Resumo: | Different buffers are used in the solution for washing and embryo maintenance during the procedures of equine embryo transfer (EET). The buffers carbonate, phosphate, and zwitterionic are the most used. During the procedures of transference, it is common to keep the embryos into the maintenance solution during a time longer than previewed. This experiment was realized with the objective of comparing the costs and benefits of using two solutions with different buffers for embryo transfer in mares of the breeding Mangalarga Marchador. The solutions are DPBS (phosphate) and Embriocare® (zwitterionic). The embryos were divided randomly in two treatment , zwitterionic and phosphate, and kept in the solution for 0, 30, 60, and 120 minutes. The results indicate that both solutions are efficient (P > 0.05) in the processes of scanning, washing, maintenance at ambient temperature for different time periods (0 to 120 minutes), and inovulation of equine embryos under tropical conditions. The pregnancy rates using the solution were 65% and 69.7%. The greatest pregnancy rate using DPBS was obtained with embryos kept in the solution for 60 minutes (P < 0.05). Using zwitterionic buffer, the greatest rate of pregnancy was obtained with embryos kept during 30 minutes in the solution (P < 0.05). Since Embriocare® is more expensive, DPBS presented the best cost-benefit ratio.KEY WORDS: Embryo transfer, equine, Mangalarga Marchador, phosphate and zwitterionic buffer. |

Os mais usados são carbonato, fosfato e zwitteriônico. Durante os procedimentos de transferência é comum que o embrião permaneça por um tempo maior que o previsto em espera no meio de manutenção utilizado. Este experimento foi realizado com o objetivo de comparar o custo–benefício de dois meios contendo tampões diferentes DPBS (fosfato) e Embriocare® (zwitteriônico), na transferência de embriões em éguas da raça Mangalarga Marchador. Dividiram-se os embriões aleatoriamente em dois tratamentos – zwitteriônico e fosfato –, permanecendo em descanso por 0, 30, 60 ou 120 minutos em ambos os meios. Os resultados indicam que esses tampões são igualmente eficientes (P > 0,05) nos processos de rasteamento, lavagem, manutenção à temperatura ambiente por diferentes períodos de tempo (0 a 120 minutos), sendo que as taxas de prenhez obtidas em ambiente tropical foram de 65% e de 69,7%, respectivamente. Porém, obteve-se a maior taxa de prenhez encontrada com DPBS com um tempo de manutenção do embrião por sessenta minutos no meio (P < 0,05). No tampão zwitteriônico, a maior taxa de prenhez foi alcançada com trinta minutos no meio (P < 0,05). Como a aquisição do Embriocare® foi mais onerosa, o DPBS apresentou o melhor custo–benefício.PALAVRAS-CHAVES: Equino, Mangalarga Marchador, transferência de embriões, tampão fosfato e zwitteriônico.Palavras-chave: eqüino, Mangalarga Marchador, transferência de embriões, tampão fosfato e zwitteriõnico.Universidade Federal de Goiás2009-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdfhttps://revistas.ufg.br/vet/article/view/451410.5216/cab.v10i3.4514Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 10 No. 3 (2009); 938-946Ciência Animal Brasileira / Brazilian Animal Science; v. 10 n. 3 (2009); 938-9461809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/4514/5416Caiado, José Renato Costavan Tilburg, Mauricio FragaFonseca, Francisco AloísioSilva, José Frederico StraggiottiFagundes, BrunoBarreto, Marcus Antonio Pessanhainfo:eu-repo/semantics/openAccess2009-09-30T20:55:22Zoai:ojs.revistas.ufg.br:article/4514Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2009-09-30T20:55:22Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)false |
