Abstract

Electrocoagulation of 50% of the parafornical area was found to cause a considerable disturbance of maternal behaviour and foetal vitality. Food and water uptake of the damaged animals reached the initial level at the time of parturition. The decrease in body weight was not compensated due to foetal development. Body temperature was essentially normal. Maternal behaviour during delivery was normal, retrieving and nest building activities appeared only in one third of the animals and nursing was also of a reduced degree. Adenohypophyseal prolactin content was significantly higher than in the control group, but in somatotropin content there was no difference between the two groups. The lower birth weights and live birth ratio pointed to intra uterine foetal lesions. (11 references)
