Summary

The research works on bulky feeds quality were conducted on the farms of the

Vologda Region. Bulky feeds were, on average, of the 3rd quality class and of inferior

quality. The proportion of the 1st and 2nd class silage is 44.8%. It is due to the fact

that many producers started active application of various preservatives and began

using modern means of mechanizing the production process. Studying bulky feeds

on nutrient substances for the given period revealed that in preparing trench feeds

58.6% of inferior feeds (silage and haylage) and 37.5% of the 1st class feed had

been made. It is because of the fact that farms try to improve the keeping conditions

of bulky feeds through the complex preparation of trenches for making fodders. The

silage made in the first half of June has the highest quality, its dry matter contains, on

average, 13.49% crude protein, 10.24MJ of metabolic energy, and 0.67 feeding units.

The protein content of silage ranges from 11.41% to 11.95%, its metabolic energy

varies from 8.74 to 11.87MJ. Haylage made in the second half of June, in early July,

and aftermath of legume-cereal grasses rate the second. The amount of protein in dry

matter of these feeds ranges from 12.62% to 12.25%; metabolic energy varies from

9.12 to 9.78MJ. The later the first mowing is, the lower the nutrient content of the

feed is. It should be noted that the carotene content in trench feeds is low. Only early

haylage contains sufficient amount of carotene (34.14 mg/kg). Rational organization,

volumes and quality of bulky feeds production affect the prospects of modernizing and

intensifying livestock production of the region.
