The effects of the ratio of grass silage to concentrates in the diet and restricted dry matter intake on the performance and carcass composition of beef cattle
R.W.J. Steen,D.J. Kilpatrick +1 more
TL;DR: Reducing energy intake by restricting DM intake or reducing the proportion of concentrates in the diet reduced the efficiency of carcass and lean gains, and for cattle reared on high-forage diets reducing slaughter weight is likely to be a more effective approach to reducing carcass fat content.

Can modelling enable us to understand the rôle of humans in landscape evolution
TL;DR: Simulations demonstrate the value of the agent-based approach in supporting the vulnerability of landform evolution to anthropic pressures, and demonstrate the limitations of existing models that ignore human and animal agency.

Behavioural responses to climatic demands of dairy heifers housed outdoors
TL;DR: The behaviour and location of each heifer were recorded by instant interval observations every 5 min between 0600 h and 2000 h during 23 observation days spread over the entire winter period, and the climate had significant effects on all the main activities and on the location of the heifers.
