Urease activity in soybean meal products

In situ Evaluation of Ruminal Degradability and Intestinal Digestibility of Sunflower Meal Compared to Soybean Meal

The aim of this study was to compare the nutritional value of sunflower meal (SFM) and soybean meal (SBM) protein by determining both its ruminal degradability and intestinal digestibility. Three non lactating Jersey cows fitted with a rumen and T-type duodenal cannulas were used to estimate rumen degradability and intestinal digestibility of SFM and SBM dry matter (DM) and crude protein (CP). ...

Replacing Conventionally Processed Soybean Meal with Extruded/Expelled Soybean Meal in Swine Diets

Soybean leaf urease: a seed enzyme?

The soybean (Glycine max L. [Merrill]) var Itachi has 0.2 to 0.3% the urease activity found in developing embryos of a normal line, Prize. The hydroxyurea sensitivity and pH preference of this basal seed urease indicate that it represents a unique enzyme rather than an unusually low level of the normal seed urease. Itachi's seed urease is less sensitive to hydroxyurea inhibition (65-80% inhibit...

Extraction and Antioxidant Activity of Soybean Saponins from Low- temperature Soybean Meal by MTEH

The research aimed at developing an optimal procedure for the extraction of soybean saponins from lowtemperature soybean meal with microwave treatment combined with enzymatic hydrolysis (MTEH), and studied the antioxidant activity of soybean saponins. The result shows that the optimal parameters of microwave treatment, determined with the orthogonal array design method, were the medium fire of ...

Nutritional Value of Soybean Meal

Protein feeds in the European Union (EU) cover only 25% demand for protein, what oblige the particular members to import feeds with a high protein content, where the main place have soybean meal. The share of this feed in total quantity of feeds utilization in EU is about 9%. Yearly consumption of soybean meal in EU is about 32mln ton, from what 5.6% it falls on Poland (Rynek Pasz, 2010). Polan...
