Conformation is defined as the form or outline of an animal and is sometimes expanded to include a relationship of form to function. In the course ofa studentproject,25 traits were measured in each of 20 Thoroughbreds as 3-year-olds in training. "Winners" were three year olds who had won a listed race in 1990 as two year olds. "Others" were three year olds who had raced but not won in listed races in 1990 as two year olds. Twelve of these Waits were evaluated using a linear assessment scoring system; 13 traits were measured using a steel tape, vernier calipers or an improvised compass. This short communication confines itself to two measured waits, intermandibular width and cannon bone length. 相似文献

A total of 175 metapodials (MP) of Pleistocene and early Holocene bison (Bison priscus Boj.) from the vast area of northeast Russia were studied. MP were attributed to males and females both visually and statistically. Data on the withers height of bison from northeast Russia are provided. Stress markers were recorded, including so‐called “buttresses.” With rare exceptions, stress markers were not of a pathological nature. The origin and development of the buttresses are age‐related; their prevalence in bison females can be considered as the response to an increased load during pregnancy. Changes in the periosteum, found in males, are related to their greater activity. Buttresses are also well developed on metatarsals of the red deer and the elk; they are less developed in reindeer and not found in giant deer. A relationship among stress markers, locomotion and the environment is established. Possible peculiarities of the Rauchua River bison locomotion are discussed. 相似文献
