The Suffolk originated in the area surrounding Bury St. Edmunds in Suffolk in the late eighteenth century, as a result of cross-breeding when Norfolk Horn ewes were put to improved Southdown rams. [4]: 923 They were at first known as Blackfaces or Southdown-Norfolks; [5] the first use of the name "Suffolk" for these sheep dates to 1797. In 1810 ...
In addition to lambs and other attendant sheep, the station has a base flock of 3,000 mature sheep. [2] Breeds developed at the U.S. Sheep Experiment Station include: The Columbia, a dual-purpose breed and one of the first originating in the U.S. Early crosses were made in Wyoming, but the originating flock was moved to the USSES in 1918.
The disease was confirmed as present in the UK on 22 January 2012, on being formally identified in four sheep farms in Norfolk, Suffolk and East Sussex. [5] By 27 February 2012, the disease was reported in other counties in the south of England including the Isle of Wight, Wiltshire, West Berkshire, Gloucestershire, Hampshire and Cornwall. [22]

[ 8 ] The mutation which causes spider lamb syndrome is found on ovine chromosome 6, [ 9 ] and involves the inactivation of fibroblast growth factor receptor 3 . [ 10 ]
The Southdown was traditionally reared for meat and wool. During the day the sheep pastured freely on the downs, and at night they were close-folded in the arable fields of the farmers, where they helped to increase soil fertility. [10] Fleece weights (greasy) are about 2–3.5 kg for ewes, 3.5–5.5 kg for rams.

Sheep are flock animals and strongly gregarious; much sheep behavior can be understood on the basis of these tendencies. The dominance hierarchy of sheep and their natural inclination to follow a leader to new pastures were the pivotal factors in sheep being one of the first domesticated livestock species. [ 58 ]
The White Suffolk was bred by Ewan Roberts, of the University of New South Wales, from 1977.His intention was to create a sheep that had the large size, high ewe fecundity and rapid growth rate of the original British Suffolk, but without the black face and legs and without the occasional dark fibres in the wool which greatly reduced its value in the Australian market.
