我们修改了一种能够量化行为的自动化方法，然后将其应用于与猪断奶后过渡相关的变化。该方法是数据驱动的，仅依赖于视频捕获的图像数据，而不依赖于传感器或额外的清管器标记。它被应用到视频图像产生的实验期间，断奶后的仔猪进行治疗，无论是含有或不含有饲料中的抗菌剂（氧化锌或抗生素）。预计这些处理通过最大限度地降低断奶后肠道疾病（如腹泻）的风险，在短期内影响仔猪的生产性能和健康。该方法量化了总的群体进食和饮水行为以及姿势（即，站立和非站立），此时断奶后腹泻的风险最高。行为的自动量化变化与不存在抗微生物剂对猪生产性能和健康的影响一致，表现为饲料效率降低和粪便松散。在这些仔猪饮水和站立的行为增加，在前6天断奶后。断奶后6天粪便硬度与饮水行为的相关性较高，提示饮水行为可能具有诊断价值。饲料中抗菌剂的存在或不存在对摄食行为没有影响，然而，随着时间的推移，这种影响会增加。这里开发的方法能够同时自动监测一组猪的几种不同行为，这可能是其作为诊断工具的价值所在。
We modified an automated method capable of quantifying behaviors which we then applied to the changes associated with the post-weaning transition in pigs. The method is data-driven and depends solely on video-captured image data without relying on sensors or additional pig markings. It was applied to video images generated from an experiment during which post-weaned piglets were subjected to treatments either containing or not containing in-feed antimicrobials (ZnO or antibiotics). These treatments were expected to affect piglet performance and health in the short-term by minimizing the risk from post-weaning enteric disorders, such as diarrhea. The method quantified total group feeding and drinking behaviors as well as posture (i.e., standing and non-standing) during the first week post-weaning, when the risk of post-weaning diarrhea is at its highest, by learning from the variations within each behavior using data manually annotated by a behavioral scientist. Automatically quantified changes in behavior were consistent with the effects of the absence of antimicrobials on pig performance and health, and manifested as reduced feed efficiency and looser feces. In these piglets both drinking and standing behaviors were increased during the first 6 days post-weaning. The correlation between fecal consistency and drinking behavior 6 days post weaning was relatively high, suggesting that these behaviors may have a diagnostic value. The presence or absence of in-feed antimicrobials had no effect on feeding behavior, which, however, increased over time. The approach developed here is capable of automatically monitoring several different behaviors of a group of pigs at the same time, and potentially this may be where its value as a diagnostic tool may lie.
