Analysis of the body structure of Djallonke sheep using a multideterminant approach

Primary morphological characterization of West African dwarf (Djallonk) ewes from Cte dIvoire based on qualitative and quantitative traits

“…In this study the variation of the coefficients of the eight quantitative characters range from 6.6 to 16.7% indicating no important variation in the ewes analysed. However, the values for height at withers, body length and chest girth observed in this present study on the Djallonké ewes were comparable to those reported by Birteeb et al (2014) for West African dwarf ewes (57.06 ± 0.28 cm, 54.87 ± 0.35 and 65.19 ± 0.41 cm) in Ghana; by Dayo et al (2015) for Djallonké sheep (54.6 ± 8.2, 58.5 ± 6.3 and 74.72 ± 8.28 cm) in Togo and by Abegaz (2007) and Melesse et al (2013) for indigenous ewes in Ethiopia (from 57 ± 4 to 64.8 ± 1 cm; from 46.5 ± 3.1 to 68.4 ± 1 cm and from 57.1± 4.3 cm to 65.8 ± 6.3 cm).…”

“…Our observations are corroborated by different works that have been reported from previous studies such as the cattle in Ethiopia (Chebo et al, 2013) and goat breeds in Ghana (Hanga et al, 2012), in Algeria (Dekhili et al, 2013) and in Morocco (Hilal et al, 2013;2016) concluding that the morphological measurements variability observed were due to the influence of the environment. The significant morphologic correlations observed are similar with those reported by Cam et al (2010), Lepaz et al (2011) and Birteeb et al, 2014).…”

“…Nevertheless, selection for positively or negatively associated traits is influenced by the production objectives, selection goals and even the socio-cultural demands or conditions of the farmer. Correlation among body traits equally serves as the basis for employment of further multivariate techniques (Birteeb et al, 2012;Yakubu et al, 2011;Birteeb et al, 2014) like Pincipal Component, Factor and Cluster analysis in quantifying trait variability and characterizing breeds.…”

Principal component analysis of body measurements and body indices and their correlation with body weight in Katjang does of Indonesia

“…All animals were measured using measuring tape (butterfly, China) and measuring stick and taken based on previous studies. 6,18,19,25,31 Eleven body measurements were conducted on each goats such as face length (FL: measured from between the horn site/ poll to the lower lip), face width (FW: measured as the widest point of the head), face height (FH: measured from the poll to the jaw), ear length (EL: the distance from the base to the tip of the ear along the dorsal surface), ear width (EW: maximum distance at the middle of the ear), body length (BL: distance from the point of the shoulder to the pin bone), withers height (WH: vertical distance from ground to the point of withers measured vertically from the ridge between the shoulder bones to the fore hoof), chest width (CW: measured as a distance from left to right upper arm), chest depth (CD: the distance from the backbone at the shoulder to the brisket between the front legs), chest girth (CG: perimeter of the chest just behind the front legs and withers) and cannon bone circumference (CC: the smallest circumference of the cannon bone of foreleg). All body measurements were taken by technicians accredited by association.…”

“…Results of principal component analysis not only impact the management of animals but also help in conservation and selection of multiple traits by breeders. 7 The PCA of body measurements in livestock were also used to explain body conformation in several livestock such as goat, [8][9][10][11][12][13][14][15][16][17][18][19] sheep, 6,12,[20][21][22][23][24][25] cattle, [26][27][28][29][30][31] buffalo, 32 horse, 33 chicken 34 and rabbit. 13,14 Despite, previous study reported that the PCA of body measurements were also used to predict body weight in goat, 8-11 sheep 12 and rabbit.…”
