Effect of sward height and concentrate supplementation on forage dry matter intake, digestibility and grazing time of spring-calving beef cows
To establish the effect of sward height (SH) and concentrate supplementation on performance of grazing cattle, twenty-four cross bred Angus beef cow-calves were randomly assigned to two SH treatments (4--8 or 8--11 cm) with three supplement levels: 6.24, 3.12 or 0 kg/d. The study was conducted in …

Influence of forage characteristics on grazing behavior of weaned steers
… paddocks was determined on d 0, and forage mass, sward height and nutritive value were determined on d 0, 17 and 33. Behavior of steers was scanned every 5 min on d 24 and 25 from 0700 to 1900. The proportion of legumes was higher (P = 0.001) in A paddocks(37 %) compared to C paddocks (6%), while …

Monitoring biodiversity of San Francisco Peninsula grasslands using Lepidoptera as a bioindicator
… be highly managed and monitored to ensure varied sward height and heterogeneity of plant communities. Heavy grazing intensity (6.9 AMU ha<sup>-1</sup>)has large negative impacts to the environment. After a prescribed fire, plant biodiversity spikes and then declines with time while the …

Effekten av nematodinfektion på aktivitet och beteende hos förstagångsbetande lamm
… where the lambs grazed was a first-year pasture. Sward height was measured, and herbage samples were collected three times during the experiment. Herbage samples were analysed for nutritional and mineral content. The manual behavioural observations were made two days a week during five weeks. The …

Comparison of techniques for estimating pasture herbage mass and productive ground cover for Lakota prairie grass, Kentucky 31 endophyte free tall fescue, Kentucky 31 endophyte infected tall fescue and Quantum 542 tall fescue grazed by stocker steers
… replicate. Prior to harvesting, the canopy height within each quadrate was measured with a disc meter. In 2005, productive ground cover was assessed using visual evaluation techniques, point quadrat method, and digital imagery quantified with terrestrial remote sensing. Forages were …
