Chitin is a natural polymer found abundantly in the shells of crustaceans, insects and in fungi. Chitin and its deacetylated product chitosan are commercially manufactured from shells of shrimp and crab. Four experimental diets containing 0 (control), 10, 25 and 50 mg/kg chitin were prepared in the laboratory from a commercial pellet diet. A total of 50 rainbow trout were divided randomly into ...

Saponins are naturally occurring amphiphilic molecules and have been associated with many biological activities. The aim of the present study was to investigate whether soya saponins trigger the onset of soyabean-induced enteritis in Atlantic salmon (Salmo salar L.), and to examine if dietary soya saponins increase the epithelial permeability of the distal intestine in Atlantic salmon. Seven ex...

The objective of this study was to investigate the hypoglycemic effects of quercetin (QE) in animal models of diabetes mellitus (DM). A starch solution (1 g/kg) with and without QE (100 mg/kg) or acarbose (40 mg/kg) was orally administered to streptozotocin (STZ)-induced diabetic rats after an overnight fast. Postprandial plasma glucose levels were measured and incremental areas under the respo...

The aim of this study was to evaluate the effects of eucalyptus leaf powder (ELP) and eucalyptus essential oil (EEO) on growth performance and immune response of broiler chickens. A total of 160 broiler chicks were assigned randomly into five dietary treatments from 7-42 days of age. Dietary treatments included: a control diet, control diets plus 1,000 or 3,000 mg/kg of ELP, and control diets p...

Pioglitazone hydrochloride (PIO), a peroxisome proliferator-activated receptor gamma (PPARγ) agonist, was administered orally for 85 weeks at 16 mg/kg/day to male rats fed either a diet containing 1.5% ammonium chloride (acid-forming diet) or a control diet to investigate the effects of urinary acidification induced by the acid-forming diet on the tumorigenic potential of PIO in the urinary bla...

The synergistic effects of dietary vitamin C and selenium (Se) on induced methylmercury (MeHg) toxicity in juvenile olive flounder Paralichthys olivaceus were examined in this study. Nine diets containing 3 different vitamin C levels (0, 200 and 400 mg kg diet in the form of L-ascorbyl-2-monophosphate), 3 different Se levels (0, 2 and 4 mg kg diet in the form of selenomethionine) at a constant ...

iron deficiency is the most common form of malnutrition in developing countries. iron containing supplements have been used effectively to solve this problem. in children, because of teeth staining after taking iron drops, parents have the idea that iron drops are the cause of tooth decay; therefore, they limit this vital supplement in their children's diet. hereby, we evaluate the histologic e...

We investigated the effects of dietary copper and vitamin E in diets containing 6% rapeseed oil on the performance and the antioxidative and oxidative status of growing pigs. The 10 dietary treatments consisted of a basal diet (9 mg of vitamin E/kg feed, 15 mg of Cu/kg feed), the basal diet + 6% rapeseed oil (Diet 1; 18 mg of vitamin E/kg feed, 15 mg of Cu/kg feed), and Diet 1 plus supplements ...

Rats were fed a purified diet containing either 1.5% sunflower oil [940 mg linoleic acid [18:2(n-6)]/100 g diet; 6 mg alpha-linolenic acid [18:3(n-3)]/300 g diet] or 1.9% soybean oil [940 mg 18:2(n-6)/100 g diet; 130 mg 18:3(n-3)/100 g diet]. In all cases and tissues examined 22:6(n-3) was lower and 22:5(n-6) was higher in rats fed sunflower oil than in rats fed soybean oil. Levels of 22:4(n-6)...
