Abstract/OtherAbstract:
Feed restriction during pregnancy can have detrimental effects on offspring development both during the juvenile period and during adult life. Long-term effects of maternal feed restriction during the last third of pregnancy on growth, metabolism and behavior of female kids, with a focus on feeding behavior and emotional reactivity, were studied in goats. Female kids born to control (CONT, n=17) or born to feed restricted goats (REST, n=15) were artificially reared and monitored from birth to 24months of age. Maternal feeding restriction globally reduced live weight (P<0.001) and body condition score (P=0.02) of REST compared to CONT offspring. Females from the REST group had a higher daily feed intake (P=0.05) and tended to eat more rapidly (P=0.09) than females from the CONT group at 12months of age. One year later, REST goats still ate more than CONT goats (P=0.05). Glucose metabolism did not appear to be modified as no differences were observed in glucose or insulin responses to an intravenous glucose tolerance test. No differences in time budget were found at 12months of age. However, the HPA axis response to an ACTH injection was greater in REST than in CONT goats: higher peak cortisol concentration (P=0.02) and a greater area under the curve were found (P=0.01) at 14months of age. In conclusion, maternal feed restriction during late pregnancy modified both feeding behavior and the stress physiology of female offspring for up to 2years of age. However, the changes observed were small.
