Changes in body components of autumn-calving Holstein-Friesian cows over the first 29 weeks of lactation
Changes in body composition of 54, second to fourth parity, autumn-calving Holstein-Friesian dairy cows offered grass silage ad libitum and 3(L), 6(M) or 9(H) kg concentrate dry matter per day wereExpand
Effect of sward surface height on intake and grazing behaviour by lactating Holstein Friesian cows
The results show that SSH can significantly influence intake rate, but, while the cow's only effective strategy to compensate for any reduction in intake rate is to increase grazing time, this may be limited by the requirement for ruminating and non-grazing, non-ruminating activities. Expand
Effect of time of day on grazing behaviour by lactating dairy cows
Although time of day did not affect GJM rate, it had a quadratic effect on the proportion of GJMs represented by biting and non-biting jaw movements, resulting in a significant effect on bite rate. Expand
The sustainable development of grassland-livestock systems on the Tibetan plateau: problems, strategies and prospects
The Tibetan plateau is the source of most of the major rivers of Asia and has a huge impact on the livelihoods of the population, who have for centuries engaged in traditional herding practices.Expand
The effect of physiological state (lactating or dry) and sward surface height on grazing behaviour and intake by dairy cows
Abstract The effect of physiological state lactating vs. non-lactating (dry) on grazing behaviour and herbage intake by Holstein-Friesian cows was examined on grass pastures maintained at 5, 7 or 9Expand
Impact of eprinomectin on grazing behaviour and performance in dairy cattle with sub-clinical gastrointestinal nematode infections under continuous stocking management.
Forty spring-calving cows and heifers were allowed to acquire infection with gastrointestinal (GI) nematodes naturally during grazing in order to evaluate the effect of GI nematode on grazing behaviour, milk production, body condition score and live weight. Expand
Grassland management with emphasis on grazing behaviour
Investigations into the behavioural responses by ruminants to differences in their grazing environment have led to improved understanding of the grazing process, and evidence is presented of the implications for improving current management practices on farm, or novel approaches to improving the utilization of traditional pasture species.

Influence of sward height on diet selection by horses
Investigation of the influence of sward height on diet selection by horses grazing perennial rye-grass swards found horses resided significantly longer on patches with long grass than on those with short grass. Expand
The effect of ewe body condition at lambing on the performance of ewes and their lambs at pasture.
Herbage intakes, milk yields and lamb growth rates were all significantly higher at the low stocking density than at the high stocking density, and the daily growth rates of the lambs during the first 8 weeks and the overall live-weight gains were significantly higher for lambs suckling by fat ewes than for those suckled by thin eWes.
