The present study aimed to assess the effect of dietary substitution of soybean meal (SBM) with dehulled-micronized faba bean (Vicia faba var. minor) in guinea fowl broilers on their growth traits, carcass quality, and meat fatty acids composition. In this trial, 120 day-old guinea fowl keets were randomly assigned to two treatments which were fed from hatch to 12 weeks of age. Birds were fed two wheat middlings-based diets comprising of a control treatment which contained SBM (78.3 g/kg) and a test diet containing dehulled-micronized faba bean (130 g/kg) as the main protein source. Substituting SBM with faba bean had no adverse effect on growth traits, dressing percentage, or breast and thigh muscles relative weight of the guinea fowls. Conversely, a decrease (p<0.05) of abdominal fat was found in guinea fowls fed the faba bean-diet. Breast muscle of birds fed faba bean had higher $L^*$ score (p<0.05) and water-holding capacity (p<0.05) than the SBM control diet. Meat from guinea fowls fed faba bean had less total lipids (p<0.05) and cholesterol (p<0.01), and higher concentrations of phospholipids (p<0.01). Feeding faba bean increased polyunsaturated fatty acid concentrations in breast meat and decreased the saturated fatty acid levels. Moreover, dietary faba bean improved the atherogenic and thrombogenic indexes in guinea fowl breast meat. Results indicated that substitution of SBM with faba bean meal in guinea fowl diet can improve carcass qualitative traits, enhancing also meat lipid profile without negatively affecting growth performance.

Two experiments were conducted to investigate the effect of feeding a diet supplemented with swine hair protein (SHP) on the nutrient digestibility of Korean native chickens and their egg production as well as on egg quality. In experiment 1, twenty roosters of the Hanhyup-3 strain were assigned to an individual cage to give 10 replicates per treatment (i.e., 0 and 10% of SHP), and the nutrient digestibility in response to the SHP supplementation was measured. In experiment 2, fifty-four layers of the Hy-Line strain were assigned to an individual cage to give 27 replicates per treatment (i.e., 0 and 10% of SHP), and egg production and egg quality were measured. In experiment 1, no significant difference (p > 0.05) was found in the digestibility of crude protein, crude fat, nitrogen-free extract (NFE), and crude fiber in response to the diet supplemented with SHP. In experiment 2, although no significant difference (p > 0.05) was found with the dietary treatments, the 10% SHP supplemented diet decreased (p < 0.05) the feed intake of laying hens. However, the SHP supplemented diet did not affect (p > 0.05) the laying rate, egg weight and feed conversion ratio of those fed the diet. Eggshell thickness and yolk color decreased (p < 0.05); however, eggshell strength, eggshell color, albumen height and Haugh units increased (p < 0.05) by feeding layers a diet supplemented with SHP. In conclusion, the results suggest that 10% SHP supplemented in a poultry diet could be a useful protein source.

This study planned to compare the effects of source and amount of dietary n-3 fatty acid, tuna oil and perilla oil, on lipid metabolism and eicosanoids production in Spargue-Dawley strain male rats. Weaning rats were fed 5 different experimantal diets for 4 weeks. (S : beef tallow 50%+sesame oil 50%, T1 : beef tallow 50%+sesame oil 40%+tuna oil 10%, T2 : beef tallow 50%+sesame oil 25%+tuna oil 25%, P1 : beef tallow 50%+sesame oil 40%+perilla oil 10%, P2 : beef tallow 50%+sesame oil 25%+perilla oil 25%) Food intake was higher in T2 group than in other groups, but body weight gain and food efficiency tate were not different among groups. Plasma total lipid and triglyceride were significantly lower in groups fed perilla oil as much as groups fed tuna oil than in S. But tuna oil reduced plasma cholesterol level more than perilla oil. Liver total lipid per unit, cholesterol and triglyceride were not affected by dietary fat sources. Peroxisomal $\beta$-oxidation was higher in T1 and T2 than in P1 and P2. Activities of glucose 6 phosphate dehydrogenase and malic enzyme were lower in T1 and T2 than in group fed sesame oil only. Plasma TXB2 was affected by n-3 fatty acid consumption, and it was lower in perilla oil groups as much as tuna oil groups than in S. But 6-keto PGF1$\alpha$ was not different among experimental groups. The results of this study indicated that tuna oil and perilla oil both decreased plasma lipids, however, the mechanism may be different. And tuna oil and perilla oil had a similar effects on eicosanoids production.

