Resumo: The present work has the purpose of evaluating the structure of a population of Morada Nova sheep breed from State of Ceará. Data were collected from the file to control the breeding of Sheep Improvement Project for the Morada Nova Breed white variety, of the Department of Animal Science in the period from 1970 to 1987 for records of 2,403 animals, (922 males and 1,481 females). The effective size (Ne), coefficient of consanguinity (F) and average relatedness coefficient (AR) individuals, effective size of founders and ancestors (fa and fe), generation interval (IEG), integrity of pedigrees and Wright’s F statistics have been estimated. We could observe the occurrence of loss of original genetic material and the intensive use of related animals among the sheep. The obtained generation interval average for males was satisfactory, although for females the averages had lower magnitudes. The estimated AR medium rates had few variations in population, except for the first five years of record. We could observe subdivision in population due to the more intense use of some breeding animals causing genetic isolation among flock. Therefore, we came to the conclusion that this flock was in a critical situation during the period of this study, and it needs a focused administration in preservation and conservation

Os dados foram provenientes do fichário de controle zootécnico do Projeto de Melhoramento de Ovinos da Raça Morada Nova variedade branca, do Departamento de Zootecnia, no período de 1970 a 1987, referentes a registros de 2403 animais, sendo 922 machos e 1481 fêmeas. Foram estimados o tamanho efetivo (Ne), coeficiente de consanguinidade (F) e parentesco médio (AR) dos indivíduos, tamanho efetivo de fundadores e de ancestrais (fa e fe), intervalo de gerações (IEG), integridade dos pedigrees e estatísticas F de Wright. Os resultados obtidos evidenciaram que houve ocorrência de perdas do material genético de origem e o uso intensivo de animais aparentados dentro do rebanho no período estudado. Para os machos, a média estimada do intervalo de geração foi satisfatória e, para as fêmeas, apresentou média inferior. Já, os valores médios estimados de AR sofreram pequenas variações na população, com exceção dos primeiros cinco anos de registro. Também, observou-se subdivisão na população, devido ao uso mais intenso de alguns reprodutores, proporcionando, assim, isolamento genético no rebanho. Portanto, concluiu-se que este rebanho de ovinos da raça Morada Nova variedade branca encontrava-se em estado crítico no período estudado, necessitando de gestão que possibilitasse a sua preservação e conservaçãoDiversidade genéticaOvinosConsanguinidadeEstrutura populacional de um rebanho morada nova variedade branca no estado do CearáPopulation structure of a flock new dwelling white variety in the state of the Cearáinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisporreponame:Repositório Institucional da Universidade Federal do Ceará (UFC)instname:Universidade Federal do Ceará (UFC)instacron:UFCinfo:eu-repo/semantics/openAccessORIGINAL2009_dis_dsrodrigues.pdf2009_dis_dsrodrigues.pdfapplication/pdf427309http://repositorio.ufc.br/bitstream/riufc/14340/1/2009_dis_dsrodrigues.pdfe9adf67ba3f756188bb23fbd88e8285fMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81786http://repositorio.ufc.br/bitstream/riufc/14340/2/license.txt8c4401d3d14722a7ca2d07c782a1aab3MD52riufc/143402020-05-13 16:11:55.619oai:repositorio.ufc.br:riufc/14340w4kgbmVjZXNzw6FyaW8gY29uY29yZGFyIGNvbSBhIGxpY2Vuw6dhIGRlIGRpc3RyaWJ1acOnw6NvIG7Do28tZXhjbHVzaXZhLAphbnRlcyBxdWUgbyBkb2N1bWVudG8gcG9zc2EgYXBhcmVjZXIgbm8gUmVwb3NpdMOzcmlvLiBQb3IgZmF2b3IsIGxlaWEgYQpsaWNlbsOnYSBhdGVudGFtZW50ZS4gQ2FzbyBuZWNlc3NpdGUgZGUgYWxndW0gZXNjbGFyZWNpbWVudG8gZW50cmUgZW0KY29udGF0byBhdHJhdsOpcyBkZTogcmVwb3NpdG9yaW9AdWZjLmJyIG91ICg4NSkzMzY2LTk1MDguCgpMSUNFTsOHQSBERSBESVNUUklCVUnDh8ODTyBOw4NPLUVYQ0xVU0lWQQoKQW8gYXNzaW5hciBlIGVudHJlZ2FyIGVzdGEgbGljZW7Dp2EsIG8vYSBTci4vU3JhLiAoYXV0b3Igb3UgZGV0ZW50b3IgZG9zIGRpcmVpdG9zIGRlIGF1dG9yKToKCmEpIENvbmNlZGUgw6AgVW5pdmVyc2lkYWRlIEZlZGVyYWwgZG8gQ2VhcsOhIG8gZGlyZWl0byBuw6NvLWV4Y2x1c2l2byBkZQpyZXByb2R1emlyLCBjb252ZXJ0ZXIgKGNvbW8gZGVmaW5pZG8gYWJhaXhvKSwgY29tdW5pY2FyIGUvb3UKZGlzdHJpYnVpciBvIGRvY3VtZW50byBlbnRyZWd1ZSAoaW5jbHVpbmRvIG8gcmVzdW1vL2Fic3RyYWN0KSBlbQpmb3JtYXRvIGRpZ2l0YWwgb3UgaW1wcmVzc28gZSBlbSBxdWFscXVlciBtZWlvLgoKYikgRGVjbGFyYSBxdWUgbyBkb2N1bWVudG8gZW50cmVndWUgw6kgc2V1IHRyYWJhbGhvIG9yaWdpbmFsLCBlIHF1ZQpkZXTDqW0gbyBkaXJlaXRvIGRlIGNvbmNlZGVyIG9zIGRpcmVpdG9zIGNvbnRpZG9zIG5lc3RhIGxpY2Vuw6dhLiBEZWNsYXJhIHRhbWLDqW0gcXVlIGEgZW50cmVnYSBkbyBkb2N1bWVudG8gbsOjbyBpbmZyaW5nZSwgdGFudG8gcXVhbnRvIGxoZSDDqSBwb3Nzw612ZWwgc2FiZXIsIG9zIGRpcmVpdG9zIGRlIHF1YWxxdWVyIG91dHJhIHBlc3NvYSBvdSBlbnRpZGFkZS4KCmMpIFNlIG8gZG9jdW1lbnRvIGVudHJlZ3VlIGNvbnTDqW0gbWF0ZXJpYWwgZG8gcXVhbCBuw6NvIGRldMOpbSBvcwpkaXJlaXRvcyBkZSBhdXRvciwgZGVjbGFyYSBxdWUgb2J0ZXZlIGF1dG9yaXphw6fDo28gZG8gZGV0ZW50b3IgZG9zCmRpcmVpdG9zIGRlIGF1dG9yIHBhcmEgY29uY2VkZXIgw6AgVW5pdmVyc2lkYWRlIEZlZGVyYWwgZG8gQ2VhcsOhIG9zIGRpcmVpdG9zIHJlcXVlcmlkb3MgcG9yIGVzdGEgbGljZW7Dp2EsIGUgcXVlIGVzc2UgbWF0ZXJpYWwgY3Vqb3MgZGlyZWl0b3Mgc8OjbyBkZSB0ZXJjZWlyb3MgZXN0w6EgY2xhcmFtZW50ZSBpZGVudGlmaWNhZG8gZSByZWNvbmhlY2lkbyBubyB0ZXh0byBvdSBjb250ZcO6ZG8gZG8gZG9jdW1lbnRvIGVudHJlZ3VlLgoKU2UgbyBkb2N1bWVudG8gZW50cmVndWUgw6kgYmFzZWFkbyBlbSB0cmFiYWxobyBmaW5hbmNpYWRvIG91IGFwb2lhZG8KcG9yIG91dHJhIGluc3RpdHVpw6fDo28gcXVlIG7Do28gYSBVbml2ZXJzaWRhZGUgRmVkZXJhbCBkbyBDZWFyw6EsIGRlY2xhcmEgcXVlIGN1bXByaXUgcXVhaXNxdWVyIG9icmlnYcOnw7VlcyBleGlnaWRhcyBwZWxvIHJlc3BlY3Rpdm8gY29udHJhdG8gb3UKYWNvcmRvLgoKQSBVbml2ZXJzaWRhZGUgRmVkZXJhbCBkbyBDZWFyw6EgaWRlbnRpZmljYXLDoSBjbGFyYW1lbnRlIG8ocykgc2V1IChzKSBub21lIChzKSBjb21vIG8gKHMpIGF1dG9yIChlcykgb3UgZGV0ZW50b3IgKGVzKSBkb3MgZGlyZWl0b3MgZG8gZG9jdW1lbnRvIGVudHJlZ3VlLCBlIG7Do28gZmFyw6EgcXVhbHF1ZXIgYWx0ZXJhw6fDo28sIHBhcmEgYWzDqW0gZGFzIHBlcm1pdGlkYXMgcG9yIGVzdGEgbGljZW7Dp2EuCg==Repositório InstitucionalPUBhttp://www.repositorio.ufc.br/ri-oai/requestbu@ufc.br || repositorio@ufc.bropendoar:2020-05-13T19:11:55Repositório Institucional da Universidade Federal do Ceará (UFC) - Universidade Federal do Ceará (UFC)false
