Alternativas de Manejo para Redicir el Impacto Contaminante de las Excretas Bovinas en los Establos Lecheros.

Abstract

With the aim of reducing the pollutant effect of bovine expels in milk farms, some mitigation alternatives have been proposed through research to elaborate organic fertilizer from this manure such as compost and bokashi, which are used in agriculture. Eventually these expels were used to produce biogas and bio fertilizer, getting this way, a maximum benefit of this waste from the farms through turning them into energy and fertilizers for the soil. Currently, some strategies to reduce manure pollution are being used which help in increasing energetic concentration and increasing food digestibility, by selecting cattle by their physiology, ruminal microbiology which makes them to have faster food pass since bacteria producers of methane catch hydrogen from fermentation to take it out from ruminal environment.
