MPWV Meat Goat Producers Association
MPWV Meat Goat Producers Association
Spring Conference
March 20, 2004
President, Dick Dixon opened the meeting, by welcoming everyone and invited those that are not currently members to join the association.
Parasite Management Update – Susan Schoenian - Maryland Cooperative Extension
Susan pointed out that no new drugs are available, but the treatments have changed.
Parasite Susceptibility
Goats and Sheep are more susceptible to internal parasites then cattle, swine, or horses.
Youngsters are more susceptible than the older ones.
High producers, high stress animals are more susceptible than low production, low stressed animals
Skinny animals are more susceptible than those that are fat
Grazing animals more than zero grazing
Grazing more susceptible Browsing
Heavy stock rate more than light stocking
Intensive rotation grazing with shorter rest periods more than low intensity, rotational gasing with longer rest periods
Normal or abundant rainfall more than drought
Summer and Fall are greater than Spring and Winter
Drugs are FDA approved for goats
Safegaurd
Rumitel
Tape worms
Valvasen
Safeguard
Lice or biting parasites
Ivomec
Mydectin
Highest level of resistance
Ivomec
Valvasen
Safeguard
Seem to still be working
Tramisol
Moxidectin
Quest
Internal Parasites Realities
Haemonchus contortus – Barber pole worm
Blood sucking parasite causes protein loss to the host
Symptoms – pale mucous membranes, bottle jaw, rarely diarrhea, death
Difficult to control
Short direct life cycle
Other stomach worms
Trichostrongylus, Ostertagia, cooperia
Direct life cycle
Burrow in the wall of the abomasums
Causes scouring
Life cycle as short as 7 days
Other parasites
Tapeworms
Tend to be non-pathogenic
Treat with benzimidazoles
Indirect life cycle
Lung worms
Direct or indirect life cycle
Controlled b same anthelmintics as stomach works
Liver flukes
Treat wth Albendazole
Requires open water snails
Coccidia
Major problem
Different control program
Additive with feed and minierals in feed or water
Meningeal worm (deer, brain worm)
Parasite of white tail deer
Keep away from wet areas
Larva travel from intestinal tract to spinal cord
Lameness, gait abnormality paralysis death
High does of anthelmintics
Anti inflamittory drugs
Parasite control starts with good management
Good sanitation
Never feed on ground
Clean water, free from fecal matter
Proper stocking rates in pens and pastures
Always isolate and deworm new animals to a farm
Clean or safe pastures
New pasture
Pasture that has been renovated
Not grazed for past 6-12 months
Pasture in hay or silage crop
Pasture that has been rotated with row crops
Mixing species of livestock
Sheep and goats share the same internal parasites but not cattle or horses
Producers who graze multiple species fewer parasites
Intensice rational grazing
Rotational grazing does not reduce parasites unless rest periods are long
Nutrition and worms
Higher nutrition better body condition – less prone
Increased protein during late stages of pregnancy – reduces parasites
Zero Grazing
Confinement to eliminate worms but need to treat for coccidia
Genetics and worms
Some breeds more resistant
Varies between animals (Nubian, boers)
20-30% due to genetic factors
Cull worm-susceptible to increased flock resistance
Resistance – ability to host eggs
Resilience -Ability to withstand challenge infection and productivity of parasites
Resistant breeds )brush goats, Spanish, Myotonic, Pygmy, Kiko
Not resistant - Boer, Dairy (Nubian, saaean)
Drugs
Three Families
Benzimidazoles – Fenbendazole (safeguard or Panacur), albendazole (valbazen), Oxybendazole (synanthic)
Broad spectrum
Safe
Effective against tape worms
Nicotinics – levamisole (tramisol, levasole, prohibit)
Broad spectrum
Effective against arrested larvae
Narrower margin of safety
, Motatel rumatel (premix),
Stongid (pyrantel)
Clear drench
Macrolides – avermectins, ivermectin, doramectin
I
Only approved fenbendazole and Morantel are FDA approved for goats
Cydectin – for cattle – use orally for goats
Make sure using with the consultation of a vet
Stategic deworming
Treat prior to kidding
Treat and move to clean pasture
Start of grazing season
Mid summer
Fall treatment
Prior to breeding
Targeted therapy
Kids
First time mothers
Highest producers
Leave some goats untreated to slow anthelmintic resistance – “rufugia”
Maximize the single treatment
Do not unerdose
Put it behind the tongue
Fast before
Use higher doses
Weigh the animals
Treat with antehlmintics
Compare FEC at the time of treatment with counts 7 to 14 days
>90 effective
60-90 Moderate
