Abstract
For ruminants, the basis of the diet is voluminous feed, in the dry matter of which structural carbohydrates
occupy a significant place. Despite the fact that ruminants have a complex system adapted
to the digestion of fiber, the latter is far from completely absorbed in the digestive tract of animals.
Established, that the highest percentage of NDF and lignin was contained in the straw and
amounted to 81,4 and 24,2 %, respectively. Hay showed a lower content of these feed elements. Our
results are consistent with the data of other authors where the amount of NDF and lignin in cereal
hay was 67,0 and 9,3 %, and the amount of hemicellulose and cellulose was 26,7 and 31,4 %. In
other feeds of Pobeda LLP, the content of NDF is as follows: in silage – 25,0 %, in haylage – 62,0 %.
This quality of feed was obtained largely due to the observance of the terms of grass mowing, that is,
from the quality of the initial plant material. As the research results showed, the silage harvested
on the farm contains an average of 36 % dry matter. Corn silage harvested on the farm contains an
average of 61,0 % NDF and 30,5 % ADF, which is consistent with the data of other authors, where
the content of NDF in corn silage is 54,6 % and 34,3 % ADF of dry matter. The data are confirmed
by studies of scientists, where NDF in corn silage was 59,2 % and 31,3 % ADF, as well as scientists,
in the works of which, the number of NDF, ADF and lignin was 58,9; 32,9 and 5,4 %.
