This study used fowl sperm from three White Leghom rooster reared at our laboratory. Semen samples were exposed to the magnetic field strengths of from 650 to 5700 Gauss for one. two, or three days to investigate the influence of magnetic field on the orientation of fowl spermatozoa. Fowl spermatozoa were found to orient with their long axis of heads perpendicular to the magnetic field direction. The fowl spermatozoa were initially influenced when magnetic field intensities were from 650 to 5700 Gauss and the highest values (70.67, 72.49 and 71.79%) were found in the 5700 Gauss treatment at one, two, and three days exposure, respectively. Although percentages of the perpendicular oriented fowl spermatozoa increased along with the enhancement of the magnetic field intensity, the degree of orientation was only significantly higher in the treatments having the magnetic field strength from 1500 to 5700 Gauss than that in the control treatment at all exposure time. In addition, the experimental results also showed that the percentages of all orientational types of fowl spermatozoa (perpendicular category including upward perpendicular and downward perpendicular and parallel type consisting of leftward parallel and rightward parallel) in all treatments tended to be stable during exposure time. From the results of this study. it is suggested that (1) the diamagnetic anisotropy of the inside structural components of fowl spermatozoa induce them to orient perpendicular to the magnetic field direction, (2) the degree of orientation increased according to the enhancement of magnetic field strengths, (3) fowl spermatozoa had not an high sensitivity to the magnetic field, and the level of perpendicular orientation of fowl spermatozoa in this study is nearly similar to that of cattle sperm in the study of Suga et al. (2000).
True amino acid availability (TAAA) and true metabolizable energy(TME) values of 8 protein feedstuffs were determined by feeding three roosters exactly 30g of each protein feedstuff after 36h of fasting. From each rooster excreta were collected for 36 h. TAAA were significantly(P<0.01) different among protein feedstuffs. TAAA was highest in fish meal(96.1%), followed by corn gluten(91.2%), rapeseed meal(88.8%), soybean meal(88.7%), meat meal(87.2%), canola meal(86.1%), cottonseeed meal(82.6%) and feather meal(82.5%). Available Iysine values obtained by TAAA method were highly correlated(P<0.01) with those obtained by chick bioassay(CBA) and FDNB method. TME was highest in corn gluten(4,011kcal/kg, as fed basis), followed by fish meal(3,906), feather meal(3,098), soybean meal(3,007), meat and bone meal(2,631), canola meal(2,326), cottonseed meal(2,246) and rapeseed meal(2,120).
An experiment was conducted to compare the ME values of imported corns measured by In vivo(TME) and In vitro(MEn, ME and MEpc) methods and to investigate the true amino acid availability(TAAA) and the true nutrient availability(TNA) of imported corns. For TME assay, twenty four 57-weeks-old Hy-Line roosters were assigned to fasting group(4 roosters) and four corn groups(5 roosters each): USA; corn produced in the United States, ARG; corn produced in Argentina, CHN; regular corn produced in China, CHNP; premium corn produced in China. The MEn, ME and MEpc values were determined by equations based on chemical analysis. The TME value of USA(3,745kcal/kg) in as fed basis was significantly (P<0.01) higher than ARG(3,555kcal/kg) and CHNP(3,518kcal/kg) but was not significantly different from CHN(3,671kcal/kg). The TME value of USA(4,144kcal/kg) in DM basis was not significantly different from CHN(4,060kcal/kg) and CHNP(4,008kcal/kg) but was significantly(P<0.05) higher than ARG(4,001kcal/kg). There were significant differences in TAAA of phenylalanine, histidine and arginine among imported corns. Those of USA were highest but overall TAAA was not significantly different among imported corns. True availability of NFE of USA, ARG and CHN was significantly(P<0.05) higher than that of CHNP. However, true availability of crude protein, crude fat, crude fiber and crude ash were not significantly different among corns. The correlation coefficient between TME and MEn value was 0.91 which was significant at P<0.1 but correlation coefficient between TME and ME value and between TME and MEpc value was 0.90 and 0.83, respectively which was not significant at P<0.1. In conclusion, US corn was highest in TME values and Chinese premium corn was not significantly different from regular Chinese corn. The MEn value obtained by equation based on chemical analysis may be used as a tool to evaluate TME value of corn.
