In recent years, dairy farmers have observed a substantial decrease in cows’ survival, with a direct negative consequence on the profitability. Shorter lifespan raises questions about animal welfare and farming conditions at which cows are exposed to. However, the length of productive life depends also on voluntary culling due to low productivity and, in dual-purpose breed, to low price of carcasses (meat). The general aim of the thesis was to investigate the genetic and phenotypic relationship of functional longevity with morphological features like muscularity and body condition score (BCS) and productive traits within Italian Simmental dual-purpose dairy cattle raised in Emilia-Romagna herds.
