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...

This study evaluated the effects of Drinking Thyme Essence (DTE) (Zero, 0.10, 0.15 and 0.20 mL/L) on growth performance, immune response and changing of intestinal bacterial population in broiler chickens. A total number of 500 day old male broiler chicks (Ross 308), were randomly assigned to 4 treatments with 5 replicates and 25 chickens per each, based on a completely randomized design (CRD)....

The present study was carried out to determine the ability of Acipenser baerii in utilizing carbohydrate (dextrin) as a non protein energy source substituted with animal oil. A total of 65 juveniles A. baerii with an initial mean weight of 689 ± 62 g were distributed in 15 fiber glass tanks. Five diets were formulated including 0, 5, 10, 15 and 20% of dextrin and fed  for 8 weeks. Fish were wei...

A 50-day feeding trial was conducted to evaluate the effects of yeast nucleotide in diets on growth performance, serum immune indices and muscle composition of Ancherythroculter nigrocauda (mean initial body weight, 23.30±0.59 g). Seven isonitrogenous (approximately 42.76% crude protein) and isoenergetic (17.43 KJ g−1 gross energy) experimental diets with varying levels of yeast nucleotide (0[c...

The aim of this review is to provide an up-to-date summary of the evidence surrounding glycemic index (GI) and endurance performance. Athletes are commonly instructed to consume low-GI (LGI) carbohydrate (CHO) before exercise, but this recommendation appears to be based on the results of only a few studies, whereas others have found that the GI of CHO ingested before exercise has no impact on p...

MOTIVATION A common practice in biomarker discovery is to decide whether a large laboratory experiment should be carried out based on the results of a preliminary study on a small set of specimens. Consideration of the efficacy of this approach motivates the introduction of a probabilistic measure, for whether a classifier showing promising results in a small-sample preliminary study will perfo...

natural climatic conditions in urban areas can be changed by human physical environment. climate as a natural system and city as a human system have close mutual connections. urban population growth and consequent increase in urban physical expansion may lead to intensification in human activities and disturbances in the environment. this contributes to alterations in solar radiation, balance o...

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...
