Formaldehyde treatment suppresses ruminal degradation of phytate in soyabean meal and rapeseed meal.
Most of the P in oilseed meal is in the form of phytate P, and phytate forms complexes with protein. Phytate P has been considered to be absorbed easily in ruminants because of phytate degradation in the rumen. Treatment of oilseed meals with formaldehyde improves the nutritional value of protein through suppressing its ruminal degradation. The present experiment was conducted to study the effe...
متن کاملInvestigating Ruminal Nitrogen Metabolism
Nitrogen losses from dairy production have negative impacts on the environment and on production economics. In Northern Europe, dairy cattle are mainly fed forage-based diets supplemented with protein feeds such as rapeseed meal. This thesis sought to develop and evaluate new methods for forage protein evaluation and to improve the value of locally produced protein feeds. Ruminal metabolism of ...
متن کاملMetabolic fates of ammonia-N in ruminal epithelial and duodenal mucosal cells isolated from growing sheep.
The objective of this experiment was to determine the capability of ruminant gut tissues to detoxify ammonia-N using short-term incubations of isolated cells in vitro. Ruminal epithelial cells (REC) and duodenal mucosal cells (DMC) were isolated from growing Texel-Polypay ram lambs (n = 4) fed a pelleted forage:concentrate-based diet. Immediately after isolation, primary cells were incubated fo...
متن کاملSupplementing barley or rapeseed meal to dairy cows fed grass-red clover silage: I. Rumen degradability and microbial flow.
The present study was conducted to measure the flow of microbial and nonmicrobial N fractions entering the omasal canal of lactating dairy cows fed grass-red clover silage supplemented with barley and rapeseed meal. Four ruminally cannulated Finnish Ayrshire dairy cows were fed, in a 4 x 4 Latin square design, grass-red clover silage alone or supplemented with (on DM basis) 5.1 kg/d of barley, ...
