| dc.description | The investigative study focused on analyzing the nutritional properties of two varieties of alfalfa (Medicago sativa) subjected to physical mutation via gamma rays. This technique is common in crop genetic improvement as it can generate genetic variability and express new phenotypic characteristics. The effects of irradiation on the nutritional composition of alfalfa were evaluated, focusing on protein, fat, fiber, moisture, and ash. The results showed a significant impact of irradiation on the nutritional composition. There were notable differences in protein, where the improved variety exhibited the highest content with a dose of 300GY, followed by doses of 200GY, while the lowest dose (100GY) showed the lowest content. There were no significant differences in fat between the varieties and doses of irradiation. However, differences were observed in fiber, moisture, and ash. The variability in alfalfa's response highlights the importance of carefully choosing irradiation conditions to maximize desired changes in its nutritional composition. The results suggest that gamma irradiation may be effective in improving the nutritional quality of alfalfa and potentially increasing its value as livestock forage. | es_ES |

| dc.description.abstract | El estudio investigativo se enfocó en analizar las propiedades nutricionales de dos variedades de alfalfa (Medicago sativa) sometidas a mutación física mediante rayos gamma. Esta técnica es común en el mejoramiento genético de cultivos, ya que puede generar variabilidad genética y expresar nuevas características fenotípicas. Se evaluaron los efectos de la irradiación en la composición nutricional de la alfalfa, centrándose en proteína, grasa, fibra, humedad y ceniza. Los resultados mostraron un impacto significativo de la irradiación en la composición nutricional. Hubo diferencias destacadas en proteína, donde la variedad mejorada exhibió el contenido más alto con una dosis de 300GY, seguida por dosis de 200GY, mientras que la dosis más baja (100GY) mostró el contenido más bajo. No hubo diferencias significativas en grasa entre las variedades y dosis de irradiación. Sin embargo, se observaron diferencias en fibra, humedad y ceniza. La variabilidad en la respuesta de la alfalfa destaca la importancia de elegir cuidadosamente las condiciones de irradiación para maximizar los cambios deseados en su composición nutricional. Los resultados sugieren que la irradiación con rayos gamma puede ser efectiva para mejorar la calidad nutricional de la alfalfa y potencialmente aumentar su valor como forraje para el ganado. | es_ES |
