  • A feeding experiment was conducted to determine the use of distillers dried grain (DDG) as a partial replacement for fish meal in the diet for juvenile rockfish, Sebastes schlegeli. Four iso-nitrogenous (50% crude protein) and iso-caloric (4.3 kcal/g) diets (designated as DDG0, DDG7, DDG14, and DDG21) were formulated to contain 0, 7, 14, and 21% DDG. Triplicate groups of juvenile rockfish (initial body weight, $10.2{\pm}0.2g$) were fed one of the experimental diets to visual satiety twice a day (09:00 and 17:00) for 8 weeks. At the end of the feeding trial, survival of rockfish was above 97% and not affected by dietary DDG levels (P>0.05). Weight gain, feed efficiency and daily feed intake of juvenile rockfish were significantly decreased with increase of dietary DDG levels (P<0.05). Condition factor, hepatosomatic index and visceralsomatic index of juvenile rockfish were not significantly affected by dietary DDG levels (P>0.05). No significant differences were observed in the contents of moisture, crude protein, crude lipid and ash of the whole body and dorsal muscle in juvenile rockfish fed the experimental diets (P>0.05). Therefore dietary inclusion of DDG as a replacement for fish meal could depress the growth of juvenile rockfish.

  • Three groups of 7, 8 and 8 barrows (22 weeks age; 35 kg body weight), reared on grower diets were fed ad libitum on three isonitrogenous finisher diets containing 50, 71 and 92% wheat bran by replacing maize grain till the attainment of about 74 kg slaughter weight. Growth pattern, average daily gain, feed intake, feed/gain ratio and carcass traits were similar in all the groups. The digestibility of DM, OM, CF, NFE total carbohydrate and energy (DE) decreased (p<0.01) with the increased level of wheat bran in the diet. However, CP digestibility was comparable among all the diet and the digestibility of EE was significantly (p<0.01) higher in grainless diet ($FD_3$). It appears that maize grain may be completely replaced with wheat bran in the diet of crossbred pigs without any adverse effect on their performance with respect to feed intake, body weight gain and carcass characteristics.

  • Sixtyfour Baluchi lambs about 5 months of age were divided into four groups with 16 lambs each. All the animals were grazed together. Group No.1 (G-1) was kept as control i.e. on grazing only; while group No. 2 (G-2) was offered barley grain @ 200 g/head/day as supplement to grazing; Group No. 3 (G-3) was offered ad-lib urea-molasses block (UMB) with 6% cement and group No.4 (G-4) was fed ad-lib IMB having 8% cement. These UMB were fed as supplement to grazing. Experiment lasted for 105 days (July to October) in arid zone of Baluchistan. Daily per head consumption of block No.1 was found to be 92.71 g; while that of block No.2 was observed to be 90.77 g. Growth rate (g/head/day) was found to be 10, 50, 33 and 15 in G-1, G-2, G-3 and G-4 respectively. Expenditure/kg bodyweight gain was found to be rupees 12.00, 3.64 and 7.74 for G-2, G-3 and G-4 respectively.

  • The effect of three different grains supplemented diet as a dietary carbohydrate source on the growing rat, growth, food intake, FER and PER value, excretion of urinary arid fecal nitrogen and glucose and the level of glucose and cholesterol in serum blood was studied. Forty males and same number of females of Albino rats weighing male $58{\pm}2g$, female$62{\pm}2g$ were divided into eight experimental group, five male and female in each and fed rice diet, rice supplemented with wheat and rice supplemented with barley diet for 14 weeks. Under this condition wheat supplemented diet group shows the best FER, PER and body weight gain value. Especially in female group shows better FER, PER and body weight gain value compare to control diet group. Under the male groups wheat supplemented diet group shows lower FER, PER value and body weight compare to the control group but higher than those of barley diet group or rice alone. In female group the nitrogen retention shows also highest value by wheat supplemented diet group. By male group the wheat supplemented diet group shows not better value compare to the control group, but higer than barley supplemented group or rice alone. The nitrogen excretion through feces was significantly higher by grain supplemented diet group compare to grain the 20% sugar casein diet. The blood cholesterol content was slightly decreased by the control group which was fed disaccaride, compare to groups which were fed polysaccaride. But the free cholesterol to esterified cholesterol ratio shows lower value by control group than grain groups except the 70% rice supplemented with 30% barley group.

