  • To determine the effects of dietary restriction on obese type 2 diabetes we measured body weight, blood glucose and serum lipid level in dietary restricted Otsuka Long Evans Tokushima Fatty (OLETF) rats. OLETF rats (obese diabetic rats) and LETO rats (control rats) were grouped into 3 groups; control (free feed) group, 20% dietary restricted (20% DR) group and 40% dietary restricted (40% DR) group. Body weight of rats was measured every weeks and the level of glucose, triglyceride (TG), total cholesterol (TC) and HDL-cholesterol in blood of rats were also determined at 12 weeks after dietary restriction. Body weight of control, 20% DR and 40% DR groups were increased by 41%, 20% and 10%, respectively in LETO rats and by 24%, 10% and -2%, respectively in OLETF rats. Blood glucose level of LETO rats were decreased by 12% on 40% DR compared to control group but the differences between control group and 20% DR group was not observed. The blood glucose level of OLETF rats were decreased by 20% in 40% DR group and by 15% in 20% DR group. The levels of blood triglyceride in 20% DR and 40% DR group were decreased by 20%, 15% in LETO rats and by 37%, 32% in OLETF rats, respectively Total cholesterol revel was not changed by dietary restriction in LETO rats, but significant changes were observed in OLETF rats by both 20% and 40% dietary restriction. HDL-cholesterol levels were also increased by dietary restriction in both LETO and OLETF rats. These results suggested that body weight and blood glucose, serum triglyceride and total cholesterol levels were decreased by dietary restriction and these changes are more susceptive in diabetic rats than non-diabetic animals.

  • 본 연구는 절식 및 재급여가 Sprague-Dawley 계통 수컷 흰쥐(55마리)의 지방조직내 LPL 활성과 지방합성량에 미치는 영향을 구명하였다. 아울러 재급여하는 동안 다양한 식이섭취 제한이 LPLghkf성과 지방합성에 어떻게 영향을 미치는 지도 조사하였다. 대조군(5마리)은 무제한 식이를 급여하였으며 실험 첫날 식이섭취 상태에서 바로 희생시켰으며, 그 외의 모든 쥐는 2일간 절식시켰다. 2일 절식 후 그중 5마리의 쥐를 희생하여 절식군으로 두었으며, 나머지 쥐(45마리)는 절식 후 식이를 재급여하였는데, 이때 재급여하는 동안 식이섭취 제한 효과를 보기 위해 ad libitum group, 20% food restricted group(ad libitum group의 80%) 및 40% food restricted group(ad libitum group의 60%)로 나누어 실시하였다. 재급여 후 7일, 14일 및 21일 째 되는 날 각각 희생하였다. 지방조직의 지방합성은 포도당이 총 지방으로 변한 양으로 측정하였다. 체중과 지방조직의 무게는 재급여 후 ad libitum group은 5일만에, 20% food restricted group은 14일만에 대조군 수준에 도달하였다. 재급여시 40% food restricted group의 체중과 지방조직의 무게는 재급여 후 21일째가 되도록 대조군 수준에 도달하지 못했다. 식이 재급여 후 21일 때 ad libitum group의 혈청 총 콜레스테롤함량은 대조군에 비해 높았다. (p<0.05). HDL-콜레스테롤함량은 재급여시 40% food restricted group가 대조군에 비해 높았다. (p<0.05). 그러나 HDL-C/TC비율과 중성지방함량은 처리군간에 유의적인 변화를 나타내지 않았다. 절식 후 지방조직내 지방합성량과 LPL(HR-LPL과 TE-LPL)활성은 대조군에 비해 현저희 저하되었다. (p<0.05). 재급여 후 21일째 ad libitum group의 지방합성량은 대조군에 비해 낮았다.(p<0.05). 그러나 40% food restricted group의 지방합성량은 대조군에 비해 높았다. (p<0.05). HR-LPL과 TE-LPLghkf성은 재급여시 ad libitum group과 20% food re-stricted group은 대조군 수준에 도달하였으나, 40% food restricted group은 재급여 후 21일째가 되도록 대조군 수준에 도달하지 못했다. 이러한 결과를 통해 절식 후 식이를 재급여할 경우 식이섭취 제한은 LPLghkf성이 증가되는 것을 부분적으로 혹은 완전히 예방할 수 있으며, 지방 조직내 지방축적에 영향을 미친다는 것을 말해 준다.

