This experiment was conducted in order to investigate the morphological form of rumen of Korean native goats, which were purchased at Jinju animal market from February, 1979 to December, 1979. The numbers of experimental animal were 23 heads. Rumen investigated way, divided into 3 parts which represent part of dorsal sac, caudal dorsal blind sac, cranial dorsal blind sac (ABC), caudal ventral blind sac (D), and ventral sac (E), as shown in Fig 1. The items investigated in this experiment were 27 such as age, body weight, chest girth, body length, right and left rumen length, upper and lower rumen length, ingests and stomach weight, stomach weight, rumen weight, and area, thickness (Max.), weight, papillae width, papillae length of ABC parts, D part, E part, and minimum thickness of ABC parts, D part, E part. The results were summarized as follows: 1) In the results of judging, age of Korean native goats used in this experiment was from 1 to 2 years, average body weight was 19.270 ㎏, average chest girth was 60.426 ㎝, and average body length was 53.965㎝. 2) Right and left length of rumen was 32.162 ㎝, upper and lower length of rumen was 28.735 ㎝, average stomach weight was 571.609 g, weight of ingests and stomach was 3.955 ㎏ and rumen weight was 380.261 g. 3) In the results of total ABC parts of rumen, area, meximum thickness of rumen wall, minimum thickness of rumen wall, weight, papillae width, and paillae length were 726.146 ㎠, 1.987 ㎜, 1.244 ㎜, 207.391 g, 2.322 ㎜, and 6.268 ㎜, respectively. 4) In the results of D part of rumen, area, maximum thickness, minimum thickness, weight, papillae width, and papillae length were 269.444 ㎠, 1.390 ㎜, 1.063 ㎜, 56.522 g, 1.975 mm and 5.087 mm, respectively. 5) In the results of E part of rumen, area, maximum thickness, minimum thickness, weight, papilla width, and papillae length were 436.250 ㎠, 1.664 ㎜, 1.063 ㎜, 112.939 g, 2.234 ㎜ and 5.309 ㎜, respectively. 6) In the total of 351 items investigated, 187 items have a significant differences (P$lt;0.01 - P$lt;0.05). Regression equation of 187 items were shown in table 3. 7) Significant (p $lt; 0.01) correlation coefficients between body weight and rumen area (r₁), and body weight and ingesta stomach (r₂) was 0.8269 for r₁(Y = 54.4011X + 383.583) and 0.6884 for r₂ (Y = 0.175X + 0.032).
