this experiment was conducted in order to determine the effects of different dietary growth promoters on growth performance and nutrient digestibility in male broiler chickens. a total of 360 male broiler chicks (day-old ross 308 strain) were distributed into a completely randomized design (crd) having 6 dietary treatments with four replicates and 15 birds in each replicate. experimental treatm...

abstract  introduction: this experiment was conducted to study the effects of different levels of flaxseed (0, 5, 10 and 15% of diet) and copper (in the form of cupric sulfate pentahydrate, 0 and 250 ppm of diet) on fatty acids and cholesterol in egg yolk of laying hens. methods: a total of 128 white leghorn layers aged 50 weeks were used in a factorial design and randomly assigned to 8 treatme...

Diets rich in polyunsaturated fatty acids lower plasma HDL cholesterol concentrations when compared to diets rich in saturated fatty acids. We investigated the mechanistic basis for this effect in the hamster and sought to determine whether reduced plasma HDL cholesterol concentrations resulting from a high polyunsaturated fat diet are associated with a decrease in reverse cholesterol transport...

BACKGROUND The objectives of this study were to investigate the effects of persimmon peel (PPM) supplementation on carcass performance, pork quality, eating quality, fatty acid composition, and cholesterol concentration of the porcine longissimus dorsi muscle. RESULTS No adverse effects of PPM supplementation were observed on carcass and meat quality characteristics among the treatment groups...

AIM To evaluate the influence of dietary lipid quality on the body mass, carbohydrate metabolism and morphology of the rat ventral prostate. MATERIALS AND METHODS Wistar rats were divided into four groups: SC (standard chow), HF-S (high-fat diet rich in saturated fatty acids), HF-P (high-fat diet rich in polyunsaturated fatty acids) and HF-SP (high-fat diet rich in saturated and polyunsaturat...

Increasing the energy value of diets with dietary fat, particularly fats rich in saturated fatty acids, can result in the elevation of plasma total and lipoprotein cholesterol. In the present study, experimental diets were designed to examine the effects of increasing the energy content of diets with a saturated fat source and cholesterol in a non-purified diet on hyperlipoproteinaemia and aort...

This study was designed to investigate the effects of three diets with different levels of trans fatty acids and the physiologic status on the physicochemical properties and enzymatic activities of liver microsomes and mitochondria. Three groups of 10 female weaning rats each were fed for 10 wk one of three diets differing in their trans fatty acid contents (Control, 0 mol/100 mol total fatty a...

The present study was designed to examine whether the hipocholesterolemic effect of L-carnitine supplementation is related with lipoprotein fatty acid metabolism. Fatty acid compositional and cholesterol content changes were measured in lipoproteins of six different groups of rabbits. Group 1, rabbits fed a standard diet; group 2, rabbits fed standard diet plus L-carnitine 80 mg/kg bw; group 3,...

in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...
