Body conformation of tuvinian short-fat-tailed ewes with different types of feeding behaviour

The article gives the data on the body conformation of Tuvinian short-fat-tailed sheep with different types of feeding behavior. Since the conformation is a breed characteristic, it was a criterion to assess animals. The research was carried out on Tuvinian short-fat-tailed ewes at the age of 3 years. The animals were divided into 3 groups on the basis of feeding behavior. The body conformation was studied from linear measurements of points. The physique index was calculated from the data on the measurements obtained. The animals were divided into groups according to the motor feeding response. This method assesses the individual behavior of sheep in a flock and characterizes their feeding, passive defensive and orienting response to the change of typical feeding procedure. The first type was termed as “strong fast gaining balanced type” (I group), the second one - “strong fast gaining unbalanced type” (II group), and the third one - “weak slow gaining type” (III group). The research revealed that the first group was characterized by a well-developed height measurements, chest girth and oblique length of the body. The ewes of the first type had a sound constitution with developed parts of the body, they were larger. The I type had higher massive indices than the others. The first group also had advantage in meat indices. The ewes of the III group had longer legs.
