测定了10头2周龄~ 2岁公猪血清雌酮（E1）、雌二醇（E2）、硫酸雌酮（E1 S）和睾酮（T）的含量。所有4种激素的浓度变化的特点是在新生儿发育期间（1至3周龄）升高，每种激素的浓度在1至3个月之间达到最低点。在青春期发育期间增加，在8个月时达到最大浓度。年龄，并没有进一步的变化，2岁。在所有年龄组中，E1 S在3种雌激素中占主导地位，平均浓度范围为2 - 33 ng/ml。在新生儿发育过程中，E1的浓度高于E2，而在4个月后观察到相反的情况。年龄。雄性猪的早期新生儿和青春期发育与血清雌激素浓度升高有关。
Serum concentrations of estrone (E1), estradiol (E2), estrone sulfate (E1S) and testosterone (T) were quantified in male pigs at 10 ages from 2 wk to 2 yr. Changes in the concentrations of all 4 of these hormones were characterized by elevated amounts during neonatal development (1 to 3 wk of age), a nadir for concentration of each hormone between 1 and 3 mo. of age, an increase during pubertal development with maximal concentrations at 8 mo. of age, and no further change by 2 yr of age. E1S was predominant of the 3 estrogens at all age groups with mean concentrations that ranged from 2 to 33 ng/ml. E1 was present in higher concentrations during neonatal development than E2, while the reverse situation was observed after 4 mo. of age. Early neonatal and pubertal development in male pigs is associated with elevated serum estrogen concentrations.
