M. Balasse et al., EMERGENCE OF DAIRY PRODUCTION IN THE NEOL ITHIC - CONTRIBUTION OF ISOTOPIC ANALYSIS OF CATTLE ARCHAEOLOGICAL BONES, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 325(12), 1997, pp. 1005-1010
A study of intra-individual variability of nitrogen isotopic compositi
on of bone collagen from cattle mandibles from the neolithic site of B
ercy (Paris, IVth millenium BC) showed that the young bovines were wea
ned at an age between 6 and 12 months old. The examination of the mort
ality profile shows that the young were slaughtered at this age. The o
btained results do not contradict the 'post-lactation' peak hypothesis
, which could be the evidence for an economy oriented towards dairy pr
oduction.
