TI  - Sensory systems and nipple attachment behavior in neonatal pigs.
PG  - 1-4
AB  - The influence of piglet sensory systems and the role of odors from the sow's 
      ventrum on piglet nipple attachment were investigated. In Experiment 1, four sows 
      had their ventrum washed with organic solvents and four were unwashed control 
      sows. Piglets were given one of four treatments shortly after birth: nares that 
      were mechanically blocked (B), a lidocaine flush of the olfactory system (LFO), a 
      saline flush of the olfactory system (SFO) or nontreated controls (C). Time to 
      attach to a nipple, up to a maximum of 600 sec, was recorded. On unwashed sows, 
      nipple attachment was affected (p less than 0.01) by piglet treatment. Piglets 
      have B or LFO treatments took longer to attach to a nipple than SFO or C piglets. 
      Piglets of all treatments took longer to attach to washed sows than to unwashed 
      controls. Seven unwashed sows and their litters were used in Experiment 2. 
      Piglets were tested after birth with one of the following treatments: an 
      olfactory system flushed with lidocaine, lidocaine on nose (LN), lidocaine 
      applied to the tongue (LT) or nontreated controls. All lidocaine-treated piglets 
      took more time to attach than C piglets. Nipple attachment latencies were 
      intermediate for LN or LT piglets. In Experiment 3, three unwashed sows and their 
      litters were used. Treatments were: lidocaine applied to both the nose and the 
      tongue (LNT), an olfactory system flushed with lidocaine or nontreated controls. 
      LFO piglets had an increased latency to attachment compared to controls while LNT 
      piglets were intermediate in latency to attach. Piglet olfaction, gustation and 
      tactile sensory modalities as well as odors on the sow's ventrum influenced 
      nipple attachment.(ABSTRACT TRUNCATED AT 250 WORDS)
