1. Identification of genomic regions associated with backfat thickness in synthetic cattle.
Canchim is a synthetic beef cattle developed in Brazil which have good growth potential and tropical adaptation but suboptimal fat deposition. There are genomic regions associated with fat deposition already described, among them the centromeric region of BTA14. The scope of this work was to identify genomic regions associated with backfat thickness in Canch

2. Reproductive deficiency in bulls from synthetic breeds according to the type of crossbreed and the morphology of the Y chromosome
We used 550 Braford and 214 Brangus-lbagé bulls to study the association between Y chromosome morphology and the evaluation of breeding-soundness, karyotyping and breeding records were used to assess Y chromosome morphology. In general, no direct association was detected between the individual type of Y chromosome and reproductive fitness as previously esti

3. Quantificação dos estádios do ciclo espermatogênico em touros de raças sintéticas com e sem alteração na qualidade animal / Staging spermatogenic cycle in synthetic bulls with normal and altered semen quality
O objetivo deste estudo foi avaliar qual a freqüência dos túbulos seminíferos nos diferentes estádios do ciclo espermatogênico em touros de duas raças sintéticas, sendo 12 Braford e 8 Brangus-Ibagé, classificados em aptos (grupo A) e inaptos (grupo B) à reprodução, de acordo com o exame andrológico. Os estádios avaliados foram representativos d

4. Biometria testicular de touros da raça Crioula Lageana / Testicular biometry of the Crioula Lageana breed bulbs
The purpose of this experiment was to study the testicular morphologic parameters of the Crioula Lageana breed bulls, a breed that was threatened by extinction and, nowadays it is in recovery process through an association of creators. The experiment has developed with flocks of genetic preservation of the breed, linked to the Associação Brasileira de Cria
