ETUDE DE QUELQUES CARACTERISTIQUES MORPHOBIOMETRIQUES DE LA RACE LADOUM DU SENEGAL

The study has been realized in tree (3) regions (Dakar, Thies, and Diourbel) in Senegal in order to characterize the breed of sheep called Ladoum in urban areas. The datas are collected in twenty-nine (29) herds from specific observations, descriptions and measurements and focused on: the coast color distribution, the pendants, the hornes wearing, in males and females and the sexual effets on the variations of the high at the withers (HW) and the thoraxtic perimeter (TP). The collected informations have been treated with Excel and the software R Studio. The Ladoum breed appears with a pallet of eight (8) coasts .However three (3) coats are worn in important way by this breed (more than 10% of presence) .They are white coats with black taints, white uniform, and white with black slab. For the Ladoum breed 98.61% of individual are without pendants .That means that the breed is without or a less presence of pendants.The Ladoum females hold strongly hornes (81.61% of the animals) against 17.39% of aceres females.Males are always horned to 100% and our results show an average of 35.8cm of hornes length .The Ladoum adult males have a high average at the withers (HW)of 104.1 ± 6.17cm and the females 97.1 ± 6.17cm. For the thoraxtic perimeter (TP) variable the average is of 116.1cm for the males and of 105.5cm for the females. The differences observed between the males and the females for the variables (HW) and (TP) are very meaningful (P<0.001) In the Ladoums males and females show very important and meaningful differences and very marked sexual dimorphism.
