The paper presents the results of research on the assessment of the quality of fragmentation and the structure of totally complete feed rations in five different technologies (T1-T5) preparation and setting of TMR for cattle. The research was carried out in five farms in Wielkopolska, where dairy cows were kept. During the studies on farms TMR for dairy cows were prepared in the following portions:...
The paper presents current data on the area of organic farms all over the world and in Europe as well as factors influencing the development of this farming system. Among many factors affecting the development of organic production, issues related to the cultivation of varieties are very important in the economic, social and legal context, including methods of breeding allowed for organic farming,...
This article gives an overview of the use of X-ray absorption spectroscopy to characterize the magnetic properties for technologically important, low dimensional magnetic materials. An overview is given both for the experimental hardware, the measurements and the analysis of the spectra. The information obtained is discussed for metallic and semiconducting systems, using both the X-ray magnetic circular...
The aim of this study was to assess technical feasibility of servicing for modern agricultural tractors. Labour intensity of technical service during the entire servicing cycle was adopted as a measure of serviceability for agricultural tractors. Among tractors included in this study the lowest labour intensity of technical service (Pst= 25 h) was observed for Forterra 105 tractors by Zetor.
The studies were conducted in 2010-2012, at the Agricultural Experimental Station in Swadzim (52°26′20″N, 16°44′58″E), belonging to the Poznań University of Life Sciences, Poland. The response to sorghum intercropping of two maize varieties: Absolut (medium-early FAO 250) and medium-late Vitras (FAO 270) was evaluated, with reference to pure sowing as a control. Sorghum was represented by the medium-late...
The studies were conducted in the years 2010-2012, at the Agricultural Experimental Station in Swadzim (52°26′20″N, 16°44′58″E), belonging to the Poznań University of Life Sciences, Poland. The reaction of two cultivars of sorghum (GK Aron mid-early and late Sucrosorgo 506) the intercrop with corn, compared to pure sorghum seed was evaluated. Corn was represented by a variety of medium-late, with...
The paper presents results of research on comparison of operational and economical two technologies of preparation and feed distribution of total mixed ration (TMR) for cattle. The research was carried out in two farms in Wielkopolska where the doses in an amount from 1195 to 4900 kg were prepared at once. Average operating efficiency of tested fodder carriages were 4,71 and 8,12 t·h-1. Labor expenditures...
