As the demand for food increases with exponential growth in the world population, it is imperative that we understand how to make livestock production as efficient as possible in the face of decreasing available natural resources. Moreover, it is important that livestock are able to meet their metabolic demands and supply adequate nutrition to developing offspring both during pregnancy and lactation. Specific nutrient supplementation programs that are designed to offset deficiencies, enhance efficiency, and improve nutrient supply during pregnancy can alter tissue vascular responses, fetal growth, and postnatal offspring outcomes. This review outlines how vascularity in nutrient transferring tissues, namely the maternal gastrointestinal tract, the utero-placental tissue, and the mammary gland, respond to differing nutritional planes and other specific nutrient supplementation regimes.
随着全球人口呈指数增长,对食物的需求也不断增加,因此我们必须明白,在自然资源日益减少的情况下,如何尽可能提高畜牧生产效率。此外,重要的是,家畜要能够满足自身的代谢需求,并在怀孕和哺乳期间为发育中的后代提供充足的营养。旨在弥补营养不足、提高效率并改善孕期营养供应的特定营养补充方案,能够改变组织血管反应、胎儿生长以及产后子代结局。本综述概述了营养转运组织,即母体胃肠道、子宫 - 胎盘组织和乳腺中的血管如何对不同的营养水平和其他特定营养补充方案做出反应。
