Determination of chemical composition and nutritional value of Ziziphus jujube mill foliageusing in vitro methods

This Research was conducted to study the chemical composition and nutritional value of Ziziphus jujube mill foliage using of gas production method and nylon bag. Two cow fistulated were fed with forage and concentrate for maintanence towice days. Degradability of DM and NDF measured by gas production method and nylon bag. Samples incubated in times of 2،4،8،16،24،36،48،72 and 96 hours for gas test and nylon bag. The amounts of DM، OM، Ash، EE،CP and NDF of Ziziphus jujube mill foliage were 45، 91، 9، 5، 15. 1 and 32، percentage respectively. Calcium was 3. 6 percentage. Coefficients of a and b for DM were 0. 31 and 0. 35 and for NDF were 0. 18 and 0. 34. Total tannen of Ziziphus jujube mill foliage was 3. 2 percentage. Gas test showed that digestion of souleble fraction and insouleble but digestible was 49. 64 percentage.
