Abstract
Effects of Providing a Liquid Sensory Attractant to Suckling Pigs in Lactation and After Weaning on Post-Weaning Pig Performance
Highlights
Sensory learning encourages pigs to use their senses to explore their environment
A total of 28 litters (241 × 600, DNA) corresponding with 355 nursery pigs (241 × 600, DNA; initially 13.0 lb) were used in 42-d trial (17-d pre-weaning and 24-d post-weaning). This trial was conducted to determine the effect of providing a sensory attractant liquid (BlueLite Pro2Lyte; TechMix Global; Stewart, MN) to suckling pigs on the underline of sows after farrowing and in late lactation, and after weaning on post-weaning feed intake and growth
Pre-weaning liquid sensory attractant did not have a significant effect on piglet weaning weight or post-weaning growth performance
Summary
Using sensory learning in combination with feeding could ease the weaning transition by training pigs to respond to familiar taste, odor, or texture stimuli. It has been suggested that providing the same stimuli both before and after weaning may further increase feed acceptance after weaning as a result of association.[5] We hypothesized that applying a liquid sensory attractant at various stages of early life including on the underline of sows after farrowing and prior to weaning, and on the feed post-weaning would condition pigs to the taste and smell of the attractant. Applying liquid sensory attractant pre- and post-weaning was postulated to evoke the greatest response as it would provide pigs familiar olfactory stimuli, reducing feed neophobia post-weaning. The objective of this study was to determine the effects of a liquid sensory attractant preand post-weaning on the feed intake and growth of pigs after weaning
