| dc.description | A documentary research was carried out with the aim of generating information on solutions to environmental contamination problems caused by pig excreta. The research was of a bibliographic documentary type by the inductive deductive method, it was prepared based on the collection and review of scientific articles and books published on the web, on issues related to the environmental impact produced by pig excreta. The collection of information was carried out between the months of July and September 2020. This bibliographic research allowed to demonstrate the development of many methods of treatment of pig excreta, to try to reduce its polluting value and mitigate the negative effects on health. public. Among them are modifying the diet, in such a way that the animals consume the necessary nutrients according to their nutritional requirements in each stage, addition of phytases in the diet to increase phosphorus efficiency and thus decrease total phosphorus and consequently decrease excretion. phosphorus to the environment. In the same way, the treatments to the excreta can be carried out by adding exogenous enzymes that reduce the generation of ammonia from the excreta (and corrosion), as well as the use of bioreactors, biodigesters, use of deep bed, etc., which in They generally have the purpose of reducing the load of pollutants present in the excreta and thus being able to use them either in agriculture or as a food resource for other animals. | es_ES |

| dc.description.abstract | Se realizó una investigación documental con el objetivo de generar información sobre soluciones a los problemas de contaminación del medio ambiente causado por las excretas de los cerdos. La investigación fue de tipo documental bibliográfica por el método inductivo deductivo, fue elaborado en función a la recopilación y revisión de artículos científicos y libros publicados en la web, en temas vinculados al impacto ambiental producido por las excretas de cerdos. La recopilación de información se realizó entre los meses de julio y septiembre del 2020. Esta investigación bibliográfica permitió demostrar el desarrollo de muchos métodos de tratamiento de las excretas de los cerdos, para tratar de reducir su valor contaminante y mitigar los efectos negativos en la salud pública. Entre ellos están modificar la dieta, de tal forma que los animales consuman los nutrimentos necesarios de acuerdo a sus requerimientos nutricionales en cada etapa, adición de fitasas en la alimentación para aumentar la eficiencia del fósforo y así disminuir el fosforo total y consecuentemente disminuir la excreción de fósforo al ambiente. De igual forma los tratamientos a las excretas se los puede realizar al adicionar enzimas exógenas que reduce la generación de amoniaco de las excretas (y la corrosión), así como el uso de biorreactores, biodigestores, utilización de cama profunda, etc., que en general tienen un propósito de disminuir la carga de contaminantes presentes en las excretas y así poderlas utilizar ya sea en la agricultura o bien como un recurso alimenticio para otros animales. | es_ES |
