Why use boluses over drenches?

There are significant advantages to using boluses over drenches. Drenches have to be administered every few weeks where as a single bolus can last up to four months. This fact alone can save time, effort and money for the farmer. Drenches can also cause a sudden spike in the minerals being administered which in some cases can be damaging to the animal, boluses use a slow release system which ensures the animal is only being administered the correct daily amount of cobalt, selenium and iodine.

Iodine Deficiency in Sheep:

A severe deficiency of iodine causes a lack of essential thyroid hormone production and the thyroid gland enlarges. The enlarged thyroid gland is called goitre. The swelling occurs in the throat area and can be as large as an orange. Goitre is mainly a disease of lambs and kids, it rarely occurs in calves. Goats have a higher requirement for iodine than other livestock. Supplementing ewes with the trace element iodine can prevent goitre and potentially fatal deficiency complications.

Cobalt Deficiency in Sheep:

Cobalt has an important biological role as a constituent of vitamin B12 which is manufactured by micro-organisms in the first stomach (rumen). Cobalt deficiency (pine) occurs where there are low soil cobalt concentrations which may be further complicated by PGE which causes diarrhoea thereby interfering with the absorption of vitamin B12.

Signs of cobalt deficiency are most commonly observed in weaned lambs at pasture during late summer/autumn, and include lethargy, reduced appetite, poor quality wool with an open fleece, small size and poor body condition despite adequate nutrition. There may be tear staining of the cheeks, and pale mucous membranes (eyes) develop after several months.

Cobalt-deficient sheep may fail to respond well to vaccinations and be more susceptible to clostridial diseases (for example pulpy kidney) and pasteurellosis (pneumonia).In severe cases of cobalt deficiency (referred to as ovine white liver syndrome) lambs present with nervous signs including depression, head pressing, and aimless wandering. Cobalt deficiency is much less common in adults but is reported to cause reduced fertility and poor mothering ability but these signs may be more related to generalised low body condition scores.

Selenium Deficiency in Sheep:

Often referred to as white muscle disease, nutritional muscular dystrophy, and stiff lamb disease. White muscle disease occurs in the UK with recognised risk factors such as feeding home grown cereals and root crops, and incorrectly mineralised rations. Selenium deficiency occurs in soils of certain geographic areas world-wide leading to pasture/crop deficiency. Certain root crops are known to be low in both selenium and vitamin E. Feeding grain treated with propionic acid may increase the risk of white muscle disease.
