The Neolithic communities of the Iberian Peninsula were already strategically and efficiently managing cattle herds 6,000 years ago, moving them from low pasture lands to mid-mountain regions to guarantee their food supply, and deliberately modifying their reproductive cycle.

These are the findings of researchers from the Universitat Autònoma de Barcelona (UAB) and Cardiff University, who for the first time have used biomolecular studies to reconstruct mobility, feeding and reproduction patterns in cattle herds of the Middle Neolithic period, based on remains found in the Cove de les Pixarelles (Tavertet, Osona).

The study, published in the journal PLOS ONE, sheds light on the management strategies of prehistoric cattle herds and reveals an efficient pasturing system adapted to the environment’s characteristics. It is also the first study to identify a vertical seasonal herd mobility of this species (Bos taurus) in the Iberian Peninsula during the Neolithic period.

The research team used advanced isotopic analysis techniques and archaeozoological studies to reconstruct the mobility, vital cycle and feeding patterns of the animals. They conducted the studies with the remains of individuals dating back to 3942 and 3632 BCE, found in the Pixarelles Cave.

This site, found near the town of Tavertet (Osona), is located at 670 meters above sea level in a mountainous region that is characterized by the well-documented conservation of animal remains. The large amounts of Bos taurus remains, which represent approximately 80% of the total of animal remains recovered, make it a unique site in all of the peninsula, and particularly relevant in the study of the Middle Neolithic period (4500–3500 BCE).

The findings indicate that Neolithic communities using the Cova de les Pixarelles strategically managed their herds, moving them seasonally from low pasture lands to mid-mountain regions. This vertical mobility was combined with an ecological division of the herd: Some animals were kept close to the site to ensure reproduction and access to milk, while others were sent to rich pasture lands found further away.

The cattle’s diet was based mainly on C3 plants, found in open lands and mountain meadows. The carbon and nitrogen isotope analyses show that there were no signs of complementary feeding or intensive exploitation of pasture lands under these human communities.

“This fact reinforces the hypothesis of an efficient management with little direct intervention,” states Roger Alcàntara Fors, researcher of the UAB Archaeological Research Group on the Mediterranean and Middle East (GRAMPO) who directed the study.

The study also identified a deliberate modification of reproductive cycles. Births were synchronized with the arrival of summer pastures, coinciding with the abundance of fresh pasture and eliminating the need to supplement with feed during the winter. This strategy also maximized milk production at key times.

The results “are the only data currently available on cattle herd management for Middle Neolithic chronologies in the Iberian Peninsula,” says Alcàntara Fors.

According to researchers, the study highlights the complexity of livestock strategies in the Middle Neolithic and the adaptive capacity of communities in diverse natural environments, and contributes to understanding how cattle were integrated into the economic and social changes of the period studied.

They also highlight the fact that it establishes a basis for future research on human resilience to mountain landscapes and the socioeconomic dynamics of this key period in human history.
