概括

富含的海刺废物可以替代石在产母的食中. 这提高了动物福利和蛋厚度,而不影响蛋质量或骨强度,促进循环经济原则.

科学领域:

动物营养和料科学动物营养和料科学
循环经济和废物回收利用
海洋资源管理海洋资源管理

背景情况:

在地中海每年大量捕捞海会产生大量的骨废物.
海刺的废物富含和,具有潜在的抗氧化特性.
目前的做法导致资源的过度消耗,突出了可持续替代品的需要.

研究的目的:

为了评估海刺废物的有效性,作为产卵母的食中的来源.
评估这种替代对蛋生产,质量和动物福利的影响.
在循环经济框架内探索回收海洋废物的潜力.

主要方法:

两组产卵母被食或控制饮食 (石灰岩衍生的) 或实验饮食 (海废物).
评估的关键参数包括蛋产量,蛋质量 (厚,重量,强度),骨折强度和动物福利指标.
还分析了饮食中的抗氧化活性和胡卜素含量.

主要成果:

两组之间没有观察到卵产量,蛋重量,破裂强度或蛋黄颜色的显著差异.
被养的海废弃物显示了动物福利的改善 (病变更少) 和显著更厚的蛋.
骨的折断强度没有受到影响,这证实了来自海废物的的生物可用性.

结论:

海的废物是一种可行的,可持续的替代品,用于产母的食.
替代对动物福利和蛋的完整性产生积极影响,而不会影响整个蛋的质量.
这种方法通过利用海洋废物流来支持循环经济原则.

Comparative Excretory Systems

Comparative Excretory Systems

Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.

Skeleton and Calcium Homeostasis

Skeleton and Calcium Homeostasis

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.
