In the experiment carried out on 72 fatteners divided into 4 groups, the nutritive value of full ration mixtures of PT1 f PT2 type was evaluated. In the mixtures studied, a part or the whole amount of soybean meal was replaced fay commercial rapeseed meal or the one from new varieties of rape of twozero type. The supplement of rape meal of zero-zero type rape improved body gain and feed consumption in the first period of fattening by 4-10% and by 3-4% /P>0,05/ in the whole fattening period. Tylosin added to the mixtures containing the improved rape meal had better stimulating effect than Zn-bacitracin. The type of rape meal did not influence significantly the slaughter indices and meat quality. Commercial rape meal supplement in the mixtures resulted in the increase in thyroid weight of the animals /P<0,01/. It has been concluded that rapeseed meal from zerozero varieties can replace soybean meal in fatteners fed concentrates.
