Morphometric Characterization of Donkeys (Equus asinus) in D/Kudu Kano State For Selective Breeding and Genetic Conservation
Donkeys (Equus asinus) is a domestic livestock popular in helping farming activities and providing food for some societies. Population of donkeys were drastically decreasing due to the overexploitation for its hides and industrialization. Little is known regarding the morphometric measurements of this species which provide a useful information for selective breeding and genetic conservation. One hundred and forty-four male donkeys from D/Kudu Kano state where enrolled in this study for morphometric characterisation. Seven morphological parameters were analysed in association with age and coat colour of donkeys observed. Descriptive statistical analysis, analysis of variance (ANOVA) as well as correlation coefficient among parameters were evaluated. Result revealed that donkeys in the studied area were categorised into 7 different coat colour with light grey (30.6%) being the dominant colour. High Frequency distribution of donkeys between the ages of 5-7 years (41%) were recorded. Also, both age and coat colour showed a significant (P <0.01) difference on face length, ear length, chest circumference and body length. Significant and positive correlation (r = 0.43–0.91) is observed in all morphological traits except relationship for tail length which is negatively correlated. In conclusion, the morphological features analysed in this study can be regarded as a preliminary for further studies on the Kano donkey breed.
