18Breeds 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
19Hairy sheep
Kargalin fat-rumped sheep
Cameroon dwarf sheep
20Fat-tailed sheep
From Rudolf the Elders New History of Ethiopia
(1682)
Baluchi breed
Mehraban breed
21Wild 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
22Ratio 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.
23Milking sheep
Only the East Friesian is a specific dairy breed,
but many other breeds are milked.
Qashqai sheep, Iran

modern scientific breeding

27Four-horned sheepManx Loghtan
Fleece is coloured like other primitive
breeds. Pigmentless fleece first appears in a
Scythian burial mound, 400 B.C.
28North 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!
29Finewool 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originally made by the Romans.

31The ultimate longwoolKarakul sheep
Persian lamb is the pelt of very young lambs
glossy, dark, very tightly curled.
32Woolly sheep first appeared after about 2500 B.C.
Mesopotamia, probably Assyrian period
Knossos, geometric period
33Behaviour 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
34Feeding
- 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
35Breeding 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
36Breeding 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).
37Birth 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
38Goats (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

42How to tell the sheep from the goats (contd.)
43Sheep dont climb trees -
-but goats do. Goats crop the grass less deeply
than sheep, but defoliate the trees.

48A 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
50Two 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
51Most (but not all) domestic goats are homonymous
markhor is heteronymous.But a few bezoar in the
Caucasus are reported to have homonymous spiral
horns

55Chiltan 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?
56Chiltan goat is not a bezoarBest interpreted as
a hybrid
57Aegean 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
58The Aegean goats fall between wild and
domestic. They are probably derived from very
early-stage domesticates
