描述This book is intended to be a companion volume to ‘Protein Nutrition in Ruminants‘ (1982, Academic Press), which emphasized both the role of proteins and new systems for their evaluation. Here the focus is on energy-yielding nutrients and problems involved in evaluating them. Nonetheless in both volumes there is explicit recognition of the interdependence of energy and protein nutrition. I have not attempted to review comprehensively all the literature relating to ruminant energy nutrition and must apologize to colleagues whose work is not fully reported. Where possible tables and figures are taken from the studies of our group at the Rowett Research Institute since, if for no other reason, I am most familiar with these data. I have first considered the nutrition of the newborn and have stressed the role of behaviour ‘in determining whether nutrients enter or bypass the rumen. The development of the rumen, the of anaerobic fermentation and the roles of various principles . species of rumen bacteria, protozoa and fungi in relation to different substrates, are summarized. This is followed by accounts of the factors affecting the utilization of different substrates and the v vi Prefac

Feed Evaluation, Past and Present, references extending back to observations on the value of different feeds as early as 2500 BC. Flatt (1988) also summarized many historical aspects of feed evaluation. There is therefore no need for an elaborate account here.

Springer Lexikon Kosmetik und Körperpflegee material . contained in roughage contributes little to rumen fill. In contrast, the insoluble but fermentable material . contributes to the volume occupied initially, and the rate constant . determines the duration of its diminishing occupation. The insoluble and indigestible material, 100 (. + .), occupies a constant volume until voided.

Nutrient Supply to the Newborn Ruminant,the colostrum, the newborn’s first energy source, with intestinal cell permeability to large molecules. At the same time, large amounts of globulins obtained from the colostrum help to protect against prevalent pathogens while the immune system is developing.
