The feeding strategies of the first domesticated herds had to manage the risks arising from the novelty of livestock practices in territories often distant from the animals' primary habitats. The Iberian Peninsula is characterised by a great diversity of environments, which undoubtedly influenced these dynamics. At the beginning of the Neolithic period these led the possibility to combine diverse livestock farming practices based on different animal feeding habits. This variability is also consistent with the rythms of adoption of domesticated animals, being later on the northern area. In order to address this issue, this work focuses on the dietary regimes of early sheep herds from southern Iberia, an area for which information is currently scarce. This study utilises high-resolution radiocarbon dating and stable isotope data on teeth to investigate sheep husbandry management strategies in Cueva de El Toro (Antequera, Málaga). The radiocarbon dates on the analysed remains evidenced they were deposited at the site over a short period, supporting the recurrent use of the cave. The sequential analysis of oxygen and carbon isotopes in tooth enamel reveals distinct livestock management strategies, reproduction patterns, feeding habits, and mobility during this short period. This variability demonstrates that livestock management practices in the western Mediterranean are more diverse than previously considered. Furthermore, these findings support the hypothesis that early Neolithic communities in the southern Iberian Peninsula were able to adopt different feeding strategies within the same herd, depending on their ecological and productive needs.
最初被驯化的牲畜的饲养策略必须应对在远离动物主要栖息地的地区采用牲畜养殖新方法所带来的风险。伊比利亚半岛的环境多样,这无疑影响了这些动态。在新石器时代早期,这些动态使得人们有可能根据不同的动物饲养习惯,结合不同的牲畜养殖实践。这种多样性也与驯化动物的采用节奏一致,北部地区采用得较晚。为了解决这个问题,这项工作专注于研究伊比利亚半岛南部早期绵羊群的饮食模式,该地区目前信息匮乏。本研究利用牙齿的高分辨率放射性碳测年和稳定同位素数据,调查了安特克拉(马拉加)埃尔托罗洞穴(Cueva de El Toro)中的绵羊养殖管理策略。对分析的遗骸进行的放射性碳测年表明,它们是在短时间内在该地点沉积的,支持了洞穴的反复使用。牙釉质中氧和碳同位素的顺序分析揭示了在短时间内不同的牲畜管理策略、繁殖模式、饲养习惯和流动性。这种多样性表明,地中海西部地区的牲畜养殖实践比以前认为的更加多样化。此外,这些发现支持了这样的假设,即在伊比利亚半岛南部的早期新石器时代社区,根据其生态和生产需求,能够在同一群牲畜中采用不同的饲养策略。
