João Pessoa: EMEPA-PB, 2009. 1 CD-ROM. 14 f.c2009  aThe scientific basis of selecting for overall reproduction or ewe productivity rather than selecting for a component trait of reproduction must be understood.

The assumption is that the rationale for genetic improvement of reproduction is to increase ewe productivity (profitability) per ewe exposed at breeding.  aEwes  aGenetic improvement  aProfitability  aReproduction  aSheep  aSmall ruminants