This study was conducted to determine the nutritional characteristics of horsemeat and bone meal in comparison with those of beef and pork presented by Dietary Reference Intakes For Koreans. Longissimus muscle and large metacarpal bone samples were collected from 20 fattened Jeju horses. Muscle samples were subjected to proximate analysis, assays for fatty acid profile and minerals, and bone samples to mineral assays. Horsemeal had similar levels of protein (21.1 vs 21.0 or 21.1%) and lower levels of fat (6.0 vs 14.1 or 16.1%) compared with beef or pork, respectively. Horsemeat had much higher levels of palmitoleic (8.2 vs 4.4 or 3.3%) and $\alpha-linolenic$ (1.4 vs 0.1 or 0.6%) acids than beef or pork, respectively. Linoleic acid was much higher in horsemeat (11.1%) and pork (10.1%) than in beef (1.6%). PUFA:SFA and n-6:n-3 ratios in horsemeat were 0.29 and 10.2, respectively. There were no big differences in mineral contents between horsemeat, beef and pork. For daily recommended mineral intakes of male adults (Dietary Reference Intakes For Koreans), phosphorus, sodium, potassium, iron, zinc and copper can be provided up to 24, 2.5, 6.7, 21, 26 and 40%, respectively, by 100 g raw horsemeat, but calcium and manganese levels are negligible. Horse cannon bone had much higher mineral contents especially in calcium (10,193 mg/100 g), phosphorus (5,874 mg/100 g) and copper (0.79 mg/100 g). Thiamin, riboflavin, niacin and retinol contents were 0.20, 0.21, 1.65 mg/100 g and $30{\mu}g/100g$, respectively. But ascorbic acid and beta-carotene were not detected. Our data demonstrated that higher levels of palmitoleic and $\alpha-linolenic$ acid in horsemeat than in beef and pork may be beneficial for human health. Horsemeat and bone meal are a good source of some minerals and vitamins.

Contributions of specific foods to absolute intake and between-person variance in 13 nutrients were examined to develop a short food frequency questionnaire (FFQ) for the Korean elderly using dietary data collected by a semiquantitative FFQ with 96 food items. The contributions of specific foods to 90% absolute nutrient intake were measured by assessing their percentage to the total consumption of a nutrient by our samples(n=98). To assess the contribution of the foods to the between-person variance in intake of each specific nutrient, stepwise multiple regression was performed. Cumulative R2 served as the measure of contribution to variation in intake. The most important food source of absolute intake was rice for energy and protein. Important foods of between person variance contribution include bread for energy and pork for protein. Important foods of absolute and variance contribution of nutrient intake were similar for fat(noodles including jajangmyun and kalguksu), calcium(anchovy and milk) and vitamin A (carrot). The number of foods necessary to account for the variation in nutrient intake among older people in Korea differ considerably by nutrient: 18 - 43 and 8-26 foods were accounted for the respective 90 and 80% of absolute intake depending on nutrients. Carbohydrates and vitamin A and C had relatively a few major sources, thus may be assessed well by a small number of foods. Conversely, iron, potassium and B vitamins appear to need longer lists of foods. Fewer numbeer (6 - 12 and 4 - 9) of foods were required for the corresponding percentages of between-person variation for all nutrients. Depending on nutrients, 0.980-0.995 and 0.924-0.987 were respective correlation coefficients of nutrient intakes measured by 96 food items with those by lists of foods for 90% and 80% of absolute intake contribution. These findings suggest that an incomplete food list on the basis of its contribution to absolute and between person variation intakes may still be effective in discriminating among individuals. The results of this study may be useful in the design and use of dietary questionnaire.

