Impact of Parasitism

Direct Damage:

• Diarrhea

• Respiratory disease

• Death

Indirect Damage:

• Secondary bacterial infection

Poor Animal Condition

•Dietary defeciency (Vit. A,B & B12),

  Various minerals and proteins

  predispose to heavier infection.

•Egg production decreases

Effective parasite control can be achieved by:

Step 1: Preventing parasite transmission between Broodhen and her chicks

“Clean up the Broodcock/Broodhen and you clean up the flocks”

Step 2: Preventing re-infection in the range and cord area.

De-worming Program

What Benefits do we get from Pakyaw®?

-Ensures non-transfer of worm population from 1 flocks to another as all stages are affected

-Infected animals regain health & appetite quickly- Fast Recovery is achieved

-GUT-ACTIVE thus Full-action is applied in the Intestines

-Complete control of Worm Infection

Fast facts:

-A great variety of worms infect free-ranging or game fowls.

-In caged chickens, worms are not a major cause of disease.

-Certain parasitic worms are still present and may add to economic loss.

-Many of these worms have intermediate invertebrate hosts such as insects or earthworm.

-Others have direct life cycle with no intermediate hosts involved

Most common worms of Game birds

Worms of the respiratory tract

-Syngamus trachea à causes the condition called “gapes” in chickens. 

-Affects the trachea and blocks the airway leading to difficult breathing à stretched neck with open mouth.

-Fr. Egg become infective in 17-20 days

Intestinal roundworms of chicken

Capillaria spp. – “threadworm”

-While smallest of the nematodes, can be highly pathogenic when present in large numbers.

-Different species of capillaria affects different parts of the digestive tract.

-They may have direct or indirect life cycle. Earthworm is the common intermediate host.

-Worms are found by careful examination of mucosal washings under microscope.

-Fr. Egg- IH (earthworm) become infective in 14-21 days

Hetarakis gallinarum – cecal worm

-Very common in chickens. 

-Probably  not pathogenic but may cause blockade when present in large number.

-Prepatent period 24-30 days.

Ascaridia spp.- large roundworm

-Largest roundworm of birds

-Adults live in lumen of small intestine

-May cause ill-thrift, enteritis and intestinal impaction.

-With direct life cycle (eggs become infective

    in 10 days)


-Many tapeworms affect the avian species. 

-However, most are of low pathogenecity.

-Most require intermediate hosts à flies, beetles, ants

Tapeworm Life Cycle:

-Gravid proglottids (segment w/ eggs) in feces

-Ingested by various beetles & houseflies(intermediate host)

-In IH develop eggs into cystecercoids (18 days 25-30°c) at lower temp.3-4wks.

-Single beetles/housefly can carry upto 1,000 cystecercoids-will mature to adult after 11-13 days.(12-13 cm) 32-43 days

Some de-wormers for poultry

Fenbendazole: How does it work?

-Inhibit cell microtubule of worm cells but not of chickens. Microtubules important in worm’s development and nutrition 

-Inhibit development of eggs and larvae into adult worms 

-Block nutrient transport in the worm then the  worm dies of starvation

-Only slightly absorbed from gut à therefore more contact time with worms.

-There is no known incompatibility with nutrients, feed additives and other drugs.


Dosage for chickens is as follows:

-For ascarids - 10 mg to 50 mg/kg once, repeat in 10 days, oral 

-For Microfilaria (including eyeworms) – 10 to 50 mg/kg, oral 

-For Capillaria – 10 to 50 mg/kg, oral; 

-For  tapeworms and gapeworm (Syngamus spp.) use 50 mg/kg 


-Broad spectrum.  Effective against major helminths in poultry.

-Eliminates all stages of infestation from ova to adult!

-Safe to use.  No need for fasting!

-Gut active.  Full-action is applied in the intestines!
