In Vitro Rumen Fermentation

A study was carried out to determine the effect of medicinal plants from Enugu (En) and Kaduna (Kd) States on in-vitro rumen fermentation and methanogenesis. Twelve medicinal plants comprising herbs and spices were collected from En and Kd States, respectively. The chemical composition and cell wall component (NDF, ADF and hemicellulose) of the plants were determined. The samples were evaluated in an in-vitro study at an inclusion level of 10 mg/ 200 mg substrate. The experiment was laid out in a factorial arrangement and executed as a randomized complete block design with incubation done in batches. At the completion of the 24-hour incubation period, total gas volume (GV), dry matter digestibility (DMD), fermentation efficiency (FE) and CH were determined while organic matter digestibility 4 (OMD), short chain fatty acids (SCFA) and metabolisable energy (ME) were estimated from established equations. The chemical composition indicated range values of 72.82 (Allium sativum, En) - 95.73% (Aloe barbadense, Kd) for DM, 7.01 (Aframomum  elegueta, En) – 30.59% (Allium sativum, En) for CP, 8.94 (Allium sativum, Kd) – 81.41% (Cymbopogon citratus, En) for NDF, 3.58 (Allium sativum, En) – 63.64% (Xylopia aethiopica, En) for ADF, 1.79 (Allium cepa, Kd) - 48.77 % (Aframomum melegueta, En) for hemicellulose, 2.64 (Aframomum melegueta, En) – 22.51% (Ageratum conyzoides, Kd) and 77.49 (Ageratum conyzoides, Kd) – 97.36% (Aframomum melegueta, En) for ash and OM, respectively. The effect of location on chemical composition varied among the plant types with significantly higher (P < 0.05) levels of CP in most of the Kd plants. The range for GV, DMD, CH 4 percentage, CH reduction, FE, OMD, SCFA and ME were 85.00 (Ageratum conyzoides, Kd) 4 - 149.49 mL/g DM (Aloe barbadense, Kd), 525.50 (Sida acuta, Kd) - 764.50 g/Kg DM (Aframomum melegueta, En), 45.75 (Allium sativum, En) - 72.59% (Aframomum melegueta, Kd), 2.36 (Allium cepa, Kd) - 32.86% (Zingiber officinale, Kd), 4.23 (Sida acuta, Kd) - 8.12 (Ageratum conyzoides, Kd), 45.83 (Ageratum conyzoides, Kd) – 57.18% (Cymbopogon citratus, Enugu; Aloe barbadense, Kd), 0.35 (Ageratum conyzoides, Kd) - 0.66 mmol/200 mg DM (Cymbopogon citratus, En) and 5.18 (Ageratum conyzoides, Kd) – 6.93 MJ/Kg DM (Cymbopogon citratus, En; Aloe barbadense, Kd) respectively. Allium sativum bulbs, Zingiber officinale rhizomes, Cymbopogon citratus and Sida acuta (both locations) reduced CH production without adversely affecting the desired fermentation parameters indicating 4 that the medicinal plants have methane reducing potential.

The study presents 175 artefacts from the settlement center in Gniezno – beads and rings. The materials come from settlement levels from around the mid-10th to the 13th centuries. The latest chronological findings based on 14C dating have made it possible to refine the dating, especially of the early settlement levels of the stronghold, where the vast majority of glass artefacts come from. Threeba sic groups of beads have been distinguished based on the technique of their production – beads made of a drawing a tube, the technique of winding a glass strip, as well as casting and sintering. The results of 7 physico-chemical analyzes of the glass composition (performed with the X-Ray Fluorescence, XRF method) are presented. Physicochemical analyzes of the chemical composition of the tested beads made it possible to determine the technological group and the type of glass. An attempt was made to explain the origin of the starting material (glass) for jewelery. A comparative analysis made it possible to indicate in a general manner possible manufacturers and to outline the likely directions of the influx of these glass ornaments to Gniezno.

Abstract. In this paper, the reasons for geophagy (the eating of rocks by wild herbivores) in two regions of the Eastern Sikhote-Alin volcanic belt are considered. The mineralogical and chemical features of the consumed rocks, and also the geological conditions of their formation are investigated. A comparative analysis of the mineral and chemical composition of the consumed rocks and the excrement of the animals, almost completely consisting of mineral substances, is carried out. It is established that the consumed rocks are hydrothermally-altered rhyolitic tuffs located in the volcanic calderas and early Cenozoic volcano-tectonic depressions. They consist of 30–80 % from zeolites (mainly clinoptilolites) and smectites, possessing powerful sorption properties. According to the obtained data, the main reason for geophagy may be connected with the animals’ urge to discard excessive and toxic concentrations of certain elements that are widespread in specific habitats and ingested with forage plants.
