Evaluation of the Istrian cattle population structure by pedigree analysis

Local cattle breeds are an important part of genetic diversity, but due to globalization and industrialization of production, they are often marginalized. Istrian cattle is a local breed that almost became extinct three decades ago. Active measures have been taken to protect the Istrian cattle and the population has increased, gaining a new economic importance. The objective of this study was to analyze the status and trends of Istrian cattle using pedigree information. The population of Istrian cattle has stabilized trends in the number of animals and herds, although it requires constant monitoring. The levels of relatedness and inbreeding have plateaued (at 4.00% and 3.14%, respectively) and bottleneck in the population has not been observed. The mean number of equivalent generations is relatively low (2.99) and further systematic monitoring is important.
