Currently, it has been understudied which forms of feed supplements ensure the most positive effect on increasing milk nutritional value and processing properties. In this regard, an experiment was conducted on comparable groups of 90 cows. The animals of the 1st (control) group were fed compound feed concentrate that included the following ingredients: protected fat Megalac (3.1%); a buffering agent sodium bicarbonate (1.4%); protein digestion stimulator Farmatan TM (0.57%); mineral and vitamin premix Rindavit 51 ATG RV (3.6%). The animals of the 2nd (trial) group were given the following feed supplements: protected fat Nutracor (3.0%); a buffering agent Rumenbuffer (0.9%); protein-mineral-vitamin concentrate Cowfit 5 Plus (3.75%); mineral and vitamin premix Cowfit Immuno Fertil (0.75%). In the 2nd (trial) group, the levels of milk components increased as follows: lactose - by 20%; butterfat - by 15%; casein - by 25%; calcium - by 33%; phosphorus - by 53%; copper by 45%, zinc - by 89%; vitamin A - by 67%; vitamin E - by 30%; that was indicative of milk nutritional value increase.

Тенденции развития науки и образования При анализе морфологических параметров сосны корейской под пологом леса, нами было отмечено, что большая часть культур характеризуется слабым охвоением со светло-зелѐной окраской, не ярко выраженной мутовчатостью и рыхлой кроной. Установлено, что рост в высоту и по диаметру в данном фитоценозе ниже в 1,7 и 2,3, соответственно, чем при коридорном способе реконструкции. Лучшим ростом и развитием отличаются культуры, заложенные коридорным способом, поскольку проведенные лесоводственные уходы способствовали уменьшению сильной конкуренции со стороны древесно-кустарниковой растительности. Средняя высота культур на момент исследования была 7,15 м, диаметры стволов на высоте 1,3 м-11,3 см, диаметр кроны-3,15 м.

The studies were conducted in 2015 on Large Whitepigs of the breeding farm of the AO “Linevskiy plemzavod” (Altai Region, Smolenskiy District). The research goal was to determine the growth rate and blood biochemical indices of pigs when using LipoKar feed supplement.According to the design of the experiment, the animals of the control group were fed the basic dietonly. In the trial group, the sows received LipoKar feed supplement for 20 days startingfrom the 85th day of pregnancy. Then, the piglets born from them were also fed LipoKar feed supplement during the nursery period for 40 days in a 10 days’ interval. The dosages of the feed supplement were as following: for pregnant sows -2.1 g perhead per day; for young animals -0.8 g per head per day. The following effects of using LipoKar feed supplementwere found in the trial group: increasing piglet live weight from 4.2% to 11.7% (p < 0.001), average daily live weight gains -from 3.4% to 18.6% (p < 0.05); total protein, vitamin A and alkaline re-servein blood serum by 15.5% (p < 0.001), 9.2% (p < 0.05) and 20.9% (p < 0.001), respectively

Most blood parasitoses are transmitted by means of carriers - ticks or insects, which bodies undergo certain development stages or transmission is carried out mechanically. Dirofilariasis is a zoonotic disease of animals and humans carried by mosquitoes. The reasons for dirofilariasis spread are the unrestricted movement of animals from one region to another. To diagnose dirofilariasis, a microscopy method of a fresh blood drop was used. Diagnosis for babesiosis in animals was made based on clinical traits and results of microscopic examination of peripheral blood smears stained according to Romanovsky-Gimza. The study of the ixodic ticks’ prevalence as distribution sources of dog babesiosis was carried out in Barnaul in different parts of the city. The spring rise of babesiosis begins in late April and ends at the end of May, the summer period June-July is characterized by a low incidence rate. The autumn rise is from August to October, i.e., it coincides with ticks’ activity during this period. The incidence of ticks in Barnaul is not uniform. The largest range of ticks’ distribution is found in the highland part of the city.
