Pups born to dams receiving a low protein diet (7% casein by weight) were fostered at birth to well\u2010nourished dams and behavioral observations were made at 4\u2010day intervals. Dams nursing gestationally malnourished pups were observed to spend more time in the nesting area with their pups towards the end of lactation. Moreover, the behavioral development (locomotion, feeding, and rearing and climbing activity) of gestationally malnourished offspring was depressed when compared to their controls. The results indicate that prenatal undernutrition alters the behavioral development of the offspring and maternal behavior of the dam in a manner which reduces the exposure of the pup to the immediate environment.<\/jats:p>","DOI":"10.1002\/dev.420100408","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T22:39:31Z","timestamp":1104619171000},"page":"339-345","source":"Crossref","is-referenced-by-count":22,"title":["Protein malnutrition induced during gestation: Its effect on pup development and maternal behavior"],"prefix":"10.1002","volume":"10","author":[{"given":"Thomas F.","family":"Massaro","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David A.","family":"Levitsky","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard H.","family":"Barnes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,10,13]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"crossref","first-page":"273","DOI":"10.1093\/jn\/103.2.273","article-title":"Maternal protein deprivation during pregnancy or lactation in rats and the efficiency of food and nitrogen utilization of the progency","volume":"103","author":"Barnes R.
