Assessment of biochemical blood status of highly productive cows kept under different confinement conditions
The research has been carried out with the project named as «Study of feeding of highly productive cows under different confinement systems with the account of their biochemical status and milk quality in the European North of the Russian Federation». Regular biochemical blood tests make it possible to respond, to classify and to take measures for eliminating the adverse impact in a timely way. The article describes the results of biochemical blood tests of highly productive cows in tie-up and freestall housing in different periods of their physiological cycle. The research has been conducted on an agricultural farm in the Vologda region. The reference values and the obtained indicators of biochemical parameters of animal blood have shown disorders of energy, protein, mineral and vitamin metabolism in highly productive dairy cows.

Оценка биохимического статуса крови высокопродуктивных коров при разных способах содержания
Исследования проводились в рамках проекта: «Изучить систему кормления высокопродуктивных коров с учетом биохимического статуса животного при разных способах содержания в условиях Европейского Севера Российской Федерации». Регулярно используя биохимические исследованиями крови, можно на ранних стадиях неблагоприятного влияния своевременно отреагировать, классифицировать и принять меры к устранению негативного воздействия. Представлены результаты биохимических исследований крови высокопродуктивных коров в разные периоды физиологического цикла, на привязном и беспривязном содержании, проведенные на базе сельскохозяйственного предприятия Вологодской области. В конечном итоге, используя референсные значения и полученные показатели биохимических параметров крови животных, можно сделать вывод о том, что у высокопродуктивных молочных коров отмечаются нарушения энергетического, белкового, минерального и витаминного обменов.

Evaluating harvested feed in the Vologda Region for the presence of nitrate compounds
The improvement of agriculture is inextricably linked with the increase in feed production. The intensive feed production system involves using high doses of nitrogen fertilizers. This significantly increases the yield, but at the same time nitrates accumulate in soil, water and feed. Excessive amount of nitrates causes the wrong course of functioning in natural ecosystems and animal organisms, there is a decrease in the biological value of products. Meanwhile, the importance of nitrates and their impact on human health has increased recently. However, this problem has not yet lost its significance and is increasingly attracting attention of many researchers of various specialties. Currently, there is no clear agreement on the permissible amounts of nitrates in feed for farm animals and on the effect of these toxicants on metabolism.

Monitoring the viability of dairy cows
The article presents a working model for monitoring the basic body processes in animals. The main approaches to the implementation of the proposed model are described and disclosed. It has been indicated that the requirements for assessing feed quality and actual nutritional value include the task core to be solved not only in order to control viability, but also to increase the dairy farming efficiency at agricultural enterprises of the Vologda region. More than 5 types of feed samples, more than 50 biological material samples (blood of dairy cows), 30 samples of cicatricial content have been studied during the experiment. The results of feed analysis are the basis of the method and the starting point for the implementation of the tasks. The presented parameters of the biological test are used to assess the level of metabolic processes in the dairy cows body, to predict further productivity, reproductive qualities and to prevent the health of animals. The methods combination is the full-valued feeding of dairy cows. The importance of control in the normalized feeding system is not only in monitoring the productive herd, but also allows to control the dairy activity of cows. The future researches are connected with improving the control system of dairy cows viability that to be detailed in the direction of the ruminants digestion.

Quality of the green mass of grass at farms of the Vologda region
The article outlines the regulatory requirements for assessing the quality of green fodder and the actual nutritional value of green mass at farms of the Vologda region. More than 100 green mass samples were investigated for the period 2016 - 2018. The results of the analysis showed a decrease in feed: dry matter from 24.46 to 22.92 g / kg, digestible protein by 1.36 g / kg and crude fiber from 21.22 to 20.74 g / kg, as well as an increase in nutritional value by indicators: raw protein from 16.14 to 16.27%, exchange energy from 11.19 to 11.26 MJ, sugar from 9.04 to 13.87% and carotene from 175.43 to 176.35 mg / kg. Analysis of the quality of the grass mass shows a great dependence of nutritional value on the prevailing climatic conditions in different years. Cereals and legumes in the Vologda region show a fairly high nutritional value of green mass under favorable climatic conditions, compliance with the technology of harvesting bulk feed, taking into account regulatory requirements for quality assessment. This affects the final assessment of the harvested feed. Research in this area should be deepened and carried out using highly productive agrophytocenosis of promising forage crops. Since green mass underlies the laying of high-quality silage, knowledge of its chemical composition and nutritional value is of paramount importance.
Biochemical blood test in high-yielding lactating cows during the initial stage of lactation depending on the housing system
The biochemical parameters of blood in high-yielding lactating dairy cows during the initial stage of lactation and the tightness of this stage depending on the housing system have been studied. Innovative cattle housing and milking methods are considered in comparison with the classic tied housing system. The authors point out that the basis of effective dairy farming is the organization of standardized feeding system, and its impact on the condition of the animal.
