Modern pig production needs new tools for fast, reliable, more effective breeding. In the present paper we present a chip containing 45 SNP (Single Nucleotide Polymorphisms) which enables the determining of 1 genetic disease (PSS – Porcine Stress Syndrome), 4 QTLs genes: PRKAG3, CAST, MC4R and ESR, which together with the remaining SNPs create a panel useful in marker-assisted selection and veterinary control. The SNPs were genotyped using the PCR-APEX (Arrayed Primer Extension) technique. Special attention is paid to evaluation of the 45 SNP chip as an alternative approach to parentage and identity control. Based on allele frequency estimations, for a sample of 88 individuals of commercial pig lines, the probabilities that a randomly chosen candidate parent would be excluded from paternity or maternity were estimated to be 99.9% when genotypes of both parents and a progeny were known, and 98% when the genotypes of only one parent and a piglet were available. The marker set presented here also reached a probability of identity in the order of 10-16, which allows for unequivocal discrimination of animals or their products among billions of individuals. Further improvements for upcoming chip versions were also considered.

The study was aimed on determining the clinical protective value of Lydium-KLP and Methisoprinol in the prevention of respiratory system diseases, as well as their effect on the health status of pigs in large-scale commercial breeding and on the improvement of in the effectiveness of specific immunoprophylaxis of mycoplasmal pneumonia of in swine (MPS). Piglets at the age of 7 d were divided into eight groups of 25-30 piglets each. On days 7 and 21 of life they were immunised with Respisure vaccine (group I) or administrated Lydium-KLP or Methisoprinol (groups IV and VII). In other groups, Lydium-KLP or Methisoprinol were given simultaneously (groups II and V) or 48 h before immunisation with Respisure (groups III and VI). Control piglets were administrated PBS (group C). Clinical observations as well as post-slaughter and animal husbandry analyses indicated that the simultaneous administration of Lydium-KLP or Methisoprinol with Respisure gives better results in comparison to immunisation- only with Respisure. The statistically-significant differences were found in the mean percentage of meatiness between groups receiving Methisoprinol with or 48 h before Respisure and control group, as well as in the point evaluation of lesions in the lungs between groups receiving Lydium-KLP with Respisure and Methisoprinol 48 h before Respisure and control group. The study demonstrated the beneficial effect of coupled administration of Lydium-KLP or Methisoprinol and Respisure on the improvement of health status and the productive performance of pigs, as well as on the effectiveness of specific immunoprophylaxis of MPS in large- scale commercial breeding. The most beneficial variants of coupled administration were the simultaneous application of Lydium- KLP and Respisure, and Methisoprinol application 48 h before immunisation with Respisure.
