The objective of this study was to investigate the effect of dietary supplementation of blood meal as a source of L-histidine, and the addition of magnesium (Mg) as a catalyst of carnosine synthetase for the carnosine and anserine concentrations of pig muscles (longissimus dorsi, LD and vastus intermedius, VI). A total of twenty-four pigs with an average body weight of $60.2{\pm}4.2$ kg were randomly allotted to one of three dietary treatments (eight replicates), during 56 d of the feeding trial. Dietary treatments included: (1) Basal: basal diet; (2) BM: 95% basal diet + 5% blood meal; and (3) BM+Mg: 94.8% basal diet + 5% blood meal + 0.2% MgO (60% Mg). Results indicated that drip loss in the LD was less (p<0.05) for meat with BM+Mg treatment than that with Basal treatment, but the values for BM treatment did not differ from those of the other two treatment groups. The concentrations of carnosine in the LD were increased by 10.0% in both BM and BM+Mg treatment groups over the Basal treatment group (significance not verified). The concentrations of carnosine and anserine in the VI were not affected by the dietary treatments. Inclusion of additional Mg in diets had no effect on carnosine and anserine concentrations in the LD and VI. In conclusion, dietary supplementation of blood meal could be a potential method of fortifying the pork with carnosine. Inclusion of additional Mg in the diets containing blood meal had no benefit on carnosine and anserine depositions in pig muscles.

This study was done to investigate the effects of the incorporation of Achyranthes japonica extracts (AJE) in diet on the production parameters of growing pigs. Exp 1: Total, 105 crossbred pigs (average body weight: 24.47 ± 2.46 kg) were used in a 6-week feeding trial. Pigs (seven replicates, five pigs per pen) were allotted randomly to three treatments. Dietary treatments: CON (basal diet); basal diet with 0.025% AJE, and basal diet + 0.050% AJE). Growth performance, nutrient digestibility, fecal microbial count, and fecal noxious gas were assessed in this study. Average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G:F) were not affected by the addition of up to 0.05% AJE. In the case of apparent total tract digestibility (ATTD), dry matter (DM), nitrogen (N), and digestible energy (DE) were not changed in 3rd and 6th weeks of the feeding trial through the addition of AJE up to 0.05% in the growing pig diet. In microbial count, Lactobacillus and Escherichia coli count at 3rd and 6th week was similar in all the treatment diets. The inclusion of AJE at levels up to 0.05% in growing pig diet had no effect on the production of NH3, H2S, acetic acid, and CO2 in the feces. After ending the Exp 1, a total of nine pigs were divided into three treatment groups. Treatment diets were included, TRT1, basal diet + powder quercetin 30 g; TRT2, basal diet + powder quercetin 150 g; TRT3, basal diet + powder quercetin 300g. Rate of absorption in blood was increased with the higher dose of quercetin. The results suggested incorporation of AJE up to 0.05% has no significant effect on ADG, ADFI, and G:F, as well as DM, N, and DE digestibility, fecal microbial count, and fecal noxious gas emission in growing pigs, even though no negative effect was found.

Objective: The current study aimed to replace soybean oil in broiler diets with linseed oil, which is rich in omega-3 fatty acid supplemented with pomegranate peel extract (PPE) and measured its effect on broiler performance, carcass traits, lipid profile, as well as fatty acids composition, phenols and flavonoids content of broiler muscles and immunity of broiler chicks. Methods: A total of 300 1-day-old Cobb chicks were randomly allotted into six experimental groups, T1 fed on basal diet with soybean oil without any additives, T2 fed on basal diet with soybean oil with addition of 0.5 g/kg diet PPE, T3 fed on fed on basal diet with soybean oil with addition of 1 g/kg diet PPE, T4 fed on basal diet with linseed oil without any additives, T5 fed on basal diet with linseed oil with addition of 0.5 g/kg diet PPE and T6 fed on basal diet with linseed oil with addition of 1 g/kg diet PPE. The PPE supplementation with 0.05% improved final body weight with either soybean oil ration or linseed oil ration. Results: The PPE improved carcass dressing percentage in comparison with the control groups. Body fat levels decreased with increasing PPE levels, especially with a linseed oil diet. Replacing soybean oil with linseed oil decreased the total cholesterol and triacylglycerol levels in broiler serum. The PPE supplementation decreased serum total cholesterol levels and increased high-density lipoprotein cholesterol levels. The content of the breast muscle alpha linolenic acid improved after replacement of soybean oil with linseed oil in broiler diets. PPE supplementation increased the phenol and flavonoid content in broiler meat and increased lysozyme activity. Conclusion: Replacing soybean oil with linseed oil in broiler diets with the addition of PPE enriched muscle meat with omega-3 fatty acids and antioxidants and improved broiler immunity and their serum lipid profile.

