Examining the efficiency of the semi substitution of the maize with a by-products obtained by manufacturing vegetables and fruits in mixtures for growing and fattening pigs

To examine the possibilities of the maize’s substitution as an energetic nutrient with by-products obtained by manufacturing tomatoes, peppers and grapes in the nutrition of swine on the production results and health condition where are carried out experiment in the nutrition of growing and fattening pigs. The researches are conducted in the producing conditions at pigs farm ZZ "Edinstvo" in the village of Chelopek near by the town of Tetovo, Republic of Macedonia, where are organized experiment in a group controlled system. The experiment is carried out on growing and fattening pigs in a period of about 60 days with an average body weight of 27.00+0.64 - 27.69+0.71 kg. For the experiment used mongrels of Swedish and Dutch races with equalized genetical potential. Each group in experiment consist of equal number of males and females. The experiment of the growing and fattening pigs is carried out on 48 pigs divided into 3 groups with each group having 8 pigs of different sex. The experiment lasted for 100 days in 2 phases with 50 days each phase. In the experiment are used 2 mixtures for growing and fattening pigs from 1 - 50 days and the whole mixture for fattening pigs in a period of 50 - 100 days of the experiment. The experimental pigs from the control group from experiment are fed with mixture without a share from the examined byproducts, whereas the sample groups were fed with food with substitution of the maize with different qualities of the above mentioned by-products. In the pig’s feeding mixture - 6% i.e.9% from the examined by-products. Maize’s semisubstitution with a by-products obtained by manufacturing tomatoes, peppers and grapes especially in the amount of 6% does not have any negative effects in the production results on a growing and fattening pigs. In overall, the applied treatments do not have negative influence in the production results and health condition of swine which enables real possibilities for maize’s semisubstitution with a by-products obtained by manufacturing tomatoes, peppers and grapes.
