The paper deals with the degree of development of interest in arts in young people, and the justifiability of the current tendency of revision and abbreviation of the art curricula in schools. The research is focused on the structure of interests in various artistic disciplines in secondary school students, and the aim is to determine whether the degree of students? interest depends on the school type, gender and previous experience. The research was conducted on the sample of 555 students from 111 schools, who filled out the questionnaire during one school period. The data were processed by multifactor analysis of variance. There was a higher degree of interest in video and performing arts, which are not present enough in students? surroundings. The girls showed a higher degree of interest in all disciplines, as well as grammar school students compared to their peers from vocational schools. It was shown that the higher the number of programmes attended, the higher the interest in all forms of art. Young people who were completely inactive showed interest in video arts, which serves as an important guideline in the process of moving and socialising them. The results confirm that youth?s interests and needs are discrepant with what is offered to them. It is necessary to introduce various artistic contents as parts of the curriculum, which would make school an integral part of their life, the part that directly influences the development of creativity and increases responsible participation in the society.

Temperatures of the northern wall, ceiling and floor of a 2 &times; 12 milking house as well as of a waiting area in front of the milking house were measured for 24 hours a&nbsp;day in the winter season with an average external daily temperature of &ndash;8.6&deg;C. The influence of low external temperatures on the temperatures of cows&rsquo; mammary glands was measured with a&nbsp;non-contact thermometer RAYNGER ST 6 equipped with laser. The analysis showed that the low external temperatures and insufficiently warmed external walls [average 24-hour temperatures: (t<sub>st</sub>&nbsp;=&nbsp;+1.32&deg;C), ceiling (t<sub>s</sub> = +2.65&deg;C), floor (t<sub>p</sub> = +3.29&deg;C)] as well as the waiting area in front of the milking house (t<sub>d</sub>&nbsp;= +1.9&deg;C) produced unsuitable temperature conditions despite of the use of heaters in the milking house, resulting in the undercooling of mammary glands and the traumatising of dairy cows. The temperatures of mammary glands of tested dairy cows were evaluated by a multifactor analysis of variance. The time and place of measuring were statistically significant on the significance level 0.05. The F -test value for the factor of time was 12.342, with probability 0.0007. The F -test value for the place of temperature measuring was 1061.979, probability 0.0000. Among the equations of curves of the dependences of teat end temperature on the milking time, the closest seemed to be the logarithmic function with determination index R<sup>2</sup> = 0.7404. &nbsp;
