Abstract

Bovine breeds starded to be selected in the old world, during the 19thcentry. The starting populations werw varieties of cattle adapted by natural selection to the local enviroment. Now a days, a large quantityof spceialized bovine breeds are spread all over the world. Several ofthese are exploited for meat proction in Brazil. The objective of the present work was to investigate the genetic ralationsphip among some of these breeds, representing beef cattle from different categories: Caracu, a European breed adaptded to tropical environment, Simmental, a continental european breed, Aberdeen Angus, a representative of British Isles breeds, Canchim, a crossbred (5/8 Charolais, 3/8 Bos indicus) and Nellore, The most relevant Bos indicus beef cattle breed in Brazil.

Abstract

The Brazilian Nellore is a Bos indicus brees developed from animals imported from india up to the middle of this centry. Due to its high tolerance ti the tropical environment, the Nellore became the most popular beef cattle brees in Brazil. Besidies its importance as pure breed, it has been successfully used in commeercial crosses and in the composition of new breeds. Genetic variability providies the scenario for selection in animal breeding programs. Monitoring this variabilty through molecular marker analysis can be useful to prevent genetic erosion. The objective of this study was to charactize Nellore animals based on restriction fragment lenth polymorphisms (RFLP) and microsatellites. Made available in DSpace on 2022-04-13T15:00:24Z (GMT).

Abstract

No presente trabalho 180 fêmeas da raça Nelore provenientes de oito rebanhos, foram analisadas quanto aos marcadores microssatélites TEXAN15BM1224 e CSFM50 e aos polimorfismo de comprimento de fragmentos de restrição (RFLP) nos locosk-caseína B-lactoglobulina e hormônio de crescimento (GH). Com exceção de GH, todos os marcadores foram polimórficos na amostra estudada. Os valores de heterizigosidade, diversidade gênica conteúdo de informação polimórfica (PIC) e probabilidade de exclusão de partenidade (PE) foram estimados. Os maiores valores de PIC (0.685) e PE (0.521) foram para o marcador BM1224.

Abstract

Summary: Candidate gene strategy has been proposed to direct the search for quantitative trait loci, and polymorphisms at these loci have been associated with several production traits in bovine. A total of 211 animals resulting from crosses between Nelore females with sires from either Aberdeen Angus, Canchim and Simmental breeds were analyzed for restriction fragment length polymorphisms (RFLPs) in the κ -casein, β -lactoglobulin (LGB) and growth hormone GH genes. Average daily gain from birth to weaning (GBW) and from weaning to yearling (GWY) were analyzed by a statistical model comprising RFLP genotypes and their interaction effects. Significant effects (p < 0.05) of growth hormone (GH ) and of the interaction β -lactoglobulin × GH were verified for the GWY. Animals with LL genotypes for GH had higher GBW than LV animals but lower GWY (p < 0.05). [ABSTRACT FROM AUTHOR]