Objective: The objective was to evaluate feed intake, digestibility, body weight change and carcass characteristics of sheep fed a basal diet of hay supplemented with banana leaves and silver leaf desmodium. Methods: Thirty yearling lambs with an average initial body weight of $15.85{\pm}1.6kg$ were grouped into six blocks of five rams in each block. The treatments were: hay alone (T1), hay+100% banana leaf (T2), hay+67% banana leaf+33% desmodium leaf (T3), hay+33% banana leaf+67% desmodium leaf (T4), andhay+100% desmodium leaf (T5). Three hundred grams of treatment diets were offered daily on as fed basis. The feeding and digestibility trials lasted for 84 and 7 days, respectively, followed by carcass evaluation. Results: The total dry matter (DM) intake for T3, T4, and T5 were greater (p<0.05) than those fed T1 and T2 diets. The lowest (p<0.05) organic matter (OM) intake was recorded in rams reared on T1 diet. The total crude protein (CP) intake was in the following order: T5>T4>T3>T2>T1. Ram lambs receiving supplementary diets had higher (p<0.05) DM, OM, CP, neutral detergent fiber and acid detergent fiber digestibility compared with the control diet. The empty body weight and slaughter weight was highest (p<0.05) in rams receiving T3, T4, and T5 diets. The average daily gain and feed conversion efficiency was highest (p<0.05) in rams receiving the supplementary diets. The dressing percentage on the basis of hot carcass weight linearly increased with increasing levels of desmodium. Rams reared on supplementary diet had higher (p<0.05) rib eye area compared with the control diet. Conclusion: In conclusion, when banana leaf is used as a supplement to poor quality grass, better body weight gain was obtained when fed in combination with desmodium.
The effects of thiamin on vegetative mycelial growth and fruit body formation of Lentinuia edodes were investigated in basal peptone-glucose liquid medium in relation to the uptake of thiamin. Thiamin was essential for fruit body formation, and the minimum requirements for thiamin were estimated to be approximately 10 ${\mu}g$/L. The vegetative mycelial growth was little influenced by the addition of thiamin in the range of 1.5 ${\mu}g$~1.5 mg/L. While the mycelium was successively transferred to fresh peptone-glucose-agar medium three times, the repression of mycelial growth was not significant. Even in cases using vitamin-free casamino acid or glutamic acid as a nitrogen source instead of peptone, a thiamin deficiency for mycelial growth did not occur as a result of transferring the mycelia to fresh media. Almost all of the thiamin contained in the media accumulated in the mycelia during the first 3 weeks of a 9-week incubation. These results suggest that only trace amounts of thiamin are required for vegetative mycelial growth in Lentinula edodes and that almost all thiamin added to a basal medium will be used for fruit body formation.

The early life history of Silurus microdorsalis living in Jahocheon Stream was studied by observing egg and morphological development. Live fish were captured in June 2018, then reared in a circulating filtration system under a 14L : 10D photoperiod with a water temperature of 18℃. To artificially induce spawning, females were injected with 0.5 mL of Ovaprim (Syndel, Nanaimo, BC, Canada) per kg of body weight, and males were injected with 10,000 IU/kg body weight of human chorionic gonadotropin. Approximately 15 h later, eggs were artificially inseminated by the dry method. Mature eggs were light pale yellow, which separated them from immature eggs. Fertilized eggs were 2.16±0.06 mm (n=8) in diameter and fully hatched at 181 h after fertilization. The fertilization rate was 63.1±2.2%, and 10.0±3.7% of the embryos were malformed at 18℃. The rates of development were 181 h at 18℃, 109 h at 21℃, and 76 h at 24℃. The larval size immediately after hatching was 4.64±0.22 mm (n=8), and the larvae displayed negative phototaxis at 1 day after hatching. The total larval length on 7 days after hatching was 12.47±0.53 mm, with 25~30 basal anal fin rays and 14~16 basal caudal fin rays observed. The total larval length was 14.13±0.51 mm on 9 days after hatching, and approximately 90% of the black endoplasmic reticulum was deposited on the head and body. The dorsal fin had formed, and a single basal body was observed. On 15 days after hatching, the total larval length was 16.69±0.31 mm; the number of basal caudal fin rays (18 poles) was an integer because 2 dorsal fin basal rays and 60~63 anal fin basal rays were observed. The total larval length was 28.96±1.10 mm on 50 days after hatching; the numbers of caudal fins (n=18), dorsal fins (n=3), pectoral fins (n=11), and anal fin basal rays (n=67~73) were integers.

