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.
Animal genetic resources for food and agriculture assessments of livestock biodiversity: "The State of the World's Animal Genetic Resources for Food and Agriculture" (2007) and "The Second Report on the State of the World's Animal Genetic Resources for Food and Agriculture" (2015). Although many diverse species and breeds of animals are currently available for food and agricultural production, there is more work to be done on classifying their risk of extinction: in 2014, 17% of the world's farm animal breeds are at risk of extinction and 58% are of unknown risk status, meaning that the problem may be underestimated. The world's pool of animal genetic resources is
