state of cows, and therefore the technological process
in a dairy farm.
2. Increasing the content of "effective" fiber in the fodder mixture by 5.8-7.0%
due to the cut off of the slisher of the cutter feeder-shredder-mixer feed leads to
increased chewing activity of cows by 2.7-6.2 %, but does not conducive augmentation
yields.
3. The quantitative growth of "effective" fiber in the fodder mixture causes
increased cow motor activity is influenced by the degree of grinding of roughage that,
along with the change in the content of effective fiber, violates the way of consumption
of feed (life) by cows and induces them to more active displacements in search of the
usual feed mixture.
4. The productive effect of the feed mixture within the efficiency of the slasher
depends not so much on the degree of grinding of roughage, but on the stability of the
use of mechanisms. The periodic change in the use of a slasher negatively affects the
lactic productivity of dairy cows.
5. The degree of grinding of feed in the feed mixture has a significant impact not
only on the chewing activity of cows, but also on the course of metabolic processes in
their body. Thus, high blood levels of test cows alanine aminotransferase can be
considered as one of the evidence of increased stress on the organism of cows, and
above all – on the liver.
