Abstract. Title of the paper: Implications of health traits in breeding of dairy cattle Genetic improvement of health and fertility traits has gained major importance in dairy cattle breeding. Despite many physiological, immunological and biochemical traits proposed, the epidemiological approach provides an efficient tool to achieve genetic progress. Using datasets from Bavaria, Israel and Sweden heritabilities for liability of disease resistance were estimated. These estimates mainly were in the range of h2 = 1 to 4%. Reaction norm to fertility diseases estimated by using insemination parameters showed much higher heritability estimates of h2 = 10 to 19 %. These analyses demonstrate the large genetic variability in disease resistance, and that the genetic variance within breeds can be efficiently used for breeding highly resistant breeds. In order to make use of the genetic variance for disease resistance, a databank for health traits should be built up for German cattle breeds.

Dairy Cattle Breeding

SUMMARYThe state of the dairy herd in Kenya is described. The organization of the national dairy cattle breeding programme and the sire evaluation methods used are discussed in the light of the available data (1978–1988) and the relevant bibliography It is underlined that it was only possible to keep-up milk production - which matches consumption - by a dairy cattle population growth of 220% in the past decade, while the average yield remained unchanged around 3500 kg milk/lactation. The author underlines the need to improve livestock management practices and the genetic potential of dairy cows as the only means to face the needs of a growing human population.
