Question: Drentse Patrijshond and Weimaraner are both breeds of what animal?
Context: 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. The Weimaraner ( ) is a large dog that was originally bred for hunting in the early 19th century.  Early Weimaraners were used by royalty for hunting large game such as boar, bear, and deer.  As the popularity of large game hunting began to decline, Weimaraners were used for hunting smaller animals like fowl, rabbits, and foxes. A designer crossbreed or designer breed is a crossbred animal that has purebred parents, usually registered with a breed registry, but from two different breeds.  These animals are the result of a deliberate decision to create a specific crossbred animal.  Less often, the animal may have more than two pure breeds in its ancestry, but unlike a mutt or a mongrel, its entire pedigree is known to descend from specific known animals.  While the term is best-known when applied to certain dog crossbreeds, other animals such as cattle, horses, birds and cats may also be bred in this fashion.  Some crossbred breeders start a freestanding breed registry to record designer crossbreds, other crossbreds may be included in an "appendix" to an existing purebred registry.  either form of registration may be the first step in recording and tracking pedigrees in order to develop a new breed. The Drentsche Patrijshond is a versatile spaniel-type hunting dog from the Dutch province of Drenthe.  Called the Dutch Partridge Dog (or "Drent" for Drenthe) in English, approximately 5,000 dogs are registered with the breed club in the Netherlands, and breed clubs operate in Belgium, Denmark, Scandinavia and North America.  The Drentsche Patrijshond bears some resemblance to both spaniel and setter types of dog.  An excellent pointer and retriever, this dog is often used to hunt fowl and adapts equally well to the field or marshes. The Tamworth is a breed of domestic pig originating in Tamworth, United Kingdom, with input from Irish pigs.  It is among the oldest of pig breeds, but as with many older breeds of livestock, it is not well suited to modern production methods and is listed as "Threatened" in the United States and "Vulnerable" in the UK by the Rare Breeds Survival Trust, as fewer than 300 registered breeding females remain.  This animal is of ginger to red colouration and is thought to have descended from wild boars, via native pig stock of Europe.  Principal populations today are in the United Kingdom, Australia, the United States, New Zealand, and Canada.  Alternative names for this animal are Sandy Back, and Tam. A breed group is a categorization of related breeds of animal by an overseer organization, used to organize the showing of animals.  In dogs, kennel clubs define the "Breed Groups" and decide which dog breeds are to be included in each breed group.  The Fédération Cynologique Internationale breed groups are used to organize dogs for international competition.  Breed groups often have the names of, and are loosely based on, ancestral dog types of modern dog breeds. This is a list of goat breeds.  There are many recognized breeds of domestic goat "(Capra aegagrus hircus)".  Goat breeds (especially dairy goats) are some of the oldest defined animal breeds for which breed standards and production records have been kept.  Selective breeding of goats generally focuses on improving production of fiber, meat, dairy products or goatskin.  Breeds are generally classified based on their primary use, though there are several breeds which are considered dual- or multi-purpose goats, so there is some crossover between lists. In modern agriculture, a rare breed is a breed of poultry or livestock that has a very small breeding population, usually from a few hundred to a few thousand.  Because of their small numbers, rare breeds may have a threatened conservation status, and they may be protected under regional laws.  Many countries have organizations devoted to the protection and promotion of rare breeds, for which they each have their own definition.  In botany and horticulture, the parallel to rare animal breeds are heirloom plants, which are rare cultivars. Doonies Rare Breeds Farm, Aberdeen, has one of Scotland's largest collections of rare and endangered farm animal breeds.  The farm is nationally recognised as a breeding centre for rare breeds.  There are 23 rare animal breeds on the farm. Some animal species and breeds once existed on the Isle of Man but are now extinct.  Some plant species have also been included at the end of this article.  There are no known specimens of the following breeds of dog, cattle, pig, horse and sheep.  Today only the Manx cat, Manx Loaghtan, Manx robber fly, Isle of Man cabbage and Manx marvel tomato exist as native breeds / types of the Isle of Man.
