Table 3 Correlations between different reproductive parameters in hens of different ages and reproductive states
From: Age-dependent role of steroids in the regulation of growth of the hen follicular wall
Reproductive parameters | r* | P |
|---|---|---|
Plasma concentration of estradiol-17β vs. Total volume of pre-ovulatory follicles (F1-F5) in the YLC hens | - 0.62 | < 0.05 |
Plasma concentration of estradiol-17β vs. Total volume of pre-ovulatory follicles (F1-F5) in the OLC hens | - 0.75 | < 0.01 |
Plasma concentration of estradiol-17β vs. Total volume of pre-ovulatory follicles (F1-F5) in the OSC hens | 0.60 | < 0.05 |
Plasma concentration of progesterone in the YLC and OLC hens vs. Time after ovulation | 0.53 | < 0.01 |
Plasma concentration of progesterone vs. Total volume of pre-ovulatory follicles (F1-F5) in the OLC hens | 0.78 | < 0.01 |
Plasma concentration of progesterone vs. Total volume of pre-ovulatory follicles (F1-F5) in the OSC hens | 0.62 | < 0.01 |
Plasma concentration of progesterone vs. Total volume of pre-ovulatory follicles (F1-F5) in the YLC, OLC, OSC, and OILC hens | 0.54 | < 0.001 |
