An outbreak of rickets in Corriedale sheep: Evidence for a genetic aetiology
New Zealand Veterinary Journal, 2007A skeletal disease characterised by lameness, limb deformities and reduced growth rate occurred over two successive years in lambs born on a commercial sheep farm in Marlborough. A genetic aetiology was considered likely following exclusion of other known causes of rickets and because of the progressive nature of the disease, even after affected ...

Heritability of scrotal circumference in Corriedale rams
Small Ruminant Research, 1992Abstract Measurements of scrotal circumference were recorded for 1154 ram Corriedale lambs at ten studs. The best estimate was 0.50±0.11 cm, which concurs with reports on other breeds. Due to this value and the importance of scrotal circumference on reproductive aspects, its employment has been suggested as an additional criterion in sheep selection ...

Reproductive performance of Polwarth and corriedale sheep in Tasmania
Theriogenology, 1981The reproductive performance of 27 Polwarth and 9 Corriedale flocks was studied under commercial conditions in Tasmania. Mean ovulation rate was 149% but the mean number of lambs marked per ewe joined was only 88%. The major sources of wastage contributing to the overall loss were identified as an 18% loss of embryos in twin-ovulating ewes which gave ...

Finding the mutation responsible for inherited rickets in Corriedale sheep
New Zealand Veterinary Journal, 2011Inherited rickets of Corriedale sheep is of simple autosomal recessive inheritance. The gross and histological lesions include segmental thickening of physes, persistence of hypertrophic chondrocytes at sites of endochondral ossification, excessive osteoclastic resorption, microfractures and wide unmineralised osteoid seams lining trabeculae and ...

Small Ruminant Research, 2010
Abstract A 5-year survey was undertaken to compare the productivity of crossbred ewes (East Friesian (EF) sires × Corriedale (C) dams), relative to purebred Corriedale ewes in terms of reproduction rate, wool production and quality and milk production.

Milk quality in Merino and Corriedale ewes
Australian Journal of Agricultural Research, 1966Comparisons have been made of the milk quality of ewes of two strains of Merino, strong-wool (S) and medium-wool Peppin (B), and of two breeds, strong-wool Merino and Corriedale (C). The strains were compared in two ways – for ewes suckling single lambs and for ewes suckling a pair of twins containing one lamb of each strain, and the breeds were ...

Response of anovular Corriedale ewes to teasing in spring
Small Ruminant Research, 1991Two hundred and forty adult Corriedale ewes were randomly allocated to four experimental groups. Early short (ES) and early long (EL) teased ewes were introduced to adult vasectomized Corriedale rams on September 12. Group EL remained in continuous contact with the rams for the following 25 d while group ES was reisolated after 5 d.

Epidemiological observations in a Corriedale flock affected by Brucella ovis.
Veterinary research communications, 1998Brucellosis in sheep, caused by Brucella ovis, is primarily a chronic infectious disease of rams with epididymitis as its most characteristic lesion. Six hundred rams from an infected farm were clinically and serologically examined once a year, over a 3-year period. An increase from 2.1% to 6.3% in the prevalence of animals serologically positive to B.
