贝西是一个史前村庄坐落在塞纳河（巴黎，法国），其主要占领时期可以追溯到公元前4千年的开始。动物自给经济严重依赖畜牧业，辅之以包括绵羊在内的其他物种。牛和羊的同位素历史（三角洲C-13，三角洲O-18）进行了调查，在季节尺度上，通过连续采样的牙釉质，提供新的见解的季节性出生和饮食。绵羊在仲春产羔，只比目前在欧洲温带相似纬度地区观察到的预期稍晚。牛出生的时间跨度约为6个月，这是一个意外的结果相比，在自由放养的牛种群的两到三个月的产犊期。产犊期的延长可能与季节性食物补充有关。一些牛和羊在冬季以C-13耗尽的资源为食，可能是绿叶饲料。产犊期延长的直接后果是牛奶的供应，这将覆盖贝西全年。这是一个重要的信息，因为从牛群的人口管理来看，人们高度怀疑人类社区对牛奶的剥削。
Bercy is a prehistoric village sited by the Seine river (Paris, France), whose main period of occupation was dated to the very beginning of the 4th millennium BC. The animal subsistence economy relied heavily on cattle husbandry, complemented by other species including sheep. Cattle and sheep isotopic history (delta C-13, delta O-18) was investigated at the seasonal scale, through sequential sampling in tooth enamel, providing new insights into seasonality of birth and diet. Sheep were lambing in mid-spring, only slightly later than expected from what is observed nowadays in temperate Europe at similar latitude. Cattle were born over a period spanning approximately six months, which was an unexpected result compared with a two to three months calving period in free-ranging cattle populations. The extension of the calving period might have been related to seasonal food supplementation. Some cattle and some sheep fed on a C-13-depleted resource in winter, potentially leafy fodder. A direct consequence of an extended calving period would be the availability of cow milk, which would have covered the whole year at Bercy. This is important information in a context where the exploitation of cattle milk by the human community was highly suspected from the demographic management of the herd.
