Objectives

The formation of the Gir breed of cattle, at first aimed at creating an ethnic grouping Brazil capable of producing milk in the production system economically viable under tropical and subtropical regions.

The standards for training Girolando, developed in 1989, introduced at the time, a planned training of race bovine. This allowed work with objective parameters, giving more chance of success, reduce the time spent in achieving the goal and provide greater security to the financial investment of farmers engaged in the program.

Aimed at setting the standard racial mating is directed to the degree of 5 / 8 Hol + 3 / 8 Gyr, aiming for a productive cattle and standardized.

The use of heterosis is the most useful and extensive application of modern genetics, the process of rapid response, and also the method you can use more intensively the existing qualities in pure breeds.

Generally, the response level of hybrid vigor is greatest for characters with low heritability, and that in turn have higher economic value.
