Free AA in plasma and muscle were monitored in 36 dairy cows from 2 wk before until 15 wk after parturition. Cows were kept indoors and fed individually. The AA concentrations in plasma from 6 to 15 wk of lactation were compared with precalving conce

Three rumen fermentation studies in combination with three feeding trials were carried out to investigate the effect of partial replacement of heavily fertilized perennial ryegrass by low protein feedstuffs on pH and concentrations of VFA and NH3 N i

Samples of lupines, peas, rapeseed meal and field beans were ground to pass through a 1 mm screen, treated with 0, 10, 20, 30 and 40 g formaldehyde kg−1 crude protein (CP) and incubated in situ for 12 h in the rumen of four cows, surgically prepare

Samples of a totally mixed ration and of soybean hulls were incubated in nylon bags in the rumen of four cows. Incubation times were 3, 6, 12, 24, 48 and 280 h. The 3- to 48-h incubations and determination of solubility were repeated in seven periods

The interaction between the quality of grass silage and starch supplementation on ruminal digestion was studied in an experiment with a 2 x 2 factorial design using four dairy cows. Treatment factors were grass silage harvested after either 21 or 37

The effects of the maturity of grass prior to ensiling and the supplementation of starch to grass silage on apparent digestibility, degradability, rumen content, and feed intake by dairy cows were investigated using a Latin square design. Treatments

Changes in digestion and AA supply in dairy cows were studied when fresh grass was partly replaced by concentrate mixtures based either on corn starch or sugar beet pulp fiber. Treatments were tested in a Latin square utilizing three lactating cows w

Ruminal degradation characteristics of neutral detergent fibre (NDF), starch and crude protein (CP) in concentrate ingredients were estimated in dairy cows using nylon bag incubations. Soluble fraction (starch, CP), undegradable fraction (NDF, CP), l
