This long established breed originated in the Friesland/Ost Friesland area in the north of Holland and Germany. In Europe it has been used either pure as a milking breed, as a crossing breed with other milking sheep breeds, or to improve fecundity and milk production in meat production breeds.

In December 1992 eleven pregnant ewes and four rams were imported into New Zealand from Sweden and entered a private quarantine station at Silverstream, near Dunedin. Thereafter a breeding programme was commenced using embryo transfer techniques, with only those animals derived from the embryo transfers eligible for release from quarantine.

The first release occurred in March 1996, with 40 rams being sold while the remaining animals were held back to expand the flock numbers. However, there were substantial sales of semen, with an estimated 50,000 ewes of various breeds being artificially inseminated.

In 1995, the first flock was registered with the NZSBA by Silverstream East Friesians and in 1996 several more flocks were registered and this has continued.

Profile Of the East Friesian Sheep

  • Pink nose, and head and legs clear of wool, pale hooves
  • Lean on the outside of their carcase
  • High fertility; very milky
  • White wool of approximately 37 microns.


A dual purpose, high fertility breed used to increase flock fertility. A sire for creating crossbred ewes and as a terminal crossing sire. Also used for breeding milking ewes.

Breed Classification

East Friesian Ewe © Graham Meadows Photography

A thin-tailed breed that has high fecundity and high milk production.

Particularly used for cross-breeding to improve the milk production and lambing percentage of other sheep breeds. The East Friesian will also become the basis for establishment of a sheep milking industry for the production of fetta cheese and other sheep-milk products.

Bodyweight Milk

Ewes: 75-95 kg (165-209 lb)

Rams: 100-125 kg (220-275 lb)

The most productive sheep breed in the world, producing 500-600 litres per 210 to 230 day lactation.

Meat Wool

Very good lamb growth rates.
Carcase very lean.

Bulky, medium-coarse, white.

Fibre diameter: 35-37 microns.

Staple length: 120-160 mm (4.7-6.3 inches)

Fleece weight: Range 4-5 kg (8.8-11 lb); Average 4.5 kg (10 lb)

Breeding/Lambing

Average of 280 percent in mature ewes.

东弗里生羊(east eastfrierian sheep)源于生长于欧洲北海群岛及沿海岸的沼泽绵羊。有趣的是,荷兰的弗里生省既是包括荷斯坦奶牛在内的弗里生(黑白花)奶牛的发源地,也是弗里生奶绵羊的发源地之一。东弗里生羊原产于德国东北部,是目前世界绵羊品种中产奶性能最好的品种,成年母羊260~300天产奶量500~810kg,乳脂率6%~6.5%。波兰的东弗里生羊日产奶3.75 kg,最高记录达到一个泌乳期产奶1498 kg。
聽 聽 该品种体格大,体型结构良好。公、母羊均无角,被毛白色,偶有纯黑色个体出现。体躯宽长,腰部结实,肋骨拱圆,臀部略有倾斜,尾瘦长无毛。乳房结构优良、宽广,乳头良好。活重成年公羊90~120kg,成年母羊70~90kg。剪毛量成年公羊5~6kg,成年母羊4.5 kg。羊毛长度10-15cm。羊毛同质,羊毛细度46~56支,净毛率60%~70%。母羔在4月龄达初情期,发情季节持续时间约为5个月,平均正常发情8.8次。欧洲北部的东弗里生羊与芬兰兰德瑞斯羊和俄罗斯罗曼诺夫羊都属于高繁殖率品种,东弗里生羊的产羔率为200%~230%。
聽 聽 东弗里生羊是经过几个世纪的良好饲养管理和认真的遗传改良培育出的高产奶量品种,该品种性情温顺,适于固定式挤奶系统。这一品种用来同其他品种进行杂交来提高产奶量和繁殖力。在有的国家被用于培育合成母系和新的乳用品种。我国也引入有该品种。
