Ruminal dry matter degradability of treated soybean meal as source of escape protein

RS Nobar


In order to study rumen degradation of dry matter for treating soybean meal with black liquor as source of xylose and microwave radiation, an experiment in nylon bag technique was performed. Samples for treating soybean meal for 0, 2, 4, 8, 16, 24 and 48 h in the rumen of three Taleshi male cows were incubated. Soybean meal samples treated with black liquor and microwave radiation decreased water soluble protein fraction (a) and increased slowly protein degradation fraction (b); and treatment with 6% black liquor and 4 min microwave radiation have suitable protection against the soybean meal dry matter degradability.

Key words: Soybean meal, black liquor, microwave radiation, nylon bags.
