Abstract
The objective of this experiment was to compare the dry matter intake, nutrients digestibility and nitrogen and energy utilization of herbages harvested from turf type mixtures {tall fescue(Rebell Jr.) 40%+ perennial ryegrass(Palmer II) 20%+ Kentucky bluegrass(Newport) 10%+ redtop(Banicuda) 10%+ red fescue(Salem) 10%+ creeping bentgrass(Crenshaw) 10%} and tall type mixtures {orchardgrass(Potomac) 40%+ tall fescue(Fawn) 20%+ Festuloium braunii(Paulita) 10%+ perennial ryegrass(Reveille) 10%+ timothy(Climax) 10%+ red clover(Kenblue) 10%+ alfalfa(Vernal) 10%} by Korean native goats. This experiment was conducted by total collection method in laboratory, 2001. The voluntary DM intake per body weight were slightly higher for turf type mixtures(28.9g) than that of tall type mixtures(26.2g), but there was no significant difference. The digestibility of cellular constituents was slightly higher for turf type mixtures than that of tall type mixtures(p<0.05), but digestibility of DM, NDF and ADF did not differ between two mixtures. The retained nitrogen percent(apparently biological value) was slightly higher for turf type mixtures(56.7%) than that of tall type mixtures(56.4%), but there was no significant difference between two mixtures. Apparently retained digestible energy was slightly higher for turf type mixtures(58.3%) than that of tall type mixtures(57.9%), but there was no significant difference between two mixtures. Based on the results, the herbage utilization by Korean native goats did not showed any significant difference between two mixtures, therefore there is a possibility that herbages of turf type mixtures can be used as a roughages by livestock.
