Determination of processed soybean meal degradability by <i>Pinus eldarica</i> methanol extract


R Salamatdoust

Abstract

Protected soybean meal is an important part of high producing dairy cow diet and many methods are used for its safe and economic processing. Pinus eldarica contains xylose and resins and results show that these components could affect dry matter and crude protein degradability. This is the first time a study is being carried out to investigate the effect of this plant extract on protein source. This experiment was performed using the nylon bag technique. Samples for treating soybean meal for 0, 2, 4, 8, 16, 24 and 48 h in the rumen of three male Ghezel male sheep were incubated. Results indicated that the addition of this plant extract to soybean meal samples could affect dry matter and crude protein degradability and thus protect proteins from rumen degradation.

Key words: Pinus eldarica, soybean meal, degradability, protection.
