This study focuses on the utilization of video image analysis (VIA) to evaluate the composition of light lamb carcasses (4.52 \u00b1 1.34 kg, mean cold carcass weight \u00b1 SD). Photographic images capturing the lateral and dorsal sides of fifty-five light lamb carcasses were subjected to analysis. A comprehensive set of measurements was recorded, encompassing dimensions such as lengths, widths, angles, areas, and perimeters, totaling 21 measurements for the lateral view images and 29 for the dorsal view images. K-Folds stepwise multiple regression analyses were employed to construct prediction models for carcass tissue weights (including muscle, subcutaneous fat, intermuscular fat, and bone) and their respective percentages. The most effective prediction equations were established using data from cold carcass weight (CCW) and measurements from both dorsal and lateral views. These models accounted for a substantial portion of the observed variation in the weights of all carcass tissues (with K-fold-R2 ranging from 0.83 to 0.98). In terms of carcass tissue percentages, although the degree of variation explained was slightly lower (with K-fold-R2 ranging from 0.41 to 0.78), the VIA measurements remained integral to the predictive models. These findings underscore the efficacy of VIA as an objective tool for assessing the composition of light lamb carcasses, which are carcasses weighing \u2248 4\u20138 kg.<\/jats:p>","DOI":"10.3390\/ani14111593","type":"journal-article","created":{"date-parts":[[2024,5,28]],"date-time":"2024-05-28T13:32:55Z","timestamp":1716903175000},"page":"1593","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Using Image Analysis Technique for Predicting Light Lamb Carcass Composition"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3907-5117","authenticated-orcid":false,"given":"Jo\u00e3o J.","family":"Afonso","sequence":"first","affiliation":[{"name":"Centre for Interdisciplinary Research in Animal Health (CIISA), Faculty of Veterinary Medicine, University of Lisbon, Avenida da Universidade T\u00e9cnica, 1300-477 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0482-5459","authenticated-orcid":false,"given":"Mariana","family":"Almeida","sequence":"additional","affiliation":[{"name":"Associate Laboratory of Animal and Veterinary Science (AL4AnimalS), Veterinary and Animal Research Centre (CECAV), University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3732-6608","authenticated-orcid":false,"given":"Ana Catharina","family":"Batista","sequence":"additional","affiliation":[{"name":"Associate Laboratory of Animal and Veterinary Science (AL4AnimalS), Veterinary and Animal Research Centre (CECAV), University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8390-4907","authenticated-orcid":false,"given":"Cristina","family":"Guedes","sequence":"additional","affiliation":[{"name":"Associate Laboratory of Animal and Veterinary Science (AL4AnimalS), Veterinary and Animal Research Centre (CECAV), University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4607-4796","authenticated-orcid":false,"given":"Alfredo","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Mountain Research Centre (CIMO), Escola Superior Agr\u00e1ria, Instituto Polit\u00e9cnico de Bragan\u00e7a, Campus Sta Apol\u00f3nia Apt 1172, 5301-855 Bragan\u00e7a, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7045-2075","authenticated-orcid":false,"given":"Severiano","family":"Silva","sequence":"additional","affiliation":[{"name":"Associate Laboratory of Animal and Veterinary Science (AL4AnimalS), Veterinary and Animal Research Centre (CECAV), University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3581-5595","authenticated-orcid":false,"given":"Virg\u00ednia","family":"Santos","sequence":"additional","affiliation":[{"name":"Associate Laboratory of Animal and Veterinary Science (AL4AnimalS), Veterinary and Animal Research Centre (CECAV), University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1250","DOI":"10.1017\/S1751731115000336","article-title":"Non-invasive methods for the determination of body and carcass composition in livestock: Dual energy X-ray absorptiometry, computed tomography, magnetic resonance imaging and ultrasound: Invited review","volume":"9","author":"Scholz","year":"2015","journal-title":"Animal"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"545","DOI":"10.4141\/cjas-2014-038","article-title":"Review: Canadian beef grading\u2014Opportunities to identify carcass and meat quality traits valued by consumers","volume":"94","author":"Aalhus","year":"2014","journal-title":"Can.
