  The economic value of grassland products is not always clear. In addition to demonstrating the social benefits of grassland products, the objective of the present study is to present the value of their diverse forms of utilization and their definitions in practice. This study groups marketable and non-marketable grass products and introduces a new category, the animal husbandry value of grasses. Among other factors, economists differ from researchers in other areas of science, as they are basically motivated by three issues The first question economists always raise is: “What can it be used for?”, the second is: “What is it worth?”, and the third is: “How can it (its value) be determined?” Any answers to any further questions are subordinated to the answers to these three.

  High yielder cows optimal feeding is always a major question in farm management. We attempted to find the optimal yield- and weight group in a Holstein_Freisian herd. Handled more than 2000 milk record samples and concluded that the optimal body weight is about 600-650 kg. Also step up from medium yielder to high yielder is more cost efficient than pushing the milk production over 30 kg milk daily. Our results show that fitness traits and body scores are major factors and every 50 kg of extra weight rises the forage cost in average of 0,11 €cents. The mid-weight cows produce 25 kg of milk daily but the herds are very heterogeneous. The solution should be smaller cows, homogeneous herds and optimized feeding.
