There is little information on maternal behaviour that deprives offspring of food, but some Japanese macaque, Macaca fuscata, mothers have been observed to snatch food from their offspring and eat it. This study investigated maternal food snatching behaviour (MFSB) and its impact on the growth of their offspring in provisioned, free-ranging Japanese macaques. The amount of food a mother snatched from her offspring was estimated to be 51.2% by dry weight compared to the amount of solid food an infant of the same age took in. Body mass growth of affected infants indicated a below-average mass gain. The study suggests that MFSB might be a pathological behaviour and provides the first detailed account of parental exploitation in animals.
关于剥夺幼崽食物的母性行为的信息很少，但有人观察到一些日本猕猴（Macaca fuscata）母亲会从幼崽手中抢夺食物并吃掉。本研究调查了圈养的、自由放养的日本猕猴的母性食物抢夺行为（MFSB）及其对幼崽生长的影响。据估计，母亲从幼崽那里抢夺的食物干重与同龄幼崽摄入的固体食物量相比为51.2%。受影响幼崽的体重增长表明其体重增加低于平均水平。该研究表明，母性食物抢夺行为可能是一种病态行为，并首次详细描述了动物中的亲代剥削现象。
