Abstract

The effect of aqueous extract of pine needles, pine nut shells and arabinogalactan on the metabolism of dairy cows was studied. The objectives of the research were to investigate the elemental composition of aqueous extract of pine needles, pine nut shells and arabinogalactan and to study the effect of cows’ feeding on aqueous extract containing these supplements on the biochemical parameters of blood, physical and biochemical parameters of cows’ urine. The experiment was carried out in theKrasnoyarskTerritoryon black-and-white cows at the age of fi calving with an average body condition and life weight of 580-600 kg. Two groups of cows were formed, 10 animals in each. The duration of the experiment was 100 days. The cows were kept tied, in year-round stalls, milking was carried out automatically into the milk pipe. According to the scheme of the experiment, the control group was fed on the main diet, the experimental group was given aqueous extract (200 ml/head/day) of pine needles (15 g/l), pine nut shells (25 g/l) and arabinogalactan (25 g/l) in addition to the main diet. The test infusion was fed in a mixture with concentrated feed. The feeding ration corresponded to the zootechnical standards. It was found that feeding cows on aqueous extract of the studied forest components did not have a negative eff on the metabolism in the body of the animals: the biochemical parameters of blood and the physicochemical parameters of cows’ urine corresponded to the norm of healthy animals. At the same time, metabolic processes in the blood of the cows in the experimental group were very intensive, mineral and carbohydrate metabolism improved, as evidenced by an increase in glucose content by 16.6%, iron – by 17.8, phosphorus – by 13.0%.
