妊娠后期母兔血浆激素水平对仔兔的影响
Influence of Postpregnant Maternal Serum E2、TH on Rabbit Neonate
摘要
Abstract
To investigate the effect of endocrine of female rabbits during late pregnancy on the development of fetal and weaning rabbits, 13 Wan strain Angora rabbits were divided into three groups. On day 16,17 and 18 of gestation, 5 rabbits of experimental group 1 were intramuscularly injected with 0. 1 mg thyroxine (T4), 4 rabbits of experimental group 2 with 0. 1 mg oestradiol benzoate(E2),4 rabbits of the control with 0. 9% saline. After treatment with OB, lower birth weight, 4-week weight and 6-week weight were observed, and neonate serum T3、T4 and insulin levels were significantly decreased(P<0.05or P<0.01). Treatment with T4 increased newborn rabbits serum insulin level(P<0.05), not T3、T4 levels, and increased 7~14 day, 21~28 day and 35~42 day weaning rabbits growth speed significantly(P<0.05). Although treatment with T4 had no effect on birth weight, 4-week weight and 6-week weight significantly(P>0.05). Plasma E2 levels of female rabbits pregnancy on 20d and birth weight, 4-week and 6-week weight of weaning rabbits were strongly negatively correlated, correlation coefficients were -0. 927(P<0.01), -0. 866 (P<0.01) and -0. 810 (P<0.05), respectively. Plasma insulin levels of newborn rabbits and body weight.of 4-week, 6-week of weaning rabbits were strongly positive, correlation coefficients were 0. 887 (P<0.01) and 0. 932 (P<0.01), respectively.关键词
