The trial was conducted to study the effects of different levels of vitamin A (VA) on blood indices of late gestating goats and on growth performance of the newborn lambs. Forty healthy Jining grey goats in late gestation (from 90 d of gestation to delivery) were allotted into 4 groups by a single-factor completely randomized block design, with ten heads in each group. The goats in control group were fed basal diet, while those in trial groups were fed basal diet supplemented with 1 100, 2 200 and 4 400 IU/kg VA, respectively. The results showed as follows: 1) for late gestating goats, supplementation of 1 100 IU/kg VA in diets increased the super oxide dismutase (T-SOD) activity in serum (P<0.05); supplementation of 2 200 IU/kg VA improved glutathione peroxidase (GSH-Px) activity in serum (P<0.05), but decreased malondialdehyde (MDA) content in serum (P<0.05); supplementation of 1 100 to 2 200 IU/kg VA improved total antioxidant capacity (T-AOC) in serum (P<0.05). 2) Supplementation of 1 100 IU/kg VA in diet increased the quantity of white blood cells (P<0.05); supplementation of 2 200 IU/kg VA improved the quantity of red blood cells (P<0.05) and the content of hemoglobin (P<0.05); supplementation of 2 200 to 4 400 IU/kg VA increased hematocrit (P<0.05). 3) Supplementation of 1 100 to 2 200 VA in diets increased the birth weight of lambs (P<0.05). In conclusion, the results indicate that supplementation of VA in diets can improve the immune function of late gestating goats and increase the birth weight of lambs. The proper adding levels are between 1 100 and 2 200 IU/kg.［Chinese Journal of Animal Nutrition，2011，23（1）：66-72］
