摘要: Abstract Studies at the University of Reading (UK) compared silage quality, feed intake and digestibility maize with maize–sunflower (MS), maize–kale (MK) maize–runner bean (MRB) silage, when sunflowers, kale runner beans represented 26, 7 16% total dry matter (DM). All intercrop silages had higher crude protein values (MS, 137 g kg −1 , MRB, 120 g kg MK, 105 g kg ) than (81 g kg ). The neutral detergent fibre (NDF) acid (ADF) contents were cellulase gamminase (NCGD) lower for MRB MS silage. fermented well pH ranging from 3.9 to 4.2 ammonia-N content less 100 g kg total nitrogen (TN). An in vivo study sheep showed no significant difference voluntary between four silages, highest lowest 68 62 g DM (kg BW 0.75 per day being recorded MK DM (DMD) organic (OMD) intermediate inclusion all three intercrops significantly increased metabolisable energy both substantially those
