Extract

In recent years there has been increasing use of mineral blocks in the diets of sheep both at mating time and in pregnancy. However, recent work carried out at this institute (Joyce, 2000) found that lambs whose dams had access to mineral blocks had significantly lower IgG serum values at 24 hours than lambs whose dams had no access to mineral blocks. This experiment investigated further the effects of supplementing the pregnant ewe diet with mineral blocks on IgG absorption efficiency and on the level of faecal adhesion to the tail-end of the lambs in early life.
