The aim of the Diploma thesis was to monitor and evaluate selected influences on the weight of lambs at their birth. There were used basic breeding records of 604 lambs of both sexes in the breed of Wallachian sheep from the farm Ing. Jan Vejčík for the analysis. Birth weights were evaluated according to sex, litter frequency, litter order, paternal line and the year of birth. The results of the comparison brought the following findings. The influence of the father on the live weight of the lambs at birth was confirmed by the F test based on the significance level (p < 0.05 to 0.01) as statistically significant to almost highly significant. Comparing the average weight of lambs at birth by father´s line, the birth weight of lambs of the VALVEJ line clearly prevails. Moderate differences were shown between the effects of the frequency and order of litter, the other in terms of importance was the influence of the year of birth of lambs. The effect of sex of live-born lambs was statistically insignificant.

There are more details about genetic origins of farm animals with focus on horse, namely Old Kladruber horses as a Czech cultural monument. This breed is illustrative living example how to use genetic information for breeding and for conservation of the species.
