Coopworth sheep
（重定向自Coopworth）
The Coopworth breed of sheep was developed by a team of scientists at Lincoln College (now Lincoln University) in Canterbury, New Zealand, to increase lambing percentages of Romney ewes when mated with Border Leicester rams. The breed makes up the second largest flock in New Zealand. It is also bred in Australia, parts of Europe, and the United States. The Coopworth is used for both meat and wool. An average fleece weighs 5 kg with a fibre diameter of about 30 to 35 microns being in the coarser range of wools with a staple length of between 125 and 200 mm. The live weight of an adult is about 55 kg.
