INTRODUCTION
In Senegal. morphological description and Tootcchnical comparison havc bccn uscd since to asscss dijcrsit! in
smail ruminants breeds.
As we knows. in domestic animais. blood groups are under thc control of mari! s‘stems. at least 10 in sl~cclx
and 6 in goats( NGWEN T C. 1979 ).
Most of these systems arc polynorphic ( many allclcs on ont locus ). At thc samç timc somc loti arc coding for
antigenic groups named phenogroups.
The complesitv of blood groups and there protcins polymorphism cari be uscd to characterike intra and mtcr
brced diversity.
The present stud! aimed to analyse blood pal!-morphism in Scncgalesc shccps.
MATERIALS AND METHODS
Animais and environnement
Thrce races Peul. Touabire and Djallonke bave bcen uscd. Therc morphobiometric description has bccn made
( Denis , 1975 : Fall M. 1989 ). Zootechnical performances arc known (Fall A rt II/. 1983 : SOW cl OI. 1937 ).
Peu1 and Touabire sheeps are sahelian races living in the northern part of Scncgalese semi - arid /O~C.
Dejallonke sheeps are from thc southcrn part in subhumid zone whcre trypanosomiasis arc found.
Methods
Blood samples are taken from 100 individuals for each sheep races. 5 ml of blood are taken into tube containing
sodium citrate.
Blood groups wxc determinated b> agglutination and hemolysis. Blood proteins \\\\crc’ tvpcd by cle&-phorcsis
RESULTS AND DISCUSSION
Blood groups systems
Sis ( 6 ) blood systems (A B. C. D. M and R ) bave been round in the threc brceds. These systems sho\\\\
polvmorphism with many allcles ( phenogroups). The polymorphism is more significant in sahelian brceds.
The significant diffcrence from the Djallonke and Pcul or Touabire are on allclcs aB. Ca. Da. Ma. and R.
Betwcen Peu1 and Touabire. difference is only on allelc aB.
Blood proteins
transferrin tvpes
Alleles found in Senegalese sheeps are : TfA TfB. TfG. TfC and TfD.
TfG is not found in D.jallonke sheeps. TfD allelc is more frequent in D.jallonkc than in Peu1 and Touabire.

Haemoglobin tvpes
Peu1 and Djallonke sheeps show only a type B haemoglobinc (tïscd allelc ). but the Touabirc shcep sho\\vs
residual variation in this locus (A frequcncy = 0.0 15).
