We’ve only once lost a heavily pregnant ewe to ‘Twin Lamb Disease’, or Pregnancy Toxaemia
– this is one of the metabolic diseases that can affect ewes during
late pregnancy. It’s caused by inadequate nutrition or stress, so it’s
wise to be as calm around the ewes as possible – even moving to a new
field can trigger a stress reaction. Sheep that are over-fat (BCS
>3.5 are also susceptible. Signs to watch for are: reluctance to
feed, laboured breathing, foamy mouth and nostrils, facial or body
twitching and the smell of ketones on the breath (slightly reminiscent
of nail polish remover – once smelt, never forgotten). The condition is
treatable if caught early enough; as soon as we realised there was a
problem, we gave the ewe a drench of Ketol, calcium (by subcutaneous
injection) and antibiotic injections. An internal examination confirmed
that she was not yet ready to lamb. We repeated the calcium and Ketol at
4-hourly intervals, but sadly the ewe died during the early hours of
the morning. This was an unpleasant introduction to another aspect of stock keeping: what to do when an animal dies. The options are limited: it is illegal to bury livestock on the farm, and there are very few hunt kennels left that have the facilities to deal with fallen stock. Up until a few years ago, the local Animal Health Division would arrange to collect sheep free-of-charge under the National Scrapie Plan, but this has now been phased out. It’s a really good idea to have your local information to hand, for you will one day face this inevitability. |
