Before mating occurs
Make sure ewes are not too fat one month before mating, so that a growing condition can be effected before mating.
Generally, the following practices have a direct or indirect impact on improved reproduction four to six weeks before mating:
Supplement zinc and manganese if a shortfall is present, it raises fertility,
Inoculate against enzootic abortion and pulpy kidney,
Dose for roundworm and noseworm,
Ensure that ewes are in a good condition and have no hoof problems,
Reject all ewes with problem udders, teats that are either abnormally enlarged and multiple teats.
Inject, or dose with, Vitamins A, D and E three weeks before the mating season. This is extremely important, especially during dry periods.
Administer stimulating feed in the form of spare camps, a good lick or a small amount of maize daily.
Put teaser rams in place 2-3 weeks before mating time.
Have rams tested for fertility.
