By assessing the results of sifting of manufactured feed mixtures (Table 3), it can
be argued that the inclusion on the technological capacity of a slasher led to a
significant reduction of the specific content of "effective" fiber in the feed mixture.
At the same time, the amount of fractions in the three upper sites decreased by
2.7-6.2 %. Conversely, shutting off the slasher during the loading of the components
of the diet when cooking the forage mixture, provided an increase in the proportion of
"effective" fiber in the diet.
It should be noted that the set of feed used on the farm, and their qualitative indices
provided high content in the feed mixture of small components that accumulate in the
pallet. Even when the slasher was turned off, 28-30 % of the dietary components were
- 46 -
