Effect of the degree of forage shredding on the chewing activity of cows
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 102, Issue
Abstract
The material of studies on the effect of grinding (shredding) roughage on the level of chewing activity of dairy cows is presented. Round-the-clock monitoring of the chewing process using an electronic system based on HR-Tag ™ transponders is an effective tool for controlling the physiological state of cows, as well as the technological process on a dairy farm. It is proved that an increase in the size of coarse fodder particles leads to an increase in the chewing activity of cows by 2.7-6.2%. An increase in the content of effective fiber in the feed mixture causes higher motor activity in cows less due to the degree of fodder grinding fineness than to the fact of changes in the structure of the diet itself. It violates the way of feed consumption by cows (their way of life), and induces their more active search of the usual feed mixture. The productive effect of the feed mixture within the efficiency of a slasher depends not so much on the degree of filtration of fibrous fibers, but on the stability of the use of mechanisms. The periodic change in the use of a slasher has a negative effect on the lactic productivity of dairy cows.
