概括

发酵大豆谷物 (FSBG) 可以代替标准大豆谷物在养羊的食中. 无菌毒素的FSBG在体内没有对动物的表现或营养物质消化能力产生负面影响.

科学领域:

动物营养动物营养
料科学料科学
农业化学农业化学

背景情况:

发酵大豆谷物 (FSBG) 经常被认为不适合用于动物料,原因是假定的组成变化和真菌毒素风险.
现有的化学成分数据并不完全支持这些担忧,而且缺乏体内研究.

研究的目的:

调查使用发酵大豆谷物 (FSBG) 作为料羊食中的蛋白质来源的影响.
评估FSBG取代标准大豆谷物 (SSBG) 的营养价值和动物表现.

主要方法:

分析了两种类型的FSBG (部分和完全发酵) 和SSBG的化学成分.
在试验室测试干物质消化性 (IVDMD) 和乳头可降解性.
料区的羔羊被食FSBG,完全取代SSBG (17.4%的干物质),以评估营养摄入量,消化能力和性能.

主要成果:

完全发酵的大豆谷物 (CFSBG) 的干物质和碳水化合物含量较低,但比SSBG更高的原始蛋白质,纤维和难以消化的NDF.
在单独评估时,FSBG与SSBG相比,在体外干物质消化率 (IVDMD) 和乳头可降解蛋白质较低.
然而,当将FSBG替代物纳入饮食时,它没有影响整体IVDMD,营养摄入量,明显的消化能力或羔羊的表现 (平均每日增益,尸体增益).

结论:

无菌毒素发酵大豆粒 (FSBG) 是一个可行的替代蛋白质来源,用于养羊的食.
FSBG可以完全取代标准大豆谷物 (SSBG),而不会影响动物的表现或营养利用.

Overview of Metabolism

Overview of Metabolism

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...

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
