root morphological and distribution responses of signal grass (brachiaria decumbens) to long-term cattle grazing were examined in a tropical pasture in malaysia. the treatments were no grazing by cattle and grazing at a moderate stocking density (2.7 animal unit/ha) under rotational grazing for 33 years. the method consists of taking soil core using a soil corer to a depth of 30 cm and extracti...

In northwestern Costa Rica, cattle are being used as a "management tool" to reduce the amount of combustible material, mainly dominated by Hyparrhenia rufa, an African grass. This project is being developed within Parque Nacional Palo Verde and Reserva Biológica Lomas Barbudal, both of which form part of the only remaining tropical dry forests in Mesoamerica. To determine the short-term effects...

BACKGROUND The aim of this study was to investigate possible cross-infection of Dichelobacter nodosus in Norwegian farms practising co-grazing of sheep and cattle. METHODS Thirteen farms practising co-grazing of sheep and cattle were included in this descriptive study: five farms with a history of severe ovine footrot (Group I) and eight farms with free-stall housing of cattle and signs of mi...

This study investigated effects of stocking rate on cattle performance, quality and quantity of corn residue, and impact of residue removal on grain yield for 5 yr at the University of Nebraska - Lincoln West Central Water Resources Field Laboratory near Brule, NE. Four removal treatments-1) no removal (control), 2) grazing at 2.5 animal unit month (AUM)/ha, 3) grazing at 5.0 AUM/ha, and 4) bal...

In 2010, the National Organic Program implemented a rule for the US stating that pasture must be a significant source of feed in organic ruminant systems. This article will focus on how the pasture rule has impacted the management, economics and nutritional value of products derived from organic ruminant systems and the interactions of grazing cattle with pasture forages and soils. The use of s...

A knowledge of parasitism in grazing animals is needed to properly understand and manage grazed ecosystems. This paper focuses on effects of gastrointestinal (GI) parasites in beef cattle. These parasites have both clinical and subclinical effects on animals. Cattle between the age of 5 and 15 months are affected most, and deworming typically increases weight gain in these animals by 0.1 to 0.2...

Recently, it has been proposed on theoretical grounds that carrion odor from flowers may not only attract pollinators, but also repel mammalian herbivores. Two grazing experiments involving 16 to 26 cattle heads per year, one for eight years (1982-1989) and the other for seven (1994-2000), in a region with no large carnivores that could influence cattle behavior, show that cattle avoid areas wh...

Dimander, S.-O. 2003. Epidemiology and Control of Gastrointestinal Nematodes in FirstSeason Grazing Cattle in Sweden. Doctoral thesis. ISSN 1401-6257, ISBN 91-576-6365-3. Gastrointestinal nematode parasites of first-season grazing cattle (FSGC) are ubiquitous and practically not feasible to eradicate. Heavy infections result in clinical parasitic gastroenteritis (PGE) characterized by diarrhoea...

The creation of improved areas is one way of increasing the productivity of livestock on Cantabrian heathland (NW Spain), a habitat that is frequently located in less favourable mountainous areas where the development of sustainable husbandry is limited. The effect of this on the biodiversity of heathland is unclear and likely to depend on several factors, such as the grazing regime. In order t...

Abstract This study determines which factors are associated with the use of rotational grazing and frequency Tennessee producers rotate cattle during summer months. Survey data were used to estimate an ordered response model sample selection. Most respondents grazing, most frequent schedule was rotating one two times per month. Factors including labor, capital, knowledge, water availability inf...
