Gastrointestinal nematodes (GIN) constitute a problem in many sheep production systems, including those in Uruguay, causing reduced productivity and increased expenses. The main strategy to control GIN has consisted of the use of anthelmintics. Howev

Summary Breeding objectives were derived for pasture-fed Uruguayan beef cattle production systems, based on multi-purpose breeds. The traits in the breeding objective were weaning rate, calving ease (direct and maternal), sale weight (offspring and c

To satisfy increasing demands for fish as food, progress must occur towards greater aquaculture productivity whilst retaining the wild and farmed genetic resources that underpin global fish production. We review the main selection methods that have b

Summary Calving success (CS), days to calving (DC), birth weight (BW) and calving ease (CE) were studied in a mixed breed (Hereford, Jersey × Hereford and Simmental × Hereford) beef cattle herd. DC was not normally distributed and a number of trans

Summary The relative merits of calving rate (CR) and calving day (CD) as reproduction traits were examined in the context of a comprehensive breeding objective for beef cattle. It is shown that some criticsms made of CD are not justified. Reproductiv
