an experiment was carried out to estimate growth parameters of broiler chickens received artichoke extract in their drinking water using gompertz non-linear model and to compare gompertz non-linear regression equation and artificial neural network modeling in terms of their ability to predict body weight of broiler chicks at day 42 of age. a total number of 250 one- day- old ross 308 broiler ch...

nowadays soil contamination with heavy metals is considered as one of the most serious environmental concerns. among the heavy metals, lead due to inverse impacts on human health and substantial environmental problems causes major concern.this study was carried out with the aim of assessing the ability of different corn cultivars in a greenhouse condition for the accumulation of lead metal. tre...
