Rabbits’ participation in Animal-Assisted Interventions (AAIs) is growing. It is highly important to ensure the well-being of the animals in AAIs. Whereas the needs and the advantages of people involved in AAI are becoming more and more evident, the needs of animals are not clearly defined, therefore, it is a great field of inquiry. Animals who are used for AAI need to be transported regularly, which itself might be a source of stress. (2) Methods: the stress of rabbits—caused by transportation—was measured in a non-invasive way: cortisol levels were determined from feces, based on their breakdown products. Eighteen animals were involved in the study. Rabbits experienced a 30 min transportation every second day for two weeks (altogether six times) while 126 samples were collected. (3) Results: rabbits could handle the transportation procedure the first time but subsequently the stress hormone metabolites in feces samples increased regardless of the offered treatments (hay, carrot and apple) during the carriage. (4) Conclusions: those owners who use rabbits for Animal-Assisted Interventions need to take into account that transportation itself is a stressful experience for the animals.}, keywords = {RABBITS; CORTISOL; TRANSPORTATION; animal-assisted interventions; AAI; stress}, year = {2024}, eissn = {2076-2615}, orcid-numbers = {Nagy, István/0000-0003-0247-6638; Molnár, Marcell/0000-0001-9573-7993} } @article{MTMT:34684720, title = {Population Subdivision and Migration Assessment of Mangalica Pig Breeds Based on Pedigree Analysis}, url = {https://m2.mtmt.hu/api/publication/34684720}, author = {Nguyen, Anh Thi and Kövér, György and Tóth, Péter and Curik, Ino and Bokor, Árpád and Nagy, István}, doi = {10.3390/ani14040653}, journal-iso = {ANIMALS-BASEL}, journal = {ANIMALS}, volume = {14}, unique-id = {34684720}, abstract = {In conserving the genetic diversity of domestic animal breeds, strategies that emphasise between-breed diversity may not be optimal, as they neglect within-breed variation. The aim of the present study was to assess the extent of population subdivision in three Mangalica pig breeds and the contribution of migration to their substructure. Wright’s FST coefficient was calculated based on genealogical data with breeding animals born between 1981 and 2023, with three colour variants (Blonde, Swallow-Belly and Red). These Wright’s FST coefficients were analysed using multidimensional scaling to reveal the population substructure. The average FST coefficient was 0.04 for the Blonde breed and 0.047 for the Swallow-Belly and Red Mangalica breeds, while these parameters were lower in the active herds at 0.03 and 0.04, respectively. The migration of individuals between herds was 61.63% for the Blonde breed and 75.53% and 63.64% for the Swallow-Belly and Red Magalica breeds, respectively. No population substructure was observed in any of the Mangalica breeds, which can be explained by the extensive migration between herds.}, keywords = {MIGRATION; pedigree analysis; Mangalica; Population subdivision; Wright’s FST coefficient}, year = {2024}, eissn = {2076-2615}, orcid-numbers = {Curik, Ino/0000-0001-7090-1654; Nagy, István/0000-0003-0247-6638} } @article{MTMT:34683041, title = {Housing European Ground Squirrels (Spermophilus citellus) for an Ex Situ Conservation Program}, url = {https://m2.mtmt.hu/api/publication/34683041}, author = {Bárdos, Boróka and Altbäcker, Vilmos and Török, Henrietta Kinga and Nagy, István}, doi = {10.3390/mps7020018}, journal-iso = {METHODS PROTOC}, journal = {METHODS AND PROTOCOLS}, volume = {7}, unique-id = {34683041}, abstract = {European ground squirrel (Spermophilus citellus) populations have declined precipitously over the last 70 years. Its protection cannot be ensured solely by protecting its habitat; it is also necessary to protect the animals ex situ. In our study, within a European ground squirrel species protection program, we examined two elements of indoor housing technology. Knowledge of the animals’ needs is essential for captive housing and breeding success, so in our tests, the animals could freely choose both nest-building materials and feed. In the nest material preference test, the animals could choose from three materials with different structures: paper, Lignocel and hay. In the feed preference test, the animals could also choose from three types of feed: commercial rabbit feed, complete rabbit feed and a natural feed mixture. The first two feeds were in granulated format, and the third was a grain feed mix. Among the nesting materials, they preferred hay, which allowed them to build better-quality nests. Among the feeds, they preferred the grain feed mix, the composition closest to their natural feed, and it was the only one that contained animal protein. Our results contribute to the successful maintenance and breeding the European ground squirrel in captivity.}, keywords = {European ground squirrel; captive breeding; Feed preference; nest material preference}, year = {2024}, eissn = {2409-9279}, orcid-numbers = {Altbäcker, Vilmos/0000-0001-7592-1232; Nagy, István/0000-0003-0247-6638} } @article{MTMT:34450378, title = {Characterizing and Eliminating the Inbreeding Load}, url = {https://m2.mtmt.hu/api/publication/34450378}, author = {Nagy, István and Nguyen, Anh Thi}, doi = {10.3390/vetsci11010008}, journal-iso = {VET SCI}, journal = {VETERINARY SCIENCES}, volume = {11}, unique-id = {34450378}, issn = {2306-7381}, abstract = {The authors evaluated the relevant literature related to purging, which is the interaction between selection and inbreeding in which the population may eliminate its inbreeding load at least partially. According to the relevant literature, the inbreeding load and the process of purging were evaluated via pedigree methods based on ancestral inbreeding, the inbreeding–purging model, and expressed opportunity of purging, along with genomic methods. Most ancestral inbreeding-related studies were performed in zoos, where only a small proportion of the studied populations show signs of purging. The inbreeding–purging model was developed with Drosophila, and it was used to evaluate different zoo ungulates and Pannon white rabbits. Purging was detected in both studies. The expressed opportunity of purging was applied in Jersey cattle and Pannon white rabbits. In the Jersey cattle, it had an effect of 12.6% for fitness, while in the Pannon white rabbits, the inbreeding load was between 40% and 80% of its original value. The genomic studies also signalled purging, but they also made it clear that, contrary to the detected purging, the evaluated populations still suffered from inbreeding depression. Therefore, especially for domesticated animals, it can be concluded that deliberate inbreeding with the purpose of generating purging is not advocated.}, year = {2024}, orcid-numbers = {Nagy, István/0000-0003-0247-6638} } @misc{MTMT:34327860, title = {The Impact of Transportation to the Cortisol Level of Dwarf Rabbits Bred to Animal Assisted Interventions}, url = {https://m2.mtmt.hu/api/publication/34327860}, author = {Suba-Bokodi, Éva and Nagy, István and Molnár, Marcell}, unique-id = {34327860}, year = {2023}, orcid-numbers = {Nagy, István/0000-0003-0247-6638; Molnár, Marcell/0000-0001-9573-7993} } @{MTMT:34215322, title = {Classical, Ancestral, and New Inbreeding of X-Chromosome in Czech Local Dairy Goat Breed}, url = {https://m2.mtmt.hu/api/publication/34215322}, author = {Vostrý, Luboš and Vostrá-Vydrová, Hana and Shihabi, Mario and Hofmanová, Barbora and Kövér, György and Farkas, János and Nagy, István and Moravčíková, Nina and Kasarda, Radovan and Curik, Ino}, booktitle = {31st International Symposium.
