In this thesis, the body dimensions of twenty Lapland cows in the cowshed of the Rural Entrepreneurship Center located in Loue, Tervola were measured. The body measurement points were the same points that were measured and recorded in the pedigrees a hundred years ago. The ten body measurements were withers height, chest height, chest width, pelvis width at the outer and the corners of the hip bones and the inner corners of the back bones, chest circumference behind the shoulder blades, rear body circumference in the front of the hip bones, body length from the front of the shoulder blades to the corners of the backbones, and body length. An Excel table prepared by Jaana Juvani for her thesis at Oulu University of Applied Sciences in 2014 from the chapters of old genealogy books was available for the measurement results of a hundred years ago. In this work, comparisons were made of the numbers measured in Loue. Based on observational data, it was found that the size of current Lapland cows has increased in every part of the body. Chest width (37%) and pelvis width on the outside of the hip bones (18%) have grown the most. The withers height of Lapland cows has increased in a hundred years by about eleven centimeters and in percentage terms by more than ten percent. In a hundred years, the chest height measurement had only grown by barely a centimeter. It is hoped that the measurements of this thesis will be the beginning of a history of measurements, in which case we would continue to regularly receive data on how the size of the Lapland cow changes over time. The body dimensions of the cow are affected by e.g. level of feeding, production season, pregnancy, respite period and season, so measurements can be recommended to be done often. From the point of view of historical research of domestic animals, collecting long-term measurement data is important. It is especially important for northern Finnish cattle, also known as the Lapland cow. It is the only Finnish mountain cattle breed. The breed was threatened with extinction for a long time. The breed has shown that it can get along with scarce conditions. If the earth's conditions at the height of Finland become critical, we have a breed that can adapt to new conditions due to its genetic inheritance. The work also includes an overview of articles published in the 1930s by the newspapers Lapin Kansa and Rovaniemi, as well as the newspapers Kaleva and Pohjolan Sanomat, about cattle breeding and especially the northern Finnish cattle.
