this study was carried out to evaluate the effect of onion extract on growth performance, carcass characteristics and some blood metabolites in ross and cobb broiler chickens. one hundred sixty, 1-d-old broiler chickens (mean initial weight: 36.5 ± 1 g) of male sex (ross-308 and cobb) were randomly conducted as randomized complete design with 4 treatment and 4 replication. the experimental grou...

reducing nitrogen status of floriculture plants is an effective tactic in pest management by decreasing host plant quality. life table parameters and population growth rate of aphis craccivora(hemiptera: aphidiae), as well as cosmetic and qualitative parameters losses associated with aphid infestation were evaluated in relation to n fertilization levels on gomphrena globosa, under greenhouse co...

Emergency departments (EDs) have been becoming increasingly congested due to the combined impacts of growing demand, access block and increased clinical capability of the EDs. This congestion has known to have adverse impacts on the performance of the healthcare services. Attempts to overcome with this challenge have focussed largely on the demand management and the application of system wide p...

today, economic and environmental performance are tightly closed to each other. the natural environment plays an important role in supporting economic activity; directly, by providing resources and raw materials such as water, timber and minerals that are required as inputs for the production of goods and services; and indirectly, through services provided by ecosystems including carbon seques...

an experiment was conducted in order to assess the effects of different levels of dietary canola meal (cm; 0, 10 and 20 %) and copper (0, 125 and 250 mg/kg) on performance, susceptibility to ascites syndrome and some blood metabolites of broiler chickens. during a six week period of experiment, a total of 495 male broilers (ross 308) were used in completely randomized design with a 3×3 factoria...

This study was conducted to evaluate the effect of scent leaf meal on growth performance, blood and serum parameters growing cockerels. A total ninety-six (96) Isa-brown day-old cockerel chicks were used in a completely randomized design experiment. The birds randomly allotted four dietary treatments consisting basal diets supplemented with (SLM) at rate 0% (control), 1%, 2% 3% representing T1,...

This research was taken to improve the performance of native duck. Two duck varieties, Rupali and Nageswari 6th generation were selected aiming increase their laying performances. A total 540 ducklings both genotypes hatched brooded in brooder house. Male female ducks separated marked with wing band at 12 weeks age. At 40 age, a 300 genotype on basis selection index comprising parameters age fi...

In this research, performance of portfolios formed by use of grid strategy based on new variables (aggressive, indifference and defensive stocks) presented by Rahnamaye Roodposhti (1388), and traditional ones (growth, growth-value and value stocks), calculated with Sharpe and Treynor performance measures and tested by an Active portfolio management approach to identify the portfolios by perform...
