The development of new feed productsbased on natural local raw materials, allowing to balance the rations of cowsfor energy and protein, essential fatty acids and mineral elements is topical.Practical interest at the present stage in the feeding of highly productivecows is the use of flax and rapeseed oil seeds, which are sources of energy,high-grade protein and polyunsaturated fatty acids. Scientific and economicexperience was conducted in educational and experimental farm FSBEI HEIzhevsk SAA on cows of black and motley breed selected by the method ofpair-analogues (three groups). The animals of the control group received thebasic ration, the analogues of the first test group were replaced by 30 % ofthe crude protein of the sunflower meal cake with flax seeds (for protein), theanimals of the second test group for rapeseed. The introduction of flax seedcontributes to an increase in the mass fraction of fat in milk by 0.06 % (P ≥ 0,95),rapeseed seeds stimulate an increase in the mass fraction of protein. The milkof the first-calf cows that received rapeseed seeds was characterized by alarge 0.16 and 0.25 % dry skimmed milk residue content compared to the controlgroup analogs (P ≥ 0.95) and the first test group (P ≥ 0.99), lactose on 0.2 %(Р ≥ 0.999) incomparison with milk of the peers of the first test group. The mass fraction of protein in the milkof cows in the experimental groups was 2.93 and 2.97 %, which is higher compared to the milk of analogues from the control groupby 0.1 and 0.14 %, respectively (P ≥ 0.999). The use of fodder additive based on flaxseedand rapeseed oilseeds has prospects in feeding cows as a relatively cheapsource of protein and polyunsaturated fatty acids and a factor improving thephysic-chemical properties of milk.
