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.

This research was carried out to determine the quantity and characteristics of broiler excreta produced in different age and different types of broiler house. Daily feed intakes of broiler chicks ranged over 160.1~165g/d in the sixth week of age. Female and male broiler consumed 211.3 and 252.9 $m\ell$/d of water in the period, respectively. The amount of excreta produced by female and male broiler was 164.3 and 176.3g/d/bid in the sixth week, but average daily excreta production from birth to the sixth week of age was 90.5g/bird. Accumulated excreta production of broiler per bird in the sixth week was 3,800g. The contents of N, $P_2O_5$ and $K_2O$ in broiler excreta were 4.49, 1.28 and 2.02% in DM basis, respectively. The average moisture contents of litter produced from windowless broiler house, open-sided and vinyl house type broiler house were 18.3, 29.7 and 30.1%, respectively.

A 2 ${\times}$ 2 factorial experiment was conducted to determine the effect of cecectomy and urea supplementation on nitrogen utilization In growing chicks. Birds were either cecectomized or shamoperated and fed a 19% protein diet with or without 1% urea supplementation. All chicks were provided ad libitum access to feed and water throughout the six-day experimental period. In the cecectomized chicks, fred efficiency was significantly decreased when fed a 19% protein diet supplemented with 1% urea (P<0.05). When chicks were fed a 19% protein diet, cecectomy significantly shortened gastrointestinal passage time (GPT) of food (P<0.05). However, the GPT was significantly lengthened in chicks fed a 19% protein diet supplemented with urea (P<0.05). Regardless of diets, cecectomized chicks increased the moisture contents of the excreta (P<0.05) and feeding a 1% dietary urea also significantly increased (P<0.05). Cecectomy significantly decreased uric acid N excretion by about 30 mg per 100 g body weight per day (P<0.05) and uric acid N/ total N excretion when fed both diets (P<0.05). The present study suggests that cecectomy improves nitrogen utilization rate by decreasing uric acid excretion in growing chicks. These results are in good agreement with those obtained previously in a cecectomy study of adult chickens.

This research was carried out to determine the quantity and characteristics of layer excreta produced in different age and different types of layer house. Daily feed intakes in the growing stage were 60.8 and 92.9g/d the 6th and 12th week of age, respectively. Daily feed intakes in the early laying stage (19th wk of age) and the ending period of laying(55th wk of age) were 105.1 and 122.0 g/d, respectively. A laying hen consumed 193.1~222.5$m\ell$ of water per day. The amount of excreta produced by laying hen were 143.3~144.8g per day. The moisture contents of excreta produced by laying hen ranged over 74.7~80.5% in laying period. The average contents of N, $P_2O_5$ and $K_2O$ in layer excreta were 4.88, 1.92 and 1.71% in DM basis, respectively. In the laying period, CaO contents of excreta were 7.42~9.02%. The moisture contents of excreta produced by windowless poultry house, open-sided poultry house applied mechanical ventilation and open-sided poultry house applied natural ventilation were 65.4, 75.7 and 81.3% in summer, respectively.

The maintenance of the osmolality of body fluids within a very narrow physiologic range is possible by water balance mechanisms that control the intake and excretion of water. Main factors of this process are the thirst and antidiuretic hormon arginine vasopressin (AVP), secretion regulated by osmoreceptors in the hypothalamus. Body water is the primary determinant of the osmolality of the extracellular fluid (ECF), disorders of body water homeostasis can be divided into hypo-osmolar disorders, in which there is an excess of body water relative to body solute, and hyperosmolar disorders, in which there is a deficiency of body water relative to body solute. The sodium is the predominant cation in ECF and the volume of ECF is directly proportional to the content of sodium in the body. Disorders of sodium balance, therefore, may be viewed as disorders of ECF volume. This reviews addresses the regulatory mechanisms underlying water and sodium metabolism, the two major determinants of body fluid homeostasis for a good understanding of the pathophysiology and proper management of disorders with disruption of water and sodium balance.

