Escherichia coli is widely considered to not survive for extended periods outside the intestines of warm-blooded animals; however, recent studies demonstrated that E. coli strains maintain populations in soil and water without any known fecal contamination. The objective of this study was to investigate whether the niche partitioning of E. coli occurs between cattle and their pasture. We attemp...

This paper considers the potential problems that may militate against the adoption of organic poultry production in Nigeria. Factors identified include: higher risk of diseases like coccidiosis and Newcastle disease, disease prevention and control / herd health management, disease containment in times of outbreak, land acquisition (land tenure system), market economies / cost-benefit ratio, pas...

Sulfur (S) is a requisite part of the ruminant diet, but may sometimes be present in excess, leading to decreased animal performance and illness. In this experiment, 96 crossbred yearling steers (321 ± 29 kg BW) were used to determine the effects of dietary S concentration of a supplement fed to cattle on pasture and of the total diet in the finishing period. Steers were blocked by weight and a...

one of the most important issues in dairy farm is feed management which aims to manage available and required feed. There are several problems associated with managing cattle feed such as how to best satisfy feed deficits or how to utilize extra feed available. Since early 70s, feed planning decision support systems have been developed to help farmers addressed issues. However, many of those sy...

This article investigates the behavioral drivers of pasture creation and associated implications for deforestation in a 22,000 km2 agricultural frontier spanning the base of Mexico‘s southern Yucatán. After developing a theoretical model that highlights the role of social networks and information spillovers with respect to the decision to begin cattle ranching, we use household data to estimate...

To estimate relative risk for exposure to ticks infected with Lyme disease-causing spirochetes in different land-use types along a trail in Germany, we compared tick density and spirochete prevalence on ruminant pasture with that on meadow and fallow land. Risk was significantly lower on pasture than on meadow and fallow land.

Post-slaughter muscle energy metabolism meat colour of South African production systems were compared; steers (n=182) of Nguni, Simmental Brahman crossbreds were reared on pasture until A-, AB-, or B-age, in feedlot until A-AB-age. After exsanguination carcasses were electrically stimulated (400 V for 15 s). M. longissimus dorsi muscle energy samples were taken at 1, 2, 4 and 20 h. Post-mortem ...

During recent years, there has been interest in once-a-day (OAD) milking. A comparison was made of OAD with twice-a-day (TAD) milking on a case study farm in northern Victoria. The comparison suggests that operating profit and internal rate of return are similar to TAD milking if the decrease in milk protein plus fat production, as a result of OAD milking, is less than 12 percent. Although a de...
