Campolina However, the dorsal surface of the neck should have a clear arch. This prominent crest accentuates the arch formed between the head and neck when the horse is flexed during riding. In a relaxed state, the balance of the face and neck from the side view can be evaluated by drawing a tangent from the points of maximal curvature. In the case of balanced conformation, the tangents should intersect roughly one inch in front of the ears (in the forward alert position). The weight range for Campolina stallions and geldings is and for mares. In well-bred, well-conditioned animals, the chest
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.
