the study was conducted to evaluate the effects of different dietary oil sources supplementation on laying hens’ performance and fatty acids profile of egg yolks. seventy-two 23-week-old laying hens (tetra-sl) divided into six experimental diets (four replicates and three birds per replication) in a completely randomized design for nine weeks. experimental diets were included: 1) control (no oi...

fish oil is the important fat source in fish nutrition. high demand for fish oil and low global supply arise a need of alternative oils in fish culture. plant oils are a good candidate in this case. the aim of the present study was to compare the efficacy of fish oil and linseed oil on growth and stress resistance of tiger barb ( puntius tetrazona ) larvae. artemia nauplii were enriched by 2.5,...

despite the increased emphasis on chronic non-communicable diseases, there are notable deficits about nutrition education in many medicine training programs particularly gastroenterology fellowship programs. in the present cross-sectional study, we examined the nutritional knowledge related to clinical nutrition among iranian gastroenterology fellows. thirty-six gastroenterology fellows current...

Metabolites resulting from nitrogen metabolism in yeast are currently found in some fermented beverages such as wine and beer. Their study has recently attracted the attention of researchers. Some metabolites derived from aromatic amino acids are bioactive compounds that can behave as hormones or even mimic their role in humans and may also act as regulators in yeast. Although the metabolic pat...

the nutrients are able to interact with molecular mechanisms and modulate the physiological functions in the body. the nutri­tional genomics focuses on the interaction between bioactive food components and the genome, which includes nutrigenet­ics and nutrigenomics. the influence of nutrients on f genes expression is called nutrigenomics, while the heterogene­ous response of gene variants to nu...

results a relatively strong positive correlation was found between the knowledge development approach, nutritional science, nutrition education and research, and proper solutions for individual nutritional problems and a culture of nutrition (p < 0.001). conclusions 1) effective enhancement and participation in an academic community will be important in the future of food and nutrition security...

Each species of intestinal bacteria requires a nutritional source to maintain its population in the intestine. Dietary factors are considered to be major nutrients; however, evidence directly explaining the in situ utilization of dietary factors is limited. Microscale bacterial distribution would provide clues to understand bacterial lifestyle and nutrient utilization. However, the detailed bac...

Sweet lupin (Lupinus albus ), a protein-rich legume devoid of anti-nutritional factors, is considered to have a high potential for protein nutrition in man. Results concerning the nutritional value of lupin protein are, however, conflicting in animals and very scarce in human subjects. Furthermore, where fibre-rich protein sources are concerned, the long-term nutritional results are often obscu...
