The objective of this experiment was to determine if transcript abundance of genes involved in metabolic pathways in adipose and liver tissue could provide some explanation for the low efficiency with which ME in autumn pasture is used for BW gain. Nonlactating, pregnant (208 ± 19 d of gestation or approximately 75 d precalving) dairy cows (n = 90) were randomly allocated to either a control di...

This study was carried out to estimate the relevance of biological supplementation in improving economic efficiency anaerobic digestion (AD). Three kinds silages—maize, grass, and igniscum—were initially inoculated with digestate then supplemented one four vaccines containing different bacteria species (APD®, PPT®, JENOR®) or a yeast mold mixture (HAP®). In addition, each plant silage fermented...

Perennial herbaceous crops can become the main basis for renewable energy production in agricultural ecosystems in future. To determine the plant species that are the most suitable for biomass production, their biological peculiarities and productivity, biochemical composition and thermophysical properties, social and ecological impact must be investigated thoroughly. The local varieties of per...

This research was conducted to investigate in situ degradation characteristics of maize, sorghum and sorghum-Sudan grass hybrids. whole plant of maize (TTM-815, DK-711), sorghum (SS-506, FS-5) and sorghum × Sudan grass hybrids (P-988, Grazer N2) were grown under semi-arid conditions and harvested at different maturity stages (mid-flowering (MF), milk-line (ML) and hard-dough (HD)) and ensiled. ...

The common smut of corn, caused by Ustilago maydis, reduces the yield and quality maize forage. When heavy infestations corn occur, grain yields can be so severely decreased that most viable economic alternative may to harvest ensile crop. Only a couple studies have attempted investigate influence aerobic exposure on nutritive value stability silage, which is prepared from smut-infected maize. ...

A well-balanced microbial consortium is crucial for efficient biogas production. In turn, one of a major factor that influence on the structure of anaerobic digestion (AD) consortium is a source of microorganisms which are used as an inoculum. This study evaluated the influence of inoculum sources (with various origin) on adaptation of a biogas community and the efficiency of the biomethanizati...

E-mail address: [email protected] Silage has been the prevailing type of preserved forage for cattle feeding in many countries. Carry-over of some components from silage to cow’s milk has been thus of concern. Silage is a richer source of available provitamins A, o...

BACKGROUND The growing concern regarding the use of agricultural land for the production of biomass for food/feed or energy is dictating the search for alternative biomass sources. Photosynthetic microorganisms grown on marginal or deserted land present a promising alternative to the cultivation of energy plants and thereby may dampen the 'food or fuel' dispute. Microalgae offer diverse utiliza...

Biogas plants fuelled with renewable sources of energy are a sustainable means for power generation. In areas with high infestation levels with the European corn borer, Ostrinia nubilalis (Hbn.), it is likely that transgenic Bt-maize will be fed into agricultural biogas plants. The fate of the entomotoxic protein Cry1Ab from MON810 maize was therefore investigated in silage and biogas productio...
