Agriculture crop residues and by-product processing were used to make the complete feed pellet, containing 12% of crude protein (CP) and 62% of total digestible nutrients (TDN). Rumen fluid for in vitro dry (IVDMD) and organic matter digestibility (IVOMD) and in vitro gas production was collected from 2 rumen fistulated Ongole Crossbred cows aged 2–3 years. The 0, 0.5, 1.0, 1.5 and 2.0% (volume/weight) formaldehyde concentrations were applied for making the UDP, namely: K-0, K-0.5, K-1.0, K-1.5 and K-2.5 respectively. The protection levels of soybean meal in UDP processing were tested on in vitro dry and organic matter degradability. The best UDP was used to supplement complete feed pellets at levels of 0, 2.5, 5.0, 7.5 and 10.0% dry matter (v/w) e.g. S-0, S-2.5, S-5.0, S-7.5 and S-10 and subjected to in-vitro gas production to measure rumen microbial activity through gas production, microbial protein synthesis and volatile fatty acid production and proportions. Data were subjected to Oneway ANOVA using Completely Randomized Design. The differences found between mean were tested by Duncan's Multiple Range Test. Results showed that IVDMD of unprotected soybean meal (K-0) was significantly higher (P<0.05) than K-0.5, and the K-0.5 was higher (P<0.05) compared to K-1.0, K-1.5 and K-2.0. IVDMD of unprotected soybean meal was higher (P<0.05) thanRead More
