Projekat:
Odabrane biološke opasnosti za bezbednost/kvalitet hrane animalnog porekla i kontrolne mere od farme do potrošača (MPNTR - 31034)

Ključne reči: TČS meso; mlečne pege; svinje; klanica
Sažetak
Cilj istraživanja bio je da se utvrdi uticaj prisustva mlečnih pega na hematološke parametre, kvalitet trupa i mesa svinja. Ispitivanja su obavljena na 120 svinja, starosti šest meseci, žive mase oko 115 kg. Prisustvo mlečnih pega na jetri svinja je ocenjivano na liniji klanja na osnovu Welfare Quality® (2009) protokola. Pored toga, analizirana je i kompletna krvna slika. U cilju utvrđivanja kvaliteta trupa, analizirani su sledeći parametri: živa masa, masa toplog i hladnog trupa, randman, debljina leđne slanine i mesnatost. Od parametara kvaliteta mesa određivani su pH vrednost i temperatura 45 minuta post-mortem. Meso svinja je razvrstavano u klase kvaliteta (bledo meko vodenasto-BMV; meso normalnog kvaliteta; tamno, čvrsto i suvo meso-TČS) na osnovu pH vrednosti merene 45 minuta post-mortem (Adzitey i Nurul, 2011). Analizom hematoloških parametara utvrđeno je da su svinje sa mlečnim pegama na jetri imale statistički značajno veće vrednosti monocita, eozinofila, bazofila i neutrofila, dok su vrednosti za broj eritrocita, koncentraciju hemoglobina, hematokrit i MCV bile statistički značajno niže u odnosu na svinje bez promena na jetri. Svinje sa mlečnim pegama na jetri imale su statistički značajno nižu živu masu, masu toplog i hladnog trupa, randman i mesnatost u odnosu na svinje bez mlečnih pega na jetri. Ista grupa svinja je imala statistički značajno višu pH vrednost kao i učestalost pojave TČS mesa. Stoga se može zaključiti da ispitivanje prisustva mlečnih pega na jetri na liniji klanja može da bude značajan pokazatelj ne samo dobrobiti svinja na farmi, već i kvaliteta trupa i mesa svinja.
