Energy consumption analysis was carried out in two ways of haymaking with in field drying hay on eleven family farms at different locations in Slovenia. Energy consumption of haymaking is determined from used mineral diesel fuel when performing various working operations with the tractor aggregate in one complete haymaking process (mowing, spreading, tedding, side raking, hay collection with self-loading wagon or collecting hay and baling with round baler). Total energy consumption for all working operations provides us with data on final energy consumption for haymaking in two different ways (hay collection with self-loading wagon or collecting hay and hay baling with round baler). The average total energy consumption (from mowing to hay baling) per hectare area (MJ/ha) during hay making with hay baling in round bales is higher by 27.6 % than the average total energy consumption (MJ/ha) in hay making, when hay is loaded with a self-loaded wagon (energy from mowing to loading hay with self-loaded wagon). In hay transport, average hourly energy consumption (MJ/h) used to transport round bales is 24.1 % higher than hourly energy consumption for hay transport with self-loaded wagon. The average hourly energy consumption (MJ/h) for manipulation with round bales is 6.5 % higher, compared with the working operation of unloading of self-loading wagon and the transport of hay from a self-loading wagon with the hay blower in the hay storage.

Within the experimental fields of the Infrastructure Center Jablje two ecotypes of cocksfoot (Dactylis glomerata L.) and tall fescue (Festuca arundinacea Schreb) were seeded in individual plots. The objective of the study was to evaluate the nutritional value of both species at relatively late first cut. Samples were collected at four different dates of first cutting: 22.5., 2.6., 12.6., and 24.6. The chemical composition and net energy value for lactation (NEL) were determined using near infrared reflectance spectroscopy (NIRS). At comparable harvesting dates the crude protein content (CP) and net energy for lactation (NEL) were higher in tall fescue, while the crude fiber content (CF) was higher in cocksfoot. During the observed period, the CP content decreased more rapidly in tall fescue (-1.09 vs. -0.74 g CP per kg of dry matter per day), while the NEL content decreased more rapidly in cocksfoot (-0.029 vs. -0.022 MJ NEL per kg of dry matter per day). Significant differences in the decline of nutritional value between the two plant species were observed. It was also found out that at comparable date of the late first cut, tall fescue has a higher nutritional value than cocksfoot
