12
What are mouflon?
Small wild sheep (Ovis musimon) native to
Corsica, Sardinia and Cyprus
Corsico-Sardinian horns curl outward (positive)
Cypriot horns curl inward (perverted)
13
Mouflon have been introduced to mainland France,
Germany, Czech Republic and elsewhere on European
mainland
14
Are mouflon wild or feral?
Distribution of Ovis gmelini

Mouflon were already fully domestic when they
were brought to Cyprus, but only just when they
were brought to Corsica and Sardinia

17
Earliest domestic sheep
  • Ali Kosh, W.Iran 8900

  • bone collagen
  • 9500
  • carbonised bone
  • Nevali Çori, S.E.Turkey 8500-8000
  • Asikli Höyük, S.E.Turkey 8000-7800
  • Tell Abu Hureyra, N.Syria 8000-7800
  • Jericho, Palestine 7500
  • Tepe Guran, W.Iran 7500-7000
  • Shillourokambos, Cyprus 8500-8000
  • Haua Fteah, Libya early 5th mill.

18
Breeds of sheep
  • Hairy breeds
  • Most of Africa, much of S.E.Europe Tibet.
  • Ears pendulous often have throat tags
  • Include
  • Fat-tailed sheep widespread in Africa and
    western Asia
  • Fat-rumped sheep N.E.Africa
  • Wool breeds
  • Wool classed as
  • Coarse gt40µ, Medium 25-40µ, Fine lt25µ
  • Long gt15cm in 1 years growth, medium 5-15, short
    lt5cm

19
Hairy sheep
Kargalin fat-rumped sheep
Cameroon dwarf sheep
20
Fat-tailed sheep
From Rudolf the Elders New History of Ethiopia
(1682)
Baluchi breed
Mehraban breed
21
Wild sheep have both contour hairs (kemps) and
underwool
Kemps are narrowed in hairy Soay, lost altogether
in woolly Soay
Coarse, medium and fine wools have lost fine,
extreme and medium/coarse fibres respectively
22
Ratio of primary to secondary follicles is
important
Primary follicles formed early in foetal life,
produce coarse hairs secondary follicles, formed
around birth, produce much finer hairs.
23
Milking sheep
Only the East Friesian is a specific dairy breed,
but many other breeds are milked.
Qashqai sheep, Iran
24
Robert Bakewell (1725 - 1795)the founder of
modern scientific breeding
Founded the Leicester Longwool breed

Mediterranean and central Europe
Egypt, 2500 B.C.
Sicilian
27
Four-horned sheepManx Loghtan
Fleece is coloured like other primitive
breeds. Pigmentless fleece first appears in a
Scythian burial mound, 400 B.C.
28
North Ronaldsay sheep
Orkney Is. like many specialized longwool
breeds, found in Viking-settled British
islands. On North Ronaldsay, the sheep are
confined to the seashore by a stone wall, so they
are forced to eat seaweed, and blood urea levels
are higher than usually considered compatible
with good health!
29
Finewool sheep Merino
Developed in Spain, as a trail breed, with a
well-developed flocking instinct, from 1200 A.D.
on, using Spanish / E.European finewool cross
originally made by the Romans.
Negretti merino (Austria), 1892

31
The ultimate longwoolKarakul sheep
Persian lamb is the pelt of very young lambs
glossy, dark, very tightly curled.
32
Woolly sheep first appeared after about 2500 B.C.
Mesopotamia, probably Assyrian period
Knossos, geometric period
33
Behaviour of sheep
  • Marked flock cohesion, all graze and move
    together
  • Leadership in flock changes
  • Bleat to maintain contact
  • Flocks forced together dont integrate
  • Vision excellent, but dependant on movement
  • Can scent humans at 500m downwind

34
Feeding
  • Mainly grass, especially forbs (dicots growing
    among grasses), but take a few shrub and tree
    parts
  • Bite their food off, not lick like cow
  • Upper lip cleft, permitting close cropping
  • Move erratically according to grass availability
  • Ewe flocks occupy best ground
  • A grazing sheep travels 8-16km per day (wild or
    domestic)
  • Mouflon and Soay are more sedentary than true
    wild sheep

