Effect of hawthorn as a feed additive on milk yield and quality of cow's milk

In the course of the study, the fruits of the Caucasian hawthorn ( Crataegus caucasica K. Koch) were added to the feed of the Holstein Friesian and Caucasian Brown (including 5 heads) dairy cattle as a feed additive, where feeding was carried out over a period of one month (20.03.2022-20.04.2022) and there was an increase in the quantity and quality of milk every 10 days. So, in contrast to conventional feeding, when feeding with hawthorn fruits, a noticeable increase in the specific gravity of milk, fat and lactose in dry matter, as well as the amount of macro- and trace elements, was recorded. It was also determined that the increase in milk was about 12.5%.
