Goats have poor natural resistance to worms.
You've noticed they prefer to browse shrubs & eat from a height. Once their food has touched the floor - instinct says 'don't eat it', it might be contaminated with poo & worms.
Recommended testing frequency: 4 times per year
Highest risk periods: after flooding, kids
Goat WEC: £12.50
for up to 5 named samples
Including fluke, coccidia and lungworm
This can be a mix&match of species across the farm

controltips
Good parasite control is about more than using a drug every 3 months,
you can reduce risk & use of anthelminthic drugs:
-
do not graze with sheep (they share worms)
-
do graze with horses (they 'hoover-up' goat worms)
-
Avoid previously flooded grazing
-
Avoid mud-snail areas, eg by streams
-
Encourage foraging behaviour
-
Feed hay in a rack, never the floor
-
Feed plenty of tree leaves
-
Ensure access to tree bark
-
Rotational graze
-
Increase dietary protein in kids
-
Ensure new animals have a clear FEC
-
Be fastidious with food bowl cleanliness
Focus On: Coccidia
The dreaded coccidia!
Why is it such bad news?
This tiny parasite (Eimeria) infects the gut lining of young kids & lambs. The initial inflammation causes severe diarrhoea.
This inflammation then permanently scars, the animal will always be a 'Poor-Doer'.
The biggest problem - this scarring starts before shedding coccidia in faeces, so a positive test in a sick kid is already too late.
To add to this complex bug's trouble - healthy adult sheep & goats will have a normal population of coccidia living in their bowels - giving a positive test result when nothing is wrong.
As if that all wasn't bad enough - the treatment is difficult. No drug kills all the parasites. Decocquinate, Lasalosid and Monensin and Diclazuril will all help to reduce parasitic load, and should be used to treat in-contact kids & lambs.
Diclazuril (Vecoxan) can be given to all lambs or kids at 4-6 weeks of age on farms known to have a coccidia problem.
To add insult to injury - the bug is extremely difficult to kill in the environment. Sunlight & Ammonia are the only two things to kill this bug reliably.
The key to Coccidia Sucess? Prevention is Better than Cure.
Symptoms
-
Kids & lambs 1-6 months old
-
Brown, watery diarrhoea
-
Blood & mucus in faeces
-
Poor appetite
-
Dehydration
-
Weakness
-
Rough coat
-
Weight loss
-
Fading away & death
Treatment
Affected Kids:
-
Vecoxan 0.25mls / Kg by mouth, repeated after 3 weeks
-
Aggressive fluid therapy - orally with electrolyte solutions and/or subcutaneous saline
-
Antibiotics for secondary infection
-
Hand feeding
In contact kids:
-
Vecoxan 0.25mls / Kg by mouth, repeated after 3 weeks
Cleaning
-
Clear away all faeces & bedding
-
Try to encourage as much natural sunlight as possible - coccidi are killed by UV light
-
Get kids & lambs outside as soon as possible
-
Reduce stocking density
-
Clean everything with an ammonia based cleaner, eg superkill max.
-
Change water buckets daily
Prevention
-
Control build up of manure or waste
-
Ensure good natural daylight
-
Maintain low stocking densities indoors
-
Keep water sources totally clear of faecal contamination
-
Clean indoor housing with ammonia before the start of lambing or kidding season
Known coccidia environments:
Treat kids & lambs with vecoxan (or similar coccidia treatment) at 4 weeks old, and at times of stress - weaning, moving
