Sažetak
Autochthonous Croatian cattle breeds belong to groups of endangered European cattle breeds. Genetic diversity is essential for preservation of adaptive potential of populations and improvement of production potential in further times. Monitoring of genetic diversity is the basis for effective conservation programmes. Pedigree analysis is useful tool in management of conservation strategy. In the work presented here, we investigate pedigree information of autochthonous cattle breeds in order to get insight in population structure and management of the genetic variability. In analysis were included 3017 records for Istrian cattle, 578 records for Slavonian-syrmian podolian cattle and 898 records for Busha, undertaken from the Herd Book in period from 1994 to 2009. The positive population trends are observable in increased number of animals per breeds and frequent calving recoreded in Herd Book, with stagnation in period from 2002 to 2004. High coefficient of inbreeding level and specific relationship with high average relatedness coefficient in population of Istrian cattle indicates the necessity of changing the breeding management. The main reason is utilisation of sires which are usually born in the same or related herd and the interchange of animals with other herds isn’t frequent. In population of Slavonian-syrmian podlolian cattle observed bottleneck and small number of founder suggest on necessity in redesign of mating scheme. Share of the high inbreed animals in population of Istrian and Slavonian-syrmian podolian cattle is relatively high. The lowest inbreeding and lowest average relatedness coefficient are found in Busha population. The obtained information will be useful to implement a conservation program in the Croatian autochthonous endangered cattle breeds.
