Four cannulated dairy cows in early lactation were offered grass‐silage‐based diets, designed to contain either 20 or 30% starch or sucrose on a DM basis, in a 4 x 4 Latin square design. In order that the diets had the same fibre content, pure wheat starch and pure sucrose were utilized. No...
Ruminai digestion and passage rates and digestibility of NDF were measured in vivo with four cannulated dairy cows in early lactation in a 4 x 4 Latin square design. In vivo rates of digestion and passage were determined using the rumen evacuation technique. Rumen digestion characteristics of...
Data on 216,428 Danish Red, 798,152 Danish Friesian and 232,953 Danish Jersey cows were used to estimate phenotypic and genetic parameters for actual and production‐corrected survival traits and for milk production. Genetic effects of imported breeds were also estimated. Phenotypic trends in...
The portal recovery of SCFA (short‐chain fatty acids) infused intraruminally as a single load was investigated in sheep adapted to a hay (H) or a concentrate/straw (CS) diet. The treatments were control (saline), 1.4 mol and 2.4 mol of SCFA (in % 65:20:15 acetate, propionate and butyrate). Three...
A low‐protein diet supplemented with essential amino acids to meet the estimated requirements for essential amino acids in growing mini and with a total amino acid nitrogen content of 65–75% of the requirement, was fed to male mink kits during the growing period from weaning to pelting. The...
The effects of a top nest box on production‐related parameters and behaviour were examined in a field trial on four groups of 24 growing blue fox cubs from weaning until pelting. Control animals had a wire mesh platform. There were no differences in weight gain between groups. Dirtiness of nest...
