This experiment was conducted at theForage Research Farm of the Beef and Dairy Cattle Division, National Livestock Research Institute, Songhwan in 1992 and 1995 to investigate the effects of planting time (April 15, May 11, June 5) on the growth and yield of silage com(Zea mat`s L.). In the plant height, P3144W and DK729 were taller than the others, as 301.6, and 296.3cm, respectively, and P3282 was the shortest as 247.7㎝ at the first planting time. P3144W and DK729 were taller than the others, as 303.6㎝, 281.7㎝, respectively, and P3282 was the shortest as 249.6㎝ at the second planting time. P3144W was the tallest as 276.9㎝. DK689 was the shortest as 246.1㎝ at the third planting time. The ear heights of P3144W and P3282 were 137.3 and 132.7㎝, respectively, and Suweon 19 was the shortest as 116.4㎝ at the first planting time. Those of P3144W and P3282 were as 135.9, 134.4㎝, respectively, and Suwoen 19 was the shortest as 112.1㎝ at the second planting time. P3144W was the tallest as 111.0㎝ and Suweon 19 was the shortest as 94.2㎝ at the third planting time. In the dry matter yield per ha, P3352, DK729 and P3144W were higher than the others as 18,957, 18,840, 18,743㎏, respectively, and P3282 was the lowest as 13,863㎏ at the first planting time. 64743 and P3352 were 18,183 and 17,874㎏, respectively, and Suwoen 19 was the lowest as 15,007㎏ at the second planting time. P3144W was the highest as 19,112㎏ and Suwnen 19 was the lowest as 14,793㎏ at the third planting time. The TDN yield per ha, of P3352, P3144W and DK729 were 13,552, 13,281 and 13,252㎏, respectively, and P3282 was the lowest as 9,793㎏ at the first planting time. 64743 and P3352 were higher than the others as 13,149 and 13,009kg, respectively, and Suwoen 19 was the lowest as 10,872㎏ at the second planting time. P3144W was the highest as 13,521㎏ and Suwven 19 was the lowest as 10,392㎏ at the third planting time.

To determine effects of sire group and sire`s birth year on body measurements of Korean native calves, the data set from 276 heads of Korean native calf raised at National Animal Breeding Institute from 1981 to 1990, was analyzed. The sire groups were subdivided into performance tested, championship contested, and general sire groups, respectively. The effects of sire`s birth years on the calves growth were significant in body length, withers height, chest width, hip width and thurl width at birth, and in body weight, body length, withers height, chest girth, hip width and thurl width at 6 months after birth. On the calves growth, the effect of the championship contested sire group was much more evident than those of the other sire groups. Body lengths and chest widths at birth and 3 months after birth fluctuated greatly by sire`s birth year. However, at 6 months after birth, the phenotypic gain of the all traits were distinctive.
