the effect of different levels of dried purslane powder (dpp) in broiler diets on performance, immune response and some of blood factors was studied with 160 one day old chicken ross 308 in a completely randomized design with four treatments (diets included with levels zero (control), 2.5, 5 and 7.5 percent dpp), four replicates and 10 chicks in each replication. at 22-42 and 1-42 days differen...
in order to determine the optimal levels of energy and protein in grower diet of japanese quail, 360 dayold japanese quails were used in a 3×3 factorial arrangement of dietary treatments that comprised threelevels of metabolisable energy (2750, 2850, and 2950 kcal/kg) and three levels of crude protein (24, 26and 28 percent) with four replicates per treatment in a completely randomized design. f...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Previous studies indicated the positive impact of dietary supplementation of arginine on meat quality and growth, though there is no report regarding the effect of in ovo injection of arginine on meat quality. So, the aim of this study was to evaluate the effect of in ovo injection of different levels of L-arginine on hatchability, growth performance, and meat quality of Ross 308 broiler ch...
The present study was conducted to determine the effect of saffron petal powder on the growth and activity of antioxidant enzymes in the grass carp larva (Ctenopharyngodon idella). Fish larva (0.75 ± 0.03 g and 4.39± 0.09 cm) were fed separately with four levels of saffron petal powder diets which were included; P0 (0%), P1 (2%), P2 (4%) and P3 (6%) for 60 days. One thousand two hundred fish we...
in order to investigate effects of partial replacement of starch with neutral detergent soluble fiber (ndsf) on weekly weight gain, feed intake, feed conversion ratio, digestibility and some histopathological changes of rumen, 16 lambs were used in completely randomized design. the experimental period was 70 days. dietary treatments were 1- control (high starch), 2- beet pulp, 18 percent, 3- be...
This experiment was conducted to determine the phosphorus relative bioavailability of eight samples of dicalcium phosphate. Bioavailability of Samples of dicalcium phosphate was evaluated and their effects on performance of laying hens were investigated. Commercial samples of Dicalcium Phosphate were provided from the following manufacturers: Iran Phosphate, Partove Bashash, Godaze, Poya Khojas...

This experiment was conducted to investigate the effects of egg yolk and soybean oil as early feeding to broiler chicks on growth performance and intestinal morphology. A number of 525 chicks (Ross 308) were allocated to 7 treatments with 5 replicates and 15 birds in each replicate in a completely randomized design. Treatments were: control group (without early feeding), and feeding of 0.4 and ...
the effect of lavender essential oil (leo) on broiler performance, carcass characteristics and blood metabolites was examined in a completely randomized design with 5 treatments (control diet, virginiamycin 10% (50 ppm) and 3 diets containing 150, 250, 350 ppm lavender essential oil) and 5 replications in a period of 42-days. no significant differences were noticed for feed intake between the t...
