To assess the potential for enhancing an existing stand of native perennial grasses on a California Coast Range Grassland site, we experimentally manipulated the seasonal timing and presence of grazing for 3 years (1994 through 1996) and of autumn burning for 2 years (1994 and 1995) and measured species cover for 6 years (1993 through 1998). We subjected the species matrix to classification (TW...

Control of ration quantity and composition is important in the management of horses with pituitary pars intermedia dysfunction (PPID) or equine metabolic syndrome (EMS) that exhibit obesity and/or hyperinsulinemia. In obesity, restriction of daily dry matter intake to 1.25% to 1.5% of current body weight will facilitate weight loss and improvement in insulin sensitivity in most horses, although...

Variabilities in the responses of several South African red and green macroalgae to direct grazing and the responses of one green alga to cues from grazers were tested. We used two feeding experiments: (1) testing the induced responses of three red and one green algae to direct grazing by mesograzers and (2) a multi-treatment experiment, in which the direct and indirect effects of one macrograz...

Fifty 3-month-old male Tan lambs (similar in body weight) were divided into 5 groups to investigate the effects of different restricted pasture grazing times and indoor supplementation on the productive performances and fatty acid composition of the intramuscular fat in growing lambs. The lambs grazed for different periods of time (12 h/d, 8 h/d, 4 h/d, 2 h/d, and 0 h) and received various amou...

In the pine forests of Mexico, disturbances are primarily due to cattle, horses, goat, and sheep grazing, particularly in communal grazing lands. The most evident low tree recruitment, invasive shrubs establishment, species composition changes, invasion weeds dispersed mainly by livestock. Sierra de Zapalinamé is a mountain range natural protected area northeast Mexico. We conducted current stu...

Parasitic infections are generally regarded as the most prevalent and important health problems of grazing ruminants in Australia, with losses associated with nematodes, and ectoparasites causing a combined annual loss of approximately a billion dollars (McLeod 1995). Liver fluke, although having a restricted distribution in temperate regions has been estimated to cost upwards of $100 million (...

Attention is drawn to several comparisons of the ARC feeding system with other systems. Recent Australian adaptations of ME standards for drought feeding of sheep and for cattle feeding are described. There is a need to adapt any feeding standards to the biology of the pastoral system. It is concluded that the Australia-wide adoption of ME based feeding standards would be helpful in promoting a...

This study was conducted at Eldebeibat area, in South Kordofan State, Sudan. The aim of this study was to assess the role of competition on rangelands’ utilization on occurrence of conflicts between land’s users in the semi-arid areas of Eldebeibat, Sudan. Two target questionnaires were designed to collect data from two groups of land users namely nomadic pastoralists and sedentary farmers that...

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...
