| Our aim was to map the performance of local (native) dairy cattle breeds in Austria, Switzerland, Poland, and Sweden with regard to production, fertility, longevity, and health-associated traits and to compare them with commercial (modern) breeds. For this purpose, we analyzed test-day records (July 1, 2011, to June 30, 2014) and treatment records (Austria, Sweden) of cows managed on organic farms. We performed country-wise comparisons of 123,415 lactations from Original Braunvieh (OB) and Grey Cattle (AL) with Braunvieh (BV; Brown Swiss blood >60%) in Switzerland; AL with BV (Brown Swiss blood >50%) in Austria; Polish Black and White (ZB), Polish Red and White (ZR), and Polish Red (RP) with Polish Holstein Friesian (PHF) in Poland; and Swedish Red... |

| Overall summary of main results, discussion and conclusions WP1 The aim in WP1 was to map the performance of local breeds compared to commercial dairy breeds on organic farms in Austria, Switzerland, Sweden, Poland and Germany with regard to health associated traits, fertility and production traits. In a study covering the whole population of the selected breeds, managed under organic conditions during the period 1.7.2011 to 30.6.2014, we found lower milk yields for local breeds. In general we found better fertility performance (less days open, shorter calving intervals, lower number of inseminations) for at least one of the local breeds involved in each country. We also detected lower proportions of milk records with somatic cell counts above 100.000... |
