In vitro ruminal fermentation and fatty acid production by various oil seeds

Rumen simulating techniques (Rusitec) were used to determine the impact of diets containing milled oilseeds on the fermentation parameters and amount of fatty acids (FA) in the effluent. High-forage diets containing no oilseeds (control diet (CD)) or 10% oilseed meal from rapeseed (RS), sunflower seed (SS), or flaxseed (FS) were used on a dry matter (DM) basis. No differences in DM digestibility were observed between the diets. Inclusion of SS and FS significantly reduced the pH values of the ruminal fluid, and a significant decline in the ammonia nitrogen (NH3-N) (mg/d) production in effluent was observed in the vessels with SS. Generally, oilseeds in these diets significantly reduced the amount of total fermentation gases (L/d); however, only a tendency toward methane (CH4, %) decrease was detected. The addition of oilseeds also significantly diminished the amount of total volatile fatty acids (VFA) produced (mmol/d). Significant reductions in the amounts of saturated FA in the vessels with RS and FS were observed compared with the CD and a significantly higher amount of monounsaturated fatty acids (MUFA) was noted in the vessels with RS. An increased amount of polyunsaturated fatty acids (PUFA), compared with the CD, was statistically significant only in the vessels with FS.Keywords: Flaxseed, high-forage diet, methane, rapeseed, sunflower see

European Economic Crisis and Its Impact on Economy of the Czech Republic and Economic Situation of Chosen Company

katedra: KEK; přílohy: 2 CD ROM (v každé práci 1 CD); rozsah: 91 s. (126 507 znaků)This graduation thesis focuses on the economic crisis that affected in 2008 - 2010 most countries around the world. The aim is to clarify all possible causes, consequences and measures taken to avert it. The graduation thesis is divided into theoretical and practical. The theoretical part is briefly explained historically the greatest economic recession in the 30years and its possible connection with the financial and economic crisis in the period 2008- 2010.It is studied the impact of the crisis on selected European countries and some detail its progress in the Czech Republic. Is also briefly outlined the possible development of the Czech economy, according to estimates of international institutions. In the practical part of the work is first paid attention to the development of automotive markets, and then the company ŠKODA AUTO, a. s., which is the largest domestic manufacturer of automotive vehicles. Developments during the crisis, the company recorded chronologically, by individual years and explained on selected economic indicators.Diplomová práce se zaměřuje na hospodářskou krizi, která postihla v letech 2008 - 2010 většinu států po celém světě. Cílem je objasnění všech možných příčin, důsledků a opatřeních přijatých na její odvrácení. Diplomová práce je rozdělena na část teoretickou a praktickou. V teoretické části je krátce vysvětlena historicky největší hospodářská recese ve 30. letech a její možné souvislosti s finanční a hospodářskou krizí v období 2008 ? 2010. Dále je zkoumán dopad krize na vybrané evropské státy a podrobněji vysvětlen její průběh v České republice. Krátce je také nastíněn možný vývoj české ekonomiky dle odhadů mezinárodních institucí. V praktické části práce je nejprve pozornost věnována vývoji automobilových trhů a poté společnosti ŠKODA AUTO, a. s., která je největším tuzemským výrobcem automobilových vozů. Vývoj během krize je ve společnosti zachycen chronologicky, dle jednotlivých let a dále vysvětlen na vybraných ekonomických ukazatelích

Effects of drying procedures on chemical composition and nutritive value of alfalfa forage

The effects of various drying procedures of alfalfa forage were evaluated on chemical composition, in vitro neutral detergent fibre (NDF) and dry matter (DM) digestibility, in situ DM, organic matter and crude protein (CP) degradability. The alfalfa had been harvested in the spring growth (early bud and flowering) and first regrowth (late bud and late flowering) periods. The samples were dried at 30 °C (T30), 40 °C (T40), 50 °C (T50), 60 °C (T60) and 100 °C (T100) in a forced-air oven or frozen for one month and then freeze-dried (TFD) or oven-dried at 50 °C (TFREE). Another drying procedure included pre-treatment by heating in a microwave oven (TMO) or in a forced-air oven at 100 °C for 1 hour (T100+50) and then oven-dried at 50 °C. The freeze-drying method was chosen as a reference method. Freeze-dried samples had the lowest NDF, acid detergent fibre (ADF), acid detergent lignin (ADL), neutral detergent insoluble protein (NDIP) and acid detergent insoluble protein contents (P <0.05). Additionally, freeze-dried products had the highest CP, in vitro true digestibility of DM and CP degradability values (P <0.05). There was no added benefit of the TMO in the chemical composition, in vitro digestibility or in situ degradation compared with T50. This study showed that T50 can yield chemical composition, in vitro and in situ results that are similar to those obtained with the freeze-drying method and that this procedure is useful for forage analyses and evaluation.Keywords: freeze-drying, insoluble nitrogen, in vitro digestibility, oven-drying, ruminant

Room temperature methoxylation in zeolites: insight into a key step of the methanol-to-hydrocarbons process

Neutron scattering methods observed complete room temperature conversion of methanol to framework methoxy in a commercial sample of methanol-to-hydrocarbons (MTH) catalyst H-ZSM-5, evidenced by methanol immobility and vibrational spectra matched by ab initio calculations. No methoxylation was observed in a commercial HY sample, attributed to the dealumination involved in high silica HY synthesis
