    The aim of the authors was to evaluate changes in the longissimus muscle area (LMA) and rump fat thickness (P8) based on real-time ultrasound scanning in the Hungarian Simmental cattle breed. Ultrasonic measurements were carried out on the same 11 Hungarian Simmental fattening bulls by Falco 100 (Pie Medical) equipment (I.: age: 357±23.47 days, live weight: 475.55±51.40 kg; II.: age: 418±23.47 days, live weight: 555.10±54.11 kg) on two occasions. Animals were kept in small groups, on deep litter, and fed on silage and concentrate. LMA and P8 were measured on the scans, between the 12th and 13th ribs by manual outlining. Results for the investigated traits during the examinations were as follows: P8: I.: 0.373±0.154 cm, II.: 0.624±0.161 cm; LMA: I.: 65.72±5.89 cm2, II.: 71.74±8.94 cm2. During the fattening period, P8 increased significantly (I-II.: t=3.73, P<0.001). A significant positive correlation was calculated between results of measurements I. and II. in the case of LMA (r=0.71, P<0.05). Results imply the possibility of selling bulls with smaller LMA earlier, at lower body weight. Application of ultrasonic measurements in fattening technology could generate a more quality-related pricing system.

    traditi ons in each region. In addition, nowadays the infl uence of the so called invasive species is also decisive. The eff orts to protect the farming environment and the range of products have renewed those needs that return to the past traditi ons. Some examples of animal races and species are living their renaissance: jersey and hoary catt le, “coloured” pigs (black and white belted pigs, Cornwall, Berkshire) There are getti ng also importance some parti ally forgott en sheep, goat, Hungarian hen, Hungarian giant rabbit and other species. The process is widened with the products manufactured from the menti oned animal species and the marketi ng: rural tourism, events, meeti ngs and rural development. This way, the special quality regional artisan products will enhance the development of a region; will sati sfy the export necessities, and enrich the product scale with diff erent “regional tastes”.
