Flubenvet 1% – 60g Packs For Worming Chickens

The backyard poultry market is growing rapidly but many novice poultry owners are unaware of simple preventative health routines that can significantly improve the health and wellbeing of their birds.

Don't Be ChickenWorms are not always visible and infection can be asymptomatic but worms can also affect egg quality and yield – fewer, smaller, paler, brittle eggs can result. Affected poultry can suffer ill thrift, anaemia and even death. The non-specific nature of the condition can make it hard for novices to identify.

Sources of infection

Embryonated worm eggs resist disinfectants and can survive for years.

Sources include:

  • An infected bird excreting thousands of worm eggs daily
  • Contaminated soil or litter material
  • An intermediate host (wild bird, earthworm or beetle)
  • Fomite transmission: footwear, equipment or other animals.

Free range and deep litter husbandry systems increase exposure to parasitic worms and may favour worm egg survival. Active infections of the common worms affecting poultry: Ascaridia (roundworms), Capilliaria (hairworms), Syngamus trachea (gapeworm), Heterakis (small roundworms) and Amidostomum anseris (gizzard worm) in geese need to be controlled through effective preventative and strategic de-worming programmes.

There is more information here on our page about worming poultry.

Where to Buy Flubenvet

Buy Flubenvet Layers Pellets60g packs of Flubenvet 1% contain enough to treat around 20 large fowl and you don’t need accurate scales to measure the quantity as you would with the 240g Gamekeeper packs. Premixed Flubenvet with Layers Pellets are also available which removes the need for any mixing too.

Update July 2015: Both packs of Flubenvet are unavailable at the moment from the manufacturer.

Premixed Flubenvet with Layers Pellets is still available here
(unless the feed mill runs out of Flubenvet!).

Treatment guidelines

Preventative health routines

At each treatment use Flubenvet® in feed for 7 days as directed:

  • Worm all new poultry when introducing to the flock
  • Before introducing the flock to pasture
  • The whole flock spring, summer and autumn as a preventive

Available in a 1% 60g pack sufficient to treat around 20 chickens

Active infections

Random worming may not be effective because worm eggs in the environment are a source of ongoing infection for a number of years.

Strategic programmes:

  • Prepatent Periods

    Take into account the pre-patent period of common poultry worms

  • Rely on treating at intervals shorter than the prepatent period until infection pressure is reduced, as measured by a reduction in faecal eggs per gram (EPG) counts
  • Once infection pressure is reduced, regular treatment will help keep the level of adult egg laying worms in the birds to a minimum.

Strategic de-worming

In the face of active infection, at each treatment administer Flubenvet® in feed:
