Respiration experiments with high-yielding dairy cows in Northern Ireland have shown higher energy maintenance requirements than those used in the requirements standards of, e.g. France, UK, USA and Germany. Therefore, the current net energy for lact

Summary The objective of this study was to determine the changes to residual plant feeding value of early- and late-maturing maize varieties. The influence of the cell wall carbohydrate composition, in terms of neutral and acid detergent fibre (NDF a

Summary The effects of non-starch-polysaccharide-degrading enzymes, added to a maize silage- and grass silage-based total mixed ration (TMR) at least 14 h before feeding, on the rumen bacterial population were investigated. Six non-lactating Holstein

Wilting grass prior to ensiling generally increases the dry matter (DM) intake but the effect of wilting on animal performance is still poorly understood. There is a need to improve understanding of the effects of wilting on the nutritional component

The common carp ( Cyprinus carpio ) is an agastric fish, meaning absorption of nutrients is highly dependent on the rate of feed passage in the gut. Two diets and 3 feeding strategies were used in a 2 × 3 factorial experiment, conducted to determine

Rumen insoluble feed crude protein (CP) escaping degradation (RUP) was estimated from a variety of forages using two in vitro procedures: the Cornell protein fractionation procedure and the enzymatic degradation procedure by Streptomyces griseus prot

As protein evaluation systems are evolving, they are increasing in their sophistication and complexity. In almost all systems an estimate of microbial crude protein (MCP) and ruminally undegraded feed CP (RUP) must be available. A problem lies in the

The burbot (Lota lota) is the only gadoid fish in freshwater and could be an interesting candidate for an aquaculture production. The objective of this study was to develop suitable rearing techniques for early life stages of burbot larvae under inte

Milk fatty acid (FA) profile is a dynamic pattern influenced by lactational stage, energy balance and dietary composition. In the first part of this study, effects of the energy balance during the proceeding lactation [weeks 1–21 post partum (pp)]

Summary This study was performed to assess the effects of rumen-protected conjugated linoleic acid (CLA) on hepatic lipid metabolism in heifers. In particular, it was of interest whether feeding CLA causes development of fatty liver as observed recen
