It may be due to road accident which is common to sheep and goat raised in an extensive system. Another common cause is what is known as “pregnancy toxaemia” of sheep which refers to the state whereby the sheep is stressed during pregnancy. Lowered level of glucose at this stage will cause pregnancy toxaemia which does result in the death of the pregnant sheep.
To prevent this, pregnant sheep should be given adequate care in terms of feeds and other management procedures. Stressful conditions should be avoided at all cost.
