The Soay Sheep Chronicles

Actually, it’s not an ounce, rather 2 cc’s, but “cc” doesn’t roll off the tongue quite as well, does it?

If by any chance you do not vaccinate your Soay against clostridial diseases, you should start now. This is one of the few areas where I cannot help nagging. The sight of an animal in the throes of tetanus is truly ugly and heart-wrenching, and easily preventable.

You can read about chilling vaccine, shaking it often, the nitty gritty of the actual vaccine on more technical sites. What you will not find on the pharmaceutical pages is how to make the process shepherd-friendly. Read on.

Scheduling. We follow conventional wisdom from other breeders and aim to vaccinate about 30 days in advance of lambing. On this schedule, the ewes’ immunity level is freshly boosted and their colostrum at the maximum level of antibodies for the newborn lambs. Plus, having a set calendar allows us to pretend our lives are in order, the same sort of harmless illusion of control we get by changing batteries on the smoke alarms each year when Daylight Savings Time kicks in.

Catching. Use your trusty grain bucket, the Soay shepherd’s best friend (well, maybe second-best after blue gloves), to get the ewes off the pasture and into catchpens. In case you doubt the effectiveness of a strategically-placed bucket of grain, have a look at Steve last Sunday doing his imitation of the Pied Piper.

Confinement. Tranquility is the goal here. The last thing you want is for general panic to set in; therein lies both madness and broken horns. Aim for the smallest possible enclosure.  We used to put all our girls into our 8 x 12-foot shelters and even they were too spacious. This time around we processed 5-7 ewes at a time in an enclosure no bigger than 5 x 4 feet made from our trusty Shaul panels, just room for the person giving the vaccinations. Since I was the paperwork processor and Steve was the hands-on guy, I will let him describe what he did.

“Once I get the ewes in a small space, I stand still among them, then calmly reach out and touch one of them, on her horn if possible, or around her neck. If they can’t go anywhere, they will accept my touch without undue alarm. What I want to avoid is anything that will start a chase. If they cannot run, they accept their fate.”

Seating the ewe. Working one standing ewe is enough to convince any sane shepherd that converting the ewe from a four-footed animal to a sitting duck is the only way to go when vaccinating. As the observer, it seems to me the key is to keep the ewe from lurching her head and arching her back, triggering flailing behavior. Once again, I will let Steve describe how it works for the person on the front line:

“The easiest way to get access to the vaccination site on the ewe’s chest area, right behind her foreleg, is to get her sitting on her butt or, better yet, slightly off to one side on her left ‘cheek.’  I have watched shearers do this and of course they make it look easy, especially that no-good rascal in Thornbirds. Unlike the big clumsy Suffolks, Soay are quick and adept at remaining upright.  But I have the advantage, their small size.  I just lift the ewe up until her back legs are dangling, then quickly drop her while moving slightly backwards so her hooves will point forward and she’ll land on her bum. For me it is most comfortable to let her left side rest against the inside of my left leg.”

Author’s note: where is the video camera when I need it?  Does anyone know how to post videos on a blog? Hrmph.

Injection-site lumps. Some sheep, perhaps one in ten, seem prone to develop marble-sized abscesses at the injection site. This is nothing to worry about except they look icky and you will fret about them no matter what I say.  It seems to help avoid the lumps if you are adept enough at giving injections that the needle lies almost flat between the skin and the body wall. Try not to go straight in like a “puncture.” Once you have given the shot, immediately rub the injection site for a couple of seconds, shmooshing the vaccine away from the hole.

Marking the finished ewes. By all means mark your ewes as you work them. It is the simplest way to be sure you have not missed anybody. We use the “All-Weather Paintstik Livestock Marker” made by LA-CO Industries, should be available at your local farm supplies store. One marker will last way beyond your Soay-raising lifetime if you do not leave it in your pocket and run it through the washing machine – yuk.  The slash of color on the ewes’ noses gives them a whimsical look right out of the circus clown tent, but it wears off in a few days, and who cares if they look like pregnant Bozos, anyway? Here is our fetching little tan ewe, Lime, with her pink forehead right after her vaccination last Sunday.

