- W2729212984 abstract "O gado Pantaneiro e um taurino adaptado a regiao do Pantanal, resistente a endo e ectoparasitas e as variacoes climaticas caracteristicas deste bioma. Durante muito tempo, foi a base da economia pantaneira. Porem, com o tempo, esse tipo de bovino local foi substituido gradativamente por racas zebuinas, ocasionando um intenso processo de diluicao genetica que atualmente resulta em sua quase extincao. Devido a importância cultural e historica da raca Pantaneira, este trabalho teve como objetivo a genotipagem de animais desta raca para o polimorfismo existente na regiao 5? do gene candidato TG5, previamente relacionado com a qualidade carnea. Foram genotipados, por PCR-RFLP, 69 animais provenientes do Nucleo de Conservacao da Embrapa, localizado na Fazenda Nhumirim em Corumba-MS. As frequencias alelicas observadas foram de 57,2% para o alelo T e 42,8% para o alelo C. Foram observados 28,98% de animais com o genotipo considerado favoravel (TT). A heterozigosidade observada foi de 0,565 e a diversidade genica para o polimorfismo analisado foi de 0,493. A presenca do alelo T em frequencia superior a 57% evidencia o potencial que as racas naturalizadas quando se fala em produtos com maior qualidade e valor comercial agregado. Pantaneiro taurine cattle adapted to the Pantanal region, is resistant to ecto and endoparasites and to climatic variations and characteristics of this biome. For a long time, this population was the economic basis of the Pantanal. However over time, this local type was gradually replaced by zebu breeds, causing an intense process of genetic dilution that currently results in near extinction. Due to cultural and historical importance of the Pantaneira breed, this work aimed at genotyping animals for polymorphism in the 5? region of the candidate gene TG5, previously related to the quality of meat. Sixty nine animals from the Center for Conservation in Fazenda Embrapa Nhumirim in Corumba-MS were genotyped by PCR-RFLP. The allele frequencies observed were 57.2% for the T allele and 42.8% for allele C. An 8.98% of animals presented the genotype considered favorable (TT). The observed heterozygosity was 0.565 and the genetic diversity for polymorphism analysis was 0.493. The frequence of the T allele greater than 57% suggests the potential that this naturalized breeds to give high quality and value added products." @default.
