The effect of protection from sheep grazing on indigenous plant species in relatively mesic, strongly modified Poa cita grassland, was examined using paired grazed and ungrazed sites. Ungrazed sites, fenced at times ranging from four to more than 24 years ago, had fewer species, lower indigenous cover and lower tussock density than adjacent grazed sites. The dominance of adventive species, part...

In mid-season prime lamb production it is essential to optimise lamb performance from grazed pasture to minimise costs and so improve margins from sheep production. This is achieved by continuously supplying high feed value herbage for the duration of the grazing season. Feed value is a combination of nutritive value (i.e. digestibility) and intake characteristics (which is a combination of her...

Runoff from a cow-calf pasture in eastern Nebraska was monitored for total coliforms (TC), fecal coliforms (FC), and fecal streptococci (FS) during 1976, 1977, and 1978. Bacteriological counts in runoff from both grazed and ungrazed areas generally exceeded recommended water quality standards. The FC group was the best indicator group of the impact of grazing. Rainfall runoff from the grazed ar...

Soil is the main matrix which contributes to the transfer of environmental pollutants to animals and consequently into the food chain. In the French West Indies, chlordecone, a very persistent organochlorine pesticide, has been widely used on banana growing areas and this process has resulted in a long-term pollution of the corresponding soils. Domestic outside-reared herbivores are exposed to ...

CASE REPORT Vitamin A deficiency was diagnosed in a herd of 97 19-month-old Braford heifers in the Mitchell Grass Downs (Astrebla spp.) bioregion of Hughenden in north-western Queensland during November 2015. Two heifers died after a 48-h history of sternal recumbency and of the 19 that had neurological signs, 7 were blind. Histological changes in the optic nerves of the two necropsied cattle w...
