  • This experiment was carried out to determine growth characteristics, dry matter (DM) yield, seasonal yield distribution and nutritive value of early- and late maturity orchardgrass, 1990 to 1992. The cultivars used in this study were Potomac, Hallmark (early maturing cultivar) and Lidacta, Rancho (late maturing cultivar), and a mixture plot (Potomac 25% + Hallmark 25% + Lidacta 25% + Rancho 25%) was involved. The seeding rate was 20 kgha in all treatments. Plant height of Potomac and Hallmark was longer than that of Lidacta and Rancho. The dates of initial heading and 50% heading of early maturing cultivars (Apr. 30 and May 10) were 10 days earlier than those of late matuing cultivars. Potomac and Hallmark were upright, and Lidacta and Rancho were semi-upright type, and severe disease and weeds (30 ~ 40%) were observed at Lidacta plot. On an average of three years, the DM yields of Potomac (10,549 kglna), Hallmark (10,435 kg) and mixture (10,356 kg) were significantly (P<0.05) higher than those of Rancho (9,457 kg) and Lidacta (8,218 kg). However, seasonal yield distribution of late maturing cultivars was better than that of early maturing cultivars. The contents of crude protein, crude fat, crude fiber, nitrogen %ee extract, aude ash, neutral detergent fiber, P, K, Ca, and Mg were not significantly different between cultivars, but higher aude protein yield was found at Potomac, Hallmark and mixture plots. Based on the above results, it may be concluded that early maturing cultivars for high productivity, late maturing cultivars for seasonal yield distribution, and seeding of mixture andlor separation of early- and late maturing cultivars are recommended. Also Lidacta was a not promising cultivar due to low productivity, severe disease, and high weeds development.

  • This study was carried out to investigate the effects of fermented mushroom (Flammulina velutipes) by-products on meat quality characteristics in fattening Berkshire pigs. The fermented diet mainly contained 40.0% mushroom by-products, 26.0% rice bran, and 20.0% formula feed and was fermented for 5 d. The basal diet for the control (C) was substituted with 10% (T1), 30% (T2), 50% (T3), and 70% (T4) fermented diet. Warner-Bratzler shear forces (WBSF) were significantly lower (P < 0.05) in treatments than that in C. The meat color (lightness, redness, and yellowness) was significantly lower (P < 0.05) in treatments than that in C, whereas fat color (redness and yellowness) was significantly higher in treatments than that in C (P < 0.05). The compositions of palmitoleic acid and arachidonic acid were significantly higher (P < 0.05) in T4 than that in C. The amino acid composition of longissimus dorsi (LD) and the sensory evaluation of cooked meat were not affected by diet type. In conclusion, a diet of fermented mushroom by-products increased pH and backfat color, but decreased cooking loss, WBSF, and meat color of LD in growing-fattening Berkshire pigs.

  • This study suggests basic data on optimum thermal insulation for spring wear through an investigation of subjective thermal sensation, self-health image and actual wearing conditions. A survey of university students using a self-administered questionnaire was conducted to collect data on subjective thermal sensation, self-health image, wearing conditions, demographics and physical characteristics. The variable of wearing conditions was measured as the response to the clothing they were wearing. Garment items (26 types for males and 41 types for females) were suggested and the items worn by the students were converted into the thermal insulation values for clothing. The main results are as follows. As for the body type perception, males perceived themselves as not fat while females perceived themselves as not thin. As for the health perception, males perceived themselves healthier than females. As for the climate adaptability perception, females were more sensitive to cold than males. The average thermal insulation of clothing was 0.97clo (0.34-1.95clo) with higher insulation for males than females. Students were more sensitive to the cold when their BMI was lower, their body surface area per body weight was larger, and the more they perceived themselves as not healthy. There was a significant correlation between the self-health image of sensitiveness to cold and the thermal insulation of clothing. The results were synthetically discussed in terms of environmental physiology.

  • It is very interest to use transparent milk for various determination because milk emulsion or colloidal state bring out opacity. The fat globule can disperse by butanone and casein complex can also disintergrate to monomer by action of Triton with aide of SDS and NaOH in same milk phase at time because it can be possible that butanone have amphiphilic characteristic solvent also miscible. Our formulution of solvent can treat almost all type of milk products except with proportion of Triton/Butanone such as 8:2 and 9:1 . In spite of growth inhibition to contact with solvent it call be use also for microbial counting because this formulution did not attactk wall. This is why present technique can be applied to diver determination for the reason of milk payment system, quality control, and national planning or control of national dairy.

