- Abstract:
- ... The environmental performance of various aspects of animal origin food supply chains has been the focus of research in recent years, and has provided useful information. However, there were no studies that covered the entire egg supply chain from different perspectives. The aim of this study was to analyze the majority of environmental impacts in the table egg supply chain comprising of three subs ...

- Abstract:
- ... If we use farm animals for what they are good at - converting by-products from the food system and grass resources into valuable food and manure - they can contribute significantly to human food supply, while at the same time reducing the environmental impact of the entire food system. By converting these so-called low-opportunity-cost feeds, farm animals recycle biomass and nutrients into the foo ...

- Abstract:
- ... The insufficient food supply due to low agricultural productivity and quality standards is one of the major modern challenges of global agricultural food production. Advances in conventional breeding and crop domestication have begun to mitigate this issue by increasing varieties and generation of stress-resistant traits. Yet, very few species of legumes have been domesticated and perceived as usa ...

- Abstract:
- ... The endosperm of cereal grain forms the staple diet for most of the world’s population, and feeds much of their stock. Grain size and quality are determined largely by events taking place during coenocytic nuclear division, endosperm cellularisation and cell differentiation, and the production of storage molecules. Thus, understanding the complex signalling processes occurring at each of these ste ...

Deforestation associated with agricultural expansion, particularly that of extensive cattle ranching, remains a pressing challenge for sustainable development and climate mitigation efforts in South America. In response to these challenges, national and local governments, as well as private and non-governmental actors, have developed new forest conservation governance mechanisms. In addition to re ...

- ... The production of protein from animal sources is often criticized because of the low efficiency of converting plant protein from feeds into protein in the animal products. However, this critique does not consider the fact that large portions of the plant-based proteins fed to animals may be human-inedible and that the quality of animal proteins is usually superior as compared with plant proteins. ...

Human-derived foods could directly impact population sizes or indirectly affect them by mediating the influence of another factor, such as disease. In 1994, a novel disease outbreak (mycoplasmal conjunctivitis) substantially reduced popula ...

- Abstract:
- ... The past couple of decades have provided considerable details on fungi and the toxins that they produce, as well on the mechanism of toxin action, toxicity and effects on animal and human health. But, since they are natural contaminants, their presence is often inevitable. Fusaria are widespread in all cereal-growing territories of the world, but they are especially common in our geographic area. ...

- Abstract:
- ... Since the discovery of the fumonisins in 1988, extensive academic studies have generated much knowledge, including data on chemistry, biochemistry, toxicology, methods of analysis, natural occurrence in food supplies, fate during various processing procedures, and human and animal exposures. These mycotoxins have also been assessed by the International Agency for Research on Cancer (IARC) and have ...

- Abstract:
- ... Food security has determined the history of mankind. The global population will increase to about 9 billion during the next four decades. Food and feed demands have been projected to double in the 21st century, which will further increase the pressure on the use of land, water and nutrients. Clearly, there are gaps in our knowledge regarding the global capacity for a sustainable plant-based produc ...

- Abstract:
- ... Antimicrobials used in poultry production have the potential to bioaccumulate in poultry feathers but available data are scarce. Following poultry slaughter, feathers are converted by rendering into feather meal and sold as fertilizer and animal feed, thereby providing a potential pathway for reentry of drugs into the human food supply. We analyzed feather meal (n = 12 samples) for 59 pharmaceutic ...

- Abstract:
- ... Improvements in feed conversion efficiency (FCE) can be applied to individual animals as well as to production from land, as in a farm system. Our focus relates mainly to food production from individual animals within any animal population where there is divergence in the efficiency that individuals use ingested feed for maintenance and production; primarily due to differences in digestion and met ...

The objective of the study was to describe the diet composition of western barbastelle bat (Barbastella barbastellus), its seasonal changes and main factors determining trophic niche of the species. Barbastelle bat feeds predominantly on moths and has the narrowest trophic niche within the entire studied bat community. A comparison of the food supply and the diet composition showed selectivity for ...

- Abstract:

A better understanding may provide useful information for the development of the aquaculture of this species. Currently, A. mollis is being co-cultured beneath mussel farms and it is not clear if it can effectively use the wide natural variation in the food availability ...

- Abstract:
- ... Humanity is quickly encroaching upon the finite limits of the biosphere. As our numbers and appetites grow, food supplies become less secure, reserves of clean energy dwindle, pools of freshwater evaporate, the atmosphere's capacity to absorb our emissions diminishes and space for human and biotic habitat grows scarce. In response, some are now asking whether the biosphere can support our growing ...

- Abstract:
- ... The distribution range of fishes along an upstream–downstream gradient within a river basin is determined by the ecological requirements of each fish species. This differential pattern of distribution may suggest the occurrence of fish zones, where different functional guilds would prevail. The earliest concept of fish zonation highlighted the preferential position of several species in European r ...

The model includes biomass supply from annual crops on arable land, short rotation forestry (willow) and plantation forestry. Crop area distributions were simulated using cost data for year 2005. Five scenarios with different constraints, e.g. on foo ...

As we progress through the technology era, certain agricultural technologies [e.g. genetically modified (GM) crops] have been championed to maximise production while minimising environmental impact. Yet, multi ...

Here I address the trade-offs between gains and risks and the question of how much and how fast to swim using simple models that optimise the number of lifetime mate encounters. Radically different swimming strategies are predicted for different feeding beh ...

The high incidence of scale worms in the diet is unusual for shags; they were taken by all birds in the non-breeding season but in the breeding season those feeding young changed to a diet of fish. The fish were generally small nototheniids that are easy to transfer from adult to young. Diving data for breeding and n ...

The Red—backed Sandpiper (C. alpina), studied in five seasons near Barrow, Alaska, 71°N, feeds largely on larvae and adults of the families Tipulidae and Chironomidae (Diptera). Sampling for availability and abundance of insect populations shows that the food source readily availabl ...
