Resumo: | The objective was to evaluate additional strategies in protocols of fixed-time artificial insemination (TAI), as the follicular dynamics and pregnancy rate. Four studies were conducted. In study 1 it was evaluated the effect of the administration of recombinant bovine somatotropin (rbST) at the time of application of the TAI protocol. At work 2 it was evaluated the effect of injectable administration of supplements of amino acids and polypeptides, since the day of birth until the time of application of the TAI protocol. At work 3 it was evaluated the influence of the administration of flunixin meglumine (FM) at the moment of maternal recognition of pregnancy over the pregnancy rate of heifers and cows, previously submitted to TAI protocols. At work 4 it was evaluated the efficiency of three different ovulation inducers: estradiol benzoate (EB), estradiol cypionate (EC) and gonadotropin releasing hormone (GnRH) in TAI protocols. It wasn t verified in any study the marked influence between the treatments over the evaluated patterns on follicular dynamics and over the ovulation rate. In study 1 there was no interaction of the main effects, the administration of rbST and the cyclicity of cows for the pregnancy rate. The pregnancy rate in cows receiving rbST was lower for those who had anestrus, compared with cyclic cows (P <0.05). At work 2 the pregnancy rate was influenced by the previous administration of the amino acids and polypeptides supplements (P <0.05).The pregnancy rate was higher for the cyclic cows in relation to the anestrus ones (P <0.05).At work 3 the administration of the (FM) at the time of the maternal recognition of pregnancy did not alter the pregnancy rate in cows and heifers. At work 4 the administration of the different inductors of ovulation, EB, EC, and GnRH at TAI protocol in crossbred cows did not alter the pregnancy rate(P>0.05). |

Foram realizados quatro trabalhos. No trabalho 1 foi avaliado o efeito da administração de somatotropina bovina recombinante (rbST) no momento da aplicação do protocolo de IATF. No trabalho 2 foi avaliado o efeito da administração injetável de suplemento de aminoácidos e polipeptídeos, desde o dia do parto até o momento da aplicação do protocolo de IATF. No trabalho 3 foi avaliada a influência da administração de flunixin meglumine (FM) no momento do reconhecimento materno da gestação sobre a taxa de prenhez de novilhas e vacas, submetidas previamente a protocolos de IATF. No trabalho 4 foi avaliada a eficiência de três diferentes indutores da ovulação: benzoato de estradiol (BE), cipionato de estradiol (CE) e hormônio liberador das gonadotrofinas (GnRH), em protocolos de IATF. Em nenhum trabalho foi verificado influência marcante entre os tratamentos sobre os padrões avaliados de dinâmica folicular e sobre a taxa de ovulação. No trabalho 1 não houve interação dos efeitos principais, com taxa de prenhez. A taxa de prenhez nas vacas recebendo rbST foi menor para as que se apresentavam em anestro, comparando com as vacas cíclicas (P<0,05). No trabalho 2 a taxa de prenhez sofreu influencia da administração prévia de suplemento de aminoácidos e polipeptídeos (P<0,05). A taxa de prenhez foi maior para as vacas cíclicas em relação às em anestro (P<0,05). No trabalho 3 a administração do (FM) no momento do reconhecimento materno da gestação não alterou a taxa de prenhez das vacas e novilhas. No trabalho 4 a administração dos diferentes indutores da ovulação, BE, CE, e GnRH, em protocolo de IATF em vacas mestiças não alterou a taxa de prenhez.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de ViçosaDoutorado em ZootecniaUFVBRGenética e Melhoramento de Animais Domésticos; Nutrição e Alimentação Animal; Pastagens e ForragiculIATFrbSTGnRHVacas mestiçasTAIrbSTGnRHCrossbred cowsCNPQ::CIENCIAS AGRARIAS::ZOOTECNIA::PRODUCAO ANIMALEstratégias adicionais em protocolos de inseminação artificial em tempo fixo em fêmeas bovinasAdditional strategies in protocols of timed artificial insemination in cowsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf1301532https://locus.ufv.br//bitstream/123456789/1854/1/texto%20completo.pdf7a47602d5a8df5369b65f5a7956f900eMD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain278488https://locus.ufv.br//bitstream/123456789/1854/2/texto%20completo.pdf.txt9716dc3e8985ad0747b32b8c9a2388f4MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3557https://locus.ufv.br//bitstream/123456789/1854/3/texto%20completo.pdf.jpged79bd14794743072128fce8dc6ec78fMD53123456789/18542016-04-07 23:15:47.256oai:locus.ufv.br:123456789/1854Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-08T02:15:47LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
