In this study, the effect of daily short-distance walking exercise on milk production and metabolic status of the lactating dairy cows was investigated. The experiment was conducted with 10 lactating dairy cows comprising 2 groups (5 dairy cows/group), which were walking activity and non-walking activity. The walking activity (WA) group lactating dairy cows walked outdoors for 1 km/d, and the non-walking activity (non-WA) lactating dairy cows were maintained within a cowshed from 18thApril to30th May. The activity volume of the neck was not significantly different between the groups, but the activity volume of the leg was higher in WA group compared with non-WA (p<0.05). The rectal temperature was higher in the WA group (38.6 ℃) compared with non-WA (38.2 ℃) (p<0.05). No significant differences in dietary NE intake, milk production and milk composition were found between the groups. The plasma cortisol concentration was higher in WA group (2.14 μg/dl) compared to non-WA (0.95 μg/dl) (p<0.05). However, plasma cortisol level of WA dairy cows was significantly decreased as compared with non-WA cows. On the contrary, the level of plasma melatonin was increased in WA cows than that of non-WA dairy cows. It may be interpreted as a change in physical fitness. From this study, we suggest that walking activity can be improved energy balance. Further investigation is needed to determine whether different combinations of distance, rate or doing in morning or afternoon will stimulate energy balance.

The purpose of this research was to investigate the relationship between white rice consumption and dietary intake, the risk of metabolic syndrome in Korean based on 1st (1998), 4th (2007~2009), 6th (2013) KNHANES. This study included 25,799 subjects who were age 10 or over. Three groups(low, medium, high) were divided according to white rice consumption (per day). In the low group, the meat and oil intake were significantly higher than the high group. In the 1st survey year, the BMI, waist circumstances, hypertriglyceridemia and fasting blood glucose in the high group were higher than other groups, however the 4th and 6th survey year showed no significant results. In the 1st survey year the risk of waist circumstances was higher in the high white rice consumption group and also had high risk with hypertriglyceridemia. Since the lower white rice consumption in 4th than 1st survey year we found no significant results. But in the 6th survey year with the lowest white rice consumption the risk of high diastolic pressure was reduced in high group. Because continuously reduced white rice consumption meantime showed more intake of meat and oil, it can be concluded that defensive effects with the Korean health.
