The potential of grass hay on milk production of dairy cows
Profitability of milk production depends on quantity, quality and price of voluminous feed. Cost of feed represents about 50% of the total price of milk. Therefore, it is important to have information about adaptability and stability species that are intended to be used in the production of forage in an area, in order to increase food production and significantly reduce its share in the cost of milk. The aim of this study was to compare and determine the productive potential of several grass species in semi-humid region of Southeast Europe. The study used five species of grass with a few materials per species. The yield and quality of hay were analyzed through two years of production. The study showed no statistically significant differences between varieties within species. Significant differences were found between species for yield and other investigated traits. Italian ryegrass varieties were achieved the highest yield of hay, while the largest proportion of crude protein has been realized with cocksfoot grass species. All kinds of ryegrass had higher relative feed quality in relation to the species of grasses. The realized values of yield and quality of all the analyzed grass species were onsiderably lower than expected. The orchard grass species had the highest protein yield what enables the production of 12264 kg milk per ha. The highest net energetically production (NEl) had ryegrasses with a potential of 21265 kg of milk /ha.
