Three groups of crossbreeds of wbp x pbz breeds (10 fattening pigs in each group) were fed Starter (30-70 kg) and Finisher (71-105 kg of body weight) all-mash which contained triticale meal, barley and different kinds of protein feeds. Fattening pigs of the control group (K) were given mixtures with extracted soybean meal, W groups - mixtures with rapeseed cake and fodder pea. Meat-bone meal was introduced into all Starter mixtures. It was proved that independently of whether the mixtures contained extracted soybean meal or rapeseed cake with pea, similar and high body gains (778 and 783 g) of swines were obtained. The introduction of 25% of rapeseed cake instead of soybean meal significantly decreased the body weight gain (709 g), and simultaneously the most beneficial effect on post-slaughter indices was found. Moreover, a decrease in fatness and an increase in the number of polyunsaturated fatty acids in muscles were proved, and the proportion of PUFA n-6/n-3 amounted to 10:1 instead of 16:1 in the control group. The application of rapeseed cake with pea resulted in an increase in meat content (53.1% instead of 51.2% in K group) and in the improvement of meat palatability.
