| description | In the cattle context of Casanare, where access to technologies to evaluate seminal quality is limited, it would be beneficial to anticipate the seminal characteristics of bulls based on their physical attributes without resorting to specific and costly methodologies would be beneficial. This could improve herd reproductive efficiency, resulting in increased pregnancy rates and annual calf production. In an experimental study with 238 bulls, we measured various physical and seminal characteristics. We used Spearman's correlation coefficient was used to analyze the relationships between these characteristics. Our findings indicate that 57.1 % of the bulls were classified as very good, while 7.6 % were considered poor quality. The bulls had an average age of 5.5 years. Their semen motility and vitality were both 76% on average, and their average sperm concentration was 610 million. Strong negative correlations were found between libido, erection, protrusion, ejaculation and ejaculation type with seminal characteristics such as volume, lumps, motility, vitality and sperm concentration. Furthermore, there is a positive correlation between sperm concentration and scrotal circumference (SC), suggesting that an increase in SC may lead to an increase in sperm concentration. These correlations provide valuable information for selecting breeders and improving reproductive programs on livestock farms in Colombia, particularly in the case of cattle breeding. |

En el contexto ganadero de Casanare, donde el acceso a tecnologías para evaluar la calidad seminal es limitado, anticipar las características seminales de los toros basándose en sus atributos físicos sin recurrir a metodologías específicas y costosas sería beneficioso. Esto podría mejorar la eficiencia reproductiva del hato, aumentando los índices de preñez y la producción anual de crías. En un estudio experimental con 238 toros se midieron diversas características físicas y seminales, y se utilizó el coeficiente de correlación de Spearman para analizar las relaciones entre ellas. Se observó que el 57,1 % de los toros fueron clasificados como muy buenos, mientras que el 7,6 % fueron considerados de baja calidad. La edad promedio de los toros fue de 5,5 años, con una motilidad y vitalidad seminal promedio del 76 % para cada una. La concentración espermática promedio fue de 610 millones. Se encontraron correlaciones negativas fuertes entre la libido, erección, protrusión, eyaculación y el tipo de eyaculación con características seminales como volumen, grumos, motilidad, vitalidad y concentración espermática. Además, la concentración de espermatozoides mostró una correlación moderada positiva con la circunferencia escrotal (CE), lo que indica que un incremento en la CE tiende a aumentar la concentración espermática. Estas correlaciones proporcionan información valiosa para la selección de reproductores y la mejora de programas reproductivos en explotaciones pecuarias en Colombia, especialmente para aquellos productores con limitado acceso a tecnologías reproductivas.
