A number of precautions were taken to ensure the accuracy of the analytical procedures and to avoid artifactual formation of N-nitroso compounds. NDPA (5 ng/g), an NDMA analog which is not normally present in the diets, was added to each powdered sample prior to the vacuum distillation step as an internal (recovery) standard. All reported levels of NDMA and NPYR have been adjusted for the recov...
Background and Objectives: Different diets have important roles in human health and aging. In the current study, we aimed to characterize the Klotho, an anti-aging protein, gene expression and protein level in the serum and assess the protein levels of Transforming growth factor-β and Platelet-derived growth factor in old rats which treated with different diets (high-fat, high-protein, low calo...
the speech act of disagreement has been one of the speech acts that has received the least attention in the field of pragmatics. this study investigates the ways power relations, social distance, formality of the context, gender, and language proficiency (for efl learners) influence disagreement and politeness strategies. the participants of the study were 200 male and female native persian s...
Abstract The aim of this research communication was to examine the effect dietary supplementation with wheat-based dried distillers’ grains solubles (DDGS), a by-product bioethanol production, on yield, composition, and fatty acid (FA) profile ewe milk. Forty-five purebred mid-lactating Chios ewes (average milk yield 2.23 kg/d in 96 ± 5 d lactation) were offered three iso-nitrogenous iso-energe...
In order to investigate the effect of phytase and copper supplementaion on growth and carcass composition of common carp (Cyprinus carpio L.), in a completely randomized design with 3 ×2 factorial arrangement with three replicates the experimental diets including three levels of phytase 0, 500 and 1000 (FYT) kg-1 and two levels of copper 0 and 15 mg/kg were tested. Diets contained 0.72 percent ...
One-hundred ninety-two crossbred steers (initial BW = 351 +/- 11 kg) were used to determine the effects of removing alfalfa hay (AH) from dry-rolled corn-based diets containing wet corn gluten feed (WCGF) on animal performance and nutrient (N and OM) mass balance in open feedlot pens. Steers were stratified by weight and assigned randomly to 24 pens (2 x 3 factorial) and fed for 132 d from June...
The objective of this study was to investigate the effects of diets containing different levels of milk thistle (0, 100 and 200 g/kg dry matter) and grains (barley and corn) with different rumen degradation rates on rumen bacteria and whole rumen microorganisms (WRM) of Khuzestan buffalo. The gas production (GP) technique, two steps digestion and specific bacteria culture medium methods were us...
this study was conducted to determine the effects of adding ethanol extract of propolis (eep) and cumin essential oil (ceo) to diets of broiler chicks on the performance, blood parameters, immune response and carcass traits. a total of 240 day-old ross-308 broiler chicks were randomly allocated to four treatments with six replicates and 10 birds in each replicate in a completely randomized desi...
The potential effects of dietary supplementation with ?-1,3 glucan and fructooligosaccharides (?-1,3 GF) on antioxidant activities, immunological response, growth performance Pacific white shrimp (Litopenaeus vannamei) was investigated. Four diets (iso-energetic iso-nitrogenous) different levels GF (0, 0.5, 1.0, 1.5 g kg?1) were fed to healthy juveniles weighing 3 ± 0.5 for 75 days. Shrimps ran...
