Effect of diethylstilbestrol, ascorbic acid and vitamin E on serum lipid patterns
Poultry Science
|May 1, 1976
Summary
Diethylstilbestrol (DES) significantly increased lipid levels in chicken serum, particularly in hens. Cholestyramine effectively reduced cholesterol, while vitamin E and C supplementation modulated these effects, impacting fatty acid composition.
Area of Science:
- Biochemistry
- Animal Science
- Endocrinology
Background:
- Lipid metabolism is crucial for avian health and productivity.
- Diethylstilbestrol (DES) is a synthetic estrogen with known effects on animal physiology.
- Understanding the impact of dietary supplements and hormonal agents on lipid profiles is important for poultry science.
Purpose of the Study:
- To investigate the effects of diethylstilbestrol (DES), vitamins C and E, and cholestyramine on chicken serum lipid composition.
- To determine how combinations of these substances influence lipid profiles and fatty acid distribution.
- To assess potential interactions between hormonal treatment and nutritional supplementation.
Main Methods:
- Administration of DES, vitamins C and E, and cholestyramine to chickens, individually and in combination.
- Analysis of serum lipid levels, including triglycerides, phospholipids, and cholesterol.
- Gas chromatography and preparative Thin-Layer Chromatography (TLC) for detailed fatty acid composition analysis.
Main Results:
- DES injection significantly elevated serum triglycerides, phospholipids, and cholesterol, with a more pronounced effect in female chickens.
- Cholestyramine administration led to a substantial decrease in cholesterol levels, particularly in females.
- DES altered esterified fatty acid profiles, increasing oleic acid and decreasing stearic and linoleic acids; vitamin supplementation modulated these changes.
Conclusions:
- Diethylstilbestrol significantly impacts lipid metabolism in chickens, affecting overall lipid levels and fatty acid profiles.
- Cholestyramine demonstrates efficacy in reducing cholesterol in chickens.
- Combined vitamin and DES treatment can mitigate some of the lipogenic and fatty acid redistribution effects of DES.

01:20Lipid-Lowering Drugs: Statins and Miscellaneous Agents
Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...
01:18Lipids: Dietary Sources and Requirements
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
