The hardy, multipurpose Dominique chickens that came to the New World with the Pilgrims and later traveled in pioneer saddlebags to help settle the West were once too numerous to count; by 1990 a mere 500 hens survived. This is but a single example of the diminishing diversity of farm animals: half of once-common livestock breeds are endangered, others are already extinct.The need to preserve farm animal diversity is increasingly urgent, says the author of this definitive book on endangered breeds of livestock and poultry. Farmyard animals may hold critical keys for our survival, Jan Dohner warns, and with each extinction, genetic traits of potentially vital importance to our agricultural future or to medical progress are forever lost.This comprehensive book features:• complete information on the history, characteristics, qualities, and traits of 138 endangered livestock breeds (goats, sheep, swine, cattle, horses, other equines) and 53 poultry breeds (chickens, turkeys, ducks, geese)• where these breeds may be seen today• the degree of rarity of each breed in the United States, United Kingdom, and Canada• information on feral livestock populations• 160 color photographs and over 80 black and white photos and historical illustrations

Human concern about the status of genetic diversity in livestock breeds and their conservation has increased, as intense selection and reduced population sizes in many breeds has caused losses on the global livestock genetic biodiversity. Traditionally, pedigree data provided by the breeders were used to estimate genetic diversity parameters, but over the past decades, technology has made possible the development of genomic markers. The result has been new opportunities to estimate genetic diversity in more detail, and to improve selection as well as prioritizing animals for conservation of genetic resources. The aim of the review is to summarize the evolution of livestock genomic markers and to explore the potential of the newest high-throughput technologies for estimation and conservation of livestock genetic diversity. More accurate diversity parameters are observed when genomic information is used for selection decisions instead of the traditional estimates using pedigree data. It is also possible to estimate additional parameters such as linkage disequilibrium to calculate effective population size or to minimize the genetic relatedness among the selected individuals based on runs of homozygosity. For long-term perspectives, new methods on genome editing are considered as new perspectives to reach a genetic diversity balance.

Aim Wild biodiversity and agrobiodiversity are affected by challenges such as agricultural intensification. However, it is unknown whether or not both components of biodiversity respond similarly to environmental factors and to these challenges. Here, we examine the spatial relationships between the distributions of wild biodiversity and agrobiodiversity, to quantify how and where they covary across the geography. Location Mainland Spain, a European region that harbours high values of both wild and agro‐ biodiversity. Methods We used geographically weighted regression models to analyse the spatial variation in the relationships between the distribution of wild vertebrates and environmental and agrobiodiversity variables. We modelled the spatial gradients in species richness of native terrestrial vertebrates—that is, specific groups of amphibians, reptiles, birds and mammals—as a function of local livestock breed richness—that is, bovine, ovine, caprine, asinine, equine and porcine—climate variables and human footprint. Results We found significant covariation between the distribution of native vertebrate species richness and climate, human footprint and livestock diversity. Overall, the association between species richness of the four wild terrestrial vertebrate groups and local livestock breed richness is positive across most of the studied area. However, local breed richness of cattle and sheep breed displays contrasting patterns, where cattle breeds associate positively to most wildlife vertebrates and sheep breeds show negative associations. Main conclusion Wildlife diversity distributions are significantly associated with livestock agrobiodiversity. These spatial relationships are mediated by large‐scale environmental gradients. Since both, wildlife and livestock agrobiodiversity, tend to co‐occur spatially, future strategies for conservation in agricultural landscapes could benefit from integrated approaches.

As Britain industrialized in the early nineteenth century, animal breeders faced the need to convert livestock into products while maintaining the distinctive character of their breeds. Thus they transformed cattle and sheep adapted to regional environments into bulky, quick-fattening beasts. Exploring the environmental and economic ramifications of imperial expansion on colonial environments and production practices, Rebecca J. H. Woods traces how global physiological and ecological diversity eroded under the technological, economic, and cultural system that grew up around the production of livestock by the British Empire. Attending to the relationship between type and place and what it means to call a particular breed of livestock \"native,\" Woods highlights the inherent tension between consumer expectations in the metropole and the ecological reality at the periphery. Based on extensive archival work in the United Kingdom, New Zealand, and Australia, this study illuminates the connections between the biological consequences and the politics of imperialism. In tracing both the national origins and imperial expansion of British breeds, Woods uncovers the processes that laid the foundation for our livestock industry today.

Currently, there is growing interest in how livestock projects can contribute to resilience to the effects of climate change. In this article we recommend a shift away from gross productivity to sustainability, via the use of thrifty local breeds, with an additional emphasis on improving survival of young animals. These animals, due to their local adaptations, are more likely to be resilient to climate change. There is a gender dimension to these proposals, since smaller animals and local breeds are more likely to be perceived by communities as suitable for husbandry by women. We recommend a re-orientation towards an explicit gender-equality focus for these projects.

