Title of the paper: <b>Genetic analysis of the population of Vorderwald cattle</b><br> The actual population of Vorderwald cattle, comprising 5452 animals has been analysed concerning the gene contribution, the generation interval and the degree of relationship and inbreeding with regard of five generations of ancestors. <br><br> About 84 % of the genes are originating from Vorderwald cattle. The genetic portions of other breeds have been contributed by Red Holsteins, Montbéliards and Ayrshires. The average generation interval parents–current animals is about 4.5 years. The mean relationship has been found out with 5.5 % within the bulls and 3.4 % within the cows. Accordingly the mean coefficient of inbreeding is higher within the bulls (2,7 %) than within the cows (2,4 %). Only 28.6 % of the bulls and 36.6 % of the cows are not inbred. With 0.9 % the increase of inbreeding in the last generation is of alarming proportions; that’s why a carefully directed program of mating has to be recommended.