Extra credits. In the non-essential but useful category, we always bring along a ewe list to make sure everyone is present and accounted for. Almost without fail, we see something to make a note about, an issue needing attention or presenting a “new development” worthy of discussion over adult beverages after chores. Just this morning, in fact, I was downloading pictures to the OFP Gallery (see link over there on the right) and needed to confirm whether Millie is polled or scurred. Sure enough, there in the folder of old vaccination and worming lists was a grubby note I scratched next to Millie’s name the first time we worked her in late 2004: “tiny buttons.”

A closing note on dosages. We use Covexin-8. Its label calls for an initial dose of 5cc, with boosters thereafter at 2cc. On the advice of our veterinarian, we use 2cc right from the beginning on our lambs. Five ccs seems just way too much for a 10-week old Soay lamb.

Oh yes, did you remember to set your clocks ahead last night?

For now …

For generations before the internet replaced paper, boys happily frittered away countless hours on baseball cards, memorizing statistics and honing their negotiation skills.  At the same time, if they were lucky, they were introduced by their grandfathers, as Steve was, to the insanely arcane world of scorecards, meticulously recording the details of a game with their stubby little pencils and even stubbier little fingers.  No wonder Steve came up with the idea of lambing cards.
 
Like their baseball predecessors, lambing cards are both a luxury and a necessity.  You do not need them to produce healthy, marketable Soay.  But once you try them, you cannot get along without them.  And they are a lot easier to master than scorecards.  

The lambing card is nothing more than a 3 x 5 card with pre-printed information about each dam/sire breeding pair and blank spaces for the shepherd to capture the vital statistics for the ewe’s one or two lambs right after it/they arrive. 
 
You may ask, why bother with cards, why not simply annotate a list of your Soay as lambing proceeds?   We once used a spreadsheet on a clipboard and it was okay, but the clipboard had a nasty habit of falling off ledges into the muck and it was a total mess by midway through lambing.  Plus, finding our way across an 11-inch line of small type to be sure we record data for the correct ewe is exasperating, even if we remember to bring our reading glasses.  With cards, once we know which ewe lambed, we grab her card, stick it in the Lamb Kit, and we’re set to go. Besides, it is fun to shuffle through the deck in the evenings as we chatter about lambs born and yet unborn.
 
Every picture still tells a story even if Rod Stewart does not, so before I get any further wound up about lambing cards, let me show you what one looks like.  Here is our card for Cleopatra and her first lamb, Turmeric, in 2006:

A few notes on a few items.  The first box, Seq 2006-  tracks the order in which the ewes give birth.  Cleopatra was our 26th ewe to lamb in 2006.

OR119-028 is Cleo’s ear tag number.  We always double check the ewe’s tag once we get her in the jug with her lamb(s).     

BoSe in the upper right hand corner reminds us to give the ewe her shot of selenium and vitamin E supplement, 1.5cc for big ewes, 1.0cc for gimmers.

Date/time of course records when the lamb arrived.  We use the adjacent blank box to record the date and time we first work the lamb.  That way, we can decide whether there’s enough of a time lag to warrant adjusting the lamb’s birth weight for a later-acquired belly-full of milk. 

Tag.  If you look closely at a lamb’s ears (sheep, not botanical), you know how small they are, too delicate to support a full-sized eartag.  To avoid lamb mixups, we install little plastic temporary eartags on our newborns. 

Notes – our catchall.  Looking over the 2006 cards, it seems we cared most about fleece and whether a lamb was light or dark phase.  Typical are Steve’s comments about Turmeric, roughly translated as ”Brown [fleece], but dark/black at base. Dark eyelids.” 

Twins.  Luckily, Steve designed our card to accommodate the possibility of multiple births.  Last year we needed this option for eight pairs of twins, whew! 

Have I persuaded you of the benefits of lambing cards?  If so, the key is to make them before lambing starts.  Their utility lies in having them ready to grab and go.   You can design them on the computer (Mailmerge on Microsoft Word works just fine), by hand, or on your trusty old Selectric typewriter.  One size does not fit all.  Your custom-designed card will mirror your operation and will include the information important to you. 

Oh yes, if you happen to own a Roger Clemens rookie card you’d like to trade for a tan Soay ewe with great horns, give us a call — collect.