Pro-poor interventions that use agrobiodiversity for development actions are widely considered relevant only at small scales. Agrobiodiversity interventions are often left out of national-level/large-scale development planning. Scaling-up modalities include adaptation, diffusion, replication, value addition, and temporal scaling up. We undertook a review of 119 interventions that use agrobiodiversity for both the crop and the livestock sector. The interventions ranged from improving the availability of materials and information through management and market-oriented actions to changing norms and enabling policies. The interventions are also organized in accordance with farming-community goals and constraints. The open-access multilingual Diversity Assessment Tool for Agrobiodiversity and Resilience (DATAR) was created as a framework to systemize and structure agrobiodiversity interventions under different scaling-up modalities for the on-the-ground field assessment and scaling-up of agrobiodiversity interventions. The use of the framework enabled the scaling up of small-scale interventions that use agrobiodiversity to have impact on agricultural development at larger spatial and temporal scales.

The rising interest in healthier meat options prompted the exploration of alternatives to traditional pork-based products, incorporating meat from different livestock species, feeding regimens, and functional ingredients. This study investigates the production of healthier meat products by examining the physicochemical traits, fatty acid profile, and sensory properties of mortadella made with Cinisara meat of four young bulls and four adult cows, and four females of the Nebrodi Black Pig. All the animals were fed principally on natural resources. Nutritional analysis revealed different levels of moisture, protein, fat, and ash in raw materials, with pistachios contributing to a healthy fatty acid profile rich in monounsaturated and polyunsaturated fatty acids. Formulations using cow meat exhibited higher fat content and caloric value, resulting in sensory attributes such as more intense color, improved fat cube adhesion, and pronounced odors compared to young bull and control mortadella. Fatty acid analysis demonstrated distinctive profiles influenced by the meat type used and, as expected, bovine products showed higher contents of rumenic and other conjugated linoleic acids. Pork mortadella displayed greater ω6 and ω3 values, with a healthier ω6/ω3 ratio comparable to those found in cow products. Young bull mortadella showed the worse atherogenic and thrombogenic indices. The findings underscore the impact of raw materials on the nutritional and sensory attributes of mortadella, emphasizing the necessity for interventions to enhance fatty acid composition in processed meat products.

In temperate forested regions, historical agricultural production and value have been characterized by booms and busts. Agricultural diversification can encourage more stable agricultural development in the future. Agricultural Census and Survey data from 1840 to 2017 were used to estimate crop and livestock species’ product production and value for Maine, USA. These data were also used to calculate agricultural diversity indicators over time such as species richness, relative abundance, effective number of species, species diversification index, evenness, Shannon-Weiner index, and composite entropy index. Maine’s historical grass-based livestock systems included crops raised to feed livestock from the state’s establishment until the 1950’s. Since the 1950’s, production and value of livestock commodity products (e.g., meat chicken, eggs) have busted after initial booms. Three categories where diversity indicators have become more favorable since the 1950’s in Maine include livestock, livestock forage/feed, and potatoes and potato rotation crops. Mixed vegetables, fruits, nuts, and specialty crops as a category have had diversity increases during the 1970’s back-to-the-land movement and over the past two decades. Floriculture, propagation, and X-Mas trees as a category have witnessed volatile diversity indicator changes over time. Past diversification strategies can inspire farmers to go “back to the future” to improve sustainability.

There is an increasing interest in assessing livestock breed contributions to ecosystem services (ES) and including this knowledge in decision making. However, this task has been limited due to the complexity of the multidimensional relationship between livestock diversity and ecosystem services. In this work, we elaborate on the livestock breed characteristics central to developing a comprehensive approach to livestock breed inclusion in the ecosystem services framework. Thus, we explore the multidimensional nature of livestock breeds, i.e., as eco-cultural entities, biodiversity components, and drivers of livestock system heterogeneity and functioning. First, anthropogenic and natural factors have acted jointly to develop breeds as eco-cultural entities. This fact represents an opportunity to move toward farming system sustainability by Nature-Based Solutions and Nature’s Contribution to People paradigms. Second, livestock breeds are components of biodiversity, and as such, can be framed as goods, as final ecosystem services, and as regulators of ecosystem processes. Third, livestock breeds contribute to livestock system heterogeneity and resilience. By integrating these aspects, we might better understand how livestock breeds provide and modulate ecosystem service provision and, therefore, how to improve breed conservation and livestock policies toward farming system sustainability.
