The influence of biologically active supplement from spreading quinoa, rowan and lecithin on ketone bodies level and milk productivity of Holshtine cows with subclinical ketosis

The aim of the study was to investigate the effect of phytocomposition of spreading quinoa, common rowan and lecithin on the level of ketone bodies and milk productivity of Holstein cows with subclinical ketosis. The experiment was conducted at the Streletskaya experimental station of the Federal scientific center of legumes and groat crops in the Orel Region. The objects of the study were newly calved Holstein cows of the 2nd lactation. To correct the disorders caused by subclinical ketosis, the developed biologically active phytoadditive was tested, including spreading uinoa (100 g), common rowan (70 g) and lecithin (10 g) per 100 kg of live weight of the animal for 30 days in addition to the main treatment. The obtained data allow us to state that the use of the proposed phytoadditive has a positive effect on the bodies of the Holstein cows with subclinical ketosis, which is confirmed by the normalization of the level of ketone bodies and an increase in the average daily milk yield. By the 30th day of the experiment, there is no reliable difference in the value of the ketone body indicator in cows with subclinical ketosis receiving the phytoadditive (Group 2) and healthy animals (control), although in sick cows of the first group receiving only the basic treatment of the farm, the level of ketone bodies remains high (higher than in healthy ones by 3.35 mg / % in serum, by 8.07 mg % in urine, by 2.75 mg % in milk). The average daily milk yield of cows taking the biologically active phytoadditive (Group 2) increased on average by 3.4 kg/head by the 30th day of the experiment, while for cows in the first group (the main treatment of the farm) the increase was only 1.2 kg per head.
