It was found that the lowest percentage of cows with mastitis was recorded in winter: 10.3% (P≤0.001) when milking with ‘De Laval’ equipment and 17.7% (P≤0.001) when milking with the ADM-8A unit. The highest incidence of mastitis in cows was observed in summer: 21.0% (P≤0.001) and 27.1% (P≤0.001), respectively, when milking cows at milking parlors ‘De Laval’ and ADM-8A. It was found that, when using milking equipment ADM-8A, adult cows are 2.1-1.7 times more prone to mastitis compared to cows of the 1st and 2nd calving. When milking cows with the ‘De Laval’ unit, the incidence of mastitis in adult cows is 4.3-1.1 times higher than in cows of the 1st and 2nd calving. Gentle milking mode on the ‘De Laval’ equipment allowed to increase the number of completely healthy animals to 74%, which is 9.6% more than when using the milking unit ADM-8A (64.4%), and to reduce the incidence of clinical mastitis in cows by 3.4 times. It has been established that in cows with disorders in the udder the content of somatic cells in the secretion of the udder significantly changes (with a high degree of correlation) in all periods of the functional state of the body. Thus, during subclinical mastitis r=l0.72 (P≤0.001) and udder irritation r=l0.58 (P≤0.05). At the beginning of lactation, subclinical mastitis is accompanied with significant changes in the activity of enzymes: muramidase r=l0.84 (P≤0.001), lactoperoxidase r=l0.65 (P≤0.01) and lactoferrin r=l0.66 (P≤0.01).

The article deals with the advantages of using certain digital technologies when learning English for specific purposes. The article is devoted to the problem of information and communication technologies, describes their positive impact during English language classes for specific purposes, and provides some effective digital tools that their students can also use in their work and study, such as Skype, a word processor, e-mail, virtual conference platforms, simulation software, mobile technology and the Internet as a source of authentic material and communication.Additionally, the author examines the potential possibilities of using such a digital tool as Skype, which refers to free software in its basic version, and lists 14 advantages of using information and communication technologies in the process of learning English for specific purposes according to the researcher Butler-Pascoe.The implementation of digital technologies in language education is one of the promising directions of informatization of the educational process, which allows users to gain access to authentic material.Modern information and communication technologies contribute to the active, creative mastery of new material by students, contribute to its presentation at a new, qualitatively higher level. In the organization of the educational process, their integration opens fundamentally new opportunities.The Skype tool is used in various forms for formal and informal language learning. Searching the Skype community platform shows the number of existing language courses, chat groups or conversation clubs.In addition, digital technologies can also provide effective support to the teacher when there is a lack of experience in various aspects of the subject and their use opens up fundamentally new opportunities in the organization of the learning process.

Abstract. The article deals with environmental school projects. Many teachers already know they want to use environmental education techniques and concepts. The best way to attain it is to engage students in projectbased learning. Nowadays there are many terms to describe the environmental project in class. Sometimes they are rather confusing. Special attention is paid to Ukrainian schools where such projects can be implemented. It is obvious there are Pros and Cons of this technique. In this paper we try to concentrate on the Ukrainian example. We also may see distinctions and similarities of it in comparison with the rest of the countries which accumulated substantial experience in this field. There is a lot of information to consider before choosing this method. Indeed, project learning has proven especially fruitful in environmental education. Without a doubt, students shouldn`t wait passively for the educators to spoon feed them every step of the way and take responsibility for their own learning process. For this reason, fostering student-to-student interaction and enhancing their self-esteem should be included into the design of environmental classes.

The article deals with the benefits of using the language portfolio as an integration of digital technologies in the English language assessment.The research is devoted to the use of digital technologies, describes the structure of the language portfolio and analyzes the positive aspects of e-portfolio.Prior to the transition to a more communicative approach in language learning, formal language exams were very narrow, which could not take into account all communicative skills. Teachers are trying to evaluate a wider range of communicative skills with the help of the new portfolio in order to make the current process more relevant, as well as to involve students in self-improvement and reflection on their own learning.Though many teachers do not try to integrate digital technology into their assessment system, the language portfolio is one of the most modern means of providing assessment based on modern experience in the field of language learning.The author explores the potential use of an e-portfolio that can be quickly distributed and even adapted. But most teachers have never used an e-portfolio or have only begun to incorporate some of its elements into their teaching and learning. The use of an electronic portfolio contains a number of advantages, among which we would like to highlight the opportunity for the younger generation to gather a large amount of evidence of their communicative competence and provide a comprehensive assessment of the student’s language skills. In the portfolio students include videos, audio recordings, examples of mind maps, wiki entries, examples of articles read, tests on the Internet, etc., which can be found in the central repository.
