Breeding programs for livestock require economic weights for traits that reflect the most profitable animal in a given production system. Economic weights are commonly based on average conditions. In pasture based livestock production systems the cost of feed is an important profit driver, but...

On the basis of a Ginzburg-Landau-type description we consider the growth of droplets from a metastable state in binary systems with a non-conserved order parameter coupled to a diffusive non-ordering field. A simple example of such a system is a uniaxial antiferromagnet with energy conservation.
