[Neophobia in rats during the transition from milk to definitive nutrition].
After isolation of rat puppies from mother at the age of 17, 21, 26, 31 or 36 days, studies have been made within 3 days on water consumption and utilization of a 0.2% solution of saccharin. The presence or absence of neophobia were indicated by relative consumption of saccharin solution in percentage to total volume of drinking. It was shown that at the age of 17-19 days neophobia is absent, at 21-23 days it becomes evident, at 26-28 days it is present only in females, at 31-33 days it is absent in animals of both sexes (saccharin consumption at this age is maximal), at 36-38 days significant neophobia was registered both in females and males. Fluctuations in neophobia are discussed in relation to weanling.
