in order to compare the effects of different weaning strategies on feed intake, structural growth measurement and health, blood metabolites and economic efficiency of young dairy calves, twenty four female holstein calves were used. calves after birth were randomly assigned into one of three weaning strategy as follow: 1) weaning based on feed intake, 2) weaning based on weight gain (30 kg weig...

high moisture levels in fresh dairy manure provide a suitable environment for growth of pathogens and cause environmental pollution. dry manure can be used for different purposes in agriculture and in livestock industry. such heat properties of manure as specific heat, thermal conductivity and thermal diffusivity are important needed factors for the design and development of a suitable efficien...

a synoptic method based on stream analysis is applied to understand the governing mechanism of summer rainfall occurrence in the south of iran. based on this, the rainfall data of 152 stations of iran were analyzed for a 33-year period (1970-2002). investigating the spatial and temporal distribution of summer rainfall, a typical rainy region is recognized in the south east of iran. it is found ...

the behavior of suspended sediment during flood events is not only a function of energy conditions, i.e. sediment is stored at low flow and transported under high flow conditions, but also is related to the variations in sediment supply and sediment depletion. these changes in sediment availability result in so-called hysteresis effects. therefore, hysteresis pattern analysis is of great import...
