Cost Comparisons of Alternative Methods for Processing Recycled Waste Newspapers into Farm-Animal Bedding

The Feasibility of Biodiesel from Waste/Recycled Greases and Animal Fats

Biomass Gasification: An Alternative Solution to Animal Waste Management

Thermogravimetric analysis was used to examine the thermal behavior of dairy manure as a pyrolysis and combustion feedstock. Nitrogen and air were used as purging gases to analyze the pyrolysis and combustion reactions, respectively, and heating rates of 20 o C min -1 , 40 o C min -1 and 60 o C min -1 were applied. An Arrhenius model was used to estimate the kinetic parameters (activation energ...

Feasibility of Miscanthus as alternative bedding for dairy cows

Despite dairy farmers’ awareness of the importance of correct bedding for the health and comfort of their cows, they are often frugal with respect to these bedding materials in order to reduce costs. In addition, farmers are currently dependent on the availability and price fluctuations of traditional bedding materials. For these reasons, the scientific literature as well as the trade press poi...

Molecular insights into farm animal and zoonotic Salmonella infections.

Salmonella enterica is a facultative intracellular pathogen of worldwide importance. Infections may present in a variety of ways, from asymptomatic colonization to inflammatory diarrhoea or typhoid fever depending on serovar- and host-specific factors. Human diarrhoeal infections are frequently acquired via the food chain and farm environment by virtue of the ability of selected non-typhoidal s...

Comparison of bacteria populations in clean and recycled sand used for bedding in dairy facilities.

Bedding samples were collected twice from commercial dairy free-stall facilities that used recycled sand and clean sand in both the summer and winter. Collection began on the day sand was taken from the pile (d 0) and placed in the free stalls, and continued for 5 to 7 additional days. The number of colonies per gram of bedding of gram-negative bacteria, coliforms, Streptococcus spp., and Klebs...
