BACKGROUND Alterations in lipid metabolism occur when animals are exposed to different feeding systems. In the last few decades, the characterisation of genes involved in fat metabolism and technological advances have enabled the study of the effect of diet on the milk fatty acid (FA) profile in the mammary gland and aided in the elucidation of the mechanisms of the response to diet. The aim of...

Semi-arid rangelands show much spatial heterogeneity, with some parts producing more and better quality food for herbivores. The concepts of ‘Key Resource’ and ‘Key Resource Area’ have been developed to describe a resource that ‘provides good-quality forage’ and that ‘reduces (inter-)annual variation in forage supply’. Illius and O’Connor (1999) formalised these concepts, arguing that in key re...

Food waste stemmed from food contamination and ineffective quality control is a significant challenge to food management. Supply chain traceability has become an essential task of the food industry for guaranteeing food quality and safety and reducing food waste. Radio Frequency Identification (RFID) has emerged as a lead technology in the development of traceability systems, which enable autom...

Many different drivers, including productivity, ecosystem size, and disturbance, have been considered to explain natural variation in the length of food chains. Much remains unknown about the role of these various drivers in determining food chain length, and particularly about the mechanisms by which they may operate in terrestrial ecosystems, which have quite different ecological constraints ...

Large scale use of groundwater for irrigation which is often Arsenic laden, during past two decades, has given rise to the apprehension that this may be resulting in higher Arsenic intake through the food chain. This work was undertaken to determine the trend of average Arsenic exposure of the population in Bangladesh during the period 1990-2010. Based on available data on individual food items...

With the improvement of people’s living standards, the food safety issue occurs frequently. How to identify all kinds of risks, evaluate these risks scientifically and manage the risk control effectively are the challenge for each sully chain manager and the relevant researchers. In order to reduce the occurrence of the food safety issues and ensure the quality of the people’s life, it is neces...

Recent theoretical studies have shown the potential for chaotic dynamics in simple three-species food chains. Most of these studies have focused on linear food chains, although natural food chains are seldom isolated from the surrounding food web. There is a growing awareness that food web dynamics can be strongly influenced by the behavior and movement of predators, energy, and nutrients acros...

A growing number of consumers are concerned with the impacts of consumption choices. Local food supply chains are increasingly being discussed for their potential to overcome the impacts of global and more industrialized chains. However, opposition between local and global food systems is being questioned and distinctions are ambiguous. Can sustainability performance be assessed in relation to ...
