The severity of heat stress issues on dairy cows will increase as global warming progresses. Fortunately, major advances in environmental management, including fans, misters, sprinklers, and cooled waterbeds, can attenuate the effects of thermal stress on cow health, production, and reproduction. These cooling systems were, however, tested in subtropical areas and their efficiency in northern regions is uncertain.

The aim of this work was the presentation of an alternative method of determination of the total dry mass content in processed cheese. For the test purposes both reference method of determination of dry mass in processed cheese and moisture analyzer method were used. The tests were carried out for three different kinds of processed cheese. The moisture analyzer test required method validation, with regard to drying temperature range and mass of the analyzed sample. For Hochland cream processed cheese sample, the total dry mass content, obtained using the reference method, was

The water activity a w of a food is the ratio between the vapor pressure of the food itself, when in a completely undisturbed balance with the surrounding air media, and the vapor pressure of distilled water under identical conditions. A water activity of 0. The water activity increases with temperature. The moisture condition of a product can be measured as the equilibrium relative humidity ERH expressed in percentage or as the water activity expressed as a decimal. Most foods have a water activity above 0. The amount of available moisture can be reduced to a point which will inhibit the growth of the organisms. If the water activity of food is controlled to 0.

Environmental parameters to assessing of heat stress in dairy cattle—a review

Mickiewicza , Krakow, Poland. Considering the significant influence of high ambient temperature and heat waves on the well-being and productivity of dairy cows, it is to be expected that, in the course of the next few decades, climate conditions for raising cattle will deteriorate. Research has shown that heat stress causes many negative consequences in terms of physiological and behavioural disturbances and significant losses in milk production.

Production during weeks with relatively high THI values 70 or over was higher than production in weeks with lower temperature-humidity stress. In autumn and winter when THI values were low, the quantity and quality of pasture available was inadequate to sustain high levels of milk production. Short-term weekly responses of milk output to changes in temperature-humidity conditions above THI values of 70 were not consistent, either in terms of the direction or magnitude of production change. THI values may not have been high enough to adversely affect week-to-week production from predominantly Jersey herds, although some depression in lactation yields may have occurred.

Heat stress exerts a substantial effect on dairy production. The temperature and humidity index THI is widely used to assess heat stress in dairy operations. Herein, we review the effects of high temperature and humidity on body temperature, feed intake, milk production, follicle development, estrous behavior, and pregnancy in dairy cows. Analyses of the effects of THI on dairy production have shown that body temperature is an important physiological parameter in the evaluation of the health state of dairy cows. Although THI is an important environmental index and can help to infer the degree of heat stress, it does not reflect the physiological changes experienced by dairy cows undergoing heat stress.

 Вот именно, - простонал Джабба.  - Он над вами издевается. А вы тем временем погибаете.  - Он посмотрел на экран.  - Осталось девять минут.

Санта-Крус - самый старый район Севильи, где нет проездов между зданиями, лишь лабиринт узких ходов, восходящих еще к временам Древнего Рима. Протиснуться здесь могли в крайнем случае только пешеходы, проехал бы мопед. Беккер когда-то сам заблудился в его узких проходах. Набирая скорость на последнем отрезке Матеус-Гаго, он увидел впереди горой вздымающийся готический собор XI века. Рядом с собором на сто двадцать метров вверх, прямо в занимающуюся зарю, поднималась башня Гиральда.

 Именно так, черт возьми. Я был там, внизу. Резервное питание подает слишком мало фреона. - Спасибо за подсказку, - сказал Стратмор.

 Хочешь со мной переспать? - Теперь на Беккера смотрела юная девица, похожая на персонаж фильма ужасов Рассвет мертвецов. Темнота коридора перетекла в просторное цементное помещение, пропитанное запахом пота и алкоголя, и Беккеру открылась абсолютно сюрреалистическая картина: в глубокой пещере двигались, слившись в сплошную массу, сотни человеческих тел. Они наклонялись и распрямлялись, прижав руки к бокам, а их головы при этом раскачивались, как безжизненные шары, едва прикрепленные к негнущимся спинам. Какие-то безумцы ныряли со сцены в это людское море, и его волны швыряли их вперед и назад, как волейбольные мячи на пляже.

По-видимому, Танкадо считал, что два эти события чем-то различались между. Выражение лица Фонтейна не изменилось. Но надежда быстро улетучивалась.
