two hundred and twenty one-day male chicks (ross 308) were used in a completely randomized design with 5 treatments and four replicates each to investigate the effects of the different levels of 0.15, 0.3 and 0.6 percent rosemary extract along with nitrate (27.4 mg sodium nitrate/liter water) in drinking water on growth, some blood parameters and carcass characteristics of broiler chickens. no ...

A total of 220 broiler chicks in five groups were used to reveal the effects of different levels of 0.0, 1.5, 3.0 and 6.0 mL/L rosemary extract along with sodium nitrate (27.4 mg/L) in drinking water as compared to the control (without any supplement in water) on performance and antioxidant potential of treated broiler chickens. Body weight gain and feed conversion ratio were negatively affecte...

abstract   background: the compounds which contain nitrogen entering the environment can cause some problems, such as eutrophication for water resources and potential risk for human health because of methemoglobinemia and cancer. biological techniques are effective in removing nitrate. the aim of this study was to remove nitrate from groundwater using denitrification. the main objectives of thi...

an experiment was conducted with two hundred and twenty day-old male broiler chicks (ross 308) in five groups to investigate the effects of different levels of 0, 0.2, 0.4 and 0.6% thyme extract in drinking water (including 27.4 mg sodium nitrate per liter) on broiler performance and antioxidantstatus and blood gas indices. no significant differences were observed between the treatments for bod...

to evaluate the most suitable method as well as different conditions of blanching in the process of green tea production from local tea green leaves, this research was conducted in split plot in time and on the basis of a randomized complete block design of six treatments in 3 replications (different plucking times). two common methods of blanching by steaming and panning were used. green leaf ...
