Regional issues on animal genetic resources: trends, policies and networking in Europe

European countries are individually and in collaboration carrying out active work on animal genetic resources (AnGR). The region has a very good starting point for work on AnGR: The breed concept was developed in Europe; current European mainstream breeds are derived from local breeds and, in many species, have further formed the core of the international breeds; there has always been very active research in Europe on farm animal genetics and breeding, including sustainable utilization and management of variation. Since the 1970s and 1980s many European countries have been paying attention to local breeds and have saved many of them from total extinction. In quite a few countries, the conservation work has been supported by cryopreservation. In the Food and Agriculture Organization of the United Nations (FAO) coordinated process, Europe has actively contributed to assessing the State of the World's Animal Genetic Resources and will continue to implement the Global Plan of Action. There are now national action plans in most of the European countries. The European consumption of animal products has changed very little over recent decades. At the same time, production has become very intensive. Among other driving forces, the development of agriculture is steered by the EU policies. The last decade has seen new kind of thinking and measures directed towards an overall consideration of rural development. This has given room for the revitalization of many local breeds. The aim is to have schemes that promote the self-sustainability of local breeds. The EU also has a very ambitious research programme to support these aims while enhancing the overall sustainable production and management of biological resources. The European Regional Focal Point for Animal Genetic Resources (ERFP) is a common forum for the coordinators of European national programmes on AnGR. There are also many non-governmental organizations (NGOs) working in the animal sector. These NGOs and networks are most relevant to raising awareness about the importance of values of AnGR and in enhancing activities that contribute to conservation and sustainable use of AnGR

Eläintuotantoketjun tasapainoinen kehittäminen

Kotieläintuotanto on Suomen maatalouden tärkein alue. Luontaisimmat edellytykset siinä on maidontuotannolla. Tuotantoon kohdistuu elintarvikekaupan aiheuttamia kustannuspaineita. Niinpä tiloilla on lisättävä tehokkuutta ja yksikkökokoa jatkuvasti. Samalla täytyy huolehtia eläinten terveydestä ja hyvinvoinnista sekä ympäristön laadusta.vo

Breed differences of heritable behaviour traits in cats

Cat domestication and selective breeding have resulted in tens of breeds with major morphological differences. These breeds may also show distinctive behaviour differences; which, however, have been poorly studied. To improve the understanding of feline behaviour, we examined whether behavioural differences exist among cat breeds and whether behaviour is heritable. For these aims, we utilized our extensive health and behaviour questionnaire directed to cat owners and collected a survey data of 5726 cats. Firstly, for studying breed differences, we utilized logistic regression models with multiple environmental factors and discovered behaviour differences in 19 breeds and breed groups in ten different behaviour traits. Secondly, the studied cat breeds grouped into four clusters, with the Turkish Van and Angora cats alone forming one of them. These findings indicate that cat breeds have diverged not only morphologically but also behaviourally. Thirdly, we estimated heritability in three breeds and obtained moderate heritability estimates in seven studied traits, varying from 0.4 to 0.53, as well as phenotypic and genetic correlations for several trait pairs. Our results show that it is possible to partition the observed variation in behaviour traits into genetic and environmental components, and that substantial genetic variation exists within breed populations.Peer reviewe
