  1. 1. THE INFLUENCE OF FEEDERS TYPE AND THE METHOD OF GROUP ALLOCATION IN PIGLETS GROWTH Valencia Urdín, Joseba Pascual Guzmán, Antón Archanco Urroz, Xabier Armendáriz López, Luismiguel
  2. 2. INDEX <ul><li>INTRODUCTION </li></ul><ul><li>OBJETIVES </li></ul><ul><li>MATERIAL AND METHODS </li></ul><ul><li>RESULTS </li></ul><ul><li>DISCUSSION </li></ul>
  3. 3. INTRODUCTION <ul><li>After weaning piglets growth is stopped </li></ul><ul><li>1- Change: suckled ate fodder </li></ul><ul><li>2- T he aggressiveness between the piglets </li></ul><ul><li>Reduced spaces and mixed piglets from different litters, higher aggressiveness </li></ul><ul><li>The voluntary food intake is stimulated when piglets eat with water. </li></ul>
  4. 4. Littermate Non-littermate
  5. 5. “ Wet and dry” single-space feeders Multi-space feeders “Dry” single-space feeders
  6. 6. <ul><li>In single-space feeders decrease the fightings </li></ul><ul><li>Most secure and less fights, we think that more food are intake </li></ul><ul><li>Disadvantages of the single-space feeders is that more food is wasted. </li></ul><ul><li>Piglets are weighted and the food intake is measured weekly. </li></ul>
  7. 7. OBJETIVES <ul><li>Observing the differences in piglets growth among: </li></ul><ul><ul><li>The differents types of feedders </li></ul></ul><ul><ul><li>The differents types of group allocation </li></ul></ul>
  8. 8. MATERIAL AND METHODS <ul><li>Piglets with 30 days and 9 kg were housed in groups of nine. </li></ul><ul><li>Six kinds of groups were studied:  </li></ul><ul><ul><li>“ Wet and dry” single-space feeders with littermate piglets. </li></ul></ul><ul><ul><li>“ Wet and dry” single-space feeders with mixed litter piglets. </li></ul></ul><ul><ul><li>“ Dry” single-space feeders with littermate piglets. </li></ul></ul><ul><ul><li>“ Dry” single-space feeders with mixed litter piglets. </li></ul></ul><ul><ul><li>Multi-space feeders with littermate piglets. </li></ul></ul><ul><ul><li>Multi-space feeders with mixed litter piglets. </li></ul></ul>
  9. 9. <ul><li>Four weeks: </li></ul><ul><ul><li>The two first weeks different diet for the two following weeks </li></ul></ul>
  10. 10. RESULTS <ul><li>I n the first week “Wet and dry” single-space feeders less growth than “dry” single-space feeders and multi-space feeders. </li></ul><ul><li>Multi-space feeders more food intake than a single-space feeder. </li></ul><ul><li>But the differences in intakes between pens were high too because of other causes. </li></ul>
  11. 11. DISCUSSION <ul><li>“ wet and dry” single-space feeders eat more </li></ul><ul><li>doesn’t increase piglets growth </li></ul><ul><li>Single-space feeders and multi-space feeders have similar growth. </li></ul><ul><li>There are two possibilities that explain: </li></ul><ul><li>1- Complicated interaction between piglets and feeders. </li></ul><ul><li>2- Older pigs are more receptive to different forms of feeding than piglets. </li></ul>
  12. 12. <ul><li> Few hours, vigorous fights </li></ul><ul><li>Non-littermate piglets </li></ul><ul><li> After 48 h., occasional fights. </li></ul><ul><li>Piglets than littermates haven’t fights </li></ul><ul><li>Non-littermate piglets, growth faster in the first 14 days than littermate piglets </li></ul>
  13. 13. <ul><li>No differences between “wet and dry” and “dry” single spaces feeders. </li></ul><ul><li>Non-littermate piglets fight more and intake more food than littermate piglets. </li></ul>
