Effect of Non Forage High Fibrous Feedstuffs as Fiber Sources in Total Mixed Ration on Gas Production Characteristics and in vitro Fermentation
Songsak Chumpawadee,Opart Pimpa
Pakistan Journal of Nutrition , 2008,
Abstract: The objective of this study was to determine the effect of non forage high fibrous feedstuffs as fiber sources in a total mixed ration on gas production characteristics and in vitro fermentation using an in vitro gas production technique. The experiment was designed in CRD with five replicates per treatment. The fiber sources in the total mixed ration were rice straw (rt-TMR), tomato pomace (tp-TMR), palm meal (pm-TMR), dried brewer gain (db-TMR) and soybean hulls (sh-TMR). The results showed that kinetic gas production, in vitro dry matter digestibility and in vitro organic matter digestibility, were significantly different among treatments (p<0.05). The soybean hulls as a fiber source in the total mixed ration gave the highest IVDMD, IVOMD and gas production parameter. In vitro fermentation end-products consisting of NH3-N, TVFA and pH were significantly different among the treatments (p<0.05); however, the pH values were relatively stable at 7.01-7.16. All treatment means were within the normal range. NH3-N concentration was in the optimal range for rumen ecology microbial activity. Future research should investigate the impact of the ability of non forage high fibrous feed to replace forage in intact animal.

Abstract: Three male yearling swamp buffaloes and three Kedah Kelantan (KK) zebu cattle of similar age and sex were used. Animals were each fed 4 kg of a total mixed ration diet (TMR) consisting of 40% oil palm frond and 60% concentrate for 2 wk. Cr2O3 was used as the indigestibility marker. On day 15, animals were sacrificed and the digesta in the small intestine was collected to study the absorption of purines in the segments, each being 60 cm in length of the small intestine. Deoxyribonucleic acid (DNA) disappearance from the first to the 15th segment did not differ between buffaloes and cattle (P > 0.05), averaging 94% and 91%, respectively. Ribonucleic acid (RNA) disappearance for buffaloes was lower than that for cattle (P < 0.05) (82% and 95%, respectively) but did not differ between species (P > 0.05). Similarly, purine absorption did not differ between buffaloes and cattle (P > 0.05). Total purine absorbed within 20 segments was 81% and 92% respectively for buffaloes and cattle. Although disappearance of RNA, DNA and the purine bases (PB) in the small intestine did not differ between cattle and swamp buffaloes (P > 0.05), based on concentration per Cr marker, the quantity of unabsorbed PB in the last 5 segments of the small intestine of buffaloes was higher than that of cattle (P < 0.05). Although this suggests that absorption of PB in the small intestine of buffaloes was lower than of cattle, it can not explain the large differences in the PD urinary excretion rates between the species.

Abstract: This paper examines online engagement in the business learning context among international and local students in Australia. Online engagement among business students and lecturers has long been criticized as the key problems in adopting online materials and methods in business education. In examining factors affecting online engagement in business education, the data was collected from UNDERGRADUATE students in finance, accounting and international business undergraduate students. Moreover, learning and teaching techniques that enhance the quality of online engagement were also investigated in this study. Key factors include the nature of the course, technical aspects from the institutions and cultural BACKGROUNDS from the students. This study also finds roles of key stakeholders in business education such as lecturers, technicians and policy makers CONTRIBUTING to the level of online engagement among business students.

Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.24046
Abstract: The concept of creativity in education is linked with a range of social factors. By examining the relationship among social, educational factors and creativity among students in Thailand, this study proposes that educators and policy makers must understand various global factors that affect contemporary education. They include changes in contemporary politics, culture and communication in the global education contexts. The study confirms that modern cultural factors and concept of gender are marked as key predictors of the development of creativity among young Thai students. It is reported in this study that various facets of globalization also promote creativity and imagination among young Thais. Young Thai students in this study are, in fact, willing to participate in many creative educational and social activities.

Amazing Thailand: Organizational Culture in the Thai Public Sector
Nattavud Pimpa
International Business Research , 2012, DOI: 10.5539/ibr.v5n11p35
Abstract: Thai culture is unique and renowned for its complexities. To understand the repercussion of culture on Thai management style in the public sector context, this study investigates the key ‘characteristics’ and ‘nature’ of culture in the Thai public sector organizations. By adopting Hofstede’s theory of cultural dimensions, this study proposes that the new generation in the Thai organizations acts differently from the cultural stereotype from the literature in Thai culture and management. The results show that younger generations in the Thai public sector may be more individualistic, familiar with the concept of organizational change and appreciate the Western management concepts. This study, however, also confirms that avoiding conflict and uncertainties remain a key characteristic in the Thai public sector system.

