まとめ
コレカルシフェロール (ビタミンD3) または25-ヒドロキシビタミンD3の栄養補給により,卵殻と骨の質が改善されました. 25- ヒドロキシビタミンD3は,ビタミンD3に比べ,骨の形成と質を向上させるのにより有効であることが示された.
科学分野:
- 動物の栄養
- 鶏肉科学
- 栄養学的生化学
背景:
- 産卵中のアヒルの老化は 卵殻や骨の質を損なう可能性があります
- ビタミンD3とその代謝物質25-ヒドロキシビタミンD3は,カルシウムとリン代謝に不可欠です.
- ビタミンDの補給を最適化することは 生産性と養鶏の福祉を維持するために不可欠です
研究 の 目的:
- 食事中のコレカルシフェロール (ビタミンD3) と25-ヒドロキシビタミンD3が,卵殻と老いた産卵アヒルの骨質に与える影響を評価する.
- ビタミンD3と25-ヒドロキシビタミンD3の骨格の整合性と卵の特性を改善する効果を比較する.
主な方法:
- 792匹のロングヤンの産卵アヒルを 16週間にわたって飼育した実験.
- ビタミンD3または25-ヒドロキシビタミンD3 (800〜4000IU/kg) の食生活レベルを変化させる.
- 卵殻の物理的および超構造的特性,血のミネラルおよびホルモンレベル,骨のミネラル含量および強度,およびカルシウム輸送と骨形成に関連する遺伝子発現の評価.
主要な成果:
- ビタミンD3と25-ヒドロキシビタミンD3の両方のサプリメントは,卵殻の厚さ,重量,超構造を大幅に改善しました.
- 25ヒドロキシビタミンD3は,卵殻のカルシウム含有量を顕著に増加させ,乳毛層の割合を減少させた.
- 両方の形態は血のリンと1,25- 二酸化炭素ビタミンD3を増加させ,25- 二酸化炭素ビタミンD3は血のカルシウムを増加させ,骨形成マーカーと遺伝子発現を改善した.
- 25ヒドロキシビタミンD3は,ビタミンD3と比較して,骨の質と形成に優れた効果を示した.
結論:
- ビタミンD3と25-ヒドロキシビタミンD3を摂取すると,卵殻と骨の質が改善されます.
- 25-ヒドロキシビタミンD3は,ビタミンD3よりも骨の形成と質を促進します.
- 両方のサプリメントは 卵殻の質の改善に類似した効果があります

Role of Skin in Vitamin D Synthesis
5.6K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Role of Vitamins in Maintaining Bone Health
3.6K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Bone Disorders
3.9K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Skeleton and Calcium Homeostasis
4.8K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Lipids: Dietary Sources and Requirements
1.0K
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...

Essential Minerals for Bone Health
4.4K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
