Congruence between selection on breeding values and farmers’ selection criteria in sheep breeding under conventional nucleus breeding schemes

open access: yesAnimal, 2011
Designing breeding schemes suitable for smallholder livestock production systems in developing regions has hitherto been a challenge. The suggested schemes either do not address farmers’ breeding goals (centralized station-based nucleus schemes) or yield

Economic values in broiler breeding

open access: yesPoultry Science, 1998
The objectives of this study were to derive economic values in broiler breeding and to determine their relationship with production circumstances. Economic values were derived using a deterministic economic model based on profit equations with a fixed amount of broiler meat output of the production system.
