概括

道路运输会导致孕的氧化应激,但补充维生素E和 (ESe) 可以减轻这些影响. ESe管理提供了一个潜在的策略,以改善动物在运输过程中的福利.

科学领域:

动物科学动物科学
兽医医学兽医医学兽医医学
动物福利动物福利

背景情况:

道路运输是牲畜常见的压力因素,可能会影响生理和行为参数.
氧化压力和炎症是动物对运输压力的关键反应.
维生素E和 (ESe) 是重要的抗氧化剂,有可能调节应激反应.

研究的目的:

调查公路运输和维生素E/ (ESe) 补充剂对孕乳牛生理标志物和行为的影响.
为了确定ESe的管理是否可以缓解运输引起的压力诱导的变化.

主要方法:

40只怀孕的荷尔斯坦公牛被分为四组:运输/没有ESe,没有运输/ESe,运输/ESe和没有运输/没有ESe.
从运输前7天到运输后3天,每天口服ESe.
在多个时间点收集血液样本,并在运输后进行行为观察.

主要成果:

没有ESe的运输公牛表现出皮质醇,平分球蛋白,氧化应激标志物,非化脂肪酸的增加,以及白细胞形状的改变.
没有ESe的运输公牛也表现出较短的躺时间.
服用ESe部分减轻了运输的负面影响,降低了皮质醇,氧化应激和平分球蛋白水平,同时改善了抗氧化状态.

结论:

道路运输会在孕乳母牛中引发暂时的氧化应激和生理障碍.
维生素E和 (ESe) 补充剂可以部分缓解运输引起的压力反应.
通过ESe的管理,可以有效地提高运输中的孕母牛的动物福利.

关键词:

氧化应激是一种氧化应激.怀孕的奶牛母牛是一个孕妇.是一种.运输运输运输运输运输运输运输运输维生素E 维生素E 是一种维生素.

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
