The quality of bulky feeds on the farms of the Vologda Region
The article presents the results of studying the chemical composition and quality of forage harvested on farms of the Vologda Region. As a result of detailed analysis of roughages and succulents nutritive value it has been revealed that regarding metabolizable energy and crude protein they insufficiently meet the needs of highly productive animals. The proportion of the 1st and 2nd class fodders in 2014 was as follows: 14.1% of hay, 38.5% of haylage, 44. 8% of silage. The analysis of the received data on the nutrients content in roughages and succulent fodders allows to find the causes of their low quality and plan their elimination in the future.

Influence of feed quality on milk productivity indicators
The article presents the results of studies on affecting of feed quality on the quality and quantity milk indicators in view of a livestock management method and milking technology. The analysis has revealed the relationship between the balanced diet of dairy cows and the level of milk yield. With the improvement of bulky feed quality the quality of milk has improved too. During the period under review we have noticed an increase in milk production and mass fraction of milk fat content using all management methods and technologies of milking. The content of the mass fraction of protein in milk has stayed almost on the same level, only a slight decrease has been observed in the milking parlor. The results of the research have shown that the increase of harvested feed level and its nutritional value improves milk production.
