It is sometimes said that sheep will take it turns to read the medical dictionary and find ways to die. I don't subscribe to this, I am a firm believer in good management significantly reducing the likeilihood of sheep sucumbing to many opportunistic infections. Sheep are very susceptible to stress and this can be stress from poor housing, over crowding, insufficient or unsuitable grazing or low body condition due to parasitic burden. By ensuring good management you can make life a lot easier on your sheep and in doing so on you.
That said sheep like all animals do get sick from time to time and it can be hard to spot a sheep that isn't doing well, they will do everything they can to maintain an outwardly normal appearance and it may only be at the last moment when they are really very ill before they start to show any obvious signs.
For the sheep owner this means two things good management is essential to the health and well being of your flock and secondly be vigilent. Know your sheep, their behaviour and above all whats normal for them. If you find a sheep separating itself from the flock and this isn't usual behaviour then it can never hurt to take a closer look and see if there is something amiss.
It is rare for me to have a sheep unwell without any obvious reason to explain the problem but I have been watching Aine for a couple of weeks, sometimes she has appeared well and at other times subdued, distanced from the others and not grazing as she would normally do. Having brought her in once for a couple of days and found nothing obviously untoward she went back out only to show signs a few days later that all was not well. Mainly just that she was quieter and resting more than the others. This time when I caught her up it was clear she was scouring
Having an area where you can bring a sheep in and isolate them is essential, you can monitor their progress and ensure that they are kept out of inclement weather, the heat lamp may not be an essential item but if the area is large and the sheep have a choice of where they position themselves, it is surprising how many choose to remain under the lamp ( it may not be essential but it is appreciated.)
If needed I could section off the area to provide several pens, potentially more useful during lambing but this old chicken house has served very well for a variety of uses.
It is never wise to try to diagnose an animal yourself, however there are some basic's of sheep care that should be part of a first aid kit and can save an expensive vet call out particularly as these things seem to happen when it is least convenient. Firstly a good range of wormers, it is generally one of the first questions your vet will ask you. If you are not worming your sheep or can't remember when you last did it, your management needs improving. My most important tool apart from taking a good careful look over a sheep is a thermometer, digital these days is easy and knowing how to correctly take a temperature reading makes all the difference, if you're not sure ask your vet to show you one time. Don't forget to label the thermometer to make sure it just gets used for sheep!
A 60ml lamb feeder is a useful item for drenching and unlike a 60 ml syringe has a nice nozzle which can be used to make sure your sheep gets the drench and not have it spat out everywhere. It is a good idea if your vet is willing to provide them to have on hand some treatments to help with diarrhoea, oral rehydration products and also in cases where needed a product to help improve gastric function. Having these few items on hand may save an expensive vet call out but it doesn't mean you don't need to call the vet, a quick phone call once you have brought a sheep in and examined them and preferably taken their temperature may be all it needs for the vet to provide some useful advice and basic care often with the proviso that if things don't improve to call them back.
Aine seems to have turned a corner although her appetite is still poor and I have discussed her condition with my vet. It may be a while yet before she is fully recovered and with low body condtition she may still have further problems to come with the rest of winter yet to go, she may well need extra attention when she does eventually go back out to the field to make sure she has sufficient reserves to cope with winters demands.
