Forage Productivity and Animal Performance on Different Grass/Legume Pastures for Grazing Management
Publication Date
1997
Description
A grazing trial was carried out to determine the effects of different grass/legume pastures on forage productivity, nutritive value, and animal performance. The pasture mixtures were mainly orchardgrass (OG)+ladino clover(T1), mainly OG+alfalfa(T2), mainly perennial ryegrass+alfalfa(T3), and grasses alone (mainly OG, T4). The pastures were rotationally grazed 7 times with growing heifers in 1991 and 1992. The proportion rate of ladino clover in T1 mixtures rapidly increased from 21% up 54 to 68% during the grazing season. However, the rate of alfalfa in T2 and T3 ranged between 12% and 23%. The annual dry matter yield ranged from 9.19 in T4 to 9.61MT/ha in T3. The contents of crude protein and calcium of forages were highest in T1(23.2%, 0.68%), lowest in T4(18.5%, 0.13%) The liveweight gain per ha was greatest in T1(1,073kg), lower in T2(810kg) and T3(784kg), and lowest in T4(643kg). In conclusion, pasture mixtures which included legume(clover) can increase forage nutritive value and animal performance.
