Worm infection is Grazing problem ofworms eggs contaminated pastures
IN Punjab No Grazing Land is available for animals
Our 80% Livestock is keptby small Dairy Holder under chain in clean premises in side or near family
And these animals have No chance to get infection in contaminated pastures / or fodder taking L3 stage
Larvae ofround worm that require a specific favorable condition / temperature to hatch out from worms
eggs on grazing area / fodder and Liver flucks infection also require intermediate Hostand meracidium on
fodder or grazing area. In Punjab less than 20 % Livestock have grazing area while other Livestock feeding
on fresh fodder without any contamination of worms eggs.
The Following 3 stages ofLarvae (after hatching worms eggs) require to getinternal worm infection for
grazing sheep and cattle’s on contaminated pastures (as shown in below fig.)
3-Host stage,,,,,,,L3 stage in Hoststage require 18 days with favorable weather condition on specific
temperature and humidity for developmentand survival on grazing grass ofpastures .
While Weak condition livestock in field is considered case ofworm infestation with
recommendation ofDeworming by our Vets, or by farmers themselves withoutjustification and
without Lab, test actuallysuch cases are misdiagnosedin under fed animals on mal-Nutrition that is
very common in field.
In advance countries havinghuge Livestock like Holland/ Australia/ Newzeland/ Sweden etc.with
huge Pastures with free fodder
In these countries thecontaminated pastures with worm eggs are problem having the above 3
condition favorablewith ideal temperature / ideal humidity for worm Eggs hatching todevelopinto the
L1 and L2 and L3 stage that is after about on 18 days hatching of worms into larvae whenweather
conditions are favorable for survival on pasture grass and engulfed L3 stage Larvae during Grazing
of animalsto get infection.
In these countries, Deworming is planned on seasonal control, Deworming recommendation for
cattle at the right times and to reduce the worms for an entire season.A strategic deworming
program reduces the parasite burden on the pasture and in the herd in these countries
Sheep are more susceptible to internal parasites than most other types of farm livestock for
several reasons. Their small fecal pellets disintegrate very easily thus releasing the worm
larvae onto pastures. They are also less of a problem in arid regions, because parasites
require moisture for their development.The fecal counts only estimate the parasite load,
there is no clear cut level at which deworming is indicated.
As a general, a level of more than 500 EPGeggs per gram of feces
would indicate that dewormingis needed.
A more effective way of deciding when to treat would be to monitor fecal every 4-8 weeks
when there is a dramatic rise in egg counts the Deworming is required when animals are in
