Livestock feed is susceptible to contamination from wildlife excreta during on farm storage. Pathogens associated with diseases such as paratuberculosis, salmonella and cryptosporidiosis are present in wild rodent and bird excreta. Feed stores on four farms in the east of Scotland were monitored monthly over the winter of 1998/9 to quantify the levels of wildlife faecal contamination. A mean of...

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 ...

FEED GRAINS ARE A GROWING AND SIGNIFICANT MARKET Livestock industries are a major market for grains on Australia’s east coast and a significant market for grain exports from WA and SA. Hafi and Connell (2003) have estimated that 80% of the annual demand for nearly 9 mmt of feed grains (cereals, oilseeds and pulses) is from livestock industries in the eastern states. An analysis of this demand i...

This study identified different roles played by urban household members in livestock production in Southeast Nigeria. Data were collected from two hundred and ten (210) livestock keepers using interview schedule. The data obtained were analyzed using descriptive statistics. The mean age of the farmers was 49.1 and a majority (86.7%) had at least primary education. A greater proportion (78.1%) o...

In the intensive livestock production systems, with decrease in grazing land and intensification of agriculture, the animal feeds are most likely to be contaminated with pesticides, dioxins, radionuclide, heavy metals, bacterial, fungal / mycotoxin contaminants etc., which may , market, it is the need of the hour to produce the livestock products free from contaminants. The feeds and fodders ar...

Livestock production impacts air and water quality, ocean health, and greenhouse gas (GHG) emissions on regional to global scales and it is the largest use of land globally. Quantifying the environmental impacts of the various livestock categories, mostly arising from feed production, is thus a grand challenge of sustainability science. Here, we quantify land, irrigation water, and reactive nit...

Quantification of biogenic carbon fluxes from agricultural lands is needed to generate comprehensive bottom-up estimates of net carbon exchange for global and regional carbon monitoring. We estimated global agricultural carbon fluxes associated with annual crop net primary production (NPP), harvested biomass, and consumption of biomass by humans and livestock. These estimates were combined for ...

Aflatoxins are a type of mycotoxin that are toxic and extremely carcinogenic. Food for human consumption and feed for livestock are routinely tested for their presence. A sensitive analytical method for the determination and quantitation of four aflatoxins using the Bruker amaZon SL Ion Trap mass spectrometry system is presented here. Specifically, this method uses LC/MS/MS to quantify aflatoxi...
