Summary: Using tissue, a series of pure cultures of Pleurotus pulmonarius was produced. Bracken sticks (Pteridium aquilinum) were inoculated and mushroom spawn produced on wheat grains. The spawn was sowed on proprerly prepared wheaten straw (substratum) and mushrooms were produced. After picking mushrooms, the remaining substratum was dried, ground and the rabbit food was prepared. The feeding experiment lasting 90 days was carried out on 4 groups of 15 rabbits. At the end of the experiment a complete hematological analysis of the Hyla rabbits was made. The feeding parameters were monitored. The rabbits from all 4 experimental groups normally consumed food and were progressing in their growth. At the end of the experiment the rabbits were slaughtered and the mear quality evaluated. The carcasses were cut into commercial parts and the organs of thoracal cavity and abdomen were analysed. The speed of glycogen decomposition in m.l.dorsi and leg mmuscles was also monitored. The basic chemical analysis of the meat was carried out; some technological properties of the meat examined and fatty ecids in the abdominal and scapular fat of the Hyle rabbits analysed.

Research goals: The need for food, especially that of animal origin, is growing every day. The struggle for profit is most frequently directed against man himself (his health and surroundings) because it is mostly contrary to the laws of nature. Man must use his wisdom to contribute to the quicker and more efficient course of nature. This research aims at proving that secondary agricultural products (straw and corn stalks) can be used economically in the closed circle of production cereals-mushrooms-meat, in which there is no waste or pollution of the environment. Saprophytic mushrooms grow on a dead organic substance and with their enzymic system they decompose the nearly indigestible cell wall of lignocellular substances. After the mushroom spawn grows through the above mentioned substances, the mushrooms are picked and the remaining substances (straw + mushroom spawn) are enriched with proteins, and the digestibility increases up to 70% and more. Since the quality of nutrition is one of the basic factors on which the meat quality depends, i.e. post mortal changes, it was necessary to carry out the feeding experiment with the Hyla rabbits. In that experiment it was necessary to monitor the growth, the food conversion and the state of health, as well as to examine the carcasses, organs, blood and meat quality.
