概括
在反动物的饮食中加入棕核蛋糕会对牛,山羊和绵羊的营养利用和表现产生不同的影响. 原蛋白利用率保持一致,但其他营养摄入量和动物表现因棕核蛋糕水平而异.
科学领域:
- 动物科学动物科学
- 营养生物化学 营养生物化学
- 类动物营养 类动物营养
背景情况:
- 棕核蛋糕 (PKC) 是反动物的替代性料.
- 了解其对营养利用和性能的影响对于可持续的畜牧业生产至关重要.
- 对食成分的特定物种反应需要详细的研究.
研究的目的:
- 以元分析的方式探索棕核蛋糕含量水平 (PKC) 和营养利用之间的关系.
- 评估PKCInclusion对被关押的牛,山羊和绵羊的表现的影响.
- 为优化PKC在反动物食中的使用提供数据.
主要方法:
- 使用PRISMA协议进行的51项研究的元分析.
- 混合效应模型分析PKCInclusion和干物质 (DM),原蛋白 (CP),以太提取物 (EE),中性清洁剂纤维 (NDF),总可消化的营养素 (TDN),平均每日增益 (ADG) 和料效率 (FE) 之间的关系.
- 种类和研究分别被认为是固定和随机效应.
主要成果:
- 发现了EE和TDN摄入量/消化能力与PKC包括之间跨物种的独立关系.
- 在反动物物种之间,CP摄入量与消化率的关系没有差异.
- 牛和山羊/羊之间的DM和NDF摄入模式有所不同,而山羊和牛/羊之间的料效率有显著差异. 在不同物种中,ADG的降低也类似.
结论:
- 在受限牛,山羊和绵羊中,PKC包含对DM和营养摄入/消化能力有不同的影响,CP是例外.
- 像料效率和平均每日增益这样的性能指标显示了对PKC纳入的特定物种反应.
- 这些发现可以为营养模型提供信息,以便在生产性反动物中更好地利用PKC.

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
