The increase of probability and depth of weather anomalies, which is important characteristic of climate change process, leads to higher risk of loss of perennial grasses forage yield, rise of price volatility on forage grain market. Increase of sustainability of dairy production supposes development of adapted to new weather conditions technologies of forage production, which are characterized by different investment and current costs. It generates a need of economic evaluation and comparative analysis of technologies taking into account climate change forecast and need of sustainable forage production guarantee. Purpose of the research project is the development of approaches to assessing adaptive technologies in forage production, increasing of dairy farming sustainability to changes in the external environment, including climate change. We assessed changes in forage production technologies in the Leningrad region of Russia, analyzed the implications of these changes for production and financial performance of dairy farming, proposed and tested methods for determination of the optimum harvesting time of perennial grasses. Special attention is paid to the long-term effects of changing the structure of cows＇ diet--shortening the productive use of animals, which reduces the efficiency of dairy herd use and limits the possibility of expanded reproduction. The primary method of the study is the analysis of milk production statistics in the Leningrad region and the Russian Federation. As a result of the study, the necessity to improve the production and investment planning quality, as well as the use of forecasts during planning of dairy production, is grounded. 相似文献

由于甜菜糖的低价格以及制糖甜菜播种面积的减少,2013年俄罗斯甜菜制糖的产量或将降至400万吨。2012年俄罗斯制糖甜菜的播种面积为110万公顷。根据俄罗斯糖业协会的预测,2013年俄罗斯制糖甜菜的播种面积将减少20%,降至90万公顷,与2009年的播种面积持平。 相似文献

引起非洲猪瘟的病原是非洲猪瘟病毒(african swine fever virus,ASFV)。ASFV是一种有囊膜的DNA病毒,是非洲猪瘟病毒(Asfarviridae)科,非洲猪瘟病毒(Asfivirus)属的成员。病毒具有高度的基因以及抗原变异性。ASFV的自然宿主是生活在非洲的野猪,但不同品系以及日龄的家猪也对ASFV高度易感。病毒也可以感染各种Ornithodoros属的软蜱,且可以在软蜱体内存活5年以上。 相似文献
