SUMMARYIn the current Dutch protein evaluation system (the DVE/OEB1991system), two characteristics are calculated for each feed: true protein digested in the intestine (DVE) and the rumen degradable protein balance (OEB). Of these, DVE represents the

The efficiency of N utilization in ruminants is typically low (around 25%) and highly variable (10% to 40%) compared with the higher efficiency of other production animals. The low efficiency has implications for the production performance and enviro

This study focussed on the complex regulation of lipid metabolism in the mammary gland of cows and the association between milk fatty acid (FA) profile and the expression of lipogenic genes in individual cows. Changes in FA profile were found to be a

The amount of rumen fermentable organic matter (FOM) can be calculated using tables, taking into account the amount of digestible organic matter, the content of fat and fermentation products, and the amount of starch and protein escaping rumen fermen

The amount of microbial protein leaving the rumen is considered as a function of the amount of rumen-fermentable organic matter (FOM) in the rumen. FOM can be calculated using tables, or estimated by in situ incubation, but both methods have some dra

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

The purpose of this study was to improve the prediction of the quantity and type of Volatile Fatty Acids (VFA) produced from fermented substrate in the rumen of lactating cows. A model was formulated that describes the conversion of substrate (solubl

Five dairy cows fitted with large rumen cannulae were fed diets of 23 pelleted concentrate containing five graded levels of starch between 8 and 32%. Intake declined at five equal intervals from 19.4 kg organic matter per day in early lactation to 4.

Four cows with rumen cannulae were fed twice daily on totally mixed diets containing equal amounts of hay crop silage and maize silage plus a mixture of maize gluten feed, beet pulp and brewers' grains. Diets contained wet ensiled (WET) or dry (DRY)

The objectives of this study were: 1) to determine if a correlation exists between rumen odd and branched-chain fatty acids (OBCFA, i.e., C(15:0), iso C(15:0), anteiso C(15:0), C(17:0), iso C(17:0), anteiso C(17:0), and C(17:1)), uracil, and purine b
