The system of full-value feeding of the cattle in the Vologda region: effects on milk productivity and milk quality

The aim of the work was to study the system of full-value feeding of the cattle and impacts of the system on milk productivity and quality of the milk produced. The samples of feeds from all the districts of the region are sent to the chemical laboratory of the North-West Scientific Research Institute of Milk and Pastures. The largest part of the feeds belongs to the I-II class and was made in 2017. The feeds contain high level of raw protein from 11,1 to13,1 %. The fiber content is in the permitted size in the range of 22,1 to 31,4 g. Special attention should be paid to the sugar level in the silage because it effects digestion and transformations of protein and fiber and activates micro ora of the paunch. The composition of the feeds studied was characterized by high quantities of such macro-elements as potassium and sodium and microelements - copper and cobalt. The conclusion can be made that for full-value feeding of cows it is necessary to prepare feeds with balanced levels of sugar, protein and fiber and necessary quantities of potassium and sodium. The nature and climate factors support high nutritive values of the feeds made in the Vologda region.
