Abstract

The purpose of this experiment was to investigate herbage production and nutritive value of C. ternatea harvested at 60, 75 and 90 days after planting. The legume was planted in eighteen of 3 × 3 m2 plots a t 40 × 20 cm2. Forage was harvested at 60, 75 and 90 days after planting as treatmens. Variables measured included forage production, nutrient content and in vitro dry matter and organic matter digestibility. Herbage production was not significantly different (P>0.05) when harvested at different stages of growth. Leaf : stem ratio, however, declined (P<0.05) with advancing growth stage. Forage quality in terms of crude protein content was comparable (P>0.05) among different harvest time. Meanwhile the energetic value as shown by in vitro organic matter digestibility (IVOMD) was significantly higher (P<0.05) when C. ternatea was harvested 60 days compared to 75 and 90 days after planting. It can be concluded that for calf supplement, C. ternatea is preferably harvested at 60 d after planting. Key words : Clitoria ternatea, IVOMD, energy, calf supplement

种植后60、75和90天采收阴蒂的饲料产量和营养价值

本试验的目的是研究种植后60、75和90天收获的三叶草的牧草产量和营养价值。豆科植物种植在18块3 × 3 m2到40 × 20 cm2的地块上。分别在播种后60、75和90天采草。测量的变量包括饲料产量、营养成分含量、体外干物质和有机物消化率。不同生育期收获的牧草产量差异不显著(P>0.05)。叶茎比在不同采收期呈下降趋势(P0.05)。体外有机物消化率(IVOMD)所显示的能值，采后60 d显著高于采后75 d和90 d (P<0.05)。综上所述，犊牛补饲时，以播种后60 d采收为宜。关键词:阴蒂;IVOMD;能量
