this experiment was conducted to study the effect of dietary n-3 to n-6 ratio on performance, immune response, blood parameters and fatty acids profile of broiler chickens. a total number of 192 one day old broiler chicks were randomly alloctted into 6 groups. chicks of groups 1, 2, 3, 4, 5 and 6 were fed balanced corn-soybean diets containing n-3 to n-6 ratios of 1:1, 1:3, 1:5, 1:7, 1:9 and 1:...

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...

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...
