Limnology and Oceanography, EarlyView.Abstract Stream water nutrient ratios are often influenced by flow variation and landscape characteristics. However, the influence of these drivers on total and dissolved nutrient ratios remains understudied, especially in prairie ecosystems where hydrologic connectivity between soils and streams exhibits substantial spatial and seasonal variability ...

The nasopharyngeal microbiota of feedlot cattle [PDF]
Scientific Reports, 2015 AbstractThe bovine nasopharyngeal tract plays an important role in animal health and welfare by acting as a site for the carriage of pathogens causing bovine respiratory disease, a condition which results in significant morbidity and mortality in feedlot cattle. We characterized the bacterial nasopharyngeal microbiota in cattle at feedlot entry (day 0)

Seasonal decomposition and the effect of clothing in Cape Town, South Africa
Journal of Forensic Sciences, EarlyView.Abstract Unidentified, unclaimed human remains are a substantial problem in many developing nations, including South Africa. Most forensic cases in Cape Town involve clothed individuals found in thicketed environments. To assist in local medico‐legal death investigations, we gathered taphonomic data on six clothed and four unclothed 60 kg porcine ...

Comparing breeds of sheep in the feedlot or on pasture and in the feedlot
, 2018 A terminal sire study was conducted to evaluate production and carcass traits of Texcl sired offspring compared to Suffolk and Columbia offspring. Breeding and lambing occurred on pastures during a 2-yr study. The Iambs were weaned at an average age of 70 and 94 d and allocated to one of two finishing programs.

Annals of Applied Biology, EarlyView.The forage digestibility decreases in the dry season. Fungus isolates from the gastrointestinal tract of healthy sheep were evaluated. Aspergillus terreus isolate was identified by analysis of rDNA and encoding β‐tubulin gene and Trichoderma longibrachiatum was identified by analysis of rDNA and elongation factor 1‐α gene. The T.

Spatial price competition and buyer power in the U.S. beef packing industry
American Journal of Agricultural Economics, EarlyView.Abstract We develop a spatially‐explicit model of the U.S. beef packing industry to study key questions related to competition in an oligopsony setting. Cattle supplies are modeled at the county level, and packing plants' location, capacity, and ownership are taken as given. Packers procure negotiated cattle by competing in prices in each local (county)

Timing of eating during transition impacts feedlot cattle diet and liveweight gain
Animal, 2021 The timing of eating, relative to when feed is offered, is affected by the social rank of feedlot cattle due to limited feed bunk space. As cattle can select feed based on dietary preference, the timing of eating for cattle in feedlot may be associated ...
