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.
Comparative evaluation of alfalfa silage and alfalfa silage with legumes and cereals
The article presents the results of the comparative evaluation of alfalfa silage and alfalfa silage with other legumes and cereals. The high protein content in silos is 14.45-14.73%. The fiber content is 31.07-33.04%. It contributes to easy digestion and does not require additional processing.
Vologdskiy functional feed for farm animals
Сomplexity and high price of making and using the preparation as well as its insufficient functional properties are the disadvantages of well-known functional feeds farm animals. For example, as a rule, yeast supplements for farm animals have a high cost, since relatively expensive raw materials (cake, after-alcohol bard, bran, etc.) are used for their production. The article is devoted to the development of an experimental production technology for a functional feed for farm animals named Vologdskiy and, in particular, to the study of the chemical composition of the functional feed product.
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.
