Journal ArticleDOI
Influence of plane of nutrition and diet composition on rumen fermentation and energy utilization by dairy cows
TL;DR: It is suggested that both the reduction in milk fat concentration and the increase in milk yield in response to reductions in the fibre content of diets may be independently related to the increased in the proportion of propionate in the rumen VFA.

Diet Check: a tactical decision support tool for feeding decisions with grazing dairy cows
TL;DR: A simple tactical decision support tool, ‘Diet Check’, developed to help dairy farmers in the NIRV estimate whether their cows are consuming sufficient metabolisable energy (ME), crude protein (CP) and neutral detergent fibre (NDF) for a specified level of milk production.

Performance of dairy cows offered isonitrogenous diets containing urea or fishmeal in early and in mid-lactation
TL;DR: A major effect of replacing urea-N with fishmeal-N was to increase digestible organic matter intake (DOMI) and differences in DOMI between treatments in Expt 1, Part 1, accounted for observed differences in performance.
Journal Article
Micronutrients and Animal Nutrition and the Link between the Application of Micronutrients to Crops and Animal Health
TL;DR: The aim should be to only use supplementation with micronutrients where it is necessary; that is, where an actual or likely deficiency has been diagnosed and the supplement used should be cost effective and appropriate to the farming system in question.

A model of nutrient utilization and body composition in beef cattle
TL;DR: In this article, a simple dynamic model of metabolism in growing beef cattle is described; the scheme is based on carbon and nitrogen fluxes There are six state variables, three relating to blood metabolite levels and three to body composition.
