Successful breeding of sheep firstly requires a plan of desired breeding outcomes so that the appropriate choice of sire rams can be used. The immediate success of breeding requires ewes that are fertile.
It has been shown that shearing ewes mid-pregnancy can increase lamb birth weight from 0.3 to 0.8 kg as compared to shearing just before lambing, which has no effect on birth weight.
Salmonellosis is a bacterial disease that causes a watery, khaki and putrid smelling diarrhoea, and death. Affected sheep are usually found dead. If found alive they are very dull and are often near water. It is most common in two tooth and older sheep and occurs most often in the summer and autumn.
The most efficient time to put weight back on ewes after the rigours of winter is in late lactation - a time when the metabolism of the ewe is at peak efficiency. Don't wait until after weaning.
Rams must be physically sound to achieve a high conception rate. They must not be thin or lame, they must have firm large testicles and no lesions in the external genital tract, they should be shorn no closer than 8 weeks before mating, and they must have had no illnesses in the 2 months prior to mating.
