Summary
This summary is machine-generated.

Pair housing dairy calves, compared to individual housing, does not affect learning speed but improves their affective states. This suggests pair housing enhances calf welfare by promoting more positive emotional experiences.

Area of Science:

  • Animal Welfare Science
  • Comparative Psychology
  • Veterinary Ethology

Background:

  • Individual housing of dairy calves is a common practice with documented negative impacts on calf welfare.
  • Alternative housing strategies are needed to balance farming practices with animal well-being.

Purpose of the Study:

  • To compare the learning performance and affective states of individually housed versus pair-housed dairy calves.
  • To investigate if pair housing offers a welfare compromise over individual housing.

Main Methods:

  • Dairy calves were housed individually or in pairs and trained on a spatial Go/No-go operant task.
  • Learning speed for the operant task and discrimination task was assessed.
  • A judgment bias task using ambiguous cues was employed to evaluate affective states.

Main Results:

  • Housing treatment did not significantly affect the speed of learning the operant or discrimination tasks.
  • Pair-housed calves exhibited significantly more positive responses to ambiguous cues compared to individually housed calves.
  • This indicates a more positive affective state in pair-housed calves.

Conclusions:

  • Pair housing for dairy calves does not impair cognitive learning abilities compared to individual housing.
  • Pair housing demonstrably improves the affective state and overall welfare of dairy calves.
  • This study provides evidence supporting pair housing as a beneficial alternative to individual calf housing.
