Extract

A post-parturient rise in worm egg count was seen in ewes which lambed in the autumn following ovulation induced by hormone treatment. Similarly treated ewes in the same flock which proved to be barren showed only a slight increase in egg count. There were indications that hormone treatment may be associated with egg count rises which differ in intensity and duration from those reported in ewes which ovulate spontaneously.
