Question: Polish Lowland Sheepdog and Brazilian Terrier are examples of breeds of which animal?

<P0-S0> Zelazna is a breed of sheep and is also known by "Zeleznienska". <P0-S1>  The Zelazna was developed at Warsaw Agricultural University. <P0-S2>  They belong to the Polish Lowland group and are found throughout Poland. <P0-S3>  They were developed from Polish Merino crossed with Leicester Longwool and Lowicz. <SEP> <P1-S0> The Brazilian Terrier, is a breed of dog developed in Brazil. <P1-S1>  It is one of several terriers probably descended from the combining of the Fox Terrier with other small breeds. <SEP> <P2-S0>  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. <P2-S1>  Cryogenically preserved specimens can be used to revive breeds that are endangered or extinct, for breed improvement, crossbreeding, research and development. <P2-S2> Cryoconservation of animal genetic resources is a strategy wherein samples of animal genetic materials are preserved cryogenically. <P2-S3>  Genetic materials that are typically cryogenically preserved include sperm, oocytes, embryos and somatic cells. <P2-S4>  Therefore, one of the main goals remains preserving the gene pool of local breeds that may be threatened. <P2-S5>  However, cryoconservation can be an expensive strategy and requires long term hygienic and economic commitment for germplasms to remain viable. <P2-S6>  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. <P2-S7>  Gene banks must maintain a precise database and make information and genetic resources accessible to properly facilitate cryoconservation. <P2-S8>  They must be able to facilitate germplasm collection, processing, freezing, and long term storage, all in a hygienic and organized manner. <P2-S9>  Cryoconservation can also face unique challenges based on the species, as some species have a reduced survival rate of frozen germplasm. <P2-S10>  Cryoconservation is an "ex situ" conservation strategy that often coexists alongside "in situ" conservation to protect and preserve livestock genetics. <P2-S11>  Cryogenic specimens of livestock genetic resources can be preserved and used for extended periods of time. <P2-S12>  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. <P2-S13>  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. <P2-S14>  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." <SEP> <P3-S0> The Polish Lowland Sheepdog (Polish: "Polski Owczarek Nizinny" , also PON), is a medium-sized, shaggy-coated, sheep dog breed native to Poland.