Purpose : Man is a homoiothermal animal. But by various causes, body temperature can be changed to $1^{\circ}C$. Basal temperature is a very useful method in many fields of OB&GY area. So we observed the change of body temperature according to menstrual cycle. Materials and Methods : We observed 3 female who have very regular 30 days menstrual cycle. The Observation started before the onset of menstruation and body temperature was checked in the same time (11:00 am) of a day. To evaluate the change of body temperature, we examined three points of body. And to observe the body temperature we used the D.I.T.I(Dorex, Inc., USA). Results : On this study we couldn't find the typical biphasic change of body temperature but most of the materials showed the elevation of body temperature on the 14th day. Between the examined three points, the lowest point was showed more typical biphasic change of body temperature.
Purpose In Sasang Constitution Medicine, persons are divided into four types such as Taeyangin, Taeumin, Soyangin and Soeumin according to their appearance, moral nature and characteristic of constitutional symptoms. In teenager group, diagnosis of constitution based on their appearance was so difficult that we adopted new diagnostic method which measures and compares body compositions. Methods 180 middle school students who live in Pusan were studied from 20th of March, 1999 to 20th of March, 2000. After practicing Questionnaire(I), QSCC(Questionnaire of Sasang Constitution) I , QSCCII, we have measured the height and body compositions with Inbody 3.0, five times. Results 1. The results of Sasang Constitution analysis showed 91 students were classified as Taeumin(50.3%), 75 as Soyangin(41.4%), 14 as Soeumin(7.7%), and 1 as Taeyangin(0.6%). 2. The level of total body water, muscle area, BMR(Basal Metabolic Rate), BCM(Body Cell Mass), and AMC(Arm Muscle Circumference) were increased during spring and summer. That of body weight, fat body weight, fat body weight ratio, waist hip ratio, and BMI(Body Mass Index were increased during fall and winter. 3. In Taeumin and Soyangin groups, the changed capacity of total body water, muscle area and BMR were increased with statistical significance. 4. Waist hip ratio of Soeumin group was reduced more than those of Taeumin, Soyangin groups with statistical significance.
The purpose of this study was to investigate the effects of modified fasting therapy using Gamrosu and herbal medicine on the changes of body compositions in women. We analyzed the medical records of 11 patients, who carried out modified fasting therapy at Dunsan Korean Medicine Hospital of Daejeon University. Body compositions (body weight, body mass index, body fat mass, skeletal muscle mass, basal metabolic rate, extracellular water ratio, abdominal circumference, thickness of abdominal subcutaneous fat, visceral fat area) were reviewed before and after modified fasting therapy. The body composition values (body weight, body mass index, body fat mass, skeletal muscle mass, basal metabolic rate, extracellular water ratio, abdominal circumference, thickness of abdominal subcutaneous fat, visceral fat area) decreased after modified fasting therapy. Results from this investigation showed that modified fasting therapy using Gamrosu and herbal medicine has positive effects on changes of body compositions.
This experiment was designed to observe some influence on the serum components of growing rats maintained with basal diet supplemented with sausage. Forty male Albino rats were used as the experimental animals and the subjects were divided into four diet groups (control group; feeding of basal diet containing 10.8% and 10.4% of protein and lipid respectively, A group; feeding of sausage containing 12.5% and 27.6% of protein and lipid respectively supplemented with basal diet every day, B group; feeding of sausage supplemented with basal diet once a three-day and C group; feeding of sausage supplemented with basal diet once a five-day) and each group was fed on the corresponding diet for forty-days. The contents of protein, lipid and cholesterol in their serum were determined. The result obtained are summarized as follows: 1) The final body weight and liver weight of the A group were increased more than other groups. 2) The protein contents in the serum of the B group was increased more than other groups. 3) The total lipid contents in the serum of the A group and B group were decreased compared with control group. 4) The total cholesterol, ester form cholesterol and free form cholesterol in the serum of the A group were decreased, but the total cholesterol and ester form cholesterol in that of the C group were increased compared with control group.
