However, conventional methods often involve labor-intensive procedures and lack instant and non-invasive solutions. This study proposed an intelligent weight prediction approach for cows based on semantic segmentation and Back Propagation (BP) neural network. The proposed semantic segmentation method leveraged a hybrid model which combined ResNet-101-D with the Squeeze-and-Excitation (SE) attention mechanism to obtain precise morphological features from cow images. The body size parameters and physical measurements were then used for training the regression-based machine learning models to estimate the weight of individual cattle. The comparative analysis methods revealed that the BP neural network achieved the best results with an MAE of 13.11 pounds and an RMSE of 22.73 pounds. By eliminating the need for physical contact, this approach not only improves animal welfare but also mitigates potential risks. The work addresses the specific needs of welfare farming and aims to promote animal welfare and advance the field of precision agriculture.<\/jats:p>","DOI":"10.3389\/frai.2024.1299169","type":"journal-article","created":{"date-parts":[[2024,1,29]],"date-time":"2024-01-29T04:28:06Z","timestamp":1706502486000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":21,"title":["Intelligent weight prediction of cows based on semantic segmentation and back propagation neural network"],"prefix":"10.3389","volume":"7","author":[{"given":"Beibei","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifan","family":"Mao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wensheng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guipeng","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,1,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"4431","DOI":"10.3168\/jds.2010-4002","article-title":"Automatic recording of daily walkover liveweight of dairy cattle at pasture in the first 100 days in milk","volume":"94","author":"Alawneh","year":"2011","journal-title":"J.
