초록


The objective of this study was to estimate the growth curve parameters of body weight for female Elk. Weight and age data from 115 does raised at the Animal Genetic Resources Research Center in Korea were used in this study. The growth curve parameters were estimated from a nonlinear regression using Gompertz and Logistic models. Mature weight (A), growth ratio (b) and maturing rate (k) of female Elk were 214.1±2.17 kg, 2.12±0.0045 and 0.0043±0.00011, respectively, according to the Gompertz model. They were 208.3±2.17 kg, 5.56±0.234 and 0.0065±0.00017, respectively, according to the Logistic model. The goodness of fit determined by R2 was higher in the Gompertz model than that in the Logistic model. The growth curve functions obtained from the Gompertz and Logistic models in female Elk were f(t)=214.1×e-2.124×e-0.00484×t and f(t)=208.3×(1+5.561×e-0.00651×t)-1,  respectively. The absolute growth rate functions from the Gompertz and Logistic models in female Elk were f'(t)=0.0043×f(t)×1n(214.1/f(t)) and f'(t)=0.0065×f(t)×[1-f(t)/208.3]respectively. The growth pattern of female Elk generated from this study can be useful in determining the most appropriate feeding plans and the best breeding strategies for deer.
