this study was conducted to investigate the effects of artichoke powder on performance and immune function of japanese quails poisoned with carbon tetrachloride (ccl4). one hundred meat type (1-d-old) quails were assigned randomly to 4 treatment groups (n=25). treatment groups included with the study were: 1) control group (without artichoke supplementation or ccl4 administration, 2) group with...

this study was conducted to evaluate the effects of in ovo feeding of different nutrients on hatchability, initial weight after hatch, growth performance, blood parameters, immune organs and intestinal morphology of broiler chicks. the experiment was conducted in a completely randomized design with 5 treatments, 3 replicates and 16 fertile eggs from ross 308 breeders (28 week old) in each repli...

We tested the hypothesis that ascorbic acid in the diet of rats lowers the concentration of soluble Cu in the small intestine, causing a decrease in apparent Cu absorption. Male rats were fed on diets adequate in Cu (5 mg Cu/kg) without or with 10 g ascorbic acid/kg. The diet with ascorbic acid was fed for either 6 or 42 d. Ascorbic acid depressed tissue Cu concentrations after a feeding period...

In a 42-d experiment, 576 one-day-old Vencobb 308 broiler chicks were used to investigate the effects of lecithin extract (0.5 g/kg), choline chloride 60% (1 g/kg) and Bio choline (1 g/kg) in diets of moderate and high energy in a 4 × 2 factorial arrangement on performance and certain physiological traits in broiler chickens. The inclusion of Bio choline and lecithin extract in the diet signifi...

In commercial production, chickens are subjected to feed withdrawal prior to slaughter and exposed to stress during transport and handling of the animals at the slaughterhouse; this causes plasma glucose and glycogen stores in liver and muscle to decrease, which has a negative impact on meat quality. The aim of the present study was to investigate how supplementation of the energy complements c...

A study was conducted to determine the effects of adherent Lactobacillus culture on growth performance, intestinal microbial population, and serum cholesterol level of broilers. Four dietary treatments, consisting of the basal diet (control), basal diet + 0.05, 0.10, or 0.15% Lactobacillus culture (LC), were fed to 2,000 Arbor Acres broiler chicks from 1 to 42 d of age (DOA). The chicks were ra...

The antimicrobial effectiveness of different extracts of Chicory (Cichorium intybus L.) plant including methanolic, ethylic acetate, chloroformic, and aqueous extracts was evaluated by Disk Diffusion method. The ethylic acetate extract showed higher antibacterial activity against E. coli compared with others. Then, effects of different levels of ethylic acetate extract on growth performance and...

The ability of aquatic bacteria Pseudomonas fluorescens SSD (Ps-D) and Pseudomonas putida SSC (Ps-C) to support the persistence of Legionella pneumophila (Lp-1) in an artificial water microcosm was investigated for 42 day, at two different incubation temperatures. At 4 degrees C, individually suspended Lp-1 was no longer detectable just after 24 hours, while in co-cultures with Pseudomonas, Lp1...

feed restriction strategies are proven to be effective in increasing the growth performance and carcass parameters of broiler chickens. the objective of the present experiment was to evaluate the effects of feedremoval for three hour time periodon growth performance and carcass parameters of relatively older male broiler chickens. twenty days old male broiler chickens (n=80) were allocated into...
