When should deworming treatments be scheduled for outdoor Desi and brown layer flocks relative to the monsoon season in Pakistan?

Outdoor-housed Desi and free-range brown layers are highly vulnerable to internal parasites like tapeworms (*Raillietina*) and roundworms (*Ascaridia galli*). The optimal timing for anthelmintic (deworming) therapy is heavily dictated by seasonal rainfall. In Pakistan, deworming must be scheduled approximately 2 weeks prior to the onset of the summer monsoon (typically mid-June), as the rising humidity and wet soil will soon trigger a massive hatch of parasite eggs and intermediate hosts (like beetles, earthworms, and snails). A secondary deworming dose must be administered 4 weeks after the monsoon season ends (late September) to eliminate any adult worms that developed from larvae ingested during the wet period. Farmers can read parasitology manuals in the Poultry Encyclopedia, buy piperazine or levamisole-based dewormers on Poultry Plaza, track weekly Desi bird rates on Poultry Rates, and list dewormed free-range flocks on Murghi Mandi.
