The effect of dietary supplementation with dried fruit and vegetable pomaces on production parameters and meat quality in fattening pigs

The presence of biologically active substances in feed mixture is discussed to have beneficial effect on animals' health and products. The purpose of the study was to determine the effect of dietary supplementation with dried apple, chokeberry, black currant, strawberry and carrot pomaces on production parameters and meat quality in fattening pigs. The use of dried pomaces of chokeberry showed tendencies for increased feed intake and reduced fattening period. The dried pomaces had no impact on saturated and monounsaturated fatty acids profile in meat, however in some groups an elevated level of polyunsaturated fatty acids from n-3 family and a decline in total cholesterol level was observed (P ≤ 0.05). The highest oxidative stability and vitamin E content was found after supplementation with black currant (P ≤ 0.05). Summarizing, the used dried pomaces improved several parameters related to meat quality, what might positively influence consumers' health.
