Abstract/OtherAbstract:
Morphometric, metabolic and behavioral modifications were studied in goat kids after maternal feed restriction during the last third of pregnancy. At birth, only kids from twin and triplet litters were studied (n = 40 kids born to control dams (CONT) and n = 38 born to restricted dams (REST)) and only males thereafter (n = 13 CONT and 15 REST kids), until slaughter at 6 wk of age. Kids born to restricted goats had a smaller abdominal girth at birth (P < 0.01) and tended to have a lower BMI (P = 0.10) and a lower density index (P = 0.09) than kids born to control goats. Male REST kids had a lower birth weight (P = 0.03) than male CONT kids but no differences were found for weight and morphometric measurements thereafter. Nonesterified fatty acid concentrations suggested that male REST kids were mobilizing body reserves less at birth (P < 0.01). No modifications in drinking tests at 3 and 5 wk of age were observed, nor in feeding behavior and emotional reactivity at 5 wk of age. In conclusion, maternal feed restriction in the last third of pregnancy resulted in a decrease in birth size but male kids rapidly caught up and there were no changes in behavior, morphology or metabolism during rearing.
