Abstract:Cilj raziskave je bil ugotoviti vpliv dodatka tanina v krmni mešanici za prašiče na njihovo klavno kakovost in kakovost mesa. Poskus je bil izveden v letu 2011 na Univerzitetnem kmetijskem centru Pohorski dvor. V poskus je bilo vključenih 100 tekačev obeh spolov. Prašiči so bili razdeljeni v 5 skupin: kontrolna skupina in 4 poskusne, ki so poleg osnovne krme dobivale dodatek tanina: Farmatan (kostanjev ekstrakt, 2 g/kg krmne mešanice), Contan (hrastov ekstrakt, 2 g/kg krmne mešanice), Tanex (kombinacija kostanjevega in hrastovega ekstrakta, 0,5 in 1 g/kg krmne mešanice). V raziskavi smo spremljali različne lastnosti klavne kakovosti (masa toplih polovic, debelina mišice in slanine, površina mišice in slanine, masa stegna, mesnatost trupa in stegna), kakovosti mesa (pH, barva, sposobnost za vezavo vode) ter sestave mesa (vsebnost maščob, vode, beljakovin, delež metmioglobina). Naši rezultati so pokazali, da dodatki različnih vrst in koncentracij taninov v krmni mešanici nimajo vpliva na preučevane lastnosti pri prašičih, prav tako pa nismo zaznali škodljivega učinka. Za povzročitev zaznavnega vpliva so bile izbrane koncentracije taninov verjetno prenizke. Na podlagi dobljenih rezultatov ne moremo izključiti morebitnih koristnih oziroma škodljivih posledic uporabe večjih koncentracij tanina na klavno kakovost in kakovost mesa.

Title:Carcass and meat quality of pigs supplemented with tannins
Abstract:The aim of this study was to determine the effect of tannin supplementation on carcass and meat quality of pigs. The experiment was carried out at Pig Research Centre which belongs to the Faculty of Agriculture and Life Sciences (University of Maribor). The experiment comprised 100 pig fatteners of both sexes. The pigs were divided into 5 groups: control group and 4 experimental groups. Feed mixture of experimental groups was supplemented different preparations and concentrations of tannin: Farmatan (chestnut extract, 2g/kg feed), Contan (oak extract, 2g/kg feed), Tanex (a combination of chestnut and oak extract, 0.5 and 1g/kg feed). In the experiment, various carcass quality traits (warm carcass weight, muscle and fat thickness, muscle and fat area, ham weight, percentage of meat in carcass and hams), meat quality traits (pH, colour, water-holding capacity) and chemical components (fat, water and protein content, metmyoglobin percentage) were studied. Our results showed no effect of tannin supplementation on studied characteristics in pigs. However, no detrimental effect was observed. Tested tannin concentrations were probably too low to cause any detectable effect. Based on the obtained results, we cannot exclude the potential positive or negative effect of higher tannin concentrations on carcass and meat quality characteristics.
