Abstract :This study was conducted to determine the effects of soybean meal insert ignore into journalissuearticles values(SBM); treated with formaldehyde on rumen fermentation pattern, microbial protein synthesis, amount of by-pass protein, and amino acid absorption from small intestines. Four 1-year-old rams with ruminal, duodenal, and ileal cannulas were fed 800 g of dry clover plus a concentrate mixture containing 100 g of SBM treated with 0%, 0.3%, 0.6%, and 0.9% formaldehyde. The amount of crude protein passed through the duodenum was not affected by the formaldehyde treatment; however, the amount of microbial protein decreased in rams fed with SBM treated with both 0.3% and 0.6% formaldehyde insert ignore into journalissuearticles values(P < 0.05);. Digestibility of acid detergent fibre insert ignore into journalissuearticles values(ADF); and neutral detergent fibre insert ignore into journalissuearticles values(NDF); in the duodenum and ileum did not differ by treatments. In the rams fed SBM treated with both 0.3% and 0.6% formaldehyde, absorbability of arginine, histidine, leucine, methionine, phenylalanine, and valine insert ignore into journalissuearticles values(essential amino acids);, as well as alanine and aspartic acid insert ignore into journalissuearticles values(non-essential amino acids); significantly increased, whereas tyrosine absorbability notably decreased insert ignore into journalissuearticles values(P < 0.05);. Formaldehyde treatment increased the absorbability of other essential amino acids insert ignore into journalissuearticles values(leucine and valine); and non-essential amino acids insert ignore into journalissuearticles values(serine and tyrosine); in the ileum insert ignore into journalissuearticles values(P < 0.05);. Increasing the percentage of formaldehyde linearly increased total essential amino acid absorption in the duodenum insert ignore into journalissuearticles values(P < 0.05);. In conclusion, 0.3% and 0.6% formaldehyde treatment enhanced the bioavailability of protein in SBM.
