    Caracterización clínica de la infestación por nematodo Rhabditis sp. y sus implicaciones en la producción bovina de la raza Gyr en Colombia
    (GRUPO DE INVESTIGACIÓN EN MEDICINA DE GRANDES ANIMALES - MEGA, 2023-08-09) Vergara Álvarez, Jheremmys David; Cardona Álvarez, José Alberto; Reyes Bossa, Bernardo José; Vergara Jheremmys
    En la actualidad la otitis parasitaria en ganado Gyr ha sido reportada en Colombia en los departamentos de Córdoba y Sucre, también se reportó en diferentes países la presencia de la enfermedad, estos cuentan con sistemas agroecológicos muy similares, igualmente reportan altas prevalencias y frecuencia de la enfermedad, pero los tratamientos han sido insatisfactorios en la mayoría de los países por lo que existe la necesidad de más estudios que busquen establecer un protocolo terapéutico adecuado y eficaz. La otitis parasitaria clínica es causada por nematodos Rhabditiformes, que ocasiona malestar en los animales de la raza Gyr, generando pérdidas económicas en la industria ganadera por la disminución en la producción de leche, ganancia de peso y mortalidad de animales de gran valor genético o comercial. Se pretende actualizar y generar conciencia en los médicos veterinarios sobre la caracterización clínica, el diagnóstico, el seguimiento epidemiológico y las estrategias de control de la enfermedad.

    Manejo agronómico integrado del pasto Angleton (Dichantium aristatum Benth) en el departamento de Córdoba
    (2022-08-25) Muñoz Pretel, César Augusto; Paternina Durango, Elisa
    The angleton grass (Dichantium aristatum Benth), is a perennial grass that grows in the form of macolla develops quickly and forms bunch with height between one and two meters, and has a high leaf - stem ratio. Rest periods of 40 days should be managed in average and in dry season up to 60 days of rest. It supports an animal load of two animals per hectare. Herbaceous perennial plant, usually erect, but with high planting densities can form grass, the leaves are lanceolate, has a wide range of adaptation to climate and soil, grows very well in medium fertility soils, with a wide range of pH and texture, is considered as invasive because of the high fertility of its seed, good persistence under grazing and competes with weeds and is well associated with legumes such as Arachis, Desmodium, Pueraria and Centrosema. In tropical areas it grows from sea level up to 1400 m and with rainfall greater than 850 mm per year. It responds well to levels of high fertilization. The great challenge of producers who practice modern livestock is to increase the production of meat and milk in an accelerated and sustainable way, so as to guarantee the demand of the population and, in addition, ensure the conservation of natural resources and the environment by minimizing the purchase of chemical inputs, reducing pollution and destroying natural resources.

    Patologías asociadas a la deficiencia de cobre y zinc que afectan al ganado bovino
    (2021-07-15) Lengua Durango, Diana Patricia; Cardona Álvarez, José Alberto
    At present, the study of micromineral deficiency in bovines has been an uncommon topic, and it has not been a specific objective in terms of bibliographic differentiation, but it has had a great boom in terms of type conservation. physiological and behavioral in terms of its pathogenesis and conditions in the reproductive field, so according to a review of a set of mineral studies such as copper and zinc are highly fundamental, and the lack of mineral homeostasis within the bovine organism can cause the presentation of different pathologies related to them, so their study is necessary, so it is possible to conclude that not only the lack of mineral contribution in the case of a research approach (Copper and Zinc) can produce this deficit, but also the presentation of antagonists, which are another set of minerals or compounds that in large quantities do not allow absorption and subsequently block the function of the mineral within the body of the animal causing alterations.

    Influencia de los trastornos podales en la producción bovina
    (2021-07-14) Pérez López, Nataly; Cardona Álvarez, José Alberto
    During the last decades, within our country, livestock farms have been in high growth, so the conditions regarding the management and exploitation of livestock management have been in constant metamorphosis. All this growth has led to an exponential improvement according to the functioning, control and management of disorders and diseases that in previous times were not given importance, but with the offer provided by studies, they have diagnosed that all these generate a series of losses not only for the animal but also for keepers, and farmers in general, so it is necessary to study the problem of leg disorders in bovine populations, since this predisposes to a decrease in milk production, and of Similarly, there are many risk factors, such as environmental, care, and genetic factors that increase the chance of cattle suffering from lameness, which is the most common disorder within dairy establishments. Based on all the above, a perceptual approach is sought and issued in terms of control and prevention according to risk factors so that cattle do not suffer from this disorder and those that already suffer from it can have an optimal and rapid improvement.
