The aims of the Wonoka stud are to produce healthy and productive rams of the highest quality that meet our clients needs for:
- Full shedding
- Rapid early growth
- Easy care
- Quiet temperament
The Wonoka Stud is located in the picturesque Kapunda Hills on the north western edge of the Barossa Valley in the lower mid north of South Australia.
Annual rainfall of approximately 400mm (16”) is winter-dominant which enables us to grow cereals, legumes and high quality pastures. Sheep are run on cereals during winter and pasture paddocks in spring. Cereal paddocks that are not destined for harvest are then closed up for summer grazing for the ewe flock to ensure they are back in good body condition ready for a February joining.
Lamb and Weaner Management
Lambs are marked and pedigree recorded at 6 weeks of age and vaccinated with both Glanvac 6:1 and Gudair for prevention of Ovine Johnes Disease (OJD). Although a relatively dry environment where the risk of OJD is low, vaccinating provides our clients with a high degree of assurance.
Lambs are weighed, vaccinated (Glanvac 3:1) and weaned in November on to standing crop or on to dry clover paddocks prior to grazing cereal stubbles over the summer and autumn.
Average weaning weight at 3.5 months of age has been between 36kg and 45 kgs over the last 8 years. This early growth has enabled us to market lambs at a young age providing more feed on which to grow out the rams and replacement ewe lambs.
Ewe lambs are joined at 7 months of age or at a minimum weight of 50 kg and in most years return 80% lambings.
We do not routinely drench our sheep for worms, as the incidence appears to be very low in our environment. Ewes are drenched for nasal bot in summer in years when it is a problem.
We do not measure birth weights as Wiltipoll lambs are small and vigorous at birth and lambing difficulty (dystocia) is seldom experienced. We prefer to leave the ewes alone during lambing.
All sheep at Wonoka are performance recorded via the Lambplan system; lambs are weighed at weaning (100 days), and again at 200 days.
All lambs are fat and muscle scanned from January to March the year after birth and allocated an Australian Sheep Breeding Value by Sheep Genetics, based on their own performance plus the performance of their relatives.
