This experiment was carried out to investigate the relationship of morphological characteristics between reticulum and abomasum of Korean native young goats age from 2 days to 150 days.Number of traits investigated in the reticulum in this experiment were 12[body weight, chest girth, body length, right and left reticulum length(R.L.), upper and lower reticulum length(U.L.), reticulum weight(R.W.), reticulum area(R.A.), upper and lower length of one polygon located at central part of reticulum(U.P.C.R.), right and left length of one polygon located at central part of reticulum(R.P.C.R.), thickness of polygon wall located at central part of reticulum(T.P.C.R.), thickness of polygon wall located at middle part of reticulum(T.P.M.R.), and thickness of polygon wall locared at edge part of reticulum(T.P.E.R.)] and items for abomasum were 12[length of between ostium omaso-abomasicum part and pylosica part in the abomasum(L. The results were summarized as follows: 1. Number of coefficient of correlation obtained among 12 traits of the abomasum and 12 of the reticulum were 144, and coefficient of correlation of 114 were significant(P 0.05).B2. Trait of abomasum weight have high correlation with 12 traits of reticulum. 3. Correlation coefficients and regression equation between body weight. VS. abomasum weight(r1), and upper and lower length of one polygon located at central part of reticulum(U.P.C.R.) VS. abomasum weight(r2) were r1 = 0.8954** and Y = 10.703 + 3.374X, r2 = 0.8430** and Y = 5.689 + 4.311X, respectively. 4. Correlation coefficients and regression equation between chest girth VS. abomasum weight(r1), and body weight VS. abomasum weight(r2) were r1 = 0.8708** and Y = 17.219 + 1.227X, r2 = 0.8589** and Y = 17.616 + 1.290X, respectively.
