Tradeoffs and co-benefits among impacts of contrasting livestock systems
Livestock farming generates some striking externalities; whilst it provides 30% of human dietary protein, it occupies 75% of agricultural land, emits 14-17% of anthropogenic greenhouse gas emissions, and uses more antimicrobials than human medicine. Demand for livestock products is high and rising, …

Epidemiology of East Coast Fever in smallholder livestock systems of East Africa
The health and productivity of livestock are pivotal in rural livelihoods across sub-Saharan Africa, providing nutrition, income and employment. However, infectious diseases, particularly those caused by haemopathogens, pose a significant threat to their health and productivity. Haemopathogens …

Investigation of the Role of Amide I to Amide II Ratio and Alpha Helix to Beta Sheet Ratio of Faba Bean Seeds in the Determination of Microbial Protein Synthesis and Animal Performance and Metabolism in Ruminant Livestock Systems.
The food and feed industries have benefited from the application of Infrared Spectroscopy as spectral features have been associated with nutrient quality and degradation characteristics. To our knowledge, the effects of steam pressure toasting (SPT) duration on spectral features of Faba bean seeds …

Precision Technologies and Data Analytics for Monitoring Ruminants
… population. Despite notable advancements in the livestock industry, there is a rising demand for animal protein products and a pressing need for sustainable practices. Consequently, it is imperative to focus on improving efficiency and sustainability across the environmental, economic, and social …

Establishment of native plant species for livestock forage in silvopasture systems
… environmental stewardship into existing forage-livestock systems is growing in popularity. This project takes a novel approach incorporating native rather than introduced forage species. Our objectives were to: determine success of establishment of native cool and warm season grasses, and native …

The development of a strategic approach to managing diffuse pollution
… Key sectors investigated included arable and livestock systems in agriculture, urban development, industrial estates and transport. Physical measures to address the sources of diffuse pollutants were focused on best management practices (BMPs), following the concept developed in the USA. The …

Exploring the potential of duckweed (Lemnaceae) as a circular protein crop on agri-food industry wastewaters
… putting significant strain on food production systems. Current livestock systems are inherently inefficient and require large inputs of plant proteins (e.g., soybeans), the cultivation of which is unsustainable. Policies such as the European Union ‘Green Deal’ and the ‘Protein Strategy’ aim to …

A model of a rangeland grazing system within a management procedure approach framework
A model describing livestock grazing system dynamics was developed and fitted to available data. This study preliminarily explored the use of a formal management procedure (MP) approach to determine appropriate annual offtake in a terrestrial system. This approach has been applied in marine systems …

Brazil’s Soy Moratorium: Current Expansion Capacities, Extension to the Cerrado, and Increasing Compliant Production
… current lands, and introducing integrated-crop-livestock systems with soy (ICLS) onto established pasture. We find 18.0 Mha of additional remaining eligible area in the Amazon and a hypothetical 67.9 Mha in the Cerrado, of which 81.0% and 62.3%, respectively, are estimated to be suitable for soy …

Diversity Relationships in Native, Warm-Season Plant Communities used for Agriculture
… the use of native, warm-season plants in forage-livestock systems using a pool of ten native species. The first, a large-scale, three-year, experiment tested three different NWSP mixtures (switchgrass monoculture, a four-grass mixture, and a ten-species mixture) and two management methods (grazed …

Effect of Grazing Pressure on Cattle Grazing Cool Season Annual Forages
… from land resources. Integration of cropping systems and cattle production systems by use of crop biomass as a forage resource to cattle can allow greater efficiency of use of land resources. Historically, integrated crop and livestock systems were prevalent in the United States, but recent …

Demonstrating Short-term Impacts of Grazing Cover Crops on Soil Health in South Dakota
… rivers. Therefore, the need for integrated crop livestock (ICL) practices that can protect the region’s native prairies are strongly encouraged. Introducing livestock into arable cropping systems can improve nutrient cycling, soil health, and provide economic benefits. However, the detailed …

Combining field experiments, modeling, and analytics for integrated crop-livestock system management
Integrated crop-livestock systems have been suggested as a promising means for diversifying agricultural production as an alternative to specialized cropping systems in modern agriculture. In the U.S. Corn Belt, tremendous amounts of corn residues left on the land after harvest represent a vast …

Lamb performance, behavior, and body temperatures in hardwood silvopasture systems
Trees in silvopastures may provide forage-livestock systems with multiple goods and services, including shade, shelter, and browse. Reports of forage and animal productivity from these systems indicate that, in some cases, animal gains are similar or better despite lower forage yield. The …
