FERMENTATION IN THE RUMEN OF THE SHEEP

III. INTERMEDIATE STAGES IN THE FERMENTATION OF WHEATEN

HAY IN VITRO BY MICRO-ORGANISMS FROM THE RUMEN

pdf (With One Text-figure)

A previous communication in this series of papers (Gray, Pilgrim & Weller, 1951) gave an account of the fermentation of wheaten hay and lucerne hay by organisms from the rumen of the sheep, in which the overall production of each of the main volatile fatty acids was determined. In view of the complex nature of both the substrate and the mixed population of organisms involved, it was decided to investigate the intermediate stages of the fermentation to determine whether any

important changes take place in the composition or in the rate of production of the mixture of acids.

Method for Measuring Gas Production Kinetics

D.R. Mertens and P.J. Weimer

Introduction (pdf)

Methodology can play a critical role in the measurement of digestion kinetics, especially when the objective is to define kinetic parameters for feeds when formulating rations or modeling animal responses. Measurement of gas production kinetics provides the opportunity to evaluate the rate of digestion of the soluble, more rapidly fermenting fractions of feeds. However, differences among procedures that have little impact on digestion of dry matter after 48 h of incubation may have dramatic effects on fermentation of soluble matter during the first 20 h. Our objective was to develop a method for measuring the kinetics of gas production that would minimize any detrimental effects associated with the in vitro system and provide estimates of digestion kinetics that can be used to both describe feeds for ration formulation systems and provide parameters for models of ruminal digestion.

Introduction

 

Jambi Province is an area situated in the central part of Sumatra Island. Geographically is located between 00 45′ to 20 45′ Latitude South and 1010 10′ to 1040 55′ Longitude East. Jambi Province is separated by Riau Province in the north, Malacca strait in the east, West Sumatra in the west and South Sumatra in the south. The width of Jambi Province is 53.534 km2 that consists of ( more read. pdf).

A Strategy for Reducing Methane Emissions

Judith Bates, AEA Technology plc

ABSTRACT (pdf)

Methane is an important greenhouse gas whose concentration in the atmosphere has more than doubled since pre-industrial times. It is a more potent greenhouse gas than carbon dioxide, but due to its shorter atmospheric lifetime (of 12 years) it is estimated that global emissions would only need to be reduced by about 8% from current levels to stabilize methane concentrations at today’s levels. This is a much smaller percentage reduction than those required to stabilize atmospheric concentrations of the other major greenhouse gases, CO2 and N20.

The main source of methane emissions within the EU is the agricultural sector, where emissions arise mainly from enteric fermentation in ruminant livestock, but also from livestock manure. The other major source is landfills, while coal mining and gas production and distribution are smaller, but still significant contributions. There are a range of possible measures for the reduction of emissions from each of these sectors, varying from technological options such as the collection and combustion of landfill gas, or the recovery and use of methane from animal waste, through to more general measures, often of a longer term nature, such as a reduction in the amount of organic waste going to landfill, or a reduction in livestock numbers. For some sources there are still significant uncertainties in emission factors, which make the development and assessment of abatement options difficult. In addition, there is a lack of data on the cost-effectiveness of many actions and measures. Any strategy for reducing emissions is 246 thus likely to need to combine measures to encourage the deployment of proven techniques, and to encourage research into the cost-effectiveness of options, and to improve knowledge of emissions factors and processes for some sources. This paper discusses the main options for the reduction of methane emissions and briefly summarizes the strategy paper recently prepared on this subject by the European Commission.

BAB III

Rajo Tigo Selo

 

Rabu, 11/06/2008 10:16 WIB

 

 

Rajo Tigo Selo merupakan sebuah institusi tertinggi dalam kerajaan Pagaruyung yang dalam tambo adat disebut Limbago Rajo. Tiga orang raja masing-masing terdiri dari Raja Alam, Raja Adat dan Raja Ibadat yang berasal dari satu keturunan. Ketiga raja dalam berbagai tulisan tentang kerajaan Melayu Minangkabau ditafsirkan sebagai satu orang raja. Itulah sebabnya sejarah mencatat bahwa raja Melayu sewaktu didatangi Mahisa Anabrang dari Singosari yang memimpin ekspesidi Pamalayu bernama Tribuana Raja Mauli Warmadewa. Arti kata tersebut adalah tiga raja penguasa bumi yang berasal dari keluarga Mauli Warmadewa. baca selanjutnya

BAB IV
Yang Di Pertuan Sultan Alam Muningsyah

Rabu, 11/06/2008 10:17 WIB

Tuanku Raja Muning Alamsyah atau juga yang disebut Yang Dipertuan Sultan Alam Muningsyah adalah raja alam Pagaruyung yang secara luar biasa selamat dari tragedi pembunuhan di Koto Tangah, Tanah Datar pada tahun 1809 dalam masa Perang Paderi berkecamuk di Minangkabau. Tahun terjadinya tragedi ini dipertikaikan.

Christine Dobin mencatatkan dalam Kebangkitan Islam Dalam Ekonomi Petani Yang Sedang Berubah, (Inis, Jakarta 1992) tragedi tersebut terjadi pada tahun 1815, sebagaimana yang juga ditulis Rusli Amran dalam Sumatera Barat Hingga Plakat Panjang, (Sinar Harapan, Jakarta 1981). (Baca selanjutnya)

1. Introduction

Rumen liquor has been widely used as inoculum in some in vitro techniques of feed evaluation. This liquor has been firstly used by Tilley and Terry (1963) for their two-step technique of feed evaluation. It was then also applied in the rumen simulation technique (Czerkawski and Breckenridge, 1977) and in the gas producton technique (Menke, et al, 1979 and Theodorou et a, 1994) all over the world. Until now rumen liquor is still the only inoculum used in in vitro technique. (Bahasa Indonesia)
