  • The objective of this study was to evaluate the effects of ruminally-protected methionine supplementation (0, 7, or 14 g/head/d) on nutrient intake, digestibility, growth performance, carcass, and meat characteristics of Awassi ram lambs fed finishing diets. Twenty four Awassi ram lambs ($16.8{\pm}1.17kg$ body weight) were randomly assigned to 3 treatment diets (8 lambs/treatment) and housed in individual pens. Lambs were given an adaptation period of 7 days before the intensive feeding period that lasted for 86 days. On day 74 of the trial, a digestibility experiment was performed. At the end of the trial (d 86), all lambs were slaughtered to evaluate carcass characteristics and meat quality. Increasing the level of methionine supplementation did not improve (p>0.05) performance nor feed conversion ratio. Nutrient intake and digestibilities were not influenced (p>0.05) by methionine supplementation. There were no differences in final weight, hot and cold carcass weights, dressing percentages or any of the measured non-carcass components. Tissues and fat depth measurements together with all meat quality attributes measured on longissimus muscle of the loin cut were not affected by methionine supplementation. The only meat quality parameters affected were redness (a*) and the hue angle being higher for the control group (p<0.05). These results suggest that methionine supplementation is not likely to produce any production benefits in nutrient digestibilities, performance or carcass characteristics of ram lambs fed a high performance diet.

  • The purpose of this study is to systematize various clothing production methods that domestic fashion brands are utilizing to produce fashion products, and to propose effective clothing production methods according to the characteristics. The research methods are contents analysis method of the literatures, articles, reports, and interviewing method of the practitioners who are in charge of the production of fashion. First, the clothing production methods of the domestic fashion brands are categorized as follows. It is divided into a fashion brand management method and a promotion company entrustment method based on who carries out the clothing production and management. The fashion brand management method is subdivided into the 'rental-production', 'CMT', and 'self-production' methods. All three methods are performed at domestic and global sourcing, but the CMT method is more utilized at the global sourcing. The promotion company entrustment method is subdivided into the 'full consignment production method', the 'CMT method involving promotion company', and 'direct buying method by promotion company'. All methods are performed at domestic and global sourcing. Second, the results of reviewing effective clothing production methods, according to characteristics are as follows. If fashion brands control the production and management, they use all three fashion brand management methods. The fashion brands use the promotion company entrustment method when they wants to offer special products, or the number of items is large, or the production management is difficult, or the manpower and equipment size is reduced. The domestic sourcing is utilized by fashion brands and promotion companies when production management is required for high quality apparel production, in case of trendy and complex designs, spot production, and in small quantity production. The global sourcing is utilized by fashion brands and promotion companies when it comes to lowering the production cost, fashion brands preferred the mass production of apparel with design that can be pre-planned.

  • Computer-assisted animation production tools have an important role in animation production industries. They could reduce the production cost and time, but they rarely copy artistic characteristics of an animators. In this paper, a new computer-assisted line pattern drawing system is proposed. The system automatically copies artistic characteristics of an animator and applies them to computer-generated animations. The artistic characteristics are captured from key frames drawn by an animator. The result shows that the presented approach can copy artistic characteristics from key frames well and reduce time and cost for producing artistic animations.

  • This study was carried out to obtain the several data for improving the seed supply in Pinus densiflora. Seed characteristics and germination properties according to change of cone production from 2003 to 2006 were analyzed in three plus stands of P. densiflora. P. densiflora showed good production at interval of two years in the periodicity of seed production. Seed potential and percent of filled seed (PFS) among the major seed characteristics showed positive relations to the change of cone production, whereas percent of developed seed (PDS) and seed efficiency showed opposite trend. As a result of regression analysis between seed characteristics and cone production, seed potential ($R^2=0.682$, p<0.01) and PFS ($R^2=0.161$, non-significant) presented positive correlation with cone production while PDS ($R^2=0.418$, p$R^2=0.308$, non-significant) presented negative correlation. In germination properties percent of germination (PG) showed similar tendency to cone production, while mean germination time (MGT) showed opposite tendency. As a result of regression analysis between germination characteristics and cone production, PG showed positive correlation, whereas MGT showed negative correlation. Therefore, we could expect high germination percentage and short period for germination when we harvested cones at good cone production time.

