缩短母猪分娩时间的靶向营养措施OA

The farrowing process in sows consists of three distinct stages:the prepartum preparation stage,the fetal expulsion stage,and the placental expulsion stage.Prolonged duration of farrowing directly reduces fetal oxygenation status,thereby compromising neonatal piglet survival rates and impairing colostrum yield,ultimately compromising farm profitability.Traditional sow feed formulas primarily address the basic energy,amino acid,vitamin,and mineral requirements for maternal maintenance and fetal growth,which may inadequately meet the specific reproductive demands of modern hyper-prolific sows.Consequently,attention must be given to incorporating specific nutrients that enhance placental angiogenesis,improve embryonic development,and support uterine contractions.Implementing these targeted nutritional strategies can effectively shorten farrowing duration and enhance piglet vitality.
