Low nutrient intake of piglets during the first few days after weaning is a serious problem which influences intestinal integrity and later performance (McCracken et al. 1999; Spreeuwenberg et al. 2001). Exposure to certain flavors during lactation could enhance diet acceptance in later life, stimulate ingestion, as well as improve adaptability to post-weaning conditions (Langendijk et al. 2007). Studies conducted in newborn animals and human infants suggested that maternal flavor intake transferred some chemosensory information to maternal milk and changes milk flavor, and eventually influencing post-weaning offspring diet acceptance (Mennella 2009). Furthermore, a study also found in pigs that flavor fed to lactating sows or weaning piglets could stimulate feed intake or improve the performance of piglets, especially at weaning or during the starter period (King 1979; McLaughlin et al. 1983; Torrallardona et al. 2000). In the present study, FMA flavor was well accepted by sows and piglets, which suggested a great consistency between maternal and filial flavor preference. Following this theory, supplementation with certain flavors to sows and their piglets during lactation could influence their later feeding behaviors, which provides a good way to improve feed intake and performance of sows and piglets.
