摘　　要：仔猪在断奶时面临一个挑战,即它们的饮食结构不得不从吮吸母乳过渡到独立采食健康及营养的固体饲料。此时会导致仔猪对新饲料产生新奇恐惧症,它们通常会出现一段时间的厌食、体质下降和应激行为。一些风味已经被证明,可以从母体采食的饲料中少量转移到羊水和乳汁中,使胎儿或幼龄动物从母体采食的饲料中获得气味,减少在断奶时对同样口味类型饲料的新奇恐惧症。文章旨在通过论述母猪围产期风味剂印迹训练提高断奶仔猪的采食偏好,增加断奶仔猪初期的采食量,为现代养猪业改善仔猪健康和福利,提高其经济效益寻找一种可行的方法。Piglets are faced with a challenge at weaning that they have to make the transition from suckling mother＇s milk to the independent selection and ingestion of healthy and nutritional solid feeds. This leads to the piglets to produce a neophobia for the new feeds,showing a period of anorexia,reduced health,and stress- induced behaviors. Some flavors have been demonstrated to be transferred in small amounts from the maternal diet to the amniotic fluid and milk. The fetuses of young animals can get the flavors from the maternal diet,which can reduce the neophobia for same type and flavor of feeds at weaning. This paper aims to increase the intake of early weaned piglets through discussing the imprint training with flavors to improve the feeding preferences of weaned piglets during the perinatal period in the sows,and seeks a feasible method to improve the health and welfare of piglets in modern pig industry and increase the economic benefit.
