まとめ
ニンニクのエッセンシャルオイル (GAR) は,微生物の機能に悪影響を及ぼさずに,の発酵におけるメタン生成を効果的に減少させた. この研究は,GARARを強調しています.
科学分野:
- リュームの微生物学
- 動物の栄養 動物の栄養
- 自然製品化学とは
背景:
- rumen のメタノゲネシスは,温室効果ガスの排出に寄与する.
- エッセンシャルオイル (EOs) は, rumenの機能を調節し,メタン (CH4) の生産を減らすために調査されています.
- EOの有効性は,化学的構造と含有量の影響を受けます.
研究 の 目的:
- rumen methanogenesisを抑制する9つの選択されたEOの有効性を評価する.
- rumen発酵のパラメータとCH4の生産に対するEOの影響を in vitroで評価する.
- EOの化学組成と用量の,そのアンチメハノゲン効果に対する影響を決定する.
主な方法:
- In vitroバッチカルチャー発酵アッセイは24時間で行われました.
- 9つのEO (シナモン,ラベンダー,ガーリック (GAR),レモングラス (LEG),ペッパーミント (PPM),ユーカリ,コリアンダー,オレガノ,ジンジャー (GIN)) は,指定された低および高用量でテストされました.
- 流体からブッファーの混合物と,飼料から濃縮物への基板を使用し,発酵パラメータとガス/CH4生産の測定を行いました.
主要な成果:
- すべてのEO処理は,発酵パラメータに有意な影響を及ぼしました (p <0.01).
- ほとんどのEOは,投与量により異なる量の合計ガス生産とCH4排出量を減少させました.
- ガーリックEO (GAR) は,特に低用量では,好ましい発酵を維持しながら,CH4を最大限抑制することが示されましたが,高用量では発酵抑制を引き起こすいくつかのテルペノイドEOとは違います.
結論:
- メタンの軽減のためのエッセンシャルオイルの有効性は,化学組成と含有レベルに大きく依存しています.
- 硫黄ベースのバイオアクティブに富むニンニクEO (GAR) は,インビトロCH4減少において最も有望な結果を示しました.
- 持続可能な畜産のために,GARのようなEOの実用的な応用を確認するために,さらにin vivoの検証が必要である.

Most eukaryotic organisms require oxygen to survive and function adequately. Such organisms produce large amounts of energy during aerobic respiration by metabolizing glucose and oxygen into carbon dioxide and water. However, most eukaryotes can generate some energy in the absence of oxygen by anaerobic metabolism.
Fermentation is a type of metabolic process that occurs in the absence of oxygen, where organic molecules such as glucose are broken down to produce energy. During this process, the...

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...

Impact

Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...
