Changes in vegetation from 1990 to 2000 were examined at 10 high country localities, representing four grassland types: fescue tussock (Festuca novae-zelandiae), snow tussock (Chionochloa rigida), red tussock (C. rubra), and silver tussock (Poa cita). At each locality, three treatments were established: ambient sheep+rabbit grazing, rabbit grazing only, and no grazing. The mutivariate methods o...

An outbreak of sheep pox occurred in December 2001 on a sheep breeding farm in Jammu, India. The farm maintains three exotic breeds of sheep, i.e. American Merino, Rambouillet and Australian cross. The disease agent was confirmed as sheep pox virus by clinical and post-mortem examination as well as laboratory testing. Typical pock lesions were dispersed over the body of the affected animals wit...

Serum samples of 749 sheep from 75 sheep flocks in Norway, i.e. 361 lambs (6 to 7 months old) and 388 adults (> 1.5 year), were analysed for antibodies to Ehrlichia equi. Ten animals from each flock were examined. Seropositive animals were found along the coast of southern Norway from Vestfold to Sør-Trøndelag (as far north as 63 degrees 38'N). Seropositive sheep were not found in southeast, ea...

Agroecological practices can improve the functioning of livestock farming systems by optimizing their underlying biological processes. Sheep/cattle mixed-grazing is an example such a practice in which sheep grazing with cattle achieve higher liveweight gain (LWG), than alone. We conducted experiment to assess relative roles parasite dilution and forage niche complementarity improving LWGs. used...

Grazing management to reduce soil erosion is paramount for preserving and enhancing grassland health under pastoral livestock production systems. However, as the focus of these systems increase productivity, inclusion its complexity in grazing has been usually neglected. Detailed consideration spatio-temporal susceptibility may be best approached with simulation modelling. To understand explore...

Mixed grazing systems combining sheep and cattle have shown better growth performance for one or both species. This observation has been attributed to their complementary feeding behaviour and the reduced host infection by gastrointestinal nematodes. Less attention has been paid to mixed grazing systems combining goats and cattle. Here, continuously grazing goats mixed with cattle (M) were comp...

Shiga toxin-producing Escherichia coli (STEC) strains possessing genes for enterohemolysin (ehxA) and/or intimin (eae), referred to here as complex STEC (cSTEC), are more commonly recovered from the feces of humans with hemolytic uremic syndrome and hemorrhagic colitis than STEC strains that do not possess these accessory virulence genes. Ruminants, particularly cattle and sheep, are recognized...

A 3-yr study was conducted in North Sumatra, Indonesia, as part of an evaluation of the feasibility of integrating sheep and rubber production. The objective was to evaluate the effects of increasing energy supplementation on reproduction and other performance criteria of Javanese Thin-Tail sheep grazing volunteer forages under 8- and 14-yr-old rubber trees. The control group was unsupplemented...

this research was conducted to recognize sibak-sardab watershed rangeland potentials, evaluate and determine of suitability classes for sheep grazing. in this research, we used the proposed method of fao (1992) and for information layers crossing used in geographical information system (gis). in this research, sensitivity to erosion, water resources and forage production are three basic compone...

Abstract Pastoral systems face increasing pressure from competing global markets, food sector industrialization, and new policies such as Europe’s post-2020 Common Agriculture Policy. This threatens the use of extensive sheep-grazing in mountain areas low productivity but high natural value. Using information gathered at a long-term research setting mountainous area Basque Country (northern Spa...
