Internal parasites:
When an animal is affected with internal parasites the sheep becomes under nourished, and this complicates matters, because it is then that they become more vulnerable to other parasites. Death from parasites occurs, for the most part, in lambs, yearlings and very old sheep or those that are not fed adequately. Internal parasites reduce productivity, they cause anemia, wool to break and progressive weakness which can lead to death.
Worms are the worst offenders, they are the predominant internal parasite in sheep and in the west there are eleven species that cause a shepherd problems. These worms live not only in the true stomach, but also the small and large intestines, heart and lungs.
The most common worm in the west is the roundworm that inhabits the digestive system. In parts of the world with high rainfall, a large stomach worm is problematic for sheep named Haemonchus contortus. In parts of the world with a drier climate, a brown stomach worm called Ostertagia circumfecta causes problems. Roundworms feed on blood and bodily fluids found in the stomach lining, this causes the animal anemia and blood loss. If an animal has a heavy infestation, blood loss can quickly become a serious problem.
Lambs are far less tolerant to worm infestation. The amount of worms a mature sheep can cope with can kill a lamb quite quickly, but you may not notice it is in trouble because it does not look thin. One of the effective ways to protect your lambs for infestation when they are out in the pasture is to feed them in what is called "forward creep-grazing", this means that the lambs are grazed in clean pastures before the ewes are put in it and an additional facility of a creep feeder, which is a construction only large enough to let a lamb get in – mum stays outside – it is there that lambs can be fed in a trough with additional clean food.
Identification of worm infestations:
Signs to look for, treatment is covered in a later chapter:
Anemia is usually the first sign that a sheep has been infected by roundworm, though it is not always easily detectable. When an animal becomes anemic it shows up as a very pale, grayish color in the inner, lower eyelids and gums that should normally be a fairly bright pink. The sheep becomes listless, has pale mucous membranes and the condition of its body deteriorates. It is important to get the animal dewormed otherwise it might die.
Scours is diarrhea, and is brought about by the attack of small brownish stomach worms. Immediate treatment is a necessity.
Potbelly when an animal that looks thin develops a great big fat belly, it has a problem called potbelly. Potbelly can be caused by liver flukes.
Wool break if a sheep's wool begins falling out at the roots or breaking off just above the roots, then it has "wool break". However, there are
