This review focuses on 3 main sources of contamination of Australian grains used in livestock feeds, namely chemical residues, moulds and mycotoxins, and weed seeds, including natural toxins such as pyrrolizidine alkaloids. By evaluating the risk to livestock from chemical contaminants (pre-emergent herbicides, selective herbicides, fungicides, insecticides used during growth phases and at pre-...

the problem of food security during the last few decades has acquired a global character. population growth, reduction of farmland suitable for agriculture and ecological factors has led to a sharp increase in food demand. in such conditions, the role of countries which are able to increase the export of agricultural production in short-term periods is rising. ukraine has great opportunities fo...

b a ckground: anaplasmosis is an important issue for animal breeders in terms of economic losses as well as a health concern to human. ticks are considered as the main vector of this disease. lack of documented information about anap lasma species in iran was the scope of this study to determine the population of ticks and the presence of anap lasma in ticks, domestic ruminants and also human b...

Human and livestock evacuation during volcanic crises is an essential component of volcanic risk management. This study investigates the evacuation of human and livestock populations from areas impacted by ashfall from the 1991 Hudson eruption, Patagonia. The eruption was one of the largest in the 20 century resulting in significant impacts on rural communities in affected areas, including the ...

Junior livestock projects provide excellent opportunities for education and positive agricultural experiences for youth. As genetic testing advances become widely available to livestock producers, youth benefit by learning about the benefits and applications of genetic testing. Market and replacement hogs can be tested for genetic defects and for performance characteristics which influence repr...

In Senegal, a project has been undertaken to eradicate a population of tsetse flies (Glossina palpalis gambiensis) from a prime area for intensifying livestock production--the coastal region of Niayes. The project is intended to remove the constraint of trypanosomosis and allow the ecological intensification of cattle production. A cross-sectional analysis of ten case studies was the inductive ...

Questions as to whether public investment in international agricultural research is a ‘Good Thing’ or not may best be addressed using two arguments: (1) justifications based on whether or not past investments have yielded substantial benefits to societies and the resource-poor; and (2) that future investments need to be made as effectively and efficiently as possible, which means they must be t...

Consumption of feedstuffs contaminated with ergot alkaloids has a broad impact on many different physiological mechanisms that alters the homeostasis of livestock. This change in homeostasis causes an increased sensitivity in livestock to perturbations in the ambient environment, resulting in an increased sensitivity to such stressors. This ultimately results in large financial losses in the fo...
