[Jacob-list] Heat loss

[Neal Grose]

Heat stress losses can be extremely complicated and involve several factors. 
Our sheep generally do fine here, even with full fleeces, with 90+ degree 
heat and 80% humidity, but piling on other things can do them in.
1) Worm loads. We have both summer dormant and winter dormant strains of 
parasites. A sudden improvement in climate conditions can cause a sudden 
hatch-out of worms.
2) Clostridia infections can take hold during stress and internal injury 
(such as worms) and cause sudden death...as in healthy to dead over-night.
3) Mild poisoning. Sheep are lazy, especially during heat, and may just not 
feel like walking past the deadly nightshade, jimsonweed seedling, draught 
stressed lambsquarter....nitrate, prussic acid ...all can be deadly when 
sheep (or cows) are already under stress.

Interesting. I have mentioned to folks that Nomads in the desert use wool
hooded caftans to stay cool.  Lynette mentions the sheep having good wool on
them to protect them from the desert. Instinct seems to say take the wool
off, but I think possibly, this is counter intuitive: they NEED the wool to
keep cool. Is that your experience, Lynette?

I'm sorry to hear your loss. I just had a ewe turn up spontaneously with
acidosis with no feed change. Only change was weather. She survived with
quick treatment. My sheep have no access to shade, and the weather here is
usually 100-115 in the summer. Been in the high 90s a lot this year. The
only time I worry about shade is when it is over 105. The sheep seem to do
fine with the heat as long as they have good wool on them, and a ton of
water in large enough tanks to stay cool. If anybody has one turn up heat
stressed probably wouldn't hurt to check for acidosis? Might be related At
least its treatable. Makes a very distinguishable slosh in the rumen. I know
that culling for heat stress is helpful as well from a desert dwellers
perspective.

Good luck with the heat, and the drought. I hope your weather comes around.

Has anyone had any heat related deaths. I found my ram dead in the pasture
on Friday and i have no idea why..... he was fne in the morning, UTD on all
his vaccines and had a FAMCHA check recently.... (nice and pink). He was
shorn in late may, had access to plenty of water, (both natural stream and
stock tank). I had been noticing on the severly hot days he was a bit
distresses but everyone's been distressed with all this 100 + degree
weather.
?
He was a really nice ram :-(?? ...................

Did he have shade available? My Jacobs have been laying in the shade during
the hottest part of the day  coming out to graze in the early mornings and
late evening. I have had no deaths. We did put  gallon milk jugs filled with
water and frozen in the water tanks on those 100 degree days so the water
would not get hot. Sorry for your loss.

We lost one of our favorite older ewes a few weeks ago due to heat. It was
the fifth day of 103+ degree heat on our farm, and it finally took a sudden
toll. Our sheep had lots of shade and water, and most of them tolerated it
fine, but this ewe was still nursing 2 big lambs, and must have just got
over-stressed. She was very suddenly lethargic for one afternoon (at which
time we made sure she was shaded, cold watered, fed, and we even gave her a
dose of antibiotic), and the next morning we found her dead. The same day
we lost three rabbits. Not a good day.

This year has provided some crazy weird challenges. Heat is one, but the
dryness here in Michigan has been another. The ground here is so dry that
my high tensile electric fence basically was useless because the ground is
so dry that it doesn't ground well... no electrical ground = no effective
electric fence. Suffice to say the ram lambs had it figured out and were
helping themselves to the neighbor's high grass for several weeks until I
was able to reestablish authority (ha).

just a weird year.
