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 trypanosomiasis some breeds of cattle, notably the N'Dama – a West African "Bos taurus" breed. This contrasts with the susceptibility shown by East African "Bos indicus" cattle such as the zebu. Most trypanosomes develop in tsetse flies (Glossina spp.), in its biological vector, about one to a few weeks. When an infected tsetse fly bites an animal, the parasites are transmitted through its saliva. It can also be spread by fomites such as surgical instruments, needles, syringes. The most important vectors are thought to be horseflies (Tabanidae) and stable flies (Stomoxys spp.). The immune response of animals could be unable to
