Van Rooy Sheep Prove Their Value for South African Farmers

The Van Rooy sheep breed was developed in South Africa for South African farming conditions. Producers describe it as a reliable option because it delivers high fertility, strong resilience, and consistent meat quality. Pieter Wiese, owner of the Kasteel stud in the Northern Cape, shared his experience with the breed and explained why it remains an economic choice for local farmers.

Wiese serves as chairperson of the Van Rooy Sheep Breeders’ Association of South Africa. He said the breed performs well in harsh conditions and continues to show strong results in semi arid regions such as the Karoo. He highlighted its low cost of production and its ability to maintain output even during difficult seasons.

The breed was developed in the early 1900s. Senator JC van Rooy experimented with Ronderib Afrikaners, Rambouillets and Blackhead Persians to create a hardy sheep that could cope with repeated droughts. The result was a robust animal with strong conformation, reliable production and the ability to handle tough grazing.

Van Rooy sheep are white with woolly hair on the upper body and short hair on the head and legs. They carry fat on the rump, which serves as an energy reserve. This allows them to maintain body condition when feed is limited. The breed has strong resistance to parasites and diseases, which helps reduce veterinary costs.

Wiese farms his flock in the Hardemans Karoo near Loxton. His land includes a mix of bushman grass and African sheepbush. He runs a stocking rate of eight to ten hectares per ewe and uses a five camp grazing system to protect veld health. Each camp rests for at least a year before the flock returns.

He chose the Van Rooy for its low maintenance needs and reliable performance under pressure. He said the breed’s strong herding instinct reduces labour needs and supports easier management. High mothering ability and reliable fertility add to the economic value of the flock.

Van Rooy carcasses show strong results on the hook. The breed crosses well with Dorper, Dormer and Merino sheep. Producers value the breed for its marbling and the speed at which required fat cover develops in crossbreeding. Fat storage in the tail helps maintain fertility and supports production during adverse periods.

Weaning weights at Kasteel range from 30kg to 40kg at three to four months of age. Wiese runs six breeding seasons tied to the uneven months of the year. Rams stay with the ewes for 34 days and rest for 26 days. His ewes mature early and lamb every seven to eight months.

Wiese keeps input costs low. He only considers a production lick in extreme drought. He focuses on producing functional animals that fit the breed standards and perform well in the semi arid conditions of his farm. His stud flock includes about 500 ewes, and he breeds his own rams for his commercial flock.

Predation remains a major challenge. Black backed jackal and caracal cause heavy losses across the Northern Cape. Wiese said the province’s average weaning percentage stands at 36 percent because of predation. Stock theft adds further pressure and affects farmers’ ability to maintain stable production.

The Van Rooy remains a practical option for farmers who want to keep costs down and maintain output in tough conditions. Its ability to thrive on natural grazing, produce quality carcasses and support consistent reproduction makes it a dependable choice for commercial and smallholder producers.
