Objective:1. The purpose of this experiment was to investigate and compare the in vitro digestibility of rice straw, corn stalks and sugar cane tailings treated with urea ammonization, conventional silage, and lactic acid bacteria to determine the most effective approach.2. To determine the most appropriate way of dealing with microorganisms by investigating and comparing three methods of in vitro digestibility by adding lactic acid bacteria, probiotics, and EM of microbial agents to rice straw, corn stalk, and sugar cane tailing.Methods:Trial 1: The straw, corn stalk, sugar cane tailing were localized, then urea ammonization, conventional silage, and lactic acid bacteria silage are added to the three products, with a corresponding control group of untreated straw feed.Trial 2: The straw, corn stalk, sugar cane tailing were localized, then individually treated with three formulas; The first was a base of 5% corn flour, 5% wheat bran, 1% soybean meal, 0.5 % urea; the second was lactic acid bacteria silage, the third was probiotics microbe store. These were then placed in the liquid-EM Storage experiment. The corresponding straw feed control group was treated with 5% corn flour, 5% wheat bran, 1% soybean meal, 0.5% urea, with the bacteria not added directly to the silage.Results:Trail 1: Of the three in vitro digestibility tests, the findings showed that urea ammonization treatment of straw feed had the best result. The in vitro digestibility of urea ammonized straw's dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid was 58.10%, 47.50%, 46.21%, 49.06%, 49.84%, and 32.81%. Compared with the control group, the dry matter, the NDF, acid detergent fiber, cellulose, hemicellulose and lignin acid digestibility increased by 33.41%, 25.36%, 17.79%, 47.55%, 40.75%, and 49.48%.In vitro digestibility of urea ammonization of corn stalk dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid were 61.02%, 51.89%, 55.65%, 57.17%, 41.59% , and 37.95%. Compared with the control group, dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid digestibility increased by 35.51%, 32.91%, 42.04%, 24.31%, 64.45%, and 78.00%.Urea ammonization of sugar cane tailing's dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid in vitro digestibility were 55.71%, 48.23%, 46.82%, 42.03%, 48.62% , and 32.75%. Compared with the control group, dry matter, the NDF, acid detergent fiber, cellulose, hemicellulose and lignin acid digestibility increased by 41.11%, 31.02%, 40.73%, 64.82%, 23.84%, and 82.15%.Trail 2: The results showed that the highest in vitro digestibility and most appropriate way of dealing with micro-organisms of the three straws was adding 5% corn flour, 5% wheat bran, 1% soybean meal, and 0.5% urea plant silage lactic acid bacteria. The highest in vitro digestibility was Lactobacillus plant silage of straw, with dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid washing increases of 55.99%, 47.40%, 46.03%, 47.41%, 49.74%, and 31.22% respectively. Compared with the control group, dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid digestibility increased by 22.84%, 24.05%, 17.09%, 29.08%, 38.55%, and 25.89%. Lactobacillus plant silage corn stalks also increased in vitro digestibility, with dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid washing increases of 59.18%, 49.71%, 53.33%, 55.55%, 41.56%, and 33.60% respectively. Compared with the control group, dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid digestibility increased by 12.04%, 13.13%, 14.00% , 20.66%, 11.12%, 22.81%. Lactobacillus plant sugar cane tailings silage also had a higher in vitro digestibility, with dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid washing of 53.93%, 47.51%, 45.37%, 39.93%, 49.78%, and 30.59% respectively. Compared with the control group, dry matter, NDF, ADF, cellulose, hemicellulose and lignin acid digestibility increased by 20.27%, 15.99%, 22.29% , 19.05%, 10.47%, and 33.69%.Conclusion:Under the conditions of this experiment, the best approach was using ammonization silage for straw, corn stalk, and sugar cane tailing.
