Question: Both the Ca de Bou and the Puli are breeds of what type of animal?

 The tight curls of the coat appear similar to dreadlocks. The Puli is a small-medium breed of Hungarian herding and livestock guarding dog known for its long, corded coat.  A similar-looking, but much larger breed – also Hungarian – is the Komondor. <SEP> In animal grooming, cording is a technique in which dog coats are separated patiently into dreadlocks for coat care or presentation purposes.  Some dog breeds that are often corded are the Puli and the Komondor.  The Havanese and Poodle are also occasionally corded for showing. <SEP> Cryoconservation of animal genetic resources is a strategy wherein samples of animal genetic materials are preserved cryogenically.  Animal genetic resources, as defined by the Food and Agriculture Organization of the United Nations, are "those animal species that are used, or may be used, for the production of food and agriculture, and the populations within each of them.  These populations within each species can be classified as wild and feral populations, landraces and primary populations, standardised breeds, selected lines, varieties, strains and any conserved genetic material; all of which are currently categorized as Breeds."  Genetic materials that are typically cryogenically preserved include sperm, oocytes, embryos and somatic cells.  Cryogenic facilities are called gene banks and can vary greatly in size usually according to the economic resources available.  They must be able to facilitate germplasm collection, processing, freezing, and long term storage, all in a hygienic and organized manner.  Gene banks must maintain a precise database and make information and genetic resources accessible to properly facilitate cryoconservation.  Cryoconservation is an "ex situ" conservation strategy that often coexists alongside "in situ" conservation to protect and preserve livestock genetics.  Cryoconservation of livestock genetic resources is primarily done in order to preserve the genetics of populations of interest, such as indigenous breeds, also known as local or minor breeds.  Material may be stored because individuals shared specific genes and phenotypes that may be of value or have potential value for researchers or breeders.  Therefore, one of the main goals remains preserving the gene pool of local breeds that may be threatened.  Indigenous livestock genetics are commonly threatened by factors such as globalization, modernization, changes in production systems, inappropriate introduction of major breeds, genetic drift, inbreeding, crossbreeding, climate change, natural disasters, disease, cultural changes, and urbanization.  Indigenous livestock are critical to sustainable agricultural development and food security, due to their: adaptation to environment and endemic diseases, indispensable part in local production systems, social and cultural significance, and importance to local rural economies.  The genetic resources of minor breeds have value to the local farmers, consumers of the products, private companies and investors interested in crossbreeding, breed associations, governments, those conducting research and development, and non-governmental organizations.  Therefore, efforts have been made by national governments and non-governmental organizations, such as the Livestock Conservancy, to encourage conservation of livestock genetics through cryoconservation, as well as through other "ex situ" and "in situ" strategies.  Cryogenic specimens of livestock genetic resources can be preserved and used for extended periods of time.  This advantage makes cryoconservation beneficial particularly for threatened breeds who have low breed populations.  Cryogenically preserved specimens can be used to revive breeds that are endangered or extinct, for breed improvement, crossbreeding, research and development.  However, cryoconservation can be an expensive strategy and requires long term hygienic and economic commitment for germplasms to remain viable.  Cryoconservation can also face unique challenges based on the species, as some species have a reduced survival rate of frozen germplasm. <SEP>  The difference between the sexes is in the head, the circumference is greater in dogs than in bitches.  The Perro de Presa Mallorquin was almost extinct after World War II, and the few remaining dogs were crossed with Majorca Shepherd Dog, Bulldog and perhaps Alano Espanol.  While extant specimens are all crossbred, the population as a whole retains standardized breed recognition in two kennel clubs, Fédération Cynologique Internationale, and United Kennel Club (using the FCI standard). Ca de Bou or Perro de Presa Mallorquin is a medium-to-large sized molossian-type breed of dog, with a strong, powerful, elongated build.
