Small mammals can be an important bioindicator of ecosystem health. They serve as both predator and prey in many ecosystems. By means of live trapping and nest monitoring, we studied the ecological relationships between small mammals, avian nest survival, and vegetation composition and structure on six private ranches in the Sandhills of Nebraska during 2004. Our study documented six species (1...
BACKGROUND Hypoglycin A, found in seeds of Acer negundo, appears to cause seasonal pasture myopathy (SPM) in North America and is implicated in atypical myopathy (AM) in Europe. Acer negundo is uncommon in Europe. Thus, the potential source of hypoglycin A in Europe is unknown. HYPOTHESIS AND OBJECTIVES We hypothesized that seeds of Acer pseudoplatanus were the source of hypoglycin A in Europ...
Abstract Native to Europe and Central Asia, face flies (Musca autumnalis De Geer, Diptera: Muscidae) were unintentionally introduced into North America became pests of pastured beef cattle, dairy horses. Female male use their sponging proboscis with prestomal teeth feed around moist, mucus membranes an animal’s other body parts. While feeding, agitate livestock elicit defensive behaviors (e.g.,...
Attention to the quality and quantity of forage plants, palatability and species preference, are among the information needed to properly manage pasture grazing. One of the prominent plants in the Nour Rud rangelands are Allium spp plants that have an acceptable distribution in the area. For the sake of the study, the preferred value of different species of Allium’s for Shal sheep with an avera...
Grazing Deferment Effects on Forage Diet Quality and Ewe Performance Following Summer Rangeland Fire
Complete rest or grazing deferment is a general recommendation to encourage vegetative recovery following fire in the western United States. However, effects of grazing deferments on animal performance have not been determined. Prescribed fires were individually applied to nine separate, 1.5-ha pastures each year (2006 and 2007) for a total of 18 pastures. Grazing was deferred until spring (16 ...
Introduction Animal husbandry and livestock raising as the most important agricultural sub-sector reduces poorest peoplechr('39')s vulnerability all over the world by providing them a "food safety network". In this regard, ranchers are facing key challenges such as low yields of cattle, lack and fragmentation of pasture, water shortage and need to irrigate pastures and meadows, competition for...
