Application of Morphological Indices in the Assessment of Type and Function in Sheep

Live weight and eight body measurements records taken on 284 sheep comprising 226 West African Dwarf and 58 Yankasa sheep were analysed. The sheep were extensively managed within the south west Nigeria. The aim was to achieve a preliminary assessment of type and function from zoometrical indices pro...

E Indices Indigenous sheep Body measurements Function Live weight and eight body measurements records taken on 284 sheep comprising 226 West African Dwarf and 58 Yankasa sheep were analysed. The sheep were extensively managed within the south west Nigeria. The aim was to achieve a preliminary assessment of type and function from zoometrical indices produced from combinations of different morphometric scores. The indices used were weight, height slope, length index, width slope, depth index, foreleg length balance and cumulative index. The body measurements used were wither height, body length, hip length, hip width, rump height, foreleg length, chest width and heart girth. The body measurements showed that the Yankasa is bigger than the WAD sheep. The measured parts are highly correlated. Tested indices showed that both sheep are typical meat animals. This was shown by the cumulative index, length and balance indices which were 2.80, 1.01 and 0.59 in WAD and 1.18, 0.93 and 0.75 for Yankasa respectively.