  • A study was conducted to examine the influence of maize (Zea mays) and cowpea (Vigna unguniculata) intercropping on fodder biomass production and silage characteristics. Maize fodder was cultivated alone and intercropped with cowpea at seed ratio of 85:15 and 70:30. Fodder was harvested at heading stage (at about 35% dry matter). The data indicated significant increase in biomass and crude protein production of maize intercropped with cowpea at seed ratio 70:30 followed by seed ratio 85:15 as compared to maize alone. However, no (p>0.05) difference was observed in TDN production among the three treatments. Four types of silages from, I) maize alone, II) maize and cowpea (85:15), III) maize and cowpea (70:30) and IV) maize supplemented with 2.5% urea were prepared. After 60 days of ensiling period, silage samples were analysed for proximate composition and fermentation characteristics. Crude protein and lactic acid values of silages I, II, III and IV were 8.52, 9.82, 14.90 and 13.96% and 9.00, 9.38, 10.86 and 7.43%; respectively. In situ dry matter digestibility was maximum in silage III followed by silages II, IV and I. The results suggested that intercropping of maize and cowpea at seed ratio 70:30 increased fodder production and produced quality silage.

  • Ruminal methane production functions as the main sink for metabolic hydrogen generated through rumen fermentation and is recognized as a considerable source of greenhouse gas emissions. Methane production is a complex trait affected by dry matter intake, feed composition, rumen microbiota and their fermentation, lactation stage, host genetics, and environmental factors. Various mitigation approaches have been proposed. Because individual ruminants exhibit different methane conversion efficiencies, the microbial characteristics of low-methane-emitting animals can be essential for successful rumen manipulation and environment-friendly methane mitigation. Several bacterial species, including Sharpea, uncharacterized Succinivibrionaceae, and certain Prevotella phylotypes have been listed as key players in low-methane-emitting sheep and cows. The functional characteristics of the unclassified bacteria remain unclear, as they are yet to be cultured. Here, we review ruminal methane production and mitigation strategies, focusing on rumen fermentation and the functional role of rumen microbiota, and describe the phylogenetic and physiological characteristics of a novel Prevotella species recently isolated from low methane-emitting and high propionate-producing cows. This review may help to provide a better understanding of the ruminal digestion process and rumen function to identify holistic and environmentally friendly methane mitigation approaches for sustainable ruminant production.

  • In order to provide recommendations on the most useful forage species to smallholder farmers, eleven grass and eleven legume forages grown in Abomey-Calavi in Republic of Benin were investigated for nutritive value (i.e. chemical composition and energy content) and fermentation characteristics (i.e. gas and volatile fatty acid production, organic matter degradability). The in vitro gas production technique was used, incubating the forages for 120 h under anaerobic condition with buffalo rumen fluid. Compared to legume, tropical grass forages showed lower energy (8.07 vs 10.57 MJ/kg dry matter [DM]) and crude protein level (16.10% vs 19.91% DM) and higher cell wall content (neutral detergent fiber: 63.8% vs 40.45% DM), respectively. In grass forages, the chemical composition showed a quite high crude protein content; the in vitro degradability was slightly lower than the range of tropical pasture. The woody legumes were richer in protein and energy and lower in structural carbohydrates than herbaceous plants, however, their in vitro results are influenced by the presence of complex compounds (i.e. tannins). Significant correlations were found between chemical composition and in vitro fermentation characteristics. The in vitro gas production method appears to be a suitable technique for the evaluation of the nutritive value of forages in developing countries.
