The objective of this study was to evaluate production response and more specifically percentage and yield of fat in milk from dairy cows fed distillers grains with added solubles (DGS). It was hypothesized that the oil present in DGS would decrease milk fat yield. Four dietary treatments consisted of dried DGS replacing soybean meal and soybean hulls. The DGS inclusion rates as a percentage of...

Male Fisher 344 rats were fed diets containing either 20% corn oil, 20% coconut oil or 18% coconut oil plus 2% corn oil for 3 wk. A single dose of [3H]aflatoxin B1 [(3H]AFB1) was administered ip and the biliary excretion of aflatoxin metabolites and the binding of 3H to nucleic acids were studied. In other experiments the in vitro metabolism of AFB1 by liver postmitochondrial supernatants prepa...

BACKGROUND Olive oil is the main source of dietary lipids in most Mediterranean countries where mortality and incidence rates for coronary heart disease (CHD) are the lowest in Europe. Although international comparisons and mechanistic reasons support the hypothesis that a high olive oil intake may prevent CHD, limited data from studies of individuals are available. METHODS A hospital-based c...

BACKGROUND/OBJECTIVES The aim of this research was to study the different long term effects of consumption of dietary oil sources with varying omega-6/omega-3 (ω-6/ω-3) polyunsaturated fatty acids (PUFAs) ratios on bone marrow fatty acid level, ex vivo prostaglandin E2 (PGE2) release, and mineral content of bone in rabbits. MATERIALS/METHODS For this purpose, weaning and female New Zealand wh...

This study was done to identify the effects of dietary safflower oil or soybean oil on the milk composition of maternal rats and the tissue fatty acid composition in postnatal rats. Different types of dietary fats affected the fatty acid pattern in the dam's milk. They affected tissue weight, lipid content, and phospholipid fatty acid compositions in the liver and brain of young rats, showing a...

Many people take dietary supplements, but information on characteristics associated with their use is lacking. The relationship between lifestyle behaviours, morbidity and use of dietary supplements has not been examined and earlier studies have limited applicability to a general population. These issues were addressed in the current study. Information was obtained by postal questionnaire sent ...

The objective of this study was to compare effects of dietary polyunsaturated fatty acid supplementation (corn oil or fish oil) on selected immune responses in normal horses. Two groups of horses (n = 5) were randomly assigned a dietary supplement with either 3.0% corn oil or fish oil for a period of 14 weeks. Plasma fatty acid profiles were monitored to ensure uptake of dietary fatty acids. Ce...

The influence of dietary oxidized oil was studied on laying hen performance, egg quality and blood metabolites.  Experiment was conducted on 160 laying hens (Hy-Line W-36, 54-61 wk of age) in a completely randomized design with five treatments and four replicated cages containing eight birds per cage. Dietary treatments replaced fresh soybean oil in the control diet (3% fresh soybean oil, 15.25...

objectives the link between dietary fat and heart disease has been established for decades. although, the atherogenic effect of saturated fatty acids is somehow controversial, the cardioprotective effects of polyunsaturated fatty acids (pufa) are clearly documented. this study investigated the effects of different dietary oils on serum fatty acid composition in rat. methods six week male wistar...

The mechanism by which dietary unsaturated fatty acids lower low density lipoprotein (LDL) cholesterol is unknown. Unsaturated fatty acids incorporated into the cell membrane can increase membrane fluidity and, as a result, dramatically alter membrane-dependent cell functions. Therefore, we examined the effect of long-term dietary consumption of corn oil and coconut oil with and without cholest...
