Campolina ears are evenly placed when viewed from the front of the horse and not extend vertically more than three times the width of the eye when measured across the inner pinnae. The pinnae should close to a clean tip at the top of each ear. Eyes should be expressive. In addition to the prominent curvature of the profile, the shape of the crest is also an important feature of the Campolina silhouette. In the relaxed forward pose, the ventral line of the neck from the caudal most point of the cheek to the top of the chest is quite straight.
Cryoconservation of animal genetic resources area, making the process of collecting germplasms easier and more efficient. The species and breeds of animals housed should be considered while planning the facility; facilities should be big enough to meet animal welfare standards, yet small enough to reduce human contact and increase ease of handling while reducing stress of the animal. As the process of collecting germplasm may take several days, the animal may become stressed causing a lower quality of genetic material to be obtained. Thus, training the animal to become familiar with the process is key. Holding facilities for animals may also serve as a quarantine.
