金定鸭睾丸生长发育规律的初步研究
Preliminary study on the growth and development of Jinding duck testes
摘要
Abstract
This study aimed to explore the growth and development patterns and sexual maturity characteristics of Jinding duck testes.The testicular weight,testicular volume,number of interstitial cells per unit area,and area of seminiferous tubules of Jinding ducks aged 2 to 58 weeks were measured using morphological and histological methods.At the same time,ELISA was used to detect the serum testosterone levels of the ducks at 2,6,10,16,24,43 and 58 weeks of age,and the correlation analysis was conducted with indicators related to testicular de-velopment in the ducks.The results showed that the testicular development of the Jinding ducks exhibited significant age-related changes,manifested as an increasing trend in testicular weight,volume,index,and testosterone content from 2 to 43 weeks of age,while their testos-terone content decreased at 58 weeks of age(P＜0.05).The area of seminiferous tubules increased continuously from 2 to 26 weeks of age,and gradually decreased from 26 to 58 weeks of age.The change trend of the number of interstitial cells per unit area was opposite to that of seminiferous tubule area.The correlation analysis showed that the body weight,testicular weight,testicular volume,testosterone content,and seminiferous tubule area of the Jinding ducks were significantly(P＜0.05)or extremely significantly(P＜0.01)positively correlated with each other.The number of interstitial cells per unit area was significantly(P＜0.01)negatively correlated with body weight,testicular weight,testosterone content,seminiferous tubule area,and testicular volume.This was a preliminary study on the developmental patterns of Jinding duck testes at different years of age,which laid a theoretical foundation for research on the mechanisms and functions of testicular development in ducks.关键词
