. There are several things that are important in order to insure that an application is successful and effective:

  • Timing of application is important. Al+Clear® Liquid A7 should be applied 2-3 days prior to placement of baby chicks.
  • Litter conditions should dictate application rates. Ask you regional technical sales representative for assistance in determining the proper application rate for differing litter conditions.
  • The contract grower should be at the farm at the time of the application if at all possible.
  • Lights should be on in the house during the application.
  • End doors should be left open unless it is raining.
  • Pre-ventilate prior to the application. Either turn fans on minimum ventilation in advance of the application to get ammonia levels to a safe level for the application [20 ppm] or turn on two tunnel fans for 10 minutes to purge the house of ammonia prior to the application.
  • Cut fans off during the application to prevent the possibility of creating turbulence that might result in overspray.
  • If the application is only performed in the brood chamber it is vitally important to drop the center curtain and equipment as soon as possible after the application to prevent ammonia from the off-end of the house rolling over onto the treated brood area. It is also important to go into minimum ventilation as soon as the application is performed. It is important to pull air from the brood end of the house to the off-end fans and exhaust. Not following this procedure can dramatically reduce the effectiveness of an Al+Clear® Liquid A7 application.
  • Keep in mind that litter amendments are not a substitute for proper ventilation. It is recommended that the contract grower adhere to the integrators ventilation policies regardless of the effectiveness of the ammonia control. Moisture has to be eliminated from the broiler house and without adequate early ventilation, litter conditions can deteriorate rapidly causing a variety of husbandry problems.
