Abstract
The possibility of utilization of dried distillers' grains with solubles (DDGS) in animal feed was investigated. Samples of maize hybrids ZP 548 and ZP 655b, and DDGS obtained from hybrids ZP 548 and ZP 548c were used as components of the feed. The total protein content ranged from 12.42% to 31.18%, moisture from 5.49% to 9.55, and ash content from 1.85% to 4.37%. The contents of NDF, ADF, ADL, hemicellulose and cellulose fibers ranged from: 13.90% to 48.13%; 2.9% to 20.69%; 0.27% to 2.44%; 10.69% to 30.17%, 2.62% to 18.32%, respectively. In vitro, dry matter digestibility ranged from 55.20% to 89.76%. It was concluded that the samples of DDG obtained from red and yellow maize hybrids kernel are very suitable as components for the preparation of animal feed.

Summary
Cultivated on around one million hectares annually, maize (Zea mays L.) represents the most important field crop in the Republic of Serbia. Serbia produces around 8 million metric tons yearly and takes 16th place in world maize production. According to the United States Department of Agriculture (USDA), the total estimated 2021 world maize production was 1.13 billion metric tons (World Agricultural Production.com, 2021). The total world bioethanol production has reached 109.9 billion liters in 2019 with the United States as the largest bioethanol producer, this industry has suffered some setbacks during the past two years due to the COVID-19 pandemic (Nikolić et al, 2020; RFA, 2020). Dry distillers’ grains with solubles (DDGS) are a valuable and affordable by-product of the bioethanol industry available in large quantities that can be used as a replacement for traditional feedstuff (Lei et al, 2017; Semenčenko et al, 2014). During the bioethanol production process, a total of 229 kg of DDGS with
