Campolina head. This conformation has been difficult to achieve in many animals, with many horses having the appearance of a short neck due to the curvature of the crest. The back of the Campolina should be a bit "long". When evaluating the animal's side profile, special attention should be paid to overall anatomical balance, which in this breed can err in overdevelopment of either the withers or the croup. Unbalanced horses tend to produce a rough ride and are referred to as having a "hard" gait. Specifically, the withers should be well-developed but not appear exaggerated or considerably higher than the
Animal genetic resources for food and agriculture sustainability of a breed and therefore to the potential for successful conservation activities." The Pantaneiro cattle of Brazil are only one example of many at risk of extinction. Despite the importance of animal genetic resources, their diversity has been continually decreasing over time. "Factors as causes of genetic erosion: One of the greatest threats to livestock diversity is pressure from large-scale commercial production systems to maintain only high-output breeds. Recent molecular studies have revealed that the diversity of today's indigenous livestock populations greatly exceeds that found in their commercial counterparts. Climate change and its impact on livestock is being studied.
