Data were recorded under field conditions with equal coverage of the five breeds, viz., Karnah, Gurez, Poonchi, Bakerwal and Changthangi on body length (BL), height at withers (HW), chest girth (CG), ear length (EL), and tail length (TL). Furthermore, four derived traits (indices) were studied, which included an index of body frame (IBF), an index of thorax development (ITD), a Baron\u2013Crevat index (BCI), and an index of body weight (IBW). Multivariate principal component analysis (PCA) was undertaken on nine morphometric traits. Kaiser\u2019s criterion was used to reduce the number of principal components for further analysis and interpretation. The adequacy of sampling was evaluated using Kaiser\u2013Meyer\u2013Olkin (KMO) test and Bartlett\u2019s test of sphericity. The mean BL ranged from 52.15 (Changthangi) to 71.13 (Gurez). The estimates of HW, CG, EL and TL were highest in Gurez (63.49), Bakerwal (84.82), Bakerwal (7.26), and Karnah (8.18) breeds, respectively. Among the derived traits, the highest IBF was observed in the Gurez breed with an estimate of 112.22. Upon multivariate PCA on the dataset, the first four principal components were able to explain 92.117% of the total variance. The KMO test, Bartlett\u2019s test of sphericity and estimated communalities showed the appropriateness of PCA on the evaluated traits. Four eigenvalues were greater than one and were extracted for further analysis. Morphometric traits were highly correlated, except for EL and TL that showed lower correlation estimates with other traits. The Changthangi population showed the lowest estimates of BL, HW, CG and rectangular body frame. The present study ascertained important morphometric traits\/indices that can help in developing selection criteria and formulating sustainable breeding and conservation plans vis-\u00e0-vis the unique sheep breeds of the temperate Himalayas.<\/jats:p>","DOI":"10.1017\/s0967199422000636","type":"journal-article","created":{"date-parts":[[2023,1,9]],"date-time":"2023-01-09T08:22:26Z","timestamp":1673252546000},"page":"157-162","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":5,"title":["Morphometric indices of native sheep breeds of the Himalayan region of India using multivariate principal component analysis"],"prefix":"10.1017","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2213-3114","authenticated-orcid":false,"given":"Nusrat Nabi","family":"Khan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nazir A.","family":"Ganai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tavsief","family":"Ahmad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed","family":"Shanaz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruksana","family":"Majid","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8556-4689","authenticated-orcid":false,"given":"Mohsin Ayoub","family":"Mir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiekh Firdous","family":"Ahmad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2023,1,9]]},"reference":[{"key":"S0967199422000636_ref8","volume-title":"A Textbook on Bakerwal Sheep: Migratory Breed of Jammu and Kashmir","author":"Khan","year":"2021"},{"key":"S0967199422000636_ref4","doi-asserted-by":"publisher","DOI":"10.1007\/BF02291575"},{"key":"S0967199422000636_ref9","first-page":"1251","article-title":"Principal component analysis of morphological traits of Assam hill goat in eastern Himalayan India","volume":"25","author":"Khargharia","year":"2015","journal-title":"Journal of Animal and Plant Sciences"},{"key":"S0967199422000636_ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.smallrumres.2012.09.008"},{"key":"S0967199422000636_ref13","volume-title":"Multivariate statistical methods: A primer","author":"Manly","year":"1994"},{"key":"S0967199422000636_ref11","doi-asserted-by":"publisher","DOI":"10.1017\/S1014233900000523"},{"key":"S0967199422000636_ref14","volume-title":"Multivariate statistical methods","author":"Morrison","year":"1976"},{"key":"S0967199422000636_ref19","doi-asserted-by":"publisher","DOI":"10.1007\/s11250-020-02268-9"},{"key":"S0967199422000636_ref5","first-page":"163","article-title":"Principal component and clustering analysis of functional traits in Swiss dairy cattle","volume":"32","author":"Karacaoren","year":"2008","journal-title":"Turkish Journal of Veterinary and Animal Sciences"},{"key":"S0967199422000636_ref20","doi-asserted-by":"crossref","first-page":"568","DOI":"10.56093\/ijans.v86i5.58497","article-title":"Principal component analysis of body measurements based morphological structure of Madgyal sheep","volume":"86","author":"Yadav","year":"2016","journal-title":"Indian Journal of Animal Sciences"},{"key":"S0967199422000636_ref2","doi-asserted-by":"publisher","DOI":"10.1017\/S2078633611000063"},{"key":"S0967199422000636_ref6","volume-title":"A Textbook on Karnah Sheep: Native Breed of Kashmir (Karnah Valley)","author":"Khan","year":"2021"},{"key":"S0967199422000636_ref15","unstructured":"National Bureau of Animal Genetic Resources.
