Supplemental data: Play behaviour positively relates to weight gain, feeding behaviour and drinking behaviour in weaner pigs (Sus scrofa)

We explored the relationship between two types of play behavior and measures of nutritional status (i.e., weight gain, feeding behavior, and drinking behavior) in weaner pigs. Our study demonstrated that motivation to play is higher when animals are in more stable conditions, e.g., well-nourished, and healthier than under suboptimal conditions. The present study titled "Play behaviour positively relates to weight gain, feeding behaviour and drinking behaviour in weaner pigs (Sus scrofa)" and submitted to Applied Animal Behaviour Science on October 25, 2022 was conducted from February to November 2020 at the experimental facilities at the Department of Animal and Veterinary Sciences, Aarhus University, Viborg, Denmark. The experimental procedures were carried out in accordance with the Ministry of Food, Agriculture and Fisheries, The Danish Veterinary and Food Administration under act 474 of 15. May 2014 and executive order 2028 of 14. December 2020, and under consideration of the ARRIVE Guidelines (Du Sert et al., 2020). The present study is part of a large study examining the clinical, physiological, and behavioural effects of weaning intact litters in farrowing pens for loose-housed sows and alternative sow hybrid described in detail by Franchi et al. (2022) and Winters et al. (2022). Herein, the supplemental data is made available.

本研究探究了断奶仔猪（weaner pigs）的两类玩耍行为与营养状况指标（即增重、采食行为及饮水行为）之间的关联。研究结果表明，相较于次优环境，当动物处于更稳定的环境（如营养良好、健康状态更佳）时，其玩耍动机更强。本研究题为《断奶仔猪（Sus scrofa）玩耍行为与增重、采食行为及饮水行为呈正相关》，于2022年10月25日提交至《应用动物行为科学（Applied Animal Behaviour Science）》，实验于2020年2月至11月在丹麦奥胡斯大学（Aarhus University）动物与兽医科学系位于维堡（Viborg）的实验设施中开展。实验操作严格遵循丹麦食品、农业与渔业部及丹麦兽医与食品管理局发布的2014年5月15日第474号法案与2020年12月14日第2028号行政命令，并符合ARRIVE指南（ARRIVE Guidelines）的相关要求。本研究是一项大型研究的子课题，该大型研究旨在探究散养母猪分娩栏中完整窝仔猪断奶，以及新型母猪杂交品系相关的临床、生理及行为效应，相关细节已由Franchi等（2022）与Winters等（2022）详细阐述。本文同步提供补充数据集。