Three trials were conducted to determine the available energy of different wheat screening varieties collected from different locations of Khorasan in Iran. In experiment 1, chemical composition and the nitrogen corrected true metabolisable energy (TMEn) were evaluated. A precision-fed rooster assay was used, in which, each wheat screening sample was tube fed to adult roosters, and the excreta were collected for 48-h. In Exp. 2 and 3, five and two wheat screening verities-based diets with or without xylanase and phytase were fed to 16-day old battery reared chicks respectively, and total feed consumption and excreta were measured during next three days. The variable nature of wheat screening varieties led to significant differences in mean TMEn values (p<0.01). The TMEn values of samples determined with adult roosters varied by ${\pm}5.03%$ of the mean value ($3,097.65{\pm}49.32\;kcal/kg$) and ranged from 2,734.90 to 3,245.12 kcal/kg. There was a significant correlation (p<0.05) between crude fiber (CF), neutral detergent fiber (NDF), and acid detergent fiber (ADF) with TMEn, and the greatest correlation coefficient was observed between NDF and TMEn (r = -0.947; p<0.001). The optimal equation in terms of $R^2$ from using a single chemical analysis was obtained with NDF: TMEn = 4,152.09-27.80 NDF ($R^2$ = 0.90, p<0.0001), and the TME prediction equation was improved by the addition of the crude protein (CP) and ASH content to sequential analysis: TMEn = 3,656.97-28.65 NDF+32.54 CP+38.70 ASH ($R^2$ = 0.98, p<0.0001). The average AMEn values of 5 and 2 wheat screening varieties determined with young broiler chickens were $2,968.41{\pm}25.70\;kcal/kg$ and $2,976.38{\pm}8.34\;kcal/kg$ in Exp. 2 and Exp. 3, respectively. Addition of xylanase and phytase to wheat screenings resulted in significant (p<0.01) improvement in AMEn by 4.21 and 2.92%, respectively.
Fifteen 1-yr old roosters were employed in order to investigate the influence of various dietary fibers on the water and Na metabolism of chicken. Wheat bran, pure cellulose and ground rice straw replaced corn in the control diet at 10% level; Pectin replaced corn at 8% level. Three roosters were allotted per dietary treatment and one rooster per replicate. The limit of probability accepted as being significant was P$\leq$.05. The dry matter metabolizabilities of cellulose and rice straw diets were significantly lower, and those of control and pectin diets were significantly higher than that of the wheat bran diet. Pectin fed roosters seemed to drink more water than did the other birds. Also, excreta from roosters fed the pectin diet were significantly wetter than those from other treatments. However, no difference in water intake and fecal moisture were found when !he roosters were colostomized. It was also found that the colostomized birds drank more water than did intact ones. Data of water holding capacity and bulk density of dried excreta showed that cellulose, rice straw and wheat bran in decreasing order were strong in fibrous property. There were no significant differences in C$_{Na+}$ , Cosm and C$_{{H_2}O}$ among all treatments. When the values of urine volume, urine osmolality and C$_{{H_2}O}$ were put together, it can be concluded that 11 out of 15 roosters developed diuresis. More severe diuretic symptoms were developed in roosters when they were fed more fibrous diets. In conclusion, when the four dietary fibers were graded in terms of fibrous property, it turned out to be pectin, cellulose, rice straw and wheat bran in decreasing order.
This study was performed to analyze the generational transmission and the expression of the foreign gene in the GFP transgenic chickens. The transmission rate and the expression of the GFP gene was investigated from the GFP transgenic rooster (G2) as the first founder to the ninth (G8). Analysis of GFP expression in hatched chickens was used the UV lamp. When GFP was expressed in the wings, bill and legs of a chick, the bird only was selected as a transgenic chick. The average transmission rate of the overall transgenic was 38~58%. These results showed that the transmission of the GFP gene in the transgenic chickens in accordance with the laws of Mendel's continues to the next generation without gene silencing.

According to Korean's geographical features of Taek Li Ji, the best location for human settlements is on the vicinity of a stream among a stream, an river and a sea, and not far from a ridge. The researcher chose one of best village which is called Yougokmaeul in Bonghwa-Gun, Kyungsang-Do. This village was created a gathering village with the same surname, can be translated as a hen and the front mountain can be seen as a rooster in the view of the shape of geographical features. As it were, the shape of this village and the cultivated land seems to be an egg inside a nest of a parent's chicken in the respect of the analogy of the theory of P'ungsuchiri which is known as Feng Shui in China and geomancy in the western world, and to effect the defensive psychology of the living environment in the terrain inland. This village is the studying place, Suckchunjungsa as the lecturing and studying place for their following students within the Chunghadonchun, the studying Yougok village, and even the ritual place performing ancestral sacrifices and the first incoming ancestor's graves in the same geographical system. The house site of the first incoming resident is surrounded the countian and is located in the front of Backsulryount which is the main mountain through Moonsu-san in the branch mountain of Korean's mountain system. Backsulryoung which is to be seen as the white peak, is symbolized the head of a hen which is to relate to a mysterious turtle in the view of P'ungsuchiri. And the pavilion which is called Chungamjung is sited on the rock of a shape of turtle which is symbolized to live longer. In the section of the mountain and water, Lee Jung Hwan mentioned a living place near the mountain stream is the best residential area and a landscape which is composed by a stream between mountains make a pleasure spirit and a bright feeling and make a refined person. If one can reach in the graceful mountain make a pleasure split and a bright feeling and make a refined person. If one can reach in the graceful mountain half day away, this kind of place must be a best living residential area to live. But this village was structured all in one place. And one of the ideas tangibly reflected in traditional Korean society's view of life and nature is the seclusion based on the Taoism. This kind of a dreamy thoughts make a dream to keep the paradise in our ancestors' mind. This kind of utopia is Chunghadonchun which is structured 5 aspects from the utopian gate near the Samgaesuewon to the village. These 5aspects is expressed by some Confucian thoughts as a small cosmos individually. On the third aspects which is the center among these aspects, the Suckchunjungsa which was made a seclusion place to devoting himself to his studies with refined tastes. The word of Jiju-am, Gangpung-dae, Jaewol-dae and Biryoung-pock are all expressed to cultivate one's moral character and to seek the truth by the Confucius'theory through the nature.
