Possibility of early selection of Limousin young stock based on analysis of repeatedly measured body size parameters
Abstract
In beef cattle breeding, analysing body size parameters enables the evaluation of production-related correlations and growth dynamics. By assessing these traits at multiple time points, it becomes possible to identify early predictors of later development, supporting early selection decisions. In this study, the correlations between the data measured at weaning (230 days) and at 13–14 months of age (weight, withers height, tail height, length of back, shoulder width, hip width and pin width) were analysed. Data of bull calves kept for breeding and fattening at weaning ages were also compared. The results indicated a weaker correlation between body measurements taken at weaning age (rAVG= 0.581) than at 13–14 months of age (rAVG= 0.640, n = 817). Pin width showed very weak correlations in all cases (r = 0.293–0.930). The strongest positive correlation between the two measurement times was found for withers height (r = 0.618) and tail height (r = 0.631). The results of fattening bulls were compared with those of bull calves retained for breeding. Comparative analysis revealed that breeding bulls outperformed fattening bulls across all parameters except the overgrowth index and pin width. These findings suggest that selection decisions can be effectively based on measured traits alone. Overall, although Limousin calves exhibit variable growth rates, withers height and tail height can be regarded as pre-selection criteria for breeding programs.
