Sažetak
Investigation was conducted on 150 swines devided into three groups. The first group was control treatment (without antibiotic), second and the third group had rations with 30/15 PPM and 50/25 PPM of Salinomycin-Na respectively. All groups received ratio with 16.5% of raw protein and 13.42 MJ/kg ME from live mass of 28 kg up to live weight of 60 kg. After they reached mass of 61 kg up to the end of production ratio was balanced at level of 14.2% of raw protein and 13.27 MJ/kg ME. The objective of this investigation was to determine the influence of Salinomycin-Na on farm revenues. Salinomycin-Na applied in higher conentration (50/25 PPM) has changed distribution of commercial classes in comparison to control group. The number of animals in E and U classes increased and the number of animals in R class decreased. Changes in the group with lower concentration (30/15 PPM) were marginal. The application of Salinomycin-Na increased farm revenue for 2.89% for lower and 8.90% for higher concentration. That is due to the changes of two factors, higher final weight and higher leanness of the carcasses. In addition to that, marginal increase in unit price of fodder for experimental treatments and better conversion caused fodder costs increase of 1.41% for lower concentration and 3.32% for higher concentration. The use of Salinomycin-Na in form of Grosal and concentration of 50/25 PPM was proved as economically viable. It is possible to get an increase in gross margin after feed costs of 5%. Even lower rate of Salinomycin-Na (30/15 PPM) increased gross margine after feed costs, but only for 1.5%.
