Context_1 : 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. Context_2 : The German Shepherd (German: Deutscher Schäferhund , ] ) is a breed of medium to large-sized working dog that originated in Germany. The breed's officially recognized name is German Shepherd Dog in the English language (sometimes abbreviated as "GSD"). The breed is also known as the Alsatian in Britain and Ireland. The German Shepherd is a relatively new breed of dog, with their origin dating to 1899. As part of the Herding Group, German Shepherds are working dogs developed originally for herding sheep. Since that time however, because of their strength, intelligence, trainability, and obedience, German Shepherds around the world are often the preferred breed for many types of work, including disability assistance, search-and-rescue, police and military roles, and even acting. The German Shepherd is the second-most registered breed by the American Kennel Club and fourth-most registered breed by The Kennel Club in the United Kingdom. Context_3 : The Belgian Shepherd (also known as the Belgian Sheepdog or Chien de Berger Belge) is a breed of medium-to-large-sized herding dog. It originated in Belgium and is similar to other sheep herding dogs from that region, including the Dutch Shepherd, the German Shepherd, the Briard, and others. Four types have been identified by various registries as separate breeds or varieties: Groenendael, Laekenois, Tervuren, and Malinois. Context_4 : The King Shepherd is a dog breed developed from crossing German Shepherd Dog with Shiloh Shepherd and long-coated European lines of German Shepherd along with the Great Pyrenees in the 1990s. Context_5 : The old German herding dogs (German: "altdeutsche Hütehunde" ), including old German sheep-dogs or old German shepherd dogs (altdeutsche Schäferhunde ) are a group of traditional types of working, herding dogs from Germany. They are landraces consisting of working strains of dog, and some of them are the types from which the modern German Shepherd Dog was developed as a standardised breed. The landraces are not recognised by the Fédération Cynologique Internationale but some have their own standards, which are for working ability not appearance traits. Context_6 : The German Shepherd Dog in Word and Picture is a book first published in 1923. The book is a revised translation from German into English of Der deutsche Schäferhund in Wort und Bild which was written by Max von Stephanitz (the founder of the German Shepherd Dog breed) and first published in 1901 as a 72-page booklet (plus 24 pages of advertising). Der deutsche Schäferhund in Wort und Bild was subsequently expanded with later editions, and a complete makeover was published in 1921 with the sixth edition. A seventh edition of the German book was published in the same year as the first editions in English, 1923. Context_7 : Schutzhund (German for "protection dog") is a dog sport that was developed in Germany in the early 1900s as a breed suitability test for the German Shepherd breed. The test would determine if the dog displayed the appropriate traits and characteristics of a proper working German Shepherd. Today, it is used as a sport where many breeds other than German Shepherd Dogs can compete, but it is such a demanding test that few dogs can pass. Context_8 : Old German Shepherd Dog (German: "Altdeutscher Schäferhund" ) is a controversial name for the long-haired variation of the German Shepherd Dog (German: "Langstockhaariger Deutscher Schäferhund" ), which is not a separate breed recognized by the Fédération Cynologique Internationale. Nonetheless, there are efforts to establish this variety as a separate breed. Context_9 : "Panda German Shepherds" is a term coined for German Shepherd Dogs that exhibit a rare genetic mutation that causes white spotting the traditionally non-white marked breed of German Shepherd Dogs. This frequently debated color is often dismissed as a result of crossbreeding. However, new research has proven insightful of the true origin of this new marking. Context_10 : The skeletal remains of dogs from Nilgala cave and from Bellanbandi Palassa, dating from the Mesolithic era, about 4500 BC, suggest that Balangoda Man may have kept domestic dogs for driving game. The Sinhala Hound is similar in appearance to the Kadar Dog, the New Guinea singing dog and the Dingo. It has been suggested that these could all derive from a common domestic stock. fact_1 : The skeletal remains of dogs from Nilgala cave and from Bellanbandi Palassa, dating from the Mesolithic era, about 4500 BC, suggest that Balangoda Man may have kept domestic dogs for driving game. fact_2 : The German Shepherd (German: Deutscher Schäferhund , ] ) is a breed of medium to large-sized working dog that originated in Germany. Answer: dog
Output: Sinhala Hound and German Shepherd, are breeds of which animal?