  • Edible insects have recently been increasingly promoted as a source of protein. As the number of farms rearing these insect increases, it is important to develop safe and nutritious feed sources to improve their commercial quality. The aim of the current study was to determine the effect of food by-products as feed supplements for the Korean rhinoceros beetle, Allomyrina dichotoma, which has been registered as a general food ingredient in Korea. We compared the effects of waste citrus peel, soybean curd cake, soybean oil meal, and brewers' dried grain on the growth of third instar larvae of A. dichotoma. Groups of larvae were fed with fermented sawdust and nine different combinations of the above by-products and the effects on their growth were measured until pupation. The highest survival rate was with feed supplemented with 10% brewers' dried grain (66.7%, p<0.05), and these larvae were also 26% heavier (p<0.05) than the control group that received no supplementation. In the 10% brewers' dried grain group, the larval period of third instar was shortened by almost 28 days (p<0.01) compared to the control group. Of all the groups, only that which was fed the brewers' dried grain supplement showed more than a 90% pupation rate (p<0.05). Therefore, brewers' dried grain may be useful as a source of feed for A. dichotoma.

  • The simulated die-casting process in which the traditional plaster casting process is combined with Rapid Prototyping technology is being used to produce Al, Mg, and Zn die-casting prototypes. Unlike in the die-casting process, molten metal in the conventional plaster casting process is fed via a gravity pour into a mold and the mold does not cool as quickly as a die-casting mold. The plaster castings have much larger and grosser grain structure as compared as the die-castings and the thin walls of the plaster mold cavity may not be completely fillet Because of lower mechanical properties induced by the large grain structure and incomplete Idling, the conventional plaster casting process is not suitable for the trial die-casting Process. In this work, an enhanced trial die-casting process has been developed in which molten metal in the plaster mold cavity is vibrated and pressurized simultaneously. Patterns for the casting are made by Rapid Prototyping technologies and then plaster molds, which have runner system, are made using these patterns. Imparted pressurized vibration to molten metal has made grain structure of castings much finer and improved fluidity of the molten metal enough to obtain complete filling at thin walls which can not be filled in the conventional plaster casting process.

  • A series of experiments were conducted to determine the effects of standard (ST), long-term (LT), and expander (EX) conditioners on nutritional value of phase-three nursery and finishing swine diets. In Exp. 1, 180 pigs (average initial BW of 11.7 kg) were fed com-soybean meal based diets (1.3% lysine) during a 28 d growth assay. Gain/feed was improved (p<0.004) with pelleting and pellet durability index (PDI) increased with degree of conditioning (LT>ST). However, there was no advantage for LT vs ST conditioning in rate or efficiency of gain (p>0.5). In Exp. 2, 180 pigs (average initial BW of 10.4 kg) were fed con-soybean meal based diets (0.9% lysine) during a 28 d growth assay, Pelleted diets tended to support greater ADG (p<0.08) and gain/feed (p<0.002) with no marked advantage from EX vs ST conditioning. In Exp 3, a total of 70 barrows (average initial BW of 54 kg) was used in a growth assay to determine the effects of feeding a com-soybean meal based diet processed with a standard (ST) steam conditioner, a long-term (LT) steam conditioner, and an expander (EX) conditioner. The conditioned diets were fed as mash (M) or pellets (P) to give a $2{\times}3$ factorial plus a meal control. PDI increased with degree of conditioning (EX>LT>ST). There was a trend (p<0.07) for greater ADG in pigs fed diets that had been thermally conditioned. Also, there was a general advantage in gain/feed with pelleting (p<0.04), but this advantage was pronounced only with standard conditioning. Indeed, the greatest gain/feed was observed for pigs fed the expander treatments (p<0.03) and the expander mash was used as efficiently as the expander pellets. There was no difference in backfat thickness among pigs fed the treatments (p>0.3). but the more extreme the processing technique. the greater the incidence and severity of stomach lesions (p<0.04). These results suggest maximum rate and efficiency of growth with pelleting after standard steam conditioning or simply feeding an expanded mash.

