Description:	Since Guzera is a dual-purpose breed, both the MOET Nucleus and various partner herds of the dairy breeding program also participate in the Genetic Evaluation Program of the Guzera Breed for Beef Production (PAGRG) of ANCP and GEMAC. Consequently, several sires are ?double proven?, i.e., they are genetically evaluated for dairy and beef traits. This summary reports for the 11th consecutive year the results of genetic evaluations of beef and reproductive traits in different proven sires for milk. Conformation and management traits can help the breeder to obtain a herd with better production and economic efficiency. Several of these traits are being measured in the Guzera breed and this summary presents the evaluations of sires that met the accuracy requirements for some of them. Molecular markers are promising tools that can be used complementarily in selection programs. Caution in the use of these marker in Zebu cattle is necessary since they are still being tested for validation. Since various molecular markers have already been studied in Guzera cattle, the genotypes of different proven sires are presented in the summary, particularly in an attempt to preserve some rare alleles and to assist in selection with due caution. The economic importance of the different traits evaluated and presented in this summary varies widely across different niche markets and systems in which the breed is used. We decided to present the evaluations for the largest possible number of traits so that producers can choose those that are most appropriate and important for their particular objective and use reliable data in their selectin work and breeding schemes. The main goal of the program is to generate technology and to produce improved animals for production systems that take advantage of the qualities of Guzera cattle and their crossbreeds in order to obtain high production at low cost.
