Break out session 3 of 3

Basic Health Program Consideration for Shepards
Biosecurity, Quarantine, Drenching, Core Vaccines, Diseases to watch out for
Speaker: Dr. Bill Shulaw (extension vet)

Biosecurity
When you buy animals ask about:
*Parasite Control Program
--dewormer use history
--strategy used
--dewormer resistance profile
*Scrapie
*Foot rot, contagious abscesses, Johnes disease, ovine progressive pneumonia OPP in sheep and CAE in goats

Pregnant Sheep
*Avoid mixing groups of pregnant ewes if possible to avoid mass abortions
*use isolation if at all possible
*mix groups when not pregnant
*Consider vaccines and feeding tetracycline for vibrio (campylobacter) and chlamydolphila

Quarantine procedure preferred is 60 days isolation (30 days minimum)
*testing during quarantine
--OPP & CAE
dont test if under 6 months of age may get inaccurate results
--Brucella Ovis
bacteria that affects testicles and fertility in rams (not goats)
found mostly in western USA
*Foot rot may be wise to assume you purchased it and foot trim and foot soak
foot rot is a bacteria it is not caused by damp conditions or lack of hoof care
it is solely transmitted animal to animal
most common disease in sheep
there are 20 sub types of foot rot some much worse than others
foot rot does NOT live in the soil for years that is a serious myth at most it is there a
couple of days
--foot soak: 10% Zinc Sulfate
*Quarantine Drench to help avoid introducing drug resistant worms
--isolate animals to barn, dry lot or a sacrifice pasture not used for other sheep
--use more than one dewormer class, one of which should be cydectin and the other
probably leamisole (Prohibit)
--manure sample worm egg counts should be negative prior to turnout with other animals
do sample 2-3 weeks after deworming
--release from quarantine onto YOUR INFECTED pastures
you want the animal to pick up your non selected worms
*Breeding soundness exam (BSE) for rams
-- 10-15% of unexamined rams may have some abnormality during the fall breeding
season; many more than that in hot weather (75%)
--it takes about 60 days from beginning of sperm production to availability in the
epididymus for breeding

Visitors
--control visitor access and provide foot covers and possibly coveralls in animal areas

Core Vaccines
Clostridium perfringens types C and D overeating disease
*toxoid vaccine
*antitoxin temporary (14 day) protection

Non-Core Vaccines
Tetnus (may be core in some flocks / herds)

Campylocbacter and Chlamydolphila for contagious abortions

Caseous Lymphadenitis only if you have an infected animal along with clean animals
--common in sheep and goats
--draining abscesses are the primary source of the bacteria that causes the disease
manage these infected animals carefully isolation and disinfection
--shear animals with suspected abscesses last
--ask shearers to disinfect equipment and provide your own shearing mat
--vaccine must be combined with sanitation and management

Foot Rot
--vaccine not currently available for unknown reasons in the USA
--only works if the serotype on your farm matches the vaccine serotype
--oil based and will cause a LARGE lump
--do not accidently inject yourself it will have the same large irritating lump in humans

Soremouth
--virus that is contagious to people
--virus will persist in the environment for a while (at least 6 months)
--vaccine is LIVE and capable of causing the disease in animals and people
--vaccine not recommended unless there is a history of the disease on the farm or in the
flock / herd or reasonable certainty of exposure (such as a show with a soremouth
animal)

Rabies
--vaccines for sheep but not labeled for goats (work with your vet)
--may be required for exhibition in some states
--may be justified in some flocks / herds to protect valuable genetics and humans
--a big concern for states Pennsylvania and East of PA due to raccoon rabies

Thank you Emily for this thread! It has confirmed a lot of our farm's practices for me. Like, not using chemical dewormers/anti-parasitics unless a fecal shows a load present - which thankfully, so far, we have only had fecals come back clean. *insert a "whew" face here* Good news, especially knowing that we have deer and moose that frequent our property.
I have copied off the various plants, fruits, etc mentioned on here as being safe and/or anti-parasitic to add to our list of things to make sure we have or add to their feed rations(like cinnamon - hopefully it makes their breath smell better too :lol: )
I haven't scrolled all the way through yet, so it may have already been mentioned, but you can add to those natural dewormers/anti-parasitics:
hemlock(tree, not plant), spruce, and garlic(especially helpful against ticks & mosquittoes).
Again thank you! I am always learning, and wanting to share what I learn :)

:D

Garlic was actually discussed (brought up by another participant) and we were told that there have been no scientific studies done that have found it to be anti-parasitic. Our extension vet did say that he had a colleague who did a private study and that she claimed it was mildly effective, but that was as far as he would go with it.

There is a lot of information here and it takes a while to digest it.

I plan to do my own private study next spring as I detailed in a post earlier.

I don't know of any official studies, but I do know that when we switched from putting Frontline on our dogs(worked well, but made the skin on their necks thick and leathery and would still find ticks on them{dead, but on them}) to giving them garlic we found no trace of ticks on them. So we figured it would have the same effect on goats. I know people that eat a LOT of garlic, or foods containing garlic, you can smell the garlic in their skin oils.
