Product Description

Chlorsol 50 is administered to broiler chickens and pigs for the treatment and control of infections due to susceptible bacteria.


  • Chlorsol 50 is used in the treatment and control of colibacillosis secondary to infectious bursal disease, chronic respiratory disease caused by Mycoplasma gallisepticum and Escherichia coli, Salmonella enteridis, Salmonella typhimurium and Pasteurella multocida infections.


  • Chlorsol 50 is used in the treatment and control of respiratory diseases associated with Mycoplasma hyopneumoniae, Streptococcus suis and toxigenic strains of Pasteurella multocida. It is also used in the control and treatment of rhinitis due to Bordetella bronchiseptica and streptococcal meningitis due to Streptococcus suis type II.



Dosage & Administration

Chlorsol 50 is recommended for oral administration in drinking water. For the 2kg pack a level scoop contains approximately 20g powder.


  • 200 g of product should be dissolved in 600 L of drinking water and administered daily for up to 5 days. This will provide a daily dosage of 20-50 mg Chlortetracycline HCl/kg depending on water consumption.
  • Dosage may be adjusted to up to 60 mg/kg depending upon the severity of infection, by careful calculation of the total bodyweight of the birds and dissolving the requisite amount of Chlorsol 50 in the quantity of water consumed within 24 hours.


  • In order to achieve the recommended dosage rate of 20 mg Chlortetracycline HCl/kg, 200 g of product should be dissolved in 500 L of water and administered daily for up to 5 days. This will provide medication for 5000 kg of pigs.
  • Allowance for wastage of medicated water and reduced water intake should be made and the necessary adjustment made to the amount of product used.
  • Medicated water should be prepared daily and any unused water should be discarded safely.

Chickens and pigs should have access only to medicated water during treatment.
