The substitution of soybean meal for urea: the effect on the ammonia content of the rumen fluid, the N flow in the duodenum, the nitrogen and energy balances and the milk production



The substitution of soybean meal for urea: the effect on the ammonia content of the rumen fluid, the N flow in the duodenum, the nitrogen and energy balances and the milk production



Archiv für Tierernahrung 34(4): 286-294



The test diets were of maize silage with urea or with soyabean meal. In 2 dry cows with permanent rumen cannula ammonia in rumen fluid was considerably more with urea than with soya. With low nitrogen intake, duodenal N flow, measured in 2 dry cows with re-entrant cannula, was about the same with both supplements, but with increased N intake amount of N reaching the intestine was clearly more with soya than with urea.
