Nutritive value of barley and wheat whole crop silages at different stages of maturity for dairy cows 1. communication chemical composition digestibilities and energy contents



Wirtschaftseigene Futter 35(2): 171-186



Winter barley (WB) and winter wheat (WW)-whole crop silages (WCS) were harvested at different stages of maturity of middle to end of milky stage (WCS 1), before beginning of doughy stage (WCS 2) and middle of doughly stage (WCS 3). The dry matter (DM) contents of the silages were for WB and WW, respectively, 28.8% and 33.5% (stage 1), 36.6 and 37.0% (stage 2) and 48.1 and 43.5% (stage 3). During maturity grain ears increased from about 41% of the DM (stage 1) to nearly 60% of the DM (stage 3). The yields of grain from barley and wheat were 55 dt and 57 dt per ha. While the crude protein differed little (9 to 11%) in silage DM, the crude fibre content fell from 30% of DM of stage 1 to about 26% of the DM of stages 2 and 3. In contrast, the starch content increased from nearly 10% of the DM (WCS 1) to about 20% of the DM (WCS 2 and 3). Sugars only contributed 1 to 4% of the DM of the silages, irrespective of the content in the fresh material. All silages at each stage of maturity were of high quality because of a short chop length, good consolidation and the use of lactobacterial additive. The digestibility of the organic matter was not significantly influenced by the stage of maturity, but the measurements with cattle tended to be lower in the latter maturity stage. The reasons for this are a lower digestibility of the crude fibre (WW, stage 3) and of starch (WB, stage 3). Sheep digested the organic matter of WB at an average of 69.5% and of WW at an average 65.5%, whilst for cattle these values were 66.5% (WB) and 60.1%(WW). Therefore, net energy values were calculated using digestibilities found for cattle 5.7 MJ NEL per kg DM (WB 1), 5.5 (WB 2) and 5.3 (WB 3), 5.0 MJ NEL per kg DM (WW 1 and 2) and 4.7 (WW 3), respectively. Using the digestibility values obtained with sheep the net energy values were on average approximately 0.4 MJ NEL per kg DM higher. But at stage 1 the measurements for cattle and sheep were very similar.
