摘要

家畜可以通过神经和激素反应机制来适应现代生产实践的影响。这种机制可能有生物成本,表现为生长或生产力下降以及抗体活性下降。然而,在大多数家养物种中存在适应性的遗传变异,因此对身体和行为应激源的反应性降低的选择是可能的。

Effects of intensive production methods on livestock health

Domesticated animals can adjust to the effects of modern production practices by employing neural and hormonal response mechanisms. Such mechanisms may have biological costs that appear as reduced growth or productivity and a decline in antibody activity. However, there exists within most domestic species genetic variation for adaptivity so that selection for reduced responsiveness to physical and behavioral stressors is possible.
