Effect of fibrous fodder addition to rations on production results of fattening pigs

, : Effect of fibrous fodder addition to rations on production results of fattening pigs. Roczniki Nauk Rolniczych Seria B Zootechniczna 106(1-2): 39-49

The respective experiments were carried out in 4 groups (by 16 heads in the group) of pigs of Polish Large White breed fattened from 30 to 110 kg. The nutritive traits of the PT-1 and PT-2 Standard feed mixtures with added meal of the whole dried maize plants were estimated. The maize meal addition resulted in a growth of the fiber content from 4.7 in the control diet up to 8.20, 10.70 and 11.85% in rations of the experimental groups. The growth of the ration mass and of the fibre content did not exceed any unfavorable effect on production results, of the fattened pigs. Even a tendency to higher weight gains and better feed conversion in fattened pigs given the ration with the maize meal addition was observed. Daily body weight gains amounted to 601-613 g in experimental groups in relation to 547 g in the control group. In an initial fattening phase the maize meal addition led to a digestibility decrease of all nutrient components, nevertheless in the final fattening phase even somewhat higher protein, fiber and fat digestibility was found. An addition of maize meal did not cause any significant changes in the slaughter value of pigs.
