Mediterranean sheep systems review spotlights Gentile di Puglia: full analysis

A new review in Animals examines small-ruminant farming in the Mediterranean’s marginal areas through the lens of the Gentile di Puglia sheep, an old Apulian breed now under clear conservation pressure. The authors, Rosaria Marino, Mariangela Caroprese, and Marzia Albenzio, describe a production model with real strategic value, especially for biodiversity, landscape stewardship, and high-value regional foods, but one that is increasingly exposed to structural weakness and climate stress.

The backdrop is a long decline in traditional Mediterranean pastoral systems. In Apulia, Gentile di Puglia sheep were historically tied to transhumance between lowland and mountain pastures, and after World War II the breed reportedly reached nearly 1 million animals in southern Italy. Since then, the collapse of the wool economy, lower milk productivity relative to more specialized breeds, the shift away from transhumance, and crossbreeding with more productive lines have all contributed to a steep contraction. A 2024 review on Apulia’s native sheep and goat breeds put the current registered population at about 4,500 animals, while a 2023 conservation paper cited roughly 4,000 animals in Italy based on 2022 census data.

That broader context helps explain the review’s SWOT-style framing. Its core message is that Mediterranean livestock systems still have meaningful strengths: native breeds adapted to drought and low-input conditions, certified and niche products, and ecosystem services tied to grazing. At the same time, the weaknesses are familiar to anyone working in remote livestock regions, including aging rural communities, poor infrastructure, low productivity, and dependence on public support. The threats are also mounting, particularly climate change, market volatility, and competition from intensive systems. (mdpi.com)

Research around the Gentile di Puglia breed adds detail to that picture. The Apulia biodiversity review describes the breed as multipurpose, with milk used in traditional cheeses, lamb meat marketed as light lamb, and wool still recognized for fine fiber quality. More recent genetics work suggests the breed retains moderate to high genetic diversity despite its reduced numbers, which is encouraging for conservation planning. Other recent work has also focused on wool quality and on coordinated in situ and ex situ conservation, showing that the breed is attracting renewed scientific attention beyond simple historical interest.

Industry and research reaction appears to be moving in the direction the review recommends: preserve the breed, improve its economic relevance, and use modern tools to support traditional systems. A 2023 Animals paper on new conservation strategies highlighted ultrasound-based reproductive management, cryobanking, and other biotechnologies as practical tools for safeguarding Gentile di Puglia genetics. The same paper noted that Italy still lacks a fully developed national animal genetic resources gene bank, although regional and institutional efforts have advanced, including registration in 2023 of an animal germplasm cryobank in the national biodiversity registry. Separately, the breed’s Slow Food Presidium designation, noted in the 2024 Apulia review, suggests an effort to link conservation with market recognition. (mdpi.com)

Why it matters: For veterinary professionals, this is a reminder that the future of small-ruminant practice in marginal regions may depend as much on systems thinking as on individual-animal medicine. Vets serving these flocks are often the professionals connecting reproductive efficiency, parasite and disease management, welfare, traceability, and breeding decisions. In vulnerable local breeds, those decisions can shape not just farm economics, but also whether a population retains enough genetic diversity to remain viable. The review’s message aligns with a wider shift toward seeing native breeds as part of climate resilience and rural land management, not only as lower-output animals in difficult terrain. (mdpi.com)

There’s also a practical public-interest angle. Extensive native-breed systems in Mediterranean landscapes are increasingly discussed as providers of ecosystem services, including vegetation control, biodiversity support, and lower wildfire fuel loads. That gives veterinarians, animal scientists, and policymakers a stronger shared rationale for preserving these flocks, especially as heat, drought, and rural depopulation intensify pressure on marginal farming systems.

What to watch: The next question is whether review-driven attention translates into durable funding, breeding programs, and veterinary support for native breeds like Gentile di Puglia, and whether tools such as genomics, reproductive technologies, and product differentiation can make conservation economically workable on farm.
