| ABSTRACT The objective of this study was to determine whether the type of bedding materials (sand, wood shavings, and paper) and of two chemical amendments (lime and bentonite) could interfere with litter quality (moisture, pH, and total bacterial counts), thereby influencing also the growth performance and the development of intestinal traits and cecum microbiota of chickens. Two hundred and seventy male Ross 308 broiler chickens were randomly assigned into nine treatment groups with three replicates per treatment. Broiler productive parameters, relative weight of different intestinal segments, content of cecal total bacterial counts (total aerobic bacteria, Lactobacilli, and coliforms), as well as litter moisture, pH, and total aerobic bacteria and... |

| Large quantities of poultry litter are being produced in Brazil, which contain appreciable amounts of phosphorus (P) that could be of environmental concern. To assess the immediate environmental threat, five poultry litters composed of diverse bedding material were incubated for 43 days under greenhouse conditions. The litters consisted of: coffee bean husk (CH); wood chips (WC); rice husk (RH); ground corn cobs (CC) and ground napier grass (NG) (Pennisetum purpureum Schum.), in which the change in forms of soluble P was evaluated using 31P NMR spectroscopy. On average, 80.2 and 19.8 % of the total P in the extract, respectively, accounted for the inorganic and organic forms before incubation and 48 % of the organic P was mineralized to inorganic P in 43... |
