Resumo: | This work was development in two experiments: evaluation of feed parameters of bullfrog, Lithobates catesbeianus (SHAW, 1802), sampled in natural environments and evaluation of gastric capacity, predation and time of passage of preys (tadpole and imago) in digestive system of bullfrog Lithobates catesbeianus (SHAW, 1802) maintained in captivity in different weights. The first experiment aimed to know the feed behavior of bullfogs in municipalities of Minas Gerais and São Paulo state (Brazil). There were sample 49 animals, they were frozen and taken to the Laboratory of Bullfrog Culture of Federal University of Viçosa. Subsequently, they were dissected and its gastric content was then studied. Each prey was indentified until its higher taxonomic level. The second experiment aimed evaluate gastric and predation capacity and the total time of passage of the prey (tadpole and imago of bullfrog) in digestive system. There were used 876 tadpoles in different stages of development (GOSNER, 1960) and 420 imagoes, using 710 bullfrogs feeding induced, with 5 weight imago classes: class 1, imagoes from 10.00 to 39.99 g; class 2, imagoes from 40.00 to 69.99 g; class 3, imagoes from 70.00 to 99.99 g; class 4, imagoes from 100.00 to 149.99 g; and class 5, from 150.00 to 199.99 g. Those animal in induced feeding past through a 48 h fasting before feeding and their prey, both tadpoles and imagoes, were case-hardened to determinate its weights and volume. In the imagoes, also it was verified the length between face and cloaca. It was verified that bullfrogs, when young, feed mainly insects and that they are more generalist when adult, with wild variety diet: insects, crustacean, anuran amphibian and snakes. Bullfrogs have a great development capacity in environment which they are introduced and it has a high chance of dissemination. The total feed passage time in digestive system is independent of the classes studied. The gastric capacity decreases as the total corporal weight increases. The total passage time of tadpole is slower than the imagoes. The bullfrog is an animal with a high impact on herpetofauna. |

O primeiro experimento visou conhecer o hábito alimentar da rã-touro em alguns Municípios do Estado de Minas Gerais e São Paulo. Em que foram coletados 49 animais, congelados individualmente e levados ao laboratório do Ranário Experimental da Universidade Federal de Viçosa, sendo posteriormente dissecados e averiguados os conteúdos gástricos dos animais, e cada presa identificada até seu menor nível taxonômico. O segundo experimento foi executado com objetivo de avaliar a capacidade gástrica, de predação e o tempo de passagem da presa (girino e imago de rã-touro) pelo aparelho gástrico de rã-touro. Foram utilizados 876 girinos em diferentes estágios de desenvolvimento (GOSNER, 1960) e 420 imagos de rã-touro, na alimentação induzida de 710 exemplares de rã-touro, com cinco classes de peso: classe 1, imagos de 10,00 a 39.99 gramas; classe 2, imagos de 40,00 a 69,99; classe 3, rãs de 70,00 a 99,99 gramas; classe 4, rãs de 100,00 a 149,99 gramas; e classe 5, rãs de 150,00 a 199,99 gramas. Os animais que submetidos à alimentação induzida foram mantidos em jejum por 48 horas antes da alimentação. E suas presas, os girinos e imagos em jejum, foram insensibilizados para verificar seu peso corpóreo e volume. Nos imagos também foi feita a medida do comprimento rosto cloacal (CRC). Verificou-se que a rã-touro quando jovem se alimenta principalmente de insetos, e quando adultos são mais generalistas, tendo uma dieta bem variada desde: insetos, crustáceos, anfíbios anuros e até ofídios. A rã-touro possui grande capacidade de se desenvolver nos ambientes onde foi introduzida e com alta chance de se disseminar na região; O tempo de passagem independe da classe de tamanho da rã-touro; A capacidade gástrica diminui com o aumento do peso corpóreo dos animais; O tempo de passagem do alimento no aparelho gástrico da rã-touro é menor, quando alimentadas com girino, e maior quando alimentadas com imagos; A rã-touro é um animal altamente impactante para a herpetofauna.application/pdfporUniversidade Federal de ViçosaMestrado em Biologia AnimalUFVBRBiologia e Manejo animalRã-touroDietasImpacto ambientalPredaçãoBullfrogDietEnvironmental impactPredationCNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIA::ZOOLOGIA APLICADACaracterísticas alimentares e potencial impactante da rã- touro Lithobates catesbeianus (SHAW,1802)Characteristics and potential impact of bullfrog Lithobates catesbeianus (SHAW,1802)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf832121https://locus.ufv.br//bitstream/123456789/2219/1/texto%20completo.pdf9fd87024079c38e3d2021a80d563b0e2MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain111764https://locus.ufv.br//bitstream/123456789/2219/2/texto%20completo.pdf.txt33998187a37a1f49ba45fc3d9c27025cMD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3576https://locus.ufv.br//bitstream/123456789/2219/3/texto%20completo.pdf.jpgb481c6057ef10bbaca101c1ae17b3b3aMD53123456789/22192016-04-08 23:01:56.227oai:locus.ufv.br:123456789/2219Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-09T02:01:56LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
