“…The decline occurred in the Salmonella population in our study was in agreement to that result reported by Kwak et al (2005). They, also, reported that Salmonella and E. coli were eliminated in a shorter period in DBL compared to non-stacked BL.…”

“…Chaudhry et al (1998) recorded maximum temperatures of 64 • C and 60 • C on day 7 for 80 and 40 cm depths, respectively. In another work, the temperature increased and reached its maximum (62 • C) on day 6 of deep stacking (Kwak et al, 2005). The differences in results reported in the studies could be related to some factors such as different deep stacking methods, capacity of stack and mean ambient temperature.…”

“…The values observed in our study were in the safety ranges outlined above. This was due to heat produced during fermentation of DBL which was sufficient to kill any pathogenic bacteria (Kwak et al, 2005). The elimination of Coliform bacteria in DBL containing 350 g moisture/kg at depths 30 and 60 cm could, in part, be due to sensitivity of these bacteria to temperatures above 42 • C (McCaskey et al, 1985) and also the accumulation of ammonia-N released from the breakdown of uric acid during the deepstacking process (McCaskey and Martin, 1988).…”

“…This temperature was not recorded at depth 60 cm with moisture 250 g/kg and depth 120 cm. The increased temperature in DBL is due to the biological activity of microorganisms (i.e., microbial growth and metabolism which generate heat) (Kwak et al, 2005). The greater temperature in the shallower depths of DBL (depths 30 and 60 cm) than the deeper depth (depth 120 cm) was due to higher levels of oxygen at the shallower depths stimulating the growth of aerobic microbes which generate heat (Kwak et al, 2005), and indicate more aerobic than anaerobic fermentation at the top Table 7 Effects of the experimental diets on ruminal parameters and rumen protozoa (log10/g digesta) in sheep fed diets contained deep-stacked broiler litter (DBL).…”

“…In the study of Kwak et al (2005) on the effect of composting of broiler litter by piling (1.2m high) in the elimination of Escherichia coli, Salmonella enteritidis and Shigella sonnei, it was observed that these pathogens were eliminated between day 2 and 4 of composting, and that the highest temperature recorded was 62°C on day 6 of fermentation.…”

Broiler litter reutilization consists in using the same bedding material to cover the house floor for several broiler flocks. This requires the litter to be treated in order to reduce the amount of microorganisms, according to international recommendations. The aim of this study was to evaluate two methods of broiler litter fermentation based on composting concepts and their effect on litter and the air quality during fermentation in small-scale broiler houses. The experiment was carried out in the Environmental Laboratory I of the School of Agricultural Engineering of the State University of Campinas, utilizing six smallscale houses. Litter from the same grow-out (one, two or three) was distributed in two experimental houses, where it was either piled or spread. Before beginning the treatment, six litter samples were collected from each house and analyzed for total nitrogen content, humidity, pH and microbial counts. Litter humidity, gas emission (NH 3 and CO 2 ), environmental temperature, air relative humidity, and air velocity were determined during and after composting. Bacterial population, especially of Salmonella sp, was higher when the litter was piled compared with spread litter. However, fungi population showed a different pattern, decreasing after composting. Nevertheless, both treatments were not able to significantly reduce bacterial counts, specifically Salmonella sp, when the population before and after fermentation were compared. INTRODUCTIONThe poultry industry is one of the fastest growing sectors of global agribusiness because of the increasing demand for animal protein, including meat and eggs. However, one of the main challenges of modern poultry production is the disposal of waste, particularly of broiler litter (Bolan et al., 2010). At the same time, the poultry industry also faces litter availability problems because of the increasing demand. Therefore, different substrate types and qualities available in the market need to be used (Bigili et al., 2009).Litter is used to provide comfort to the birds and to maintain carcass quality, as it reduces the incidence of breast and footpad lesions, as well of lesions in other less commercially important parts (Oliveira et al., 2002).According to Kelleher et al. (2002), litter and waste predominantly consist of water, carbon (C), nitrogen (N) and phosphorus (P), and lower levels of chlorine (Cl), calcium (Ca), magnesium (Mg), sodium (Na), manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), and arsenic (As). These levels vary among broiler houses and regions, depending on the substrate, number of flocks reared, drinking systems, hygiene status, cleaning method, and storage (Edwards & Daniel, 1992;Jacob et al., 1997;Dao & Zhang, 2007
