Sažetak
To examine the possibilities of maize substitution as an energetic nutrient with by-products obtained by manufacturing tomatoes, peppers and grapes in the nutrition of different categories of swine on the production results and health condition an experiment was carried out in the nutrition of weaned piglets. The researches were conducted in the producing conditions at pigs farm ZZ “Edinstvo” in the village of Chelopek near the town of Tetovo, R. Macedonia where experiments were organized in a group controlled system. The experiment was carried out on piglets after weaning in a period of 28-30 days with an average body weight of 8.66–8.84 kg. For the experiment were used mongrels of Swedish and Dutch races with equalized genetical potential were each group in experiment consist of equal number of males and females. The experiment piglets was carried out on 72 weaned piglets divided into 3 groups, each group having 12 piglets of different sex. The experiment lasted for 42 days in 2 phases with 21 days each phase. In the experiment 2 mixtures were used for weaned piglets from 1 to 21 days and the whole mixture for piglets in breeding in a period of 21–42 days of the experiment. The experimental piglets from the control group were fed mixture without a share by the examined by-products, whereas the experimental groups were fed with mixture substitution of maize with different quality of the above mentioned by-products. The mixture contained – 3% i.e.6% from the examined by-products. Maize’s semisubstitution with by-products obtained by manufacturing tomatoes, peppers and grapes especially in the amount of 3% did not have any negative effects on the production results of weaned piglets. In general, the applied treatments did not have negative effect on the production results and health condition of different categories of swine which real possibilities for maize’s semisubstitution with by-products obtained by manufacturing offers tomatoes, peppers and grapes.
