Abstract
Data were collected from 1996 through 2000 on Korean Native Goats by the National Livestock Research Institute of Korea were used to estimate genetic parameters for birth, 3 month, and 6 month body weights. Estimates were obtained with MTDFREML. Model included animal and maternal genetic and residual effects. The model included sex, birth year-season, and feeding type as fixed factors. Average body weights and standard deviation were 1.78${\pm}$0.32 at birth of age, 7.99${\pm}$2.66 at 3 month of age, and 12.08${\pm}$3.20 kg at 6 month of age, respectively. Average body measurements were 36.46cm for withers height, 38.06cm for body length, and 45.56cm for heart girth at 3 month of age, and were 40.27cm for withers height, 42.01cm for body length, and 51.07cm for heart girth at 6 month of age, respectively. Estimates of heritability were 0.66 for birth weight, 0.34 for 3 month body weight, and 0.27 for 6 month body weight, respectively. Maternal effects would be important for birth and 3 month body weights and may not be needed in a model for 6 month body weight.
