in the present study, effects of iron excess treatments (0, 250, 500 mg l-1) were evaluated in four rice varieties including shafagh, khazar, hashemi and sadri in pot condition. afterward, effects of iron excess (10 and 250 mg l-1) were further investigated in the most resistant variety (shafagh) in sand culture with yoshida nutrient solution. this experiment was arranged as factorial in rcbd w...

low-fat butter is water in oil emulsion comprising a continuous fat phase including butter, emulsifiers and colorants and also a dispersed aqueous phase including water, stabilizers and proteins. in this research, by using protein components especially full-fat soy flour, a product were produced which has extreme similarity to ordinary butter and also has good organoleptic properties. water : b...

chrysanthemum cut flower is not sensitive to ethylene and its vase life depends on vascular blockage. in order to evaluating of effect of antibiotics and essential oils on the vase life and quality characteristics of chrysanthemum cut flower an experiment carried out based on a rcd with 10 treatments: artemisia at 3 levels (10, 30 and 50 %), amoxicillin at 3 levels (100, 200 and 300 mg l-1), ri...

this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...

proteins are fundamental components of cells which mediate many essential biological processes. proteomics is a rapidly growing field for the study of proteome, the protein complement expressed by the genome of an organism or cell type. the large-scale analysis of proteins leads to a more comprehensive view of molecular and cellular pathways that improves the overall understanding of the comple...

Reducing dietary protein content in fish feeds will reduce cost of production if growth performance can be maintained. In this study, we assessed the effects of reduced dietary protein content from 33.5% to 27.4% with ideal amino acids profile on the growth, immune parameters, intestinal microvilli length and total ammonia nitrogen discharge of tilapia. After 8 weeks of feeding, growth performa...
