AbstractThis study assessed the contribution of chemical constituents used in the in vitro technique by Tilley and Terry on digestibilities of five species of plants. Apparent digestibility was lowest, 28-29%, for water alone, buffer alone, and buffer plus pepsin. Dry matter loss increased to 32-33% with either buffer + alcohol + HCl or buffer + alcohol + HCl + pepsin. Highest apparent digestibility, 44%, was reached with the addition of white-tailed deer inoculum. HCl contributed significantly to digestion while pepsin did not. Degree of digestion varied among the five species of plants tested.
