Feed Intake Specifications in Defining Breeding Objectives

SUMMARY Development of selection objectives for beef cattle requires tion of the available feed resources. In production systems \Ji th to li~eral quantities of harvested feeds of relatively high quality to improve economic eff iciency ~lill normally favor animals ~li th high potentials for the primary production traits.

Progress in ideotype breeding to increase rice yield potential

The ideotype approach has been used in breeding programs at the International Rice Research Institute (IRRI) and in China to improve rice yield potential. First-generation new plant type (NPT) lines developed from tropical japonica at IRRI did not yield well because of limited biomass production and poor grain filling. Progress has been made in second-generation NPT lines developed by crossing ...

Epidemic malaria and warmer temperatures in recent decades in an East African highland

Climate change impacts on malaria are typically assessed with scenarios for the long-term future. Here we focus instead on the recent past (1970-2003) to address whether warmer temperatures have already increased the incidence of malaria in a highland region of East Africa. Our analyses rely on a new coupled mosquito-human model of malaria, which we use to compare projected disease levels with ...
