The objective of this study was to estimate genetic parameters for the results of classifying of carcass traits by the SEUROP method in beef cattle in the Czech Republic using linear and linear-threshold models. Genetic parameters were calculated and

Three selection indexes were constructed for bulls of beef cattle: IM for terminal crossing (in dairy herds), IZ for the selection of foundation sires for beef herd and IS for the selection of bulls for beef herd. Each index was constructed in five v

Genetic and economic responses to genetic gain were evaluated for these breeding arrangements: single use of bulls under testing; single and repeated use of proved bulls for two years and for three years (in combination with selection intensity 1%, 5

The type was evaluated in 5 424 young animals of twelve beef breeds. Ten type traits were evaluated: height at sacrum (HS), body length (BL), live weight (LW), front chest width (CW), chest depth (CD), pelvis (P), shoulder muscling (SM), back musclin

Sub-indexes were constructed for bulls of the Holstein breed according to groups of production traits - production index for milk (IPH), sub-indexes for reproduction (IRH), longevity (IDH), health resistance (IOH) and fitness (IFH). Every index for s

Complex selection indexes are proposed for bulls of Holstein cattle in the Czech Republic. Partial breeding values for milk performance, fertility and body conformation are combined in the index. Conformation is expressed either by linear classificat

Disorders of sexual development (DSD) refers to a group of diseases that links the mismatch between an individual’s genetic and gonadal development and its phenotype. Ovotesticular DSD (true hermaphroditism) is one such disease, in which both male