  • A total of 96 non-lean-type (Yorkshire $\times$ Landrace) $\times$ Duroc gilts and barrows weighing approximately 80 kg were randomly allocated to 24 pens under a 2 (sex) $\times$ 3 [diet; 3.4, 3.2, and 3.0 Mcal DE/kg {'high'-, 'medium'-, and 'low'-energy diets (HE, ME, and LE), respectively}] factorial arrangement of treatments. All animals were slaughtered approximately at 115 kg, after which carcass quality traits and grades and physicochemical and sensory characteristics of the loin related to meat quality were analyzed. The ADG and gain:feed were not affected by the sex or dietary treatment, whereas ADFI was greater in the ME vs HE group. Backfat thickness was greater in barrows vs gilts and also in ME and HE vs LE only in barrows. Enumerated carcass marbling and quality grade, which were highly correlated (r=0.56; P<0.01), were greater in barrows vs gilts. Physicochemical characteristics including the color, pH, drip loss and contents of moisture, protein, and fat of fresh loin, as well as sensory characteristics of fresh and cooked loin, were not affected by the sex or dietary treatment, except for shear force for cooked loin which was greater (P<0.05) in LE and ME vs HE. In conclusion, it is thought that ME is comparable to HE in terms of the effect on growth and carcass quality of finishing pigs, but that the relative effect of LE vs ME needs to be further studied.

  • Tempeh-type fermented products were prepared from soybean, sorghum or mixture of soybean and sorghum(1 : 1) with the traditional Indonesian inoculum(LARU : mixed cultures of Rhizopus oligosporus). Fermentation increased protein and fiber contents in the soybean tempeh(ST) and tempeh of soybean-sorghum mixture(SSM). Fat content was slightly higher in sorghum tempeh(SGT) and SSM than that of control. During the fermentation, pH, soluble solid and soluble nitrogen were increased, while no significant change was found in the total solids. The trypsin inhibitor activity(TIA) and phytic acid content decreased after 32 hrs fermentation. It is suggested that Rhizopus oligosporus is capable of hydrolyzing trypsin inhibitor and phytic acid of the substrate. Thiamine and niacin contents increased in all samples as compared with the unfermented control. In amino acid level, there were some decreased in total amino acids after 32 hrs fermentation in three types of tempeh. While the concentrations of lysine, valine. tyrosine and alanine in ST, SGT and SSM were increased those of serine and glutamic acid were decreased in compare to the unfermented control.

  • Squamous cell carcinoma is the most common type of oral cancer and odontogenic myxoma is relatively uncommon benign tumor of mesenchymal origin. There are, to our knowledge, no prior reports of simultaneously occurring squamous cell carcinoma and odontogenic myxoma of the jaw bones. In this case, at first, the plain films and computed tomograms revealed a large expansile multilocular radiolucent lesion on left mandible and marked expansion of cortical plate. In addition this radiograms revealed also infiltrative bony destruction of anterior and medial border of ascending ramus of left mandible and alveolar bone of left maxilla, floating teeth on left lower molar area and metastatic enlargement of left submandibular, jugular digastric and spinal accessory lymphnodes. Magnetic resonance imaging of this patient revealed infiltrative growth of tumor on alveolar bone of left maxilla, left retromolar fat pad. left masseter and left medial pterygoid muscle. Intraoral presurgical biopsy presented typical features of squamous cell carcinoma. After chemotherapy with radiation therapy during 6 months. this central lesion was diagnosed as odontogenic myxoma by the postsurgical biopsy. After 3 months, this patient presented multiple metastatic signs at lumbar spines, rib and liver. Consequently, our case is simultaneous occurrence of squamous cell carcinoma and odontogenic myxoma.

