Because there is an increasing demand from breeders to register in our studbook. We are re-opening until December2022 our International Studbook for Djallonké Sheep (also known as West African Dwarf Sheep or Cameroon Sheep) for Europeans & North Americans. After this date the studbook will be closed, meaning that only sheep whose parents are registered can be registered themselves. Enthusiasts and breeders of this breed from Spain, France, Italy, the Netherlands, Germany, Belgium... can apply from January 2020 for inclusion in the studbook. Test dates and location (BE or NL) will be provided on time. Several times a year we also cross the pond to visit the States.

Membership fee is $25USD annually.
One-time registration of a stable name is 10 EURO.
Entry to the studbook is 5 EURO per head. 
All first generation inclusion in the studbook requires a DNA profiling at a price of 50 EURO.

The breeder will gain access to an online database where pedigrees can be viewed, adjusted, and test breedings done. From 5 generations a pedigree certificate will be issued for the breeder.

Registration classes 
  • AAA (Correct type) : DNA profiled + both parents DNA profiled
  • AA (Correct type): DNA profiled, 1 parent not DNA profiled or registered
  • A (Correct type): DNA profiled + both parents not DNA profiled or registered
  • A- (Correct type): Not DNA profiled, 1 or both parents not DNA profiled or registered, or Not DNA profiled, both parents DNA profiled
  • BBB (Minor error): DNA profiled + both parents DNA profiled. (Rams with short horns or polled)

  • B (Minor error): DNA profiled + both parents not DNA profiled. (Rams with short horns or polled)
  • B- (Minor error): Not DNA profiled, 1 or both parents not DNA profiled or registered, or Not DNA profiled, both parents DNA profiled. (Rams with short horns or polled)
  • C (Questionable): Suspicious Barbados crossing - oversized + (Rams polled)

Upgrade rules for the promotion of horned rams and the use of DNA profiling.

An AAA (horned) ram can breed a B- ewe. The offspring can than become AA, A-, BB or B-. 

An AAA ewe can be bred by a B- (short horned or polled) ram. The offspring ewes can than become AAA, AA, A or A-. The offspring (polled) rams can than become BB or B-. The offspring (horned) rams can than become AA or A-.

All sheep must be provided with an ear tag before the inspection & DNA test and studbook registration.

New Blood
Together with European zoos we will work on the introduction of new blood. We are currently working on the quarontine of rams and will be conducting genetic tests before proceeding to sperm collection and embryo development. There are plans to bring 10 rams from Guinea-Togo-Nigeria-Cameroon-Chad to Europe in 2020-2022 by embryo transfer. 

 In Europe we are going to collaborate with VHL Genetics from the Netherlands for DNA profiling.


Descendancy check
Every year the Djallonké working group requires a percentage of the registered lambs to be checked for descent (= DNA comparison of the blood samples of the relevant lamb and the respective father and mother). The analysis of the samples is carried out by an external laboratory. Breeders are thus randomly designated. The working group carries out the checks. They will contact the breeder to agree on a date on which the check can take place. The lamb to be checked will be selected by the sampler at the time of visit. The blood is taken via a blood test. It is important to know that in accordance with the rules of procedure: Refusing a DNA check can result in all lambs born at this breeder of the current birth season being deleted from the studbook. If the pedigree (comparative test between lamb-father-mother; lamb-father; lamb-mother) is incorrect, a counter-expertise can be performed (at the expense of the breeder) or the lamb concerned (and the corresponding full brothers / sisters) from the studbook. In addition, the AOBA Board of Directors can in that case decide to also test other descendants at the company. The working group can carry out a comparative test between lamb-mother or lamb-father at its own expense. It is therefore of the utmost importance that the pedigree check proceeds as correctly as possible !!!
