概括

虚拟围 (VF) 技术有效地管理轮值放牧系统中的牛,而不会对动物福利或表现产生负面影响. 这种创新方法简化了劳动力,并增强了可持续的畜牧生产.

科学领域:

动物科学动物科学
农业技术农业技术
可持续的畜牧生产可持续的畜牧生产

背景情况:

动物福利对于可持续的畜牧业生产至关重要,放牧场可以提高牛群的福利.
轮换养殖管理虽然有利于福利,但由于高劳动力需求,它面临着采用障碍.
虚拟围 (VF) 为牧场管理和远程监控提供了一种不那么繁的替代方案.

研究的目的:

为了研究虚拟围 (VF) 的生理和性能影响,与肉牛小牛在轮转养下的物理电动围相比.
评估与VF技术相关的饮食消化能力,牲畜表现和压力反应 (便皮质醇代谢物).
为了评估牛的学习曲线和适应在轮值放牧系统中的VF线索.

主要方法:

一项为期8周的研究涉及32只分为四组的牛牛,在旋转放牧系统中使用VF和物理电.
监控 VF 暗示交互 (成功率和信心率) 和转换所需的时间.
评估草本质量,体重增加和便中皮质醇代谢物 (FCM) 度.

主要成果:

在两个放牧周期中,VF的成功率和适应性得到了改善,动物学会对听觉线索做出反应.
在VF和物理围组之间没有观察到压力指标 (FCM) 或体重增加的显著差异.
在VF群体中,动物进入新牧场所需的时间减少了,这表明有效的学习和管理.

结论:

虚拟围是一种可行的技术,可用于轮值放牧,与传统的物理围相比,它对牛的福利或表现没有不利影响.
通过减少劳动力需求并实现有效的牧场管理,VF技术有可能促进可持续的畜牧生产.
对各种放牧条件的VF系统进行进一步的研究是有必要的,以探索其在畜牧管理中的全部潜力.

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.

Stress Response System

Stress Response System

The stress response system, also known as the fight-or-flight response, is the body's automatic physiological reaction to perceived threats. Hans Selye introduced the concept of General Adaptation Syndrome (GAS) to describe the predictable pattern of changes that occur in response to stress. GAS consists of three sequential stages: alarm, resistance, and exhaustion. This model helps explain how chronic stress can contribute to health problems.
Alarm stage
In the alarm stage, the body's...

Stress Prevention and Stress Management Techniques IV

Stress Prevention and Stress Management Techniques IV

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...
