Abstract
In this study we provide results from a study of nine treatments with four replicates tested under field conditions consisting of 36 piles of 2 meters long and 1.5m wide and 1.0m high. Three piles were left at 25cm below the surface, three at 50cm below the surface and the other three on the surface with 0%, 25% and 50% moisture respectively, at three replications. Temperatures and samples for identification of parasites, were collected from two different scanning depths (0-7.5 and 7.5-15 cm). In the manure piles and non-solarized (control), samples were collected according to NOM-044-SEMARNAT-2002. Solarized for manure sampling was at the end of the period of solarization to determine Cryptosporidium parvum and Giardia lamblia. For the manure non solarized (control), there was a homogeneous mixture of the various stables in North area of the Ejido Fresno. The experimental results indicate that achieving an increase in temperatures in solarized piles. The pile with 50% moisture with an average measure of 56.41, under these temperatures was eliminated Cryptosporidium parvum and Giardia lamblia. In the sample of manure without solarization was detected the presence of Escherichia coli, F.enterobacteriaceae, Enterobacter sp., Bacille sp., Mucor sp. and F.Sanccharonmycetaceae, Cryptosporidium sp. and Giardia sp.
