Methods: Photographs of cattle labelled healthy, foot-and-mouth disease or lumpy skin disease were split into a development set of 1277 from a public Kaggle collection and an external set of 985 from two Zenodo records. Six encoders, three convolutional and three vision transformers (ViT-B\/16), were frozen and read through an identical linear head under a grouped five-fold split with five seeds. Discrimination and calibration were co-primary, and the external set was read once. Results: External balanced accuracy ran from 0.906 to 0.819, both extremes being ViT-B\/16 encoders; after Holm correction, the three leading encoders, two attentional and one convolutional, were indistinguishable. The lowest of the six returned a Brier skill score of \u22120.030. A 4 \u00d7 4 thumbnail reached 0.527 against 0.333 for chance and recovered 0.650 of the foot-and-mouth cases. Conclusions: The pretraining recipe, not the convolutional\u2013attentional distinction, ordered both criteria. Discrimination gave no warning of the loss of probabilistic skill, so a proper scoring rule must be reported beside it. External validation cannot expose a cue present in both collections that travels with the label, and low-information controls must accompany it.<\/jats:p>","DOI":"10.3390\/vetsci13090962","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T13:05:26Z","timestamp":1789391126000},"page":"962","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Classification of Foot-and-Mouth and Lumpy Skin Disease in Cattle Using Frozen Pretrained Encoders: A Comparison of Convolutional and Transformer Architectures"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-8909-3778","authenticated-orcid":false,"given":"Paulo","family":"Valerio","sequence":"first","affiliation":[{"name":"Facultad de Ingenier\u00eda, Universidad Tecnol\u00f3gica del Per\u00fa, Lima 15072, Peru"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1489-9056","authenticated-orcid":false,"given":"Wilfredo","family":"Ticona","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda, Universidad Tecnol\u00f3gica del Per\u00fa, Lima 15072, Peru"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e812","DOI":"10.1016\/S2542-5196(22)00147-4","article-title":"Disease control tools to secure animal and public health in a densely populated world","volume":"6","author":"Charlier","year":"2022","journal-title":"Lancet Planet.