Journal of Animal and Veterinary Advances , 2012,
Abstract: The objective of this study, was to determine the effect of fodder tree as fiber sources in a total mixed ration on feed intake, nutrient digestibility, chewing behavior and ruminal fermentation. Four Brahman-Thai native crossbred steers with an average initial body weight of 233.3+13.09 kg were randomly assigned in a 4x4 Latin Square Design. During each of four 21 days periods, the animals were fed 4 Total Mixed Rations that varied in the fiber sources: Corn cob as fiber sources (C-TMR, control), Burma padauk leave as fiber source (B-TMR), Rain tree leave as fiber source (R-TMR) and Siamese rough bush leave as fiber source (S-TMR). The results showed that feed intake, crude protein digestibility, chewing time and ruminal fermentation were significantly different among treatments (p<0.05). Dry matter intake of animal fed R-TMR, B-TMR had higher than S-TMR and C-TMR (control). In this study, R-TMR had lowest crude protein digestibility. The number of chewing had highest when animals fed B-TMR. At 2 h post feeding C-TMR had the highest NH3-N, when compared with other TMRs. The fodder tree as a fiber source in the total mixed ration has positive effect on feed intake and chewing behavior. Therefore, fodder trees can be use as fiber sources in TMR, especially when acute shortage of conventional fiber sources.
Effects of Non Forage Fiber Sources in Total Mixed Ration on Feed Intake, Nutrient Digestibility, Chewing Behavior and Ruminal Fermentation in Beef Cattle

Journal of Animal and Veterinary Advances , 2012,
Abstract: The objective of this study was to determine the effect of non forage fiber sources in a total mixed ration on feed intake, nutrient digestibility, chewing behavior and ruminal fermentation. Five Brahman-Thai native crossbred steers with an average initial body weight of 188±16.56 kg were randomly assigned in a 5x5 Latin square design. During each of five 21 days periods, the animals were fed 5 total mixed rations that varied in the non forage fiber sources, rice straw as fiber sources (rt-TMR, control), tomato pomace as fiber source (tp-TMR), palm meal as fiber source (pm-TMR), dried brewer gain as fiber source (db-TMR), soybean hulls as fiber source (sh-TMR). The results showed that feed intake, crude protein digestibility, chewing time, total number of chew and ruminal fermentation were significantly different among treatments (p<0.05). The palm meal as a fiber source in the total mixed ration has negative effect on feed intake and chewing behavior, although enhanced by 5% of long hey fiber. However, tomato pomace, dried brewer gain and soybean hulls can be used as fiber sources in TMRs, when enhanced with 5% of long hey fiber.

Songklanakarin Journal of Science and Technology , 2010,
Abstract: Bismuth ruthenate pyrochlores, potential cathode materials for intermediate temperature solid oxide fuel cells(ITSOFCs), were prepared via solid-state and sol-gel method. Effects of the preparation routes and conditions on the phase and microstructures of the materials were investigated in this study using XRD and SEM. The study showed that the preparation method and the adding sequence of the starting meterials have a significant effect on the crystal phase and the particle size obtained. Sol-gel synthesis could yield a material with only pyrochlore structure, i.e. Bi2Ru2O7, while the solid state method yielded powder with a small amount of the secondary RuO2 phase. The sol-gel synthesis resulted in materialswith a finer particle size (~0.3-1.0 μm) compared to powder synthesized via the solid state reaction method.
LEADERSHIP STYLES: A STUDY OF AUSTRALIAN AND THAI PUBLIC SECTORS
Nattavud Pimpa,Timothy Moore
Asian Academy of Management Journal , 2012,
Abstract: Leadership is deeply attached to culture. This study compares leadership styles in Thai and Australian public sectors. The data were collected from staff in public sector settings in Australia and Thailand. The results confirm four leadership styles that suit the public sector culture in both countries: communication-oriented, strategic thinking and planning, relationship building, and conflict management. In the Thai public sector system, leadership that focuses on goal orientation is ranked most highly: Australian public sector organisations focus on leadership that fosters equity among organisational members, creates a supportive environment in the workplace, and facilitates participation. It is evident from this study that significant distinctions between the organisational cultures of Thailand and Australia are matched by marked dissimilarities of preferred leadership styles. Thus, an understanding of local organisational culture is important for effective leadership at all levels.
