Extract

Observations of the effect of the immunogen ovandrotone-albumin (Fecundin ® Coopers Animal Health) when used in ewes mated in their breeding season have shown that with a boost-tupping interval (BT) of 21 days for natural oestrus and 28 days for synchronised oestrus there was an increased fecundity but that treated ewes lambed a little later than controls.

While this latter effect was not dramatic it was felt advisable to investigate the use of Fecundin as a means of boosting lamb production in an early lambing flock in conjunction with progestagen and PMSG treatments.
