<p>The aim of the present study was to identify the adaptability of Normandy cows raised in a loose system to the climatic and technological conditions and to compare their adaptability with already acclimatized Simmental cows in one farm in Southwestern Bulgaria. Total of 20 cows at same age (II – IV lactation) and same body weight (630-660 kg) from both breeds were classified into 2 groups (each having 10 cows) and subjected to skin thickness measurement, fibers total weight determination and fiber categorization during the winter and summer season. The results have shown that during the winter season, the Normandy breed had significantly higher skin thickness at the elbow compared to the Simmental breed, whereas no differences were observed in the skin thickness between both breeds either at the neck or at the middle of the last rib. During the summer season, the differences on the skin thickness compared to the Simmental breed were observed at the neck (p&lt;0.05), whilst at the elbow and at the middle of the last rib no differences were recorded (p>0.05). During the winter seasons, the coat of Normandy cows contained more soft fibers in comparison to the Simmentals cows. Furthermore, the changes in the observed parameters, influenced by climatic conditions showed similar pattern in both breeds. It can be concluded that the two breeds have emphasized their genetic potential and have a good adaptability to the temperate continental climate of the region.</p>

During the summer season, the differences on the skin thickness compared to the Simmental breed were observed at the neck (p0.05). During the winter seasons, the coat of Normandy cows contained more soft fibers in comparison to the Simmentals cows. Furthermore, the changes in the observed parameters, influenced by climatic conditions showed similar pattern in both breeds.
