다국어 초록 (Multilingual Abstract)

This study was carried out in order to investigate the general performances of main characteristics at sexual maturity and the level of serum components according to growing stage from age at 70 days up to age at first egg in 16 layers.
The correlation coefficients among serum components were estimated for analysis of interaction on vitellogenesis at age of 70 days, 110 days, and sexual maturity, respectively.
The results obtained from this experiment were as follows;
1. Age at first egg, body weight, egg weight, shell weight, and shell thickness at first egg in Isabrown layers were 163.31±1.58days, 2,054.38±33.38g, 52.67±1.87g, 4.60±0.20g, and 0.34±0.01mm, respectively.
2. The contents of serum total protein, albumin, glucose, calcium, phosphorus, SGPT, and ALP increased highly significantly (P<0.01) according to increment of age.
Cholesterol and SGOT had tendency to decreased from age of 70 days to that of 110 days, but increased highly significantly (P<0.01) at age of first egg, sexual maturity. The content of globulin decreased gradually highly significantly (P<0.01) according to increment of age up to sexual maturity. The serum CPK and LDH enzymes decreased very highly significanty(P<0.01) according to increment of age.
3. On growing chickens at age of 70 days, the content of serum total protein was highly significantly correlated with g1obulin(r=0.912), glucose (r=0.533), respectively. The correlation between albumin and CPK was significantly negative with coefficient of -0.461.
The content of globulin was significantly positively correlated with glucose(r=0.629), and CPK(r=0.593), respectively.
The correlation between CPK and LDH was significantly negative with coefficient of -0.534.
4. On age at 110 days, the correlation between serum total protein and globulin was highly significantly positive coefficient with 0.826. The content of albumin was highly significantly correlated with globulin (r=-0.644), Phosphorus (r=0.602), and SGPT (r=0.456).
The content of glucose was significantly correlated with CPK(r=0.533), and LDH (r=0. 571).
The correlation coefficient between ALP and CPK was 0.508, significantly positive.
5. On age at first egg, the content of serum total protein was significantly correlated with globulin (r=0.887), and LDH(r=0.495), respectively.
The correlations between albumin and globulin, between calcium and CPK, between phosphorus and ALP, and between SGOT and ALP were significantly negative with coefficients of -0.589, -0.542, -0.512, and-0.497, respectively.
Otherwise, the content of CPK was significantly positively correlated with LDH (r=0.483).
