AB [EN] - The objective of this study was to determine the impact of metabolicchanges occurring in induced subclinical gestation toxaemia in ewes on metabolicparameters and vigour in the first 72 h of their lambs’ life. Fifty-one adult Corriedaleewes of known gestation date and fed on a natural pasture were randomly dividedinto four groups at day 145 of gestation. Group A (ewes with single pregnancies) andgroup C (ewes with twin pregnancies) were fed on a natural pasture throughout thetrial; group B (ewes with single pregnancies) and group D (ewes with twin pregnancies)were subjected to 75% feed restriction for three days until they reached glycaemiaand β-hydroxybutyrate (BHB) values indicative of subclinical gestational toxaemia.The birth-to-first station and birth-to-first suckling times of the born lambs werestudied. Within the first hour after parturition and at 24, 48, and 72 h, glycaemia andBHB concentrations were determined in the blood of lambs, and body temperatureand body weight were assessed at the same time. Relative weight gain at 72 h of agewas calculated for all lambs. The BHB concentration determined at all times studiedshowed no difference among the groups. Subclinical gestation toxaemia induced inewes subjected to feed restriction causes a decrease in the glycaemia of their lambsin the first hour of life; however, it does not cause an increase in ketone bodies. Themetabolic changes induced in the mothers do not have negative effects on the vigour ofthe lambs at birth, as the weight, temperature, and the time it took for lambs to standand suckle are not affected. However, they have a negative effect on relative weight gainin the critical period of the first 72 h of life.
