Comparison of grazing behaviour, dietary overlap and performance in non-lactating domestic ruminants grazing on marginal heathland areas

Grazing behaviour and performance of lactating suckler cows, ewes and goats on partially improved heathlands.

The foraging behaviour (grazing time and diet composition), live-weight (LW) changes and parasitic infection (faecal egg counts of gastrointestinal nematodes) of 12 beef cows, 84 ewes and 84 goats suckling their offspring, managed in mixed grazing on heathlands with 24% of improved pasture of perennial ryegrass-white clover, were studied during the years 2003 and 2006. The results showed that g...

Mineral status of range plants for grazing ruminants in semi-arid areas of isfahan province

Intake and performance of lactating cows grazing diverse forage mixtures.

Twenty multiparous Holstein cows in midlactation grazed pastures of 4 forage mixtures in a 12-wk study repeated during 2 grazing seasons to determine if forage mixture complexity affected intake and productivity of lactating dairy cows. The forage mixtures were 1) orchardgrass plus white clover [2 species (SP)]; 2) orchardgrass, white clover, and chicory (3SP); 3) orchardgrass, tall fescue, per...

Toxicity of Crepis lacera in grazing ruminants

BACKGROUND Crepis lacera is a plant from the Asteraceae family that is common in the Mediterranean region. Farmers believe that this plant may be deadly to small ruminants in areas of southern Italy. However, scientific evidence is lacking, and no proof exists that C. lacera is toxic to ruminants. Necropsies conducted on four sheep revealed lesions in their livers and kidneys. RESULTS In the ...

Influence of Domestic Livestock Grazing on

20 In a pilot study, I observed a relationship between domestic livestock grazing and location of 21 American pika (Ochotona princeps) haypiles in the eastern Sierra Nevada and several Great 22 Basin mountain ranges. Where vegetation communities adjacent to talus bases (forefields) were 23 grazed, mean distance from talus borders to closest fresh haypiles was 30.1 m (SD = 18.9 m, n = 24 27), an...