35
Breeding ewes
  • Breeding season centred about shortest day
  • Triggered by change from decreasing to increasing
    darkness
  • Starts 10-14 weeks later than the change in most
    breeds
  • Breeding season shorter in colder climates
  • 7-13 heats per season
  • First and some later ovulations occur without
    oestrus (still heats)
  • Oestrus lasts 27 hours (range 3-70)
  • Cycle length 16 days (usual range 14-19)
  • Gestation 145-150 days

36
Breeding rams.
  • Rams sperm levels lower, but not eliminated,
    outside breeding season
  • Wild rams fight by rearing up, clashing horn
    bases (detail different in bighorn, argali,
    urial)
  • Dominant ram copulates 20x a day over 2 weeks
  • Dominant ram tends only 15-20 of ewes
  • Castration (wethering) is often incomplete
    (rigs).

37
Birth and development
  • 90 of ewes can be expected to breed each year
  • Twinning rate varies by breed
  • Most breeds one third or less
  • Border Leicester more than half are twins
  • Lamb-ewe bond weak, dissolves altogether at
    weaning (4-5 months in wild sheep)
  • No fixed puberty age
  • Early lambs are older at first heat than late
    lambs

38
Goats (genus Capra)
  • Capra hircus Domestic goat
  • Capra aegagrus Bezoar goat
  • Capra falconeri Markhor
  • Capra cylindricornis Tur
  • 6 species of ibex
  • Capra ibex Alpine ibex
  • Capra pyrenaica Spanish ibex
  • Capra caucasica Caucasian ibex
  • Capra sibirica Siberian ibex
  • Capra nubiana Nubian ibex
  • Capra walie Walia ibex

How to tell the sheep from the goats (contd.)
43
Sheep dont climb trees -
-but goats do. Goats crop the grass less deeply
than sheep, but defoliate the trees.

- And in the centre, they hybridize
48
A few breeds of domestic goats have scimitar
horns, like bezoar -
Bezoar goat, Iran
Swiss Toggenberg goat
49
- but most domestic goats have spiral horns,
unlike the bezoar. Does this mean some of them
are descended from the markhor?
Agrigento goat
Markhor Capra falconeri
50
Two types of spiral
Heteronymous Right horn has a left-hand
spiral (anterior keel travels round front of horn
and goes round lateral side)
Homonymous Right horn has a right-hand
spiral (anterior keel tucks round the back on the
medial side)
Kurdish goat
Agrigento goat
51
Most (but not all) domestic goats are homonymous
markhor is heteronymous.But a few bezoar in the
Caucasus are reported to have homonymous spiral
horns
Agrigento goat
Markhor Capra falconeri

than bezoar

Domestic spiral-horned goats
From Zeuner, 1955
55
Chiltan goats
In the Chiltan Hills, Pakistan, some
spiral-horned (heteronymous) wild goats occur
among the ordinary bezoar. Are they a morph of
bezoar, or hybrids with (formerly sympatric)
markhor?
56
Chiltan goat is not a bezoarBest interpreted as
a hybrid
57
Aegean wild goats
Wild goats, looking very like small bezoar (but
sometimes with slightly spiraled horns) live on
Crete, Erimomilos and Yioura. Are they truly
wild, or feral?
Cretan wild goat
58
The Aegean goats fall between wild and
domestic. They are probably derived from very
early-stage domesticates

Breeds of goats contd.
  • Many goats bred for hair
  • Kurdish breeds, Turkey to Central Asia
  • Angora - finest of Kurdish breeds produces
    mohair
  • Mohair grows 15-30cm/year
  • Usually clipped twice a year
  • Clip has nearly doubled under selective breeding
  • Much smoother surface than wool
  • Central Asian Down breeds, Caspian Sea to Gobi
    and Tibet
  • Cashmere finest of Down breeds produces
    fluffy underwool called Pashm
  • Pasha long, straight silky
  • Only 85 grams in a clip

  • Lop-eared
  • Often hornless
  • Widely milked
  • Dwarf breeds
  • Bred in Africa, Arabia, Tibet, Lapland
  • Meat, milk, skins (for bags)
  • Useful in eating crop stubble
  • Often, especially in Africa, housed only at
    night, roam free by day, return to their correct
    quarters
