Abstract
1. Recent developments in cattle, pig, sheep and horse breeding - a review Alena Svitáková, Jitka Schmidová, Petr Pešek, Alexandra Novotná Acta Veterinaria Brno CrossRef
Highlights
The results document the importance of including pre-weaning information for genetic prediction of the breeding value of beef bulls at performance test stations
The moderate genetic correlation between pre-weaning growth and growth in the test stations indicates that these traits share most of their genetic influences, they are not necessarily the same traits
The value of the direct permanent environment correlations showed that the bulls compensated in their growth during the test
Summary
Growth is a cumulative trait in which weight gain at a given moment is influenced by the history of the animal. It was demonstrated in several studies that the herd-of-origin effect was closely related to the growth ability of bulls (Přibylová et al, 2004; Schenkel et al, 2004; Nephawe et al, 2006). This may be because of the possibility that environmental conditions and herd management cause variability in baseline weights that, in turn, influence average daily weight gains during the study.
