在一个月内，一头107厘米长的雌性儒艮幼仔于2004年2月3日和2004年3月2日两次搁浅在普吉省Paklok分区。首先，它被放回大海，然后被转移到普吉岛海洋生物中心饲养。小牛的口鼻处有一个很大的伤口，经过两个月的医疗护理，伤口完全愈合。牛奶浓度为15-30 g奶粉，体积为100 cc，每天给小牛4-5次，从100 cc开始，然后逐渐增加到500 cc。在2004年3月15日至30日期间，对它的行为进行了4次24小时的集中观察。结果发现，白天（06.00-17.59）24小时内的最小呼吸间隔时间为1秒，夜间（18.00-05.59）为2秒，而最大呼吸间隔时间为559秒（24小时和夜间）。每小时潜水次数的最小值：最大值分别为29：97（24小时和白天）和30：82（夜间）。似乎在虚弱的情况下，小腿经常浮出水面呼吸，不能像正常情况下那样长时间潜水。犊牛的胃肠道和肺部受到严重的细菌感染，在饲养期79天后死亡。
Within one month, a female dugong calf (Dugong dugon) of 107 cm long had twice been stranded at Paklok sub-district, Phuket province, on 3 February 2004 and 2 March 2004. Firstly, it was released back to the sea and secondly transferred to be reared at Phuket Marine Biological Center. The calf carried a large wound on its muzzle and the wound completely healed after medical care within 2 months. Milk, in a concentration of 15-30 g of powdered milk made up to 100 cc in volume, had been offered to the calf 4-5 times a day, starting from 100 cc and then gradually increasing to 500 cc. Its behaviors were intensively observed 24 hours, 4 times during 15-30 March 2004. It was found that the minimum breathing interval times were 1 second in 24 hours during daytime (06.00-17.59) and 2 seconds during nighttime (18.00-05.59) while the maximum was 559 seconds (24 hours and nighttime). The minimum: maximum numbers of diving time, per hour were 29:97 (24 hours and daytime) and 30:82 (nighttime). It seemed that in a weak condition, the calf frequently surfaced to breath and could not dive for long period as in a normal condition. The gastrointestinal tract and lungs of the calf were severly infected by bacteria and it died after 79 days of the keeping period.
