Colostrum intake in newborn lambs is vital for three main reasons. Firstly, lambs are born with a limited source of energy (stemming from brown adipose tissue) and colostrum provides an excellent energy and nutrient source.

Secondly, it acts as a laxative that rapidly cleans the lamb of any toxins. And thirdly, it has a hugely important role in providing lambs with a source of immunoglobulins (passive immunity from their dam) which act as a barrier to diseases present on the farm.
