摘要

本研究旨在评价马里南部4个地区(Dioila、Kolondieba、Yanfolila和Kita)饲养的Djallonke羊的一些形态特征。从这些地区随机选取260只羊(公羊40只,母羊220只),测定其毛色、是否有角/垂角、肩高(HW)和活重(LBW)等性状。动物分为< 1 ~≥4岁5个年龄组,每组均以雌性为主。几乎所有的雄性都有角(94%),而只有一小部分雌性(6%)有角。在所有动物中,白带较少出现(10%),主要的被毛颜色是纯白色(45%)和带特殊颜色的白色(38%)。高重和LBW值在Dioila和Kolondieba公羊之间差异不显著,但高于Kita和Yanfolila公羊。来自Kita、Kolondieba和Yanfolila的母羊的HW和LBW值相当,但这些值低于来自Dioila的母羊。这些发现可以作为设计和实施遗传项目的基础,该项目旨在确保马里Djallonke羊的可持续保护和增值。关键词:贾隆克羊,形态特征,马里

Morphological characteristics of indigenous Djallonk sheep in rural areas in the south of Mali
This study aimed at evaluating some morphological traits in Djallonke sheep reared in four localities (Dioila, Kolondieba, Yanfolila and Kita) in the south of Mali. Two hundred and sixty sheep (40 males and 220 females) randomly selected from these localities were used for measuring the following traits: Coat color, presence of horns/wattles, height at withers (HW), and live body weight (LBW). Animals belonged to five age groups ranging from < 1 year to ≥ 4 years, with females being predominant in each group. Nearly all males had horns (94%), whereas these were present only in a small subset of females (6%). For all animals, wattles were less frequent (10%) and the dominant coat color was plain white (45%) and white with particularities (38%). HW and LBW values were not significantly different between rams from Dioila and Kolondieba but were higher than those of their counterparts from Kita and Yanfolila. Ewes from Kita, Kolondieba, and Yanfolila displayed comparable values for both HW and LBW but these were lower than those of their counterparts from Dioila. These findings might serve as a basis for designing and implementing a genetic project aimed at ensuring the sustainable conservation and valorization of Djallonke sheep in Mali.
