Abstract
The aim of this research was to determine the influence of dietary supplementation of natural zeolite Anivital-SPS on growth and development potentials, food conversion, slaughtering traits and health status of pigs. The research was carried out on three-way crossbred fattening pigs, having Large White (LW) and German Landrace (GL) in the dam line and Pietrain (P) in the terminal sire line. Pigs were divided into three groups, which were given diets of different composition. The ST1 diets fed to P1 group contained 3% of Anivital-SPS, while the pigs of P2 group had diets with added 3% of Anivital-SPS and 1.4% of fat. The ST2 diets fed to pigs of P1 group contained 6% of Anivital-SPS, and pigs of the P2 group had diets supplemented with 6% of Anivital-SPS and 3% of fat. During the fattening period, pigs were weighed and data on weights were used in calculating average daily and total gains during fattening. At the end of the first fattening phase (45th day), the P1 and P2 groups were highly significantly heavier (P<0.001) than the control group. At the end of fattening, there were no statistically significant differences (P>0.05) among groups. Average daily gains also differed significantly (P<0.001) at the end of the first fattening phase, however, for the whole fattening period, statistical significance was P=0.03. Compared with the control group, food conversion into kg of gain was better by 8.02% and 4.94% in the P1 and P2 group, respectively. Supplementation of Anivital-SPS to diets did not have any effects (P>0.05) on quality traits of pig carcass.
