Information on the physiological ecology of grass-dominant pastures has made a substantial contribution to the development of practices that optimise the amount of feed harvested by grazing animals in temperate livestock systems. However, the contribution of ecophysiology is often under-stated, and the need for further research in this field is sometimes questioned. The challenge for ecophysiol...

Abstract The objective of this study was to evaluate the grazing behavior mature beef cows natural grassland in silvopastoral systems (SPS) comparison with pasture full sun (FS) during austral summer South America. A total fifty-five Braford crossbred multiparous suckled (352 ± 43 kg) were randomly assigned two treatments, replicates, a complete randomized design: SPS (n=28) and FS (n=27). Glob...

BACKGROUND: Previous studies showed differences in fatty acid (FA) and antioxidant profiles between organic and conventional milk. However, they did not (a) investigate seasonal differences, (b) include non-organic, lowinput systems or (c) compare individual carotenoids, stereoisomers of α-tocopherol or isomers of conjugated linoleic acid. This survey-based study compares milk from three produc...

A dynamic model for nematode parasites in lambs which links their adult parasite burden with liveweight gain was extended to investigate alternate grazing with cattle to provide relatively larval-free pasture for finishing lambs. Liveweight performance of weaned lambs was tracked fortnightly under rotational grazing using three cattle:sheep ratios, with three initial parasite burdens and two in...

We analyzed how three different dairy management systems –continuous grazing, confinement and management intensive grazingcompare across nine sustainability indicators set by the Dairy Stewardship Alliance. A self-assessment survey comprising animal husbandry, biodiversity, energy, community health, farm financials, nutrient, pest, water and soil management was assessed twice across the same fa...

By killing cattle and otherwise complicating management, the many species of larkspur (Delphinium spp.) present a serious, intractable, and complex challenge to livestock grazing management in the western United States. Among the many obstacles to improving our understanding of cattle-larkspur dynamics has been the difficulty of testing different grazing management strategies in the field, as t...

Government policies relating to red meat production take account of the carbon footprint, environmental impact, and contributions to human health and nutrition, biodiversity and food security. This paper reviews the impact of grazing on these parameters and their interactions, identifying those practices that best meet governments' strategic goals. The recent focus of research on livestock graz...
