Abstract

Transhumance is a ritual that happenes every year for ages, it liven up many traditions and recollections, also for tourist and cultural purposes. Nowadays this pratice is becomming more frequent all over the world as support for those areas which may otherwise be abandoned. One of the principal problems that this practice may face concerns the sostitution of the local autoctone breeds, which are the principal actors of this custom for ages, with Holstain and Brown cows with an high productitivity. With this study we tried to asses how dairy cows are able to deal with stressful situations such as a 50Km transhumance. We monitored 19 cows, 10 Holstain and 9 Brown, evaluating the quantities of their milk production and their metabolic parameters before and after the stress of a journey of 24 hours when coming back from alpine pasture. We try to evaluate possible changes in the status of animal welfare. Individual quantities of milk production and blood samples were collected both before departure and on arrival of the dairy cows as their own farm. The obtained data were statistically processed in order to assess any changes attributable to the practice of transhumance, the impact that breed could have and the production level of cows on this phenomenon. Results showed that some dairy cows have to forcedly abandon the path because of locomotion and metabolic problems. Milk production, in the most productivity animals, showed a sharp reduction and a metabolic situation to the arrival to their own farm such as a tipical chetosis in the lactation start. The two breeds monitored didn't show important variations in the assessed parameters but Holstain results must sensible to the fisical effort due to the transhumance.
