Taking into consideration the fact that the Romanian Black Spotted Breed has a significant part in the Moldavian cattle breed structure we thought it would be relevant to undertake studies and researches on its productive and longevity performances in one of the most representative farms (Dancu Iasi) that has dealt with its breeding and improvement for more than forty years.
Longevity research has been made on the whole population of the Romanian Black Spotted Breed in the Dancu-Iasi Farm considering all the cows that ended their productive life between 1995-2008. There is also important to underline the fact that the Dancu Farm has the most valuable biological material of the Romanian Black Spotted Breed as it was here that the first nucleus of the Frieze breed imported from Danmark in 1967 was introduced.
The longevity traits have been studied for a population of 999 cows as well as the precocity for all the primiparous selected between the years 2000-2008. The present study will show the synthetic scheme together with the experimental protocole, the research objective, the biologic material and the results obtained.
