The White
Dorper
A Dorper is a fast growing meat producing sheep. The Dorper is
an easy care animals that produces a fleece of little wool that
is shed late spring to summer. It was developed in South Africa
and is now the second most popular breed in that country.
The breed is well adapted to survive in the arid extensive regions
of South Africa. It has high fertility and maternal instinct,
combined with high growth rates and hardiness. The breed has
the characteristic black head (Dorper) as well as white heads
(White Dorper).
History
of the Dorper
The breed was developed in South Africa in the 1930's by crossing
Blackhead Persian ewes with a Dorset Horn ram. They were bred
to produce a high quality carcass under extensive conditions.
The Blackhead Persian was selected for its non-selective grazing,
coat shedding, hardiness and good mothering abilities. The Dorset
Horn was selected for its rapid growth rates and carcass attributes.
The Breeding program resulted in the development of the black
headed and white headed Dorper. Successive Dorper breeding has
shown it to be a fixed breed type, giving a reliable reproduction
of features and characteristics. It is now numerically the second
to largest sheep breed in South Africa.
The breed was introduced into Australia in 1996 and has the potential
to be developed for domestic and export meat markets.
Conformation
The animal is characteristically barrel shaped with short, dullish
black or white hair on the head. A short, loose light covering
of hair and wool (wool predominating on the forequarter) with
a natural clean kemp underline, is a typical breed standard.
An even distribution of a thin layer of fat compliments the breed.
The Dorper sheds its fleece avoiding the need for mustering for
shearing, crutching and fly control. There is little difference
between blackheaded and whiteheaded Dorpers - the choice is a
matter of target market preference.
The
Standard of Excellence
Conformation:
Head
Strong and long, with large eyes, widely spaced and protectively
placed. Strong nose, strong well-shaped mouth with well-fitted
deep jaws. The forehead must not be dished. The size of the ears
must be in relation to the head. A developed horn base or small
horns are the ideal. Heavy horns are undesirable but permissible.
The head must be covered with short, dullish black hair in the
Dorper and dull, white hair in the White Dorper. The head must
be dry i.e. without indications of fat localization.
" Fore-quarter and neck:
The neck should be of medium length, well-fleshed and broad and
well-coupled to the forequarters. Shoulders should be firm, broad
and strong. A moderate protrusion of the brisket beyond the shoulders,
moderate width and good depth are the ideal. Forelegs must be
strong, straight and well-placed with strong pasterns and hoofs
not too widely split. Weak pasterns and X legs must be discriminated
against according to degree. Shoulders which appear loose, a
brisket which slants up too sharply with no projection beyond
the shoulders, crooked legs and weak walking ability, are faulty.
Barrel
The ideal is a long, deep wide body, ribs well sprung, loin broad
and full. The sheep must have a long straight back and not a
"devil's grip". A slight dip behind the shoulders is
permissible.
Hind-quarter
A long and wide rump is the ideal. The inner and outer twist
to be well fleshed and deep in adult animals. The hind legs must
be strong and well-placed, with sturdy feet and strong pasterns.
Faulty pasterns must be discriminated against according to degree.
The hocks must be strong without a tendency to turn in or out.
Sickle, bandy or perpendicular hocks are culling faults.
Udder and sex organs
A well-developed udder and sex organs are essential in the ewe.
The scrotum of the ram should not be too long and the testicles
should be of equal size and not too small. A split scrotum is
undesirable.
General
appearance
The sheep should be symmetrical and well-proportioned. A calm
temperament with a vigorous appearance is the ideal.
Good
mothering qualities
The Dorper ewe is a very
good mother and protective of her young. Multiple births are
common, with some instances of triplets recorded. Lambs are extremely
mobile at birth and survival rates are high. The Dorper ewe produces
a large quantity of milk, aiding lamb survival and early growth.
Good
grazing habits
They are non-selective
grazers. Experience so far suggests that Dorpers can adapt to
most grazing conditions. There is evidence that they prefer fibre
to grains and they respond well to good quality hay.
Purebred lambs will start to graze in the first few days after
birth. F1 lambs after about two weeks.
The Dorper can be advantageously incorporated into under-utilized
pastures of lesser quality, thus converting a poor asset into
profit.
Fast
growing
Dorper lambs have an inherent
growth potential (ability to graze at an early age) They grow
rapidly and can attain a high weaning weight.
Dorpers respond well to increased planes of nutrition, giving
growers the potential to increase weights rapidly in response
to market demands.
Weight Gain-
The Dorper lamb grows rapidly and attains a high weaning weight
which again is an economically important characteristic in the
breeding of mutton sheep. A live weight of about 36 kg can be
reached by the Dorper lamb at the age of 3- 4 months. This ensures
a high quality carcass of approximately 16 kg.
Continuous
breeding season
The Dorper is poly-oestrus
(can breed continually, with no defined season). Their breeding
intervals can be as short as 8 months or 3 times in 2 years.
Running rams with ewes continuously is one option that may stimulate
re-production, however it is also likely that ewes will adjust
their fertility according to condition.
CONCLUSION
The Dorpers eat anything. As they were initially bred for arid
regions, they will eat anything and put on weight. As a strong
and non-selective grazer, the Dorper can be advantageously incorporated
into under utilized pastures of lesser quality, thus converting
a non performing asset into one that is profitable. Dorpers are
hardy in every way.
We have selected the White Dorpers in preference to the Dorper
(black headed) purely for the way the White Doper lambs present
in the sale yards. A White Dorper ram crossed with any white
ewe will produce an excellent quality white lamb for sale.
