The effect of bromocriptine treatment on total duration of pup retrieval (A), latency to nurse (B), duration of nursing (C), and time on nest (D). Values shown are means + SEM. (A) Combined groups of dams treated with bromocriptine (10 rats at a dose of .05 mg/kg, 8 rats at a dose of .2 mg/kg) took significantly longer to retrieve all eight of their pups in a novel cage compared to a home cage (t = 3.56, *p = .002). Rats treated with the vehicle did not differ in home and novel cage pup retrieval latencies. (B) Dams treated with bromocriptine took significantly longer to initiate nursing in a novel cage compared to a home cage (t = 2.11, *p < .001). Rats treated with the vehicle did not differ in latency of nursing between the home and novel cages. (C) Dams treated with bromocriptine spent a significantly shorter amount of time nursing their pups in a novel cage compared to a home cage (t = 2.86, *p = .01). Rats treated with the vehicle and tested in the home and novel cages did not differ in nursing duration. (D) Dams treated with bromocriptine spent a significantly shorter time on the nest in a novel cage compared to a home cage (t = 2.07, *p = .027). Rats treated with the vehicle did not differ in time spent on the nest in the home and novel cages.
