1. Caracterização da freqüência de heterozigose em genes ligados à precocidade sexual em novilhas de corte compostas / Heterozigosity frequency characterization in genes related to sexual precocity in composite beef heifers
The luteinizing hormone receptor (LHR) and follicle-stimulating receptor (FSHR) genes, known for their influence on the onset of puberty were evaluated by PCR-RFLP analysis in a population of 370 European-Zebu composite beef heifers from different breed contributions. The objectives were to genetically characterize the investigated population using genotype

2. Estimation of additive direct and maternal genetic and non additive effects and prediction of the performance of weights, scrotal circumference and muscling scores in a Bos taurus x Bos indicus, composite beef cattle population. / Estimação de efeitos genéticos aditivos diretos e maternos e não aditivos e, predição do desempenho de pesos, perímetro escrotal e musculosidade em uma população de bovinos de corte compostos (Bos taurus x Bos indicus)
Data of weights at birth, weaning, 390 days, weight gain from weaning to 390 days, scrotal circumference and muscling scores at 390 days of age of a population used in the formation of the Montana Tropical® beef composite, raised under tropical conditions, were analyzed under three different models to: i) determine genetic and environment effects ii) determ
