NEW APPROACHES IN DOMESTIC FORAGE PRODUCTION AND THEIR IMPACT ON CATTLE PRODUCTIVITY

The purpose of research is to study the influence of domestic plant components in the form of dry pumpkin and carrots in diets on the productivity and physiological state of cattle. Objectives: to study the effect of dried carrots and pumpkin in diets on milk production, milk quality, reproductive function and the physiological state of Holstein cows. The study was conducted in the Belgorod Region in the agricultural production complex Collective Farm named after Gorin. The object of the study is lactating Holstein cows after calving. 2 groups of animals were selected: 1st control and 2nd experimental (dairy cows after calving) of 10 animals each. The control group was fed diets accepted on the farm, and the experimental group was additionally given dry carrot and pumpkin concentrate in dosages approved by the standards (for dairy cows in the amount of 60 g per head per day for 90 days). During the study, the animals were examined and their physiological condition was monitored. An increase in the average daily milk yield of cows in the experimental group was observed – 32.8 ± 1.11 kg versus 30.2 ± 1.22 kg in the control, or by 8.6 % compared to the control; increase in milk fat content by 7.5 %; increase in the vitamin composition of milk with vitamins A, B, C, K; improvement of reproductive function (the onset of the first heat 5 days earlier, a decrease in the insemination index). Based on the results obtained, we recommend using dried carrot and pumpkin concentrate in the diets of lactating cows.
