| Abstract: | This study evaluated the effect of simple covering of silo on the quality and nutritional value of whole-plant corn silage in summer.The silage samples were taken from 10,20,40,80,160 and 320 cm under the top surface of aboveground silo and analysed for their quality,nutritional composition and in vitro DM digestibility.The results showed that the whole-plant corn silage from 0 to 40 cm under the surface of the silo contained the higher population of fungi and lactobacilli,the higher content of NDF,ADF and ... |
| Keywords: | silo whole-plant corn silage nutritional values |
