Incidencia del mejoramiento genético de pastos en la alimentación animal.

The lack of food with good nutritional and productive parameters in the livestock area has been a problem that has been tried to be solved over the years, thanks to science and technological advances, great changes are currently being reached. This research work documents the incidence of genetic improvement in animal feed, revealing the techniques that can be implemented in pastures, in order to have a higher yield in the production of pastures, with greater nutritional value, with a resistance to climatic changes, to the coati of the animals and to overgrazing, this leads to restructuring the number of animals per paddock. All the information was collected from scientific articles, books, theses and experimental works with studies already carried out. The use of gamma rays with doses of 52Gy in research carried out has shown good results in Janeiro grass (Eriochloa polystachya), reaching a plant height of up to 246.07cm, with a stem diameter of 3.27mm. It has even reached 16.23cm in blade length and 1.44cm width. The use of the combination of improved pastures with 51.8% and well-kept natural pastures with 48.2%, also gives good results, reaching 4.47 A.U. in 2.6ha with a production of liters of milk per day of up to 7.04 with 3.63 milking cows, compared to the combination of natural pastures (53%) and improved pastures (46.2%) that only supports 1.69 A.U. in 1.72ha, reaching 5, 89 liters of milk per day with 1.26 milking cows.
