概括

将香精油 (OEO) 或素添加到蛋白质能量补充剂并没有改善Nellore牛在推迟的Urochloa brizantha牧场上的表现. 这些添加剂没有观察到显著的体重增加,每日增加或生产力.

科学领域:

动物科学动物科学
类动物营养类动物营养
飼料利用飼料利用飼料利用

背景情况:

延迟放牧系统对于在干旱季节维持牛的营养至关重要.
补充策略旨在提高牧场上的动物表现和生产力.
Oregano 精油 (OEO) 和 monensin 正在作为牛料添加剂进行研究.

研究的目的:

评估香精油 (OEO) 和素补充剂对内罗尔牛的表现的影响.
为了评估这些添加剂对放缓放牧Urochloa brizantha"Marandu"牧场的动物的影响.
为了确定OEO或monensin是否提高了动物的表现或每面积的生产力.

主要方法:

一个完全随机的设计,使用24头Nellore牛 (209公斤平均体重). 超过12个场.
四种治疗方法:对照组,蒙宁素 (60毫克/公斤补充剂),OEO3 (3克/动物/天) 和OEO6 (6克/动物/天).
在三个28天的放牧周期中,提供了84天的补充剂;动物表现和料可用性被测量.

主要成果:

添加剂和放牧周期对料变量或动物表现 (体重增加,每日增加,养率) 没有显著的相互作用.
在第三个放牧周期 (P <0.05) 中,观察到动物表现下降和养殖率增加.
与对照组相比, Oregano 精油和monensin 没有产生额外的性能或生产力增长.

结论:

Oregano 精油和 monensin 补充剂并没有改善Nellore牛在延迟的Urochloa brizantha牧场上的表现.
仅仅蛋白质能量补充剂在与OEO或monensin补充时并没有产生性能益处.
可能需要进一步的研究来探索延迟放牧系统的替代添加剂或管理策略.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

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...

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