  • Four experiments with 2,020 nursery pigs (Triumph-4${\times}$PIC Camborough 22) were conducted at a commercial research site to evaluate the effects of including 30% distillers dried grain with solubles (DDGS) in late nursery diets on pig growth performance and to compare the effects of pelleted and meal diets containing 30% DDGS on growth performance and nutrient digestibility. In Exp. 1, 312 pigs (10.54${\pm}$0.16 kg) were allotted to two diets: corn-soybean meal based control diet and a corn-soybean meal diet containing 30% DDGS. In Exp. 2, 337 pigs (16.70${\pm}$0.14 kg) were used to validate Exp. 1 with similar diets. In Exp. 3, 665 pigs (11.77${\pm}$0.12 kg) were allotted to diets containing 30% DDGS, but in different forms: meal or pellet. Fecal samples were collected during the final day of the trials to measure nutrient and energy apparent total tract digestibility (ATTD). In Exp. 4, 706 pigs (18.40${\pm}$0.18 kg) were allotted to the same diets as Exp. 3. In Exp. 1 and 2, there was no (p>0.05) effect of DDGS on ADG, ADFI or G:F. In Exp. 3, pelleting improved (p<0.01) ADG (578 vs. 541 g/d) and G:F (714 vs. 674 g/kg), with no difference (p>0.05) in ADFI. The ATTD of most nutrients and energy were improved by pelleting (p<0.05). In Exp. 4, ADG (717 vs. 675 g/d) and G:F (680 vs. 648 g/kg) were improved by pelleting (p<0.01), with no difference (p>0.05) in ADFI. In conclusion, 10-23 kg pigs in late nursery phase can be fed up to 30% DDGS without having a detrimental effect on pig performance, and pelleting the diet will increase nutrient and energy availability.

  • Channel topography, sediment properties, channel landscapes and characteristics of land covers in Naeseongcheon and Wicheon River consisting of granites and sedimentary rocks, respectively, are compared and analyzed. Due to the differences of bedrocks, soils and characteristics of land covers in the basins, Wicheon River with the slow flow speed shows the larger variations in river stage than Naeseongcheon River. While Naeseongcheon River fed by the granite sediments throughout granular disintegration hs tthe regular grain size properties with coarse sand in the most of river, Wicheon River fed by sedimentary rocks indicates the dramatic decertses of grain size lower-ward. Naeseongcheon River with channel interferences such as sand-sized sediment transughoations, dredges, and aggregate collections is analyzed as poorer vegetation covers than Wicheon River due to the dramatic changes in channel surfaces.

  • The purpose of this study was to investigate the potential hypolipidemic effect of job's tears diet with the controlled intake of fiber in streptozotocin induced diabetic rats. Forty eight rats were fed either control diet or experimental diets (Raw, milled job's tears(RMJ); Raw, whole grain job's tears(RWJ);Steamed, milled job's tears(SMJ);Roasted, milled job's tears(OMJ)) for 3 weeks. The levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), free fatty acid(FFA) and triglyceride (TG) in plasma, liver and skeletal muscle were compared. Compared to diabetic control group, the level of plasma TC was lower in OMJ an SMJ fed rats, and was not different from that in RMJ and RWJ fed rats. The level of LDL-C was significantly lower in RMJ, OMJ and SMJ fed rats. For plasma HDL-C levels, no difference was observed among all group. Plasma FFA level significantly lower in RMJ, SMJ and RWJ fed rats, Plasma TG a levels of all job's ears fed groups were 50∼70% lower and liver TG levels of all job's tears fed groups were 70∼80% lower than those fo diabetic control group. For muscle TG, no differences were seen among all groups. These results suggest that steamed job's tears and roasted job's tears could have the potentaila on improving lipid profile fo diabetes in clinical setting and the different cooking methods of job's tears might affect the lipid profile of the diabetic rats.