  • Objective: This study examined the influence of dietary supplementation of Nigella sativa seeds, Rosmarinus officinalis leaves and their combination on carcass attributes, fatty acid (FA) composition, gene expression, lipid oxidation and physicochemical properties of longissimus dorsi (LD), semitendinosus (ST), and supraspinatus (SS) muscles in Dorper lambs. Methods: Twenty-four Dorper lambs ($18.68{\pm}0.6kg$, 4 to 5 months old) were randomly assigned to a concentrate mixture containing either, no supplement (control, T1), 1% Rosmarinus officinalis leaves (T2), 1% Nigella sativa seeds (T3), or 1% Rosmarinus officinalis leaves+1% Nigella sativa seeds (T4) on a dry matter basis. The lambs were fed the treatments with urea-treated rice straw for 90 days, slaughtered and the muscles were subjected to a 7 d postmortem chill storage. Results: The T2 lambs had greater (p<0.05) slaughter and cold carcass weights than the control lambs. Dietary supplements did not affect (p>0.05) chill loss, dressing percentage, carcass composition, intramuscular fat and muscle pH in Dorper lambs. Meat from supplemented lambs had lower (p<0.05) cooking and drip losses, shear force, lightness, and lipid oxidation and greater (p<0.05) redness compared with the control meat. The impact of dietary supplements on muscle FA varied with muscle type. Diet had no effect (p>0.05) on the expression of stearoyl-CoA desaturase and lipoprotein lipase genes in LD and ST muscles in Dorper lambs. The T2 and T3 diets up regulated the expression of AMP-activated protein kinase alpha 2 gene in LD and ST muscles and up regulated the expression of sterol regulatory element-binding protein 1 in ST muscle in Dorper lambs. Conclusion: Dietary supplementation of Nigella sativa seeds and Rosmarinus officinalis leaves had beneficial effects on meat quality in Dorper lambs.

  • Botryosphaeran, a water-soluble exopolysaccharide of the ${\beta}-(1{\rightarrow}3;1{\rightarrow}6)$-D-glucan type that has been isolated from the culture medium of Botryosphaeria rhodina MAMB-05 grown in submerged fermentation using glucose as the sole carbon source, was previously demonstrated to be non-genotoxic in peripheral blood and bone marrow, and exhibited strong anticlastogenic activity. In the present study, the effects of botryosphaeran were investigated in streptozotocin-induced diabetic rats as well as in high-fat diet-fed hyperlipidemic Wistar rats. The plasma glucose level was reduced by 52% in the diabetic group of rats after administration of 12 mg botryosphaeran/kg body weight of the rats (b.w.)/day by gavage over 15 days. A reduction in the median ration intake was accompanied by an increase in the median body weight gain, as well as the efficiency of food conversion. These results demonstrate that botryosphaeran has protective effects by reducing the symptoms of cachexia in Diabetes mellitus. Botryosphaeran administered by gavage at a concentration of 12 mg botryosphaeran/kg b.w./day over 15 days also reduced the plasma levels of total cholesterol and low density lipoprotein-cholesterol by 18% and 27%, respectively, in hyperlipidemic rats. Based on these findings, we conclude that botryosphaeran possesses hypoglycemic and hypocholesterolemic properties in conditions of diabetes mellitus and hyperlipidemia, respectively, and may be used as an oral anti-diabetic agent.

  • The beef forequarter muscle comprises approximately 52% of carcass weight. The objective of this study was to evaluate the physiochemical characteristics and meat color from forequarter muscle of Holstein steers. Fifteen forequarter muscles were trimmed of external connective tissue and fat. An experimental group of eight Holstein steers was assessed using meat color, water-holding capacity, drip loss, and Warner-Bratzler shear force value at the same quality grade. The M. omotransversarius (0.45 kg) had the highest (p<0.05) lightness (L*) value, whereas the M. teres major (0.4 kg) and M. triceps brachii (caput laterale) (0.52 kg) had the lowest (p<0.05) values. The M. semispanitus capitus (1.48 kg), which is a neck muscle, had the highest values for both redness (a*) and yellowness (b*), whereas the lowest (p<0.05) values were for the M. teres major. The M. omotransversarius, M. latissimus dorsi (1.68 kg), and M. rhomboideus (1.2 kg) were ranked high (p<0.05) in water-holding capacity. The drip loss value was the highest for the M. longissimus dorsi thoracis (p<0.05; 1.86 kg), while the M. infraspinatus (2.28 kg), M. supraspinatus (1.38 kg), M. brachiocephalicus (1.01 kg), and M. pectoralis superficialis (1.18 kg) had the lowest (p<0.05). The Warner-Bratzler shear force value indicated that the M. pectoralis profundus (3.39 kg), M. omotransversarius, and M. brachiocephalicus were the toughest (p<0.05), whereas the M. subscapularis (0.86 kg), M. longissimus dorsi thoracis, M. teres major, and M. infraspinatus were the most tender cuts (p<0.05). Here, muscle type explained most of the variability in the forequarter physiochemical characteristics. Thus, our findings suggest that these muscle profile data will allow for more informed decisions when selecting individual muscles to produce value-added products from Holstein steers.
