Primates: Change the number of feeds per day
A before-and-after study in 2012 in the USA (Nevill & Lutz 2015) found that increasing feeds from one to two per day increased hair-eating in baboons Papio hamadryas sp. When one feed was provided, hair eating was seen during 1% of the observations, increasing to 3% with two feeds. Eleven baboons, housed as a social group, were offered their standard feed of 5 kg of monkey diet in the afternoon, which was then split into two, 2 kg feeds, given morning and afternoon. Each monkey was observed over six months and two hours of data were collected on each animal. (CJ)
