The purpose of this study has been to evaluate the applicability of discriminant function analysis to determine gender dimorphism in Hucul horses, based on morphological indices obtained in different stages of life. A total of 243 horses, divided into six age groups, have been examined in its course. For each horse we have measured 12 metric traits, which were then used to calculate 13 biometric indices commonly used in horse breeding in Poland. These have become the basis for defining functions classifying the animals by gender in each of the six age groups. This study answers the question of what parameters play the greatest role in the course of shaping of body proportions of male and female horses in post-foetal development. The following indices have been found to significantly contribute in discriminant models: boniness, smaller trunk length, height at the croup, pelvis width and width of chest.

Native breeds of beef cattle in Britain have been superseded by imported breeds since the 1960s, but a changing market in the 1990s has begun to restore traditional values. The distinctive qualities of native breeds are becoming more relevant, and the White Park is a prime example of their importance. This paper makes a critical evaluation of several studies of White Park cattle that have been carried out, namely productivity in non-intensive systems of management, assessment of type and function by linear measurements, quality of product (meat), and value in crossing programmes. It concludes that breeds such as the White Park derive significant added value as a result of their native adaptability and the high quality of their beef, and that they benefit from a market driven by consumers rather than supermarkets. The use of different linear measurements is proposed, and the effective use of White Park bulls in crossing programmes is demonstrated.
