Alternativas de Manejo de las Excretas Porcinas

Abstract

One of the principal problems that the swine farms face is the disposal of the feces which are produced in large quantities and must be taken away daily from the barnyards and other installations where the pigs remain; this is why the evolution of alternatives of handling the swine feces constitutes a practical guide on the solution to a great problem through the application of cleaner technologies produced upon using some of the alternatives previously stated to improve the alimentary efficiency and thence the retention of nutrients in the animal, total consumption of the alimentary compounds, facts which mean less environment contamination. Worldwide, the greatest problem faced by the swine exploitations is the generation of feces, which having a great nutrient potential, contaminate the environment and can become the principal obstacle for the future development of the animal industry. The pig feces have traditionally been handled in a pig-pasturemilk system, taking advantage of the soil improvement for pasture with organic matter fertilization to attain a major milk production. This is why it is recommended to use the pig feces as fresh, dry or bio-degraded as a fundamental protein component, plus the addition of fibers in the bovine and sheep feeding both for initial ages and adult ages.
