概括

积极的人际接触和对小猪的丰富住房改善了早期的福利和应激适应能力. 虽然积极的相互作用提高了小猪的福祉,但生育箱没有对断奶后的应激弹性产生负面影响.

科学领域:

动物科学动物科学
动物福利动物福利
伦理学伦理学伦理学

背景情况:

早期的生活经历显著影响动物的长期应激适应能力.
本研究研究了早期人类接触和住房环境对小猪应激应对机制的综合影响.

研究的目的:

确定早期积极的人际接触和不同生育住房系统对小猪福利和应激弹性的影响.
评估这些早期经验对猪应对一般环境的能力的长期影响.

主要方法:

一个2x2的因数设计被采用了48个子的猪.
治疗包括生育箱 (FC) 与松散 (LP;PigSAFE) 住房以及常规接触 (C) 与常规加上积极的人际接触 (+HC).
测量包括血清脑衍生神经营养因子 (BDNF),损伤,皮质醇,免疫球蛋白-A,行为,以及断奶前后的生长.

主要成果:

与常规接触 (C) 猪相比,积极的人际接触 (+HC) 猪在断奶前的伤害较少.
与生育箱 (FC) 猪相比,宽松 (LP) 猪在哺乳期间表现出更多的游戏行为和互动,与少重复的鼻,在哺乳期间.
在FC先养的C猪中,血清BDNF度较低;LP小猪具有更高的撕裂染色,可能与更高的生长率有关.

结论:

积极的人际交互和丰富的松散住房积极影响幼猪的福利和早期生活中的应激适应能力.
虽然生育箱限制了行为机会,但它们似乎不会对猪的福利或断奶后的应激弹性产生负面影响.
需要进一步的研究来将这些发现泛化到不同的住房设计中.

The Colonization of Land

The Colonization of Land

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

What is Evolutionary History?

What is Evolutionary History?

Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.
