Journal ArticleDOI
Effect of intraruminal infusion of potassium on the site of magnesium absorption within the digestive tract in sheep
TL;DR: Increase in K intake was associated with a consistent reduction in plasma Mg concentration which was independent of Mg intake, and at high K intake Mg absorption from the rumen was reduced, the amount absorbed ranging from 0·07 g Mg/day at intakes of 1·3 g MG/day and 46 g K/kg DM/day.
Journal ArticleDOI
Effect of the inclusion of tropical tree legumes, Gliricidia sepium and Leucaena leucocephala, on the nutritive value of silages prepared from tropical grasses
TL;DR: It was concluded that tropical grasses can be effectively ensiled by the addition of legumes alone and, with the exception of setaria/gliricidia silages, the resultant silages were of sufficiently high quality to merit their use in tropical animal production systems.
Journal ArticleDOI
Effects of walking speed and forage consumption on energy expenditure and heart rate by Alpine does
TL;DR: Eight nonlactating Alpine does were used to determine effects of standing versus walking at different speeds and interactions between walking speed and forage ingestion on energy expenditure, heart rate, and their ratio.

The utilization of wilted and unwilted silages by lactating cows and the influence of changes in the protein and energy concentration of the supplement offered
F. J. Gordon,A. C. Peoples +1 more
TL;DR: In this article, the authors evaluated eight treatments consisting of two silage types (wilted and unwilted), each offered in addition to supplements containing both two crude protein (CP) levels (160 and 210 g/kg fresh weight) and two energy levels (10·8 and 12·9 MJ metabolizable energy per kg fresh weight).
Economic-environmental modelling of Dutch dairy farms incorporating technical and institutional change
TL;DR: In this article, the authors developed and applied a method to enlighten the consequences of these changing circumstances for dairy farms using a linear programming model of a dairy farm, which contains activities for common production processes on dairy farms like grass and silage maize production and milk production.
