Feed flavor was added to whole milk and to calf starter to determine the effect of feed flavor on the starter consumption and growth of calves. Twenty four calves aged 4 days old were arranged randomized completely to 4 treatments and 6 calves per treatment. Calves received whole milk from birth to weaning at 46 days. Starter was offered ad libitum from day 12 to 46. Feed flavor was added to whole milk ar 120㎎/㎏ and starter at 0.1% Cowmilk Feednectar, 0.05% Sugarmate Feednectar and 0.05% Cowmilk Feednectar + 0.05% Sugamate Feednectar, and the results were summarized as follow: 1. Average birth weight of 24 calves was 42.77㎏ and the growth rate from birth to 46 days old was 0.353㎏ in average. 2. Average daily starter consumption from day 12 to 46 after birth was 310g in control group, 320g in Cowmilk Feednectar, 306g in Sugarmate Feednectar and 319g in Cowmilk Feednectar + Sugarmate Feednectar, respectively. 3. Average dally growth rate of calves from 12 to 46 days old was 417g in control group, 4918 in Cowmilk Feednectar, 4348 in Sugarmate Feednectar and 4378 in Cowmillc Feednectar + Sugamate Feednectar, respectively. Calves received feed flavor in starter gained more weight than those not fed feed flavor. 4. Addition of feed flavor in whole milk encouraged slightly to eat more starter which also contained same feed flavor.

This study was conducted to examine nutrient intake status and iron food sources by dietary iron density of high school girls in Seoul. The subjects of 226 girls were divided into High group (≥ 6 ㎎/1,000 ㎉, N = 115) and Low group (< 6 ㎎/1,000 ㎉, N = 111) by dietary iron density. The nutrient intake data obtained by 24-hour recall method were analyzed by Can pro 3,0 software. Mean age of all subjects was 16.4 years old, heights and weights of High group and Low group were 164.5 ㎝, 53.4 ㎏ and 161.7 ㎝, 51.7 ㎏, respectively. The body mass index (BMI) of High group and Low group was 20.5 ㎏/㎡ and 19.8 ㎏/㎡, respectively. Most nutrient intakes except energy and lipid intakes of High group were higher than those of Low group. High group showed significantly higher intakes of total iron, vegetable iron and animal iron than Low group. Ca and folate intakes of High group were under 75% of the recommended intake (RI) and Ca, iron, folate and vitamin C intakes of Low group were under 65% of RI. The percentage of subjects who consumed iron less than estimated average requirements (EAR) were 40.0% in High group and 77.5% in Low group. Total food intakes of High group showed higher than that of Low group. Total animal food intakes were significantly higher and total vegetable food intakes were significantly lower in Low group than those of High group. Iron intake from meats, fishes, shell fishes and seasonings were significantly higher in High group than Low group. Iron intake from milk and dairy products were significantly lower in High group than Low group. Major food sources of iron were rice, bean curd, pork, and egg in order among both groups.
