Replication Data for: Rearing Laying Hens: environmental complexity and genetic strain affect pullet but not chick performance in a T-maze learning task
Borealis
Rentsch, K., Ana; Harlander, Alexandra; Niel, Lee; Siegford, Janice; Widowski, M. Tina — 2023-04-06 We used two learning tests to test three hypotheses using chicks and pullets of brown and white layer strains reared in cages and aviaries of varying complexity. 1) Does increased spatial complexity during early life improve the performance of laying hen chicks/pullets in a T-maze? 2) Does chick/pullet performance in a two-dimensional learning task differ between genetic strains? 3) Is there an interactive effect of genetic strain and rearing environment on performance in the tasks?

Effect of a standardized 4-week desensitization and counter-conditioning training program on pre-existing veterinary fear in companion dogs
Borealis
Stellato, Anastasia C.; Jajou, Sarah; Dewey, Cate E.; Widowski, Tina M.; Niel, Lee — 2019-10-04 Dogs were recruited with pre-existing veterinary fear to assess the efficacy of a 4-week counter-conditioning and desensitization training program on behavioural and physiological indicators of fear. For dogs that were randomized to receive training (n=15), their owners were instructed to perform exam-style handling on their dog and visit the veterinary clinic on a weekly basis for 4-weeks. For control dogs (n=22), owners were not given any instructions between testing. Dogs were assessed during arrival at the clinic entrance (entering clinic and weigh-in) and during a routine standardized examination before and training.

Replication Data for: Raising Laying Hens: housing complexity and genetic strain affect startle and behavioural response to fear stimuli
Borealis
Rentsch, K., Ana; Harlander, Alexandra; Niel, Lee; Siegford, Janice; Widowski, M. Tina — 2023-04-05 In this paper, we asked whether the degree of early complexity (minimal, low, moderate, or high), genetic strain (brown vs white feathered), or their interaction affects fear behaviour (type and intensity) in laying hen pullets in different fear-inducing situations: 1) a startle response test, 2) a novel arena, and 3) a novel object test.