This study was designed to investigate the possible utilization of mugwort as a source of functional ingredients. The approximate composition for mugwort powder was 5.06% moisture, 1.98% crude protein, 4.65% crude fat, 5.85% ash and 82.46% carbohydrate. The highest mineral content was potassium. The contents of total phenolic compounds and condensed tannin were 114 mg% and 11,000 mg%, respectively. The highest electron donating ability(EDA) was observed from the ethyl acetate and butanol fractions of mugwort powder but the lowest was shown by the hexane fraction. In color values, with increasing mugwort powder content, the 'lightness', 'redness' and 'yellowness' decreased in the crust, while in the crumb bread the 'lightness' decreased and the 'redness', and 'yellowness' increased. With the addition of mugwort powder as a substitute for strong flour over the range from 2.5% to 10.0%, the ratio of the volume and specific volume of white bread decreased while its weight increased. In the texture measurements for white breads, the hardness decreased slightly with the addition of 2.5% mugwort powder, but then increased with further additions of mugwort up to 10.0%. The addition of 2.5% mugwort powder increased the springiness and gumminess of white bread. The highest sensory scores for color, flavor, taste, texture and overall acceptance as evaluated by a student sensory panel were obtained from white bread with 2.5% mugwort powder and from the control. The highest sensory scores as evaluated by a baker sensory panel were obtained from white bread with 2.5% mugwort powder. In ranking test, overall acceptability of white bread was the highest in the control. Overall acceptance scores by sensory evaluation of white bread with 2.5% mugwort powder were not significantly different from those of control.

Fifty four crossbred gilts of 26.38${\pm}$0.85 kg body weight and 25 weeks of age were randomly divided into three groups, having six replicates of three animals each and were assigned to one of the three dietary treatments containing corn, wheat bran and rice bran (RB) at 35, 47 and 0% in $R_1$; 17.5, 23.5 and 41% in $R_2$ and 0, 0 and 82% in $R_3$. Soybean meal and fishmeal were used as source of protein at 10 and 6%, respectively, in all the rations. Average daily CP, DCP, DE and ME intake per kg $W^{0.75}$ and body weight gains were lowest (p<0.01) in gilts fed 82% RB ($R_3$), followed by $R_2$ and R1. Utilization of protein with respect to nitrogen balance and DCP conversion efficiency did not differ (p>0.05) between the treatment groups. All the gilts were in positive nitrogen balance. However, the excretion of dietary nitrogen and energy through faeces was higher (p<0.01) in gilts fed RB. However, the DE and ME conversion efficiency were higher (p<0.01) in gilts fed RB. Therefore, it can be concluded that the digestibility of energy and protein in diets containing rice bran goes on decreasing with the increasing level of fat and fibre, but the metabolizability of the energy and protein was better in pigs fed RB in the diet.

This study determined the level of fermented soybean meal (FSM) that could be substituted for fish meal in the diet for parrot fish Oplegnathus fasciatus. Fish meal (FM) was used the sole protein source in the control diet. FSM was substituted for 20, 40, 60, 80, and 100% of the fish meal in the experimental diets. The FSM resulted in increased crude protein, crude fat, and crude ash, but decreased crude fiber. The methionine and tryptophan contents in the FSM increased, while lysine and threonine decreased. The 18:2n-6 fatty acid content decreased from 55.30% to 28.67%. Fermentation increased 20:5n-3 (EPA) and 22:6n-3 (DHA) by 2.03% and 15.54%, respectively, although the differences were not significant. Based on growth performance, we concluded that FSM could replace up to 60% of FM for the maximum growth of juvenile parrot fish.

Four Holstein$\times$Indigenous cows with ruminal canulas were used in a 4$\times$4 Latin square design with 28 d periods to determine the effect of replacing nonforage fiber source (NFFS) from cassava residues for non-fiber carbohydrates (NFC) on ruminal fermentation characteristics and milk production. Dietary treatments contained 17% forage neutral detergent fiber (FNDF) from corn silage and 0, 3, 6 and 9% nonforage NDF from cassava residues and 11% nonforage NDF from other NFFS, so that levels of nonforage NDF were 11, 14, 17 and 20% dry matter (DM). Intakes of DM and net energy for lactation, average daily gain and milk fat percentage were not different (p>0.05). Ruminal pH, ammonia concentrations, acetate to propionate ratios, 24 h in sacco fiber digestibility significantly increased with increasing contents of nonforage NDF from cassava residues. Concentrations of VFA, urinary excretion of purine derivatives, milk protein percentage, production of milk and 4% FCM significantly decreased. These results suggest that NFC in diets is one of the limiting factors affecting productivity of dairy cows in the tropics and thus NFFS is better used as partial replacements for FNDF.
