Abstract
The article provides data review of relevant publications, presenting issue of current state of the dairy cattle breeding in Western Europe and Mountain Altai. The intensification of milk production and milk quota abolition weaken milk from mountain farms with regard to direct competition with milk produced on the plains. The consequence is the declining number of mountain farms in the Alps that has negative influence on the ecological and economic situation. There are difficulties in promotion dairy products in the market despite the fact that dairy products are produced in the mountains from grazing cows and have an increased biological value in human nutrition. As a mountain region, Altai Republic has dairy cattle breeding that developed successfully throughout the XX century similar to Swiss concept. However, in recent years the industry is also in crisis due to the low animal productivity and the high costs of fodder production and purchase. The article describes some ways to increase economic efficiency of the industry in the region, considering foreign experience and local specifics.
Highlights
The main groups of biologically active substances contained in the bark of Betula pendula were determined by the spectrophotometric method
It was found that the place of growth affects the content
There is an increase in their content from the anthropogenic load
Summary
W – потеря в массе при высушивании сырья,%. Результаты по определению тритерпеновых сапонинов представлены в табл. 1. Таблица 1 Содержание тритерпеновых сапонинов в образцах бересты B. pendula в зависимости от места произрастания,%. Образцы: 1 – берёзовый лес, Чулымский район; 2 – берёзовый колок, г. Новосибирск; 4 – берёзовый лес, Искитимский район. Проведенные исследования показали, что место произрастания влияет на содержание тритерпеновых сапонинов. Содержание кумаринов в сырье определяли прямым спектрофотометрическим методом. X = D×V×100 % / K×m× (100 – W), где V – объем извлечения, полученного из сырья, мл; K – коэффициент пропорциональности, рассчитанный по калибровочному графику, построенному по стандартному веществу – кумарину (ГСО); D – оптическая плотность исследуемого раствора; m – масса сырья, г; W – потеря в массе при высушивании сырья,%. 2. Содержание кумаринов в образцах бересты B. pendula в зависимости от места произрастания,%
