Invasive species threaten biodiversity and incur costs exceeding billions of US$. Eradication efforts, however, are nearly always unsuccessful. Throughout much of North America, land managers have used expensive, and ultimately ineffective, techniques to combat invasive Phragmites australis in marshes. Here, we reveal that Phragmites may potentially be controlled by employing an affordable meas...

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...

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...

Weaned Targhee x Hampshire lambs (average BW 27.6 kg) were used to determine the effects of concentrate feeding, forage grazing, or finishing on concentrate after grazing upon growth and carcass tissue accretion. Lambs were assigned randomly and balanced by weight and sex to five replicated treatments (12 lambs/treatment): all-concentrate in drylot (DL); rotational grazing alfalfa (ALF); rotati...

Grazing systems may alter botanical composition and productivity of grasslands through differential use in time, space, or intensity. Seven simulated grazing treatments were applied six years in eastern Montana, USA to determine effects on plant community composition and standing crop. Treatments were moderate stocking (28.8 AUD ha 1 year ) of cattle using 3-pasture summer rotation, season-long...

This work evaluated the productive and structural characteristics of BRS Zuri Quênia cultivars under rotational stocking management. The evaluations were divided into five periods according to rainfall regime (high, medium, low rainfall) during 16 months years 2016-2018. Pastures grazed when canopies intercepted 95% incident light stubbles corresponding 50% pre-grazing height. pre- post-grazing...
