an experiment was conducted to evaluate the effect of fennel essence on performance, egg quality and ovarian morphology of commercial laying eggs for ten weeks. in this experiment, one hundred and forty 30-wk-old commercial egg laying type hy-line (w36) were randomly assigned into 4 treatments with 5 replicates and 8 birds per each. treatments were a control (0.0% essence) and diets containing ...

Salinity is an important abiotic stress factor that negatively affects plant growth and yield. The study, the effect of microbial fertilizer containing Bacillus subtilis bacteria, commercially named Subtima, on salt in pepper was observed. Two different saline solutions (100 mM 200 mM) were prepared to create growing medium. solution applied plants 4 concentrations (300, 400, 500 600 ppm) from ...

Olive waste cake (OWC) is underestimated as an agricultural waste. In this work, OWC extract were obtained by ethanol. Antioxidant efficacy of ethanolic OWC extract at levels of 100, 200, 400 and 600 ppm were studied. Samples of sunflower oil mixed with OWC extract were intermittent heated at 180±5°C for 4 hr / day, for 5 consecutive days and has been assayed for stabilization of sunflower oil ...

This study was conducted to evaluate the effects of lavender (Lavandula angustifolia)extract as an alternative to flavophospholipol on performance, carcass characteristics, antioxidant status,meat quality, intestinal morphology and ileal microflora of broilers. A total of 220 day-old male broiler chicks (Ross 308) were used in a completely randomized design with five treatments each re...

background: trypsin modulating oostatic factor (tmof) terminates trypsin biosynthesis in adult and larval mos­quito gut. it will inhibit the growth and development of mosquito larvae feeding on it resulting in death by starvation. the objective of this study is to determine the effective dose of pichia-tmof and the combination of pichia-tmof with bacillus thuringiensi s ( bt) as larvicide on ae...

A bioassay of azobenzene for possible carcinogenicity was conducted by administering the test chemical in feed to F344 rats and B6C3F1 mice. Groups of 50 rats of each sex were administered azobenzene at one of two doses, either 200 or 400 ppm, for 105 or 106 weeks. Matched controls consisted of 20 untreated rats of each sex. All surviving rats were killed at the end of administration of the tes...

The acute toxicity of ethylene glycol monopropyl ether (EGPE) and ethylene glycol monopropyl ether acetate (EGPEA) was determined in a series of standardized tests. The oral LD50 in rats was 3089 and 9456 mg/kg EGPE and EGPEA, respectively. Skin irritation was slight following an occluded single dose application of either compound to the guinea pig abdomen. The dermal LD50 for guinea pigs was 1...

background & aim:  the aim of this study was to assess the bactericidal effect of three medicinal plant species, including thymus vulgaris, trachyspermum ammi, and mentha aquatica on erwinia carotovora growth. experimental: this research was done in a factorial to completely randomized design with three concentrations, and three replicates on nutrient agar culture medium. results &discu...

To evaluate the effects of anesthesia with different concentrations of clove extract (0, 50, 200, 400 and 600 mg) on sperm function and some hematological parameters in Prussian carp, Carassius gibelio (Bloch, 1782), 30 mature male were examined. In this purpose, sperm motility traits and some hematological parameters ( Red blood cell count (RBC), hemoglobin concentration (Hb), hematocrit (PCV)...
