This research was conducted to study the effect of breed, Jaca Navarra (JN) vs. Burguete (BU), and finishing diet, conventional concentrate-diet 1 vs. silage and organic feed diet 2-on growth parameters and carcass characteristics from forty-six foals. Parameters as live weight (LW), average daily gain (ADG), body condition score (BCS), and fat depots were monitoring. In addition, the carcass parameters assessed were: carcass weight (CW), conformation, degree of fatness, morphology, and pH. Moreover, hindquarters of the left-half carcasses were sectioned in the main commercial primal cuts of leg. Results showed a clear "breed effect" in favor of BU foals, recording the highest productive values and carcass traits compared with JN foals. On the other hand, finishing diet contributed to improving the productive and carcass features of JN foals. In particular, diet 1 showed to affect positively the features analyzed compared with diet 2. Nevertheless, the meat primal cuts resulted in being unaffected by the breed and diet effects (except for knuckle), obtaining similar values among the groups of animals.
本研究旨在探讨品种（哈卡纳瓦拉马[JN]与布尔盖特马[BU]）以及育肥日粮（传统精料日粮1与青贮料和有机饲料日粮2）对46匹驹马生长参数和胴体特征的影响。监测了活重（LW）、平均日增重（ADG）、体况评分（BCS）和脂肪沉积等参数。此外，评估的胴体参数包括：胴体重（CW）、体型、肥度、形态和pH值。而且，将左半侧胴体的后躯按腿部主要商业原切部位进行分割。结果显示出明显的“品种效应”，有利于BU驹马，与JN驹马相比，其记录的生产性能值和胴体性状最高。另一方面，育肥日粮有助于改善JN驹马的生产性能和胴体特征。特别是，与日粮2相比，日粮1对所分析的特征有积极影响。然而，除了蹄关节外，肉的原切部位不受品种和日粮效应的影响，各动物组之间的值相似。
