The global population is expected to increase from 7.6 to 9.6 billion people from 2017 to 2050. Increased demand for livestock production and rising global temperatures have made heat stress (HS) a major challenge for the dairy industry. HS been shown to have negative effects on production parameters such as dry matter intake, milk yield, and feed efficiency. In addition to affecting production parameters, HS has also been shown to have negative effects on the reproductive functions of dairy cows. Mitigation of HS effects on dairy cow productivity and fertility necessitate the strategic planning of nutrition, and environmental conditions. The current review will discuss the potential nutriepigenomic strategies to mitigate the effect of HS on bovine embryo.
预计全球人口将从2017年的76亿增加到2050年的96亿。对畜牧生产需求的增加和全球气温的上升使热应激(HS)成为乳制品行业面临的一项重大挑战。热应激已被证明会对干物质摄入量、产奶量和饲料效率等生产参数产生负面影响。除了影响生产参数外,热应激还被证明会对奶牛的繁殖功能产生负面影响。减轻热应激对奶牛生产力和繁殖力的影响需要对营养和环境条件进行战略规划。本综述将讨论减轻热应激对牛胚胎影响的潜在营养表观基因组学策略。
