supplements (eg, grain) may be required to boost energy in the diet if hay/silage/ baleage is of low quality. Introduce concentrates slowly, building up to the maximum daily amount.
Calves and lambs are castrated the same way, but calves are usually done while standing in a race. Use an ordinary elastrator with the prongs toward the body. The ring is opened and the scrotum pulled through. The testes will not always come through with the scrotum, so ensure they are "in the bag" before you gently let the ring close. Make sure the scrotum is clamped above both testes, but without gathering the teats or any excess skin. As you close the ring, the scrotum becomes firm and it's easy to feel that you have both testes. The elastrator may get caught in wool or hair.
ABOVE RIGHT: Lambs will often retain their detached, dead scrota because the ring catches wool as it is applied and so they don't come off until first shorn. The castration scar is completely healed, but you can just see the orange ring still in place.
