What is the difference
between the Blackhead and White Dorpers?
The coloration is a
preference as all other traits are basically equal. A White Dorper
ram is used when a breeder does not want spotted lambs produced from
a cross-breeding program with solid white ewes.
Are all Dorpers
polled?
Most Dorpers are
without horns but many rams have scurs, and some will have horns
and this should not disqualify a Dorper
ram from being stud. Experience has shown that horned rams tend to
be more masculine and have a stronger libido.
How much does a Dorper
Weigh?
Mature rams
typically weigh over 250 lbs., ewes, 220 lbs. However, one should
not be obsessed with mature weights. Feed efficiency
is more important than mature weight and
fast growing lambs are traits where the Dorper excels.
What is the productive
life of a Dorper?
Under good
management, a Dorper ewe should produce lambs for 7 years
or more.
Do they have a lot of
twins and triplets?
This depends more on
available nutrition. In South Africa, under good range conditions,
a 150 percent lamb crop is typical and rates more like 180 percent
with improved nutrition.
Can you breed Dorper
ewes any time of year?
Yes. Again,
available nutrition has a major role in conception rates. Lambing
intervals of 8 months, three lamb crops every two years, is a
common practice.
At what age can you
start breeding ewe lambs?
As early as 6-8
months but better conception rates will be achieved at 9-12 months
and the later bred ewes will grow out better.
How many ewes can a
Dorper ram cover?
Ram lambs can
frequently cover 20-25 ewes in a 51-day exposure. Yearling rams
can usually cover 50 ewes.
Do Dorpers have to be
sheared?
No. A Dorper will
shed its covering each summer. Dorpers will shed more completely
as they mature.
Are Dorpers parasite
resistant?
Yes, but not
parasite proof. Many other factors determine parasite problems but
with proper management techniques, dewormings can be held to 2-3
times per year even in higher rainfall areas.
How is the taste of
Dorper meat?
Superb! Dorper lamb
does not have the “lamb taste” that causes so many Americans to
avoid eating lamb. It is succulent and fine textured.
The purpose of the Dorper breed is to produce prime lamb.
What about crossing a
Dorper ram with wool-type ewes?
Early university
trials have shown that the Dorper influence will improve the meat
qualities and growth rate of lambs from popular commercial ewe
breeds. However, the F1 lambs will have a diminished wool
conformation.
What about crossing
Dorper Rams with hair-type ewes?
The Dorper has been
very effective in increasing the growth rate, carcass size and
quality of all the typical hair-type breeds such a the Barbados,
Katahdin, St. Croix, the Mexican Pelibuey and other breeds that
are considered exotic types. Typically, the 75 percent Dorper
crosses will exhibit the Dorper coloration and confirmation.
Can percentage Dorpers
be registered?
Yes. The Dorper
registry regulations allow for a "breeding-up" program.
Ewes can be considered purebred at 7/8s
( 87%) and rams at 15/16s ( 93%)
Dorper.
