- Description of the main attributes (origin, gender, age, body condition, and slaughter weight) at slaughter house arrival and their impact on carcass characteristics from cull Quarter Horse FJ Gamboa del Real O Carrillo Muro JI Aguilera Soto P Hernández Briano A Rivera Villegas A Barreras Serrano A Plascencia Jorquera A Estrada Angulo JD Urías-Estrada BI Castro Pérez Multidisciplinaria (Ciencias Naturales y Exactas) Equine Quarter horse carcass traits attributes at slaughter In order to describe the effects of origin (Mexico and United States of America), sex, age at slaughter (AS, 4 categories), body condition score (BCS, 5 categories) and slaughter weight (SW, 4 categories) on carcass characteristics of culled quarter horses, data from 235 horses sacrificed in the same slaughter facility within a 150 days period were analyzed. Overall, 74.5% were from the US, 80% were < 15 years of age and had BCS ≤ 4, and sex proportion was similar (51.5% female vs 48.5% males). Horses from USA had heavier SW (27%), leg circumference (4%), carcass weight (4.2%) and carcass yield (2.9%). Sex did not affect any characteristics evaluated. Horses from 3 to 8 years had greater rib eye area (REA) and backfat thickness. Except for leg length, as BCS and SW improved, all carcass characteristics linearly increased as BCS and SW increased. It is concluded that origin, sex, and age, explained very little on the carcass characteristics. The slaughter weight mainly explained changes in linear measures, carcass weight, and compact index, while BCS mainly explained carcass yield and REA. 2022 artículo científico 1665-1456 https://www.redalyc.org/articulo.oa?id=672974941016 https://www.redalyc.org/journal/6729/672974941016/ https://www.redalyc.org/journal/6729/672974941016/html/ https://www.redalyc.org/journal/6729/672974941016/672974941016.epub https://www.redalyc.org/journal/6729/672974941016/movil 10.18633/biotecnia.v24i2.1543 en http://www.redalyc.org/revista.oa?id=6729 Biotecnia application/pdf Universidad de Sonora Biotecnia (México) Num.2 Vol.24
