Breed Information — Île de France

Physical Description

A Large, Polled
Meat Breed

The Île de France is a large, smooth-bodied, polled mutton sheep — meaning it naturally carries no horns. The breed is known for its well-defined muscling, correct conformation, and a compact, deep body frame that signals outstanding meat-producing potential at a glance.

The fleece is strong, white, and entirely free of coloured fibres or kemp, making it commercially valuable both as a meat and wool breed. The breed carries a well-woolled body with a clean face and legs that are free of wool below the knee and hock.

Selected for over 200 years, every physical feature of the Île de France exists for a purpose: wide loins, well-rounded hindquarters, a broad back and deep ribs all translate directly into the premium carcass quality that defines Donkerberg Boerdery lamb.

Reproductive Performance

Built for Productive Flocks

One of the Île de France's greatest commercial strengths is its outstanding reproductive efficiency. With lambing percentages consistently between 150–170%, multiple births are the norm rather than the exception — directly translating into more lambs per ewe per year.

Ewes are early maturing, reaching productive weight at approximately 55 kg, and can achieve up to 1.3 pregnancies per year. They remain productive until 9–10 years of age, making them a long-term investment in flock profitability.

Strong maternal instincts and good milk production ensure that lambs receive excellent early nutrition, supporting the impressive 42-day weaning weights of 19–24 kg that the breed is known for. Rams begin active service from 10 months old.
