The Maternal-Offspring Relationship in Tailed and Docked Ewes and Their Lambs

Applied Animal Behaviour Science

Maternal behavior in the hours after lambing is critical for establishing the lamb–dam bond. In rodents, early-life pain alters maternal behavior, but it is unclear whether routine painful procedures like tail docking have similar long-term effects in sheep. We tested whether neonatal tail docking in female lambs altered (1) their maternal behavior and their offspring’s behavior after lambing and (2) behavioral and physiological stress responses to separation.

Current Research Projects

  • My dissertation research investigates how tail docking female sheep impacts key social relationships from birth through their first pregnancy, specifically, her relationship with her:

    • Mother​

    • Peers and siblings

    • Sexual partner

    • Own lambs 

  • In addition to social implications, I am taking a holistic approach to evaluate the merits and pitfalls of tail docking by studying its influence on: 

    • Wound progression 

    • Suckling behavior

    • Disease risk 

    • Chronic pain 

    • Parturition pain

    • Pain sensitivity of offspring

  • Other projects:

    • ​Developed a methodology for estimating animal location from non-overhead video (see publications)

    • Validation of a novel real-time location system to track animal behavior

    • Classification of lying and standing behavior using accelerometer data & machine learning