The study was carried out to examine factors affecting metabolic plus endogenous one.9y (FEm+UEe) losses by adult roosters. Experiment one was performed to examine the effect of excreta collecting period and Experiment two, of feeding soluble carbohydrates (corn starch and glucose) to birds on FEm+UEe losses. The results obtained were as follows : 1. The excreta voided, energy and energy losses by the roosters during collecting period II (24-48hr) were generally higher than those of period I, at though there was no significant difference (P>.05). 2. There was not found correlationship between body weight (X) and excreta voided, energy and nitrogen losses IY) (P>.05). The fact supported that body weight of birds did noy affect the losses of FEm+UEe by adult rooster. 3. The feeding of glucose and mixture (corn starch+glucose) decresed excreta voided, energy and nitrogen losses significantly (P<.05) comparing with those of unfed birds. 4. The excreta voided, and nitrogen loss of birdsfed corn starch were much lower thu those of unfed birds. Fact that FEm+UEe losses was not significantly different (P>.05) between birds fed corn starch and unfed birds was indicative that apparent digestibility of corn starch was much lower than that of glucose ana mixture. 5. Nitrogen loss of fed birds was greatly reduced comparing with that of fed birds. The finding was indicative that the carbohydrates input was ultilized to supplemented energy loss through the catabolism of body tissue during fasting.
An experiment was conducted to study the effects of nicarbazin supplementation (125 ppm) on the water balance, blood acid-base balance, and rectal temperature of 16 SCWL adult roosters in normal($21^{\circ}C$) and hot(35~$36^{\circ}C$) temperatures. There were 4 d of preliminary period, followed by 2 d of sampling and data collection period for each temperature treatment. The amounts of DM intake and excretion were not affected by heat stress but by rucarbazln supplementation. The DM metabolizability of diets, however, was decreased by nicarbazin. The amounts of water intake and evaporative water loss were increased in heat stressed birds. Nicarbazin increased further the amounts of water intake and evaporative water loss in hot temperature. Nicarbazin also decreased the blood p$CO_2$ and increased blood pH of heat stressed birds. The rectal temperature of the bird was increased in hot temperature, and the nicarbazin supplementation worsened this effect. Results indicate that heat stress raises the body temperature of the chicken. In order to suppress the rise of body temperature, the birds enhance the evaporative water loss through panting. The nicarbazin supplementation to heat stressed birds, however, increases the body temperature to such an extent that panting alone may not be able to return the body temperature back to normal.
Foxtail millet (Setaria italica L. Beaur) is a native Korean herbal medical food and a native millet, and Koreans have eaten it as a substitute for rice since ancient times. Foods using foxtail millet (Setaria italica L. Beaur) have been recorded not only in cookbooks but also in Korean traditional medical books several times. Therefore, the purposes of this study was to investigate Food-Therapy (食治) using foxtail millet (Setaria italica L. Beaur) recorded in the literature from 1300 to 1600 from early to mid-Joseon (朝鮮) and provide data required to develop menus for Yaksun (藥膳, herbal food). This study examined Food-Therapy using foxtail millet (Setaria italica L. Beaur) in 10 types of literatures from the 1300s to the 1600s. and is described in the literature a total of 63 times. According to classification by cooking method, porridge (粥) was most frequently mentioned in the literature at 27 times. The cooking method of Soup (湯) is described 11 times. Cooking methods such as porridge juice and soup are frequently used since those methods are digestive and absorptive. Other food ingredients described using foxtail millet (Setaria italica L. Beaur) are white leek (Allii Fistulosi Bulbus) ginger (Zingiber officinale), chicken egg, Allium chinense, sparrow (Passer montanus), rooster liver, Du-si, crucian carp (Carassius auratus L), and white broiler. Other medicinal herbs described with Setaria italica are Panax ginseng (人蔘), Poria cocos (茯笭), Angelica acutiloba (當歸), Ziziphus jujuba (大棗), Liriopeplatyphylla (麥門冬), and cinnamon (肉桂). Food-Therapy using Setaria italica L. Beauv was described as a prescription for stomach and spleen (脾胃), stomach reflux (反胃), defecation and urinary disorder (大小便難), cholera, deficiency syndrome (虛症), and tonification (補益). This focus on promoting health and preventing diseases by strengthening the stomach and spleen and improving defecation and urination using Food-Therapy when herbal medicine was rare.
