Multiple biopsies of guinea pig mammary glands during pregnancy and lactation.
Mammary gland biopsies were obtained from 39 guinea pigs during late pregnancy, lactation and weaning. Up to eight samples, each weighing 60--200 mg, were taken from each animal in two independent studies. No mortalities resulted, and no interference with lactation or suckling was observed.
