Footrot is an ovine foot disease of infectious origin and a cause of serious welfare and economic compromise in affected animals and flocks. The development of footrot in sheep is associated with the infectious agent Dichelobacter nodosus, which may invade as a primary pathogen, but the risk of disease is increased following damage to the interdigital skin of the foot. In this study, we used da...

The calcareous xerothermic grasslands of the Festuco-Brometea class are among most endangered Natura 2000 sites in Europe. greatest threats include a lack grazing, secondary succession, and invasive alien expansive native species. abandonment such is caused by low nutritional value biomass, as well difficult habitat conditions. aim this study was to assess physiological responses sheep breeds h...

information on animal daily forage needs is essential for an estimation of rangeland grazing capacity. accordingly, weight and animal unit equivalent (aue) for each individual class of animal should be determined. live weights of baloochi sheep as based on average live weights of 3 and 4 year old ewes were determined. five herds of baloochi breed sheep were selected for the task. in each herd, ...

Cover crops are a suite of non-marketable plant species grown to improve soil quality. They may have additional benefits including reduced weed pressure and enhanced habitat for beneficial arthropods, but they do not provide direct revenue. Integrating sheep grazing for cover crop termination could make the use of cover crops more economically feasible. However, if grazing shifts biological com...

Granulocytic Ehrlichia infection in sheep is common in Norway in areas with Ixodes ricinus. In this study, 2 sheep flocks that had been grazing on I. ricinus infested pastures the previous season, were blood sampled after being housed indoors for nearly 6 months during wintertime. Thirty animals from each flock were examined for granulocytic Ehrlichia infection in the peripheral blood by blood ...

We assessed the effects of overgrazing by feral sheep on watersheds on Santa Cruz Island, California. Overgrazing had a marked effect on stream flow; flows were much greater in overgrazed than in lightly grazed watersheds early in the rainy season, but the difference vanished later in the season. This pattern can be explained by reduced infiltration and increased surface runoff of rainfall in o...

the aim of this study was to provide preliminary quantitative information on selenium and iodine statusof sheep in markazi province, iran. selenium and iodine status of grazing sheep were measured for 57different flocks in 14 regions over one year. the districts were selected to represent major sheep growingareas in the province. blood samples were collected from 2 to 3-year-old ewes during sum...

Five sheep were fed a 10% locoweed (Oxytropis sericea) pellet or alfalfa pellets for 3- to 5-wk periods to determine the effects of intermittent locoweed ingestion on operant responding; three controls were fed alfalfa pellets for 22 wk. Sheep were trained to respond to a multiple schedule with a fixed ratio (FR) 5 and fixed interval (FI) 50 s as major elements; performance was reinforced with ...

Phosphate mining operations in southeastern Idaho have exposed selenium (Se) that was originally sequestered in the subsurface. Sheep grazing in these areas have died as a result of high Se concentrations in forage and water. This study was designed to monitor the health status of sheep grazing in a natural environment with known elevated levels of Se. A total of 72 Columbia x Suffolk sheep wer...
