まとめ
唇の動きで馬を飼育すると 軽度のストレスが発生し コルチゾールのレベルが上昇します ホッブルはよく耐えられるか 完全に拒絶された
科学分野:
- 馬の繁殖と福祉
- 動物の行動
- 獣医学
背景:
- 世界的に馬産業で手作業の繁殖は一般的です
- 馬の繁殖中の抑制方法による福祉への影響は,詳細な調査が必要である.
研究 の 目的:
- 唇のひっくり返しと足のひっくり返しで 雌馬のストレス反応を評価する.
- 抑止方法が雌馬の表情に影響するかどうかを判断する.
主な方法:
- 10匹の温血のメスと6匹のフランチェス・モンターゲンの交叉設計です
- ストレス指標として唾液コルチゾール,心拍数 (HR),心拍数変動 (HRV) の測定.
- 標準化されたテザリングと繁殖セッションでエトグラムを用いた行動評価.
主要な成果:
- 唾液中のコルチゾールの濃度が著しく上昇した (p=0. 04).
- 10匹の馬のうち2匹の馬はハブルの使用を許容できず,これは潜在的不耐性を示しています.
- ストレスの指標は測定されました.
結論:
- ハンドブリーディングの際のリップ・トゥイッチは,馬のストレスの軽い増加と関連しています.
- ホッブルは,メアによってよく許容されるか,全く許容されないかであり,個々の反応の多様性を示唆しています.
- 馬の繁殖における抑制方法の福祉への影響を完全に理解するには,より大きなサンプルサイズでのさらなる研究が必要です.

Exercise Stress Test

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Hypothalamic-Pituitary Axis
61.6K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Factors Influencing Heart Rate
4.1K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

Regulation of Heart Rates
2.2K
The regulation of heart rate is a complex process controlled by the autonomic nervous system (ANS), hormonal influences, and intrinsic cardiac mechanisms. The ANS has two main components: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Hormones of the Adrenal Glands
2.8K
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Physiological Foundation of Stress
157
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.
