DEEP LITTER PIG PRODUCTION SYSTEM AS A SUSTAINABLE ALTERNATIVE FOR SMALL FARMERS

Small backyard farmers produce pigs mainly on concrete floors, which generates wastewater rich in nitrogenous substances created by the continuous washing of sheds. The objective this study was to integrate a systematic review information deep litter pig production system (SPCCP) as an environmentally sustainable alternative for small Mexico. SPCCP uses layer absorbent organic matter animals are kept. This technology is considered economical implement, it requires less infrastructure. height bedding that favours transformation 50 60 cm. Agricultural by-products such plant debris or stubble can be used bedding. productive parameters (CP) adequate, with lower labour costs, and have more time eat, drink play, improves animal welfare. product obtained from bed at end cycle has desirable properties regenerate degraded soils enrich agricultural crops. simple efficient, infrastructure equipment required economical; feed conversion daily weight gain, benefits health comfort. Since does not require sheds, reduces labour, well water needs, generate wastewater. Therefore, complies technical, financial, environmental, welfare characteristics; producers.