Purpose: The purpose of this study was to compare the fluid intake and output (I&O) measurement methods in order to figure out more effective and easier method for medical patients Methods: 71 hospitalized patients participated in the study. In "liquid only (LO)" method, all amount of water was summed up including any liquid types of food and IV fluids. In "whole food(WF) intake," all liquid and solid food intake and IV fluids were added up. Results: The average amount of fluid intake was 2105.29 ml for LO method and 2523.54 ml for WF method. The average amount of fluid output was 2148.98 ml. The intra-class correlations (ICC) between the intake and output measures by the two different methods was 0.803 and 0.826, respectively. The correlation between the differences of intake/output and body weight change in two different methods was r=.347 (p=.003), and r=.376 (p=.001), respectively. Conclusion: The results of this study indicate that both LO and WF method may be useful in monitoring patients' fluid balance. Given the comparability of using LO over WF, it is suggested that measuring just liquid only intake as the indicator of patient's intake is applicable in clinical setting.

Seven-day-old 40 broiler chicks of both sexes were fed the conventional diet containing 0, 0.3, 6 and 0.9％ Quartz porphyry(QP) and water ad libitum until 28 days of age. The excreta water content and nitrogen balance were measured during the experimental period. At the end of the trial, blood samples were collected to measure ammonia, glucose, triglyceride, and total cholesterol concentrations. In addition, intestinal ammonia concentrations were measured. The excreta moisture contents decreased significantly(P < 0.05) as QP levels increased(r= -0.96). Ammonia contents in the intestine tended to increase as QP levels increased, but the ammonia concentration in the blood was not affected by the QP levels. The blood glucose concentration was not changed but blood triglyceride concentration was lower in the 0.3％ QP treatment than the other groups(P < 0.05), Total cholesterol concentration in the blood tended to increase as QP levels increased. The QP 0.3％ treatment showed somewhat higher positive N balance than the other groups. The results of this experiment indicate that the dietary supplementation of QP could offer some benefits to broiler growers.

This study was performed to investigate the influence of giant embryo feeding on hypoglycemia in streptozotocin-induced diabetic rats. Streptozotocin -induced diabetic rats were fed four kinds of experimental diets such as corn starch diet as a control, polished rice diet, brown rice diet and giant embeyonic rice diet for 6 weeks. The body weight gain diabetic of control was signaficantly suppressed compared to that of the normal. The supplementation of giant embryo increased the surivival rate. Feeding of giant embryo appeared to have ameliorating effects on diabetic symptoms including features such as polyphasia, polyuria. Giant embryo shortened gastrointestinal transit time and increased total fecal weight, total fecal dry weight and fecal water content compared with diabetic control. Giant embryo showed fasting blood glucose lowering effect compared with diabetic control. The disaccharidase activities in proximal part of intestine such as maltase sucrase and lactase in giant embryo feeding groups were lower than diabetic control. The results of this study show that giant embryo supplementation may have a beneficial Veffect on the hypoglycemia may be useful in the diet therapy for diabetic.

우리나라에서 계분은 귀한 비료로 사용되어 왔으며, 양계협회 능력검정소가 성북구 공릉동에 있을 때만 해도 주변의 배밭 주인들이 계분을 사기 위해 경쟁하였고, 계분판매 수입도 크지는 않지만 검정소의 수입항목이 되었던 것이 새롭다. 가축분뇨가 환경오염의 주범으로 양축농가가 구속된 때에도 닭의 경우는 다른 가축과 달리 총 배설강을 통해 분뇨가 혼합상태로 배설되므로 그 특성상 수분함량이 적어 큰 문제가 되지 않았었다. 그러나, 양계 규모가 커짐에 따라 주변의 민원과 절대적인 계분 발생량이 많아져 어떤 형태로든 처리하지 않을 수 없게 되었다.
