Selenium, a trace mineral complement is used as cofactor of antioxidant enzymes that protects fishes against environmental stress agents and enhances performance in fishes. In this study the different levels of organic and inorganic source of  selenium were included in juvenile rainbow trout diet to evaluate feed conversion ratio (FCR), specific growth rate (SGR), weight gain percent (WG), cond...

An experiment was conducted to evaluate the effects of a restriction to home-grown feedstuffs and abstinence from supplementation with synthetic amino acids (AA), as ideal objectives in organic pig production according to the IFOAM standards, on growth performance and carcass characteristics. One hundred individually housed pigs were allocated to four dietary treatments and fed from growing thr...

the main purpose of this study was to investigate the effects of euphorbia hirta and acidifiers supplement on resistance of broiler chickens against salmonella enteritidis infection. a total of 120 day-old male broiler chicks were randomly assigned to 3 dietary treatments. 1) basal diet, 2) basal diet supplemented with 2 g/kg organic acid (oa) and 3) basal diet supplemented with 7.5 g/kg e. hir...

SHERMAN and PAPPENHEIMER [1921] and later, Pappenheimer, McCann, Zucker and Hess [1921] induced the development of severe experimental rickets in rats by a diet (No. 84) consisting of 95 % patent flour and 5 % salt mixture. This diet was not only deficient in phosphorus and fat-soluble A, but was also very obviously deficient in many other respects. McCollum, Simmonds, Shipley and Park [1921], ...

The objective of this study was to determine the effect of dietary selenium source on the growth and development of turkey embryos, and egg hatchability. White broad-breasted BUT Big 6 turkeys (1800 females and 150 males) were placed under optimum management conditions. Turkey diets were supplemented with organic selenium, and in the other with inorganic selenium, in the amount of 0.3 ppm. Eggs...

Recent research results indicate that organic consumers have a healthier diet than other consumers. This suggests that there might be a positive relationship between organic consumption and a healthy lifestyle. One aim of an ongoing research project is to analyse whether consumers with a high organic consumption have a higher interest in nutrition and a healthy living than other consumers. In o...

The main purpose of this study was to investigate the effects of Euphorbia hirta and acidifiers supplement on resistance of broiler chickens against Salmonella enteritidis infection. A total of 120 day-old male broiler chicks were randomly assigned to 3 dietary treatments. 1) basal diet, 2) basal diet supplemented with 2 g/kg organic acid (OA) and 3) basal diet supplemented with 7.5 g/kg E. hir...

The contribution of diet to cancer ranges from 10 to 80%. The low ingestion of antioxidants and enzymatic cofactors involved in DNA repair and methylation reactions and the high ingestion of chemical additives present in the modern diet, associated with genetic factors, could lead to genomic instability and the hypomethylation of proto-oncogenes, thus contributing to development of genetic-rela...

The goal of this article was to compare the effects of a prolonged use of organic and transgenic soy on the lipid profile and ovary and uterus morphology. Wistar rats were fed three different diets from weaning until sacrifice at 15 months of age. The three diets were: casein-based diet control group (CG), organic soy-based diet group (OSG), or transgenic soy-based diet group (GMSG). There were...
