Effect of feeding haylage harvested with a biological preservative on rumen digestion of cows

The study carried out a comparative study of the feeding of haylage preserved in a traditional way without the use of a preservative and prepared with a biological preservative Bioamid-3. A significant increase in volatile fatty acids was found at 18.33 mmol / l and the number of infusorians was 91.67 thousand / ml. The total microbial number of cicatricial fluid in the cows of the experimental group was 1.7 x 10 6 cfu / ml above the control group. The level of acetic acid in the control group increased by 3%.
