As young pigs grow, their daily feed intake significantly increases, while the frequency of eating bouts decreases. This leads to larger, longer eating sessions and more water consumption associated with meals.

Area of Science:

  • Animal Science
  • Behavioral Science
  • Physiology

Background:

  • Understanding feeding and drinking patterns is crucial for animal husbandry and welfare.
  • Growth significantly impacts an animal's physiological needs and behaviors.

Purpose of the Study:

  • To investigate how feeding and drinking behaviors change in immature female pigs as they grow.
  • To determine the relationship between feed and water intake patterns and body weight.

Main Methods:

  • Operant conditioning was used to allow pigs to obtain feed and water.
  • Log survivorship analysis identified eating bout intervals.
  • Data collected on feeding and drinking patterns across a weight range of 10 to 130 kg.

Main Results:

Related Experiment Videos

  • Daily feed intake increased threefold as pigs grew from 10 to 130 kg.
  • Eating bout frequency decreased, while bout size and inter-bout intervals increased.
  • Water intake was strongly linked to eating bouts, with a significant portion occurring preprandially.
  • Most feeding and drinking occurred during the light period, with larger, less frequent nocturnal bouts.

Conclusions:

  • Growth is a primary driver of changes in feeding and drinking patterns in young pigs.
  • Pigs adapt their feeding strategies, increasing intake rate rather than duration, as they grow.
  • Water consumption is highly integrated with feeding behavior, suggesting a coordinated physiological response.
