Inca Piperazine Solution is a liquid anthelmintic treatment for roundworm infestations in pigeons, poultry, and pigs. Piperazine is a long-established worming active that paralyses roundworms so they are expelled naturally, and is administered via drinking water for practical flock or group treatment.

Dosing through the water supply allows entire flocks or groups to be treated without individual handling — particularly useful for backyard chicken keepers, pigeon fanciers, and small-scale pig owners. Roundworm burdens can cause weight loss, poor condition, and reduced productivity; regular worming with an effective water-soluble product keeps animals healthier and more productive.

Piperazine has been used in Australian livestock and avian worming programs for many decades. Inca's liquid formulation is a practical, cost-effective option for smallholders needing a reliable water-soluble wormer that covers pigeons, poultry, and pigs in a single product.
