this experiment was conducted to determine the effects of sodium bentonite litter supplement and stoking density on performance and litter quality using a total of 252 broiler chicks in completely randomized design with 6 treatments which were arranged factorially (3×2) and 4 replicates. experimental factors included: stocking density (14; low and 18; high /birds per m2) and three levels of sod...
the objective of this study was to evaluate whether the adverse effects of high dietary rice bran (rb) inclusion levels on the feed intake, performance, bone status and nitrogen (n) retention of broilers could be mitigated by wet feeding. giving a completely randomized design experiment in 2 × 2 factorial arrangement, seventy two broiler chickens, managed in 24 floor pens received one of the tw...
The effects of 4 different levels of nitrogen (0,120,150, and 180 kg nitrogen per hectare) and one level of poultry manure (10 tons per hectare) on the quantitative and qualitative characteristics of an autumn grown cultivar of cucumber [Cucumis sativus, cv.'super dominos] were studied in DarrehShahr, Ilam. The experiment was conducted in a completely randomized block design with 3 replications...
