The most important new biotechnologies, currently used in animal husbandry, are dealing with a role of genomes in physiological background of economically important traits in livestock, multiple ovulation and embryo transfer and in vitro embryo production. Cloning by nuclear transfer and transgenesis are still in development and they are mainly applied for experimental purposes with the prospect of a more widespread practical implementation in future. It appears that the introduction of new biotechnologies in animal husbandry should be accompanied by scientifically valid and systematic studies in the favour of animal welfare, conservation of genetic resources, environment interactions and efficiency of processing and marketing of livestock products. This direction enables to enhance the consumer safety concerning the use of livestock-derived food.
