dc.description | 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. | es_ES |

dc.description.abstract | La falta de alimento con buenos parámetros nutritivos y productivos en el área ganadera ha sido un problema que se ha tratado de solucionar con el pasar de los años, gracias a la ciencia y los avances tecnológico, en la actualidad se está llegando a grandes cambios. Este trabajo de investigación documenta la incidencia del mejoramiento genético en la alimentación animal, dando a conocer las técnicas, que se pueden llegar a implementar en pastos, para de esa manera poder tener un mayor rendimiento en la producción de pastizales, con mayor valor nutritivo, con una resistencia a los cambios climáticos, al pizote de los animales y al sobre pastoreo, esto con lleva a restructurar al número de animales por potreros. Toda la información se recopilo de artículos científicos, libros, tesis y trabajos experimentales con estudios ya ejecutados. El uso de los rayos gamas con dosis de 52Gy en investigaciones realizadas a demostrado buenos resultados en el pasto Janeiro (Eriochloa polystachya) llegando a desarrollar una altura de la planta de hasta 246,07cm, con un diámetro del tallo de 3,27Mm, incluso se ha llegado alcanzar 16,23cm en la longitud de la hoja y de ancho 1,44cm. El uso de la combinación de pastos mejorados con un 51,8% y pastos naturales bien cuidados con un 48,2%, también da buenos resultados llegando a soportar 4,47 U.A en 2.6ha con una producción de litros de leche por día de hasta 7,04 con 3,63 vacas de ordeño, en comparación con la combinación de pastos naturales (53%) y pastos mejorados (46,2%) que solo soporta 1,69 U.A en 1,72ha, llegando a producir 5,89 litros de leche por día con 1,26 vacas de ordeño. | es_ES |
