The quality of five silage maize hybrids grown in 2020 at five different locations in Serbia (two in northern province of Vojvodina (Srem) and three in Central Serbia) was tested in 2021 in the laboratory of the Department of Food Technology and Biochemistry of the Maize Research Institute “Zemun Polje“. The dry matter content, lignocellulose fiber content and in vitro dry matter digestibility (IVDMD) of of the whole plant maize hybrids: ZP 707, ZP 7357, ZP 790, ZP 8701 and ZP 873 were investigated. The 7001 hybrid was used as a standard. The avarage dry matter content varied between 37.77±1.88% (ZP 790) and 42.64±7.19% (ZP 707), while in vitro dry matter digestibility ranged from 58.77±1.96% (ZP 8701) to 63.77±2.09% (ZP 707).The share, as well as the type of the plant cell wall components - lignocellulosic fibers, determines the nutritional quality of silage maize as animal feed. The NDF content ranged from As the NDF content increases with maize maturity, animals show a tendency for lower silage intake. However, although in some cases NDF can be considered a negative indicator of silage quality, NDF is a necessary component of ruminant nutrition. Based on the achieved results, it can be concluded that hybrids ZP 707 and ZP 7357 proved to be the best silage maize forms.
