This specially curated collection features four reviews of current
and key research on metabolic disorders in dairy cattle. The first
chapter reviews the prevalence, etiology and effects of ruminal
acidosis, as well as ways to counteract it through regulation of
ruminal pH. The chapter includes a case study on subacute rumen
acidosis (SARA) in the post-partum phase of the transition period.
The second chapter assesses the main pathways for rumen
fermentation which is a major factor in efficient transformation of
nutrients. It discusses factors influencing the efficiency of
microbial growth as well as the interactions between rumen energy
and nitrogen metabolism in ensuring efficient digestion and
avoiding metabolic disorders. The third chapter investigates the
genetics of improving feed intake efficiency which has significant
potential in reducing metabolic disorders. The chapter reviews key
challenges in developing genomic selection indices for feed intake,
including recording feed intake, pooling genetic data and
establishing genomic breeding values for feed efficiency. The
fourth chapter discusses how cereal grains impact feed efficiency
in cattle. It reviews how cereal grains can be used to improve feed
efficiency and the microbiology of cereal grain fermentation. The
chapter also discusses ways of avoiding acidosis and other negative
feed effects.
Eine oekonomische und rechtliche Analyse der derzeitigen
Besteuerung sowie der Entwurf von Reformvorschlagen erfordern ein
Leitbild fur die optimale Struktur des Steuersystems. In der
aktuellen Diskussion haben sich die Gewichte zugunsten einer
Besteuerung des Konsums verschoben. Der Konsum ist in einer
marktwirtschaftlichen Ordnung unter Effizienz- und
Gerechtigkeitsaspekten eine ideale Steuerbemessungsgrundlage.
Erstmals erscheint damit im Weltmassstab eine Harmonisierung von
Besteuerungsidealen moeglich. Im vorliegenden Band werden die Vor-
und Nachteile einer konsumorientierten Neuordnung des Steuersystems
von fuhrenden Wissenschaftlern des In- und Auslandes diskutiert.
