Overnutrition or undernutrition during all or part of the reproductive cycle predisposes sows to metabolic consequences and poor reproductive health which contributes to a decrease in sow longevity and an increase in perinatal mortality. This represents not only an economic problem for the pig industry but also results in poor animal welfare. To maximise profitability and increase sustainability in pig production, it is pivotal to provide researchers and practitioners with synthesised information about the repercussions of maternal obesity or malnutrition on reproductive health and perinatal outcomes, and to pinpoint currently available nutritional managements to keep sows' body condition in an optimal range. Thus, the present review summarises recent work on the consequences of maternal malnutrition and highlights new findings.
在繁殖周期的全部或部分阶段,营养过剩或不足会使母猪易发生代谢后果和生殖健康不良,这导致母猪寿命缩短和围产期死亡率增加。这不仅是养猪业的一个经济问题,还导致动物福利不佳。为了使养猪生产的利润最大化并提高可持续性,为研究人员和从业者提供关于母体肥胖或营养不良对生殖健康和围产儿结局的影响的综合信息,并确定目前可用的营养管理措施,以保持母猪的身体状况处于最佳状态至关重要。因此,本综述总结了母体营养不良的后果的最新研究,并强调了新的发现。
