Popis: The black or rarely roan Murgese is a mesomorph horse, mainly reared in Apulia, recently selected for the saddle. Thefirst official registry of Murgese was established in 1926. All the existing Murgese horses can be traced back to a smallnumber of founders (46 founder mares and 9 stallions). This work aims to monitor the genetic structure of the actualpopulation by analysing the available genealogical information from 2708 animals and a data-set containing 563 typingrecords of twelve microsatellites. Inbreeding coefficients were estimated for the whole sample and for the animals bornfrom 1992 to 1999. A total of 23 generations were found. The average inbreeding coefficient was 0.0165 for the last threegenerations, whereas inbreeding was below 2% in animals born in the 92-99 period. The contribution of founders wasunbalanced. The overall FIS coefficient estimation was 0.025 and suggests that mating is generally at random in the population.However, some statistics obtained from this study, i.e. the inbreeding coefficient higher than 0.015 in the 70 animalsof the 19th, 20th, and 21st generations, should induce breeders to more attention in planning mating.