  • One of the challenging tasks of the National Health Insurance Corporation(NHIC). the only public insurance institution administrating the Korea's compulsory national health insurance(NHI) system, is to make those NHI beneficiaries who fail to make a scheduled monthly premium payment to pay. For this purpose, the NHIC has been using a measure known as 'Benefit Limit Measure(BLM)' in which those who miss premium payment for six or more month's in total are classified as 'late payer' and are sent warnings and late payer status notices. If the late payers fail to make a full payment of missed premiums even after receiving the written notices, the NHIC can order a temporary seizure of the late payer's property until all missed premiums plus interest are paid. Recently, the BLM has been criticized by the public of its cruel nature, and its effectiveness has been questioned because no empirical evidence has been collected. In this study, the authors using the NHIC data set attempted to analyze the effectiveness of the BLM. Those late payers for whom the BLM was administered were compared to those not in terms of the likelihood of paying missed premium payments with a series of logistic regression analyses models. Data analyses results showed that the likelihood of paying one or more month's unpaid premium of the former group was 14 to 46 times higher than the latter. It, however, was also found that the BLM was only effective to make no more than 12% of the late payers to pay at all. Based on the study findings, the authors made a few recommendations regarding the BLM.

  • This study examined the effects of restricted feeding on the growth performance, carcass characteristics, and economic efficiency of finishing pigs for 27 days. A total of 24 finishing pigs (Landrace×Yorkshire×Duroc, average initial body weight of 81.52±1.11 kg) were allotted randomly to two treatments with 12 replicates (one pig per replicate). The experimental treatments were ad libitum feeding (AF), and restricted feeding (RF) with a 10% increase in offered feed than the day before if required. The results showed that the average daily feed intake (ADFI; p<0.001) of the pigs were improved in the RF treatment, but there were no changes in the average daily gain and weight gain to feed intake ratio (G:F). There were no significant differences in carcass weight and backfat thickness. In addition, the total pork price per pig was not affected by RF. Although total feed intake (TFI) and total feed intake cost (TFC) were significantly lower in the RF pigs (p<0.001), the feed cost per 1 kg weight gain (FCG) was similar regardless of the treatments. In conclusion, the RF method may decrease the feed cost due to a lower TFI and TFC.

  • The objective of this study was to investigate the effect of restricted feeding to laying performance and egg quality in brown layers. A total of 1,080 brown layer chicks were divided into three treatments; conventional feeding (ad libitum) and two restricted feedings (80% of conventional diet) for 70 weeks. One of restricted feeding started from six to eighteen weeks of age, and the other started from twelve to eighteen weeks of age. Diets were formulated by NRC (1994) recommendation. Overall laying performance and feed intake were the highest in $6{\sim}18 wk$ restricted group. But there was no significant difference among treatment group (P>0.05). Feed intake was higher in $6{\sim}18 wk$ restricted group during maximum production (P<0.05), but there was no difference between treatments after the peak. Egg quality tended to decreased by aging, but there was no significant difference among the treatments (P>0.05). The result of present study indicated that restricted feeding in rearing period of layers is beneficial to improve egg productivity and to reduce feed cost.

Effects of Cecal Ligation and Colostomy on Food and Water Intake and loafer Excretion in Chickens Fed Restrictedly and Freely (닭에 있어서 사료섭취의 자유 및 제한급여시킬 때의 사료섭취량, 음수량 및 수분 배설량에 미치는 맹장결찰 및 인공항문 수술의 효과)

  • It was examined whether the ceca and the back-flow of urine into the lower intestine are involved in water intake and excretion in chickens and food intake affects those. Colostomy significantly increased water intake, total water excretion and the ratio of the water intake to food intake in the ceca-ligated chickens under restrict and ad libitum feeding conditions (P<0.05), but the increases were much larger in chickens fed ad libitum than in those fed restrictedly. Cecal ligation increased water intake, total water excretion and the ratio of water intake to food intake in the colostomised chickens which were fed freely (P<0.05). but not in those fed restrictedly, None of colostomy and cecal ligation affected the resultant water balances in chickens under both feeding conditions. Colostomy increased food intake in the ceca-ligated chickens (P<0.05), but no increase by cecal ligation was observed in colostomised chickens. It is concluded that the lower intestine takes a very important role in water recovery from urine to maintain water balance in chickens.

  • 성계편입전의 체중측정은 어떤 사료를 얼마나 급여할 것인가를 결정하여 줄 수 있으므로 정확한 기록은 올바른 산란계관리의 지침과 예고서가 될 수 있다. 또한 체중에 따라서 사료의 제한급이 여부나 제한량을 결정하는 것이 제일 확실한 방법이다.
