Opis: The effect of dietary fibre content on intestinal production of indolic compounds was studied in immunocastrated pigs (IC). In addition, entire males (EM) and IC were compared on control diet (with low fibre content). For the study 32 crossbred pigs were assigned, within a litter to 4 treatment groups; 24 pigs were immunocastrated (at the age of 77 and 112 days) and 8 pigs were kept as entire males (EM). IC were split into three groups (IC_H, IC_M and IC_L) fed three diets differing in crude fibre (34, 60 and 80 g/kg dry matter, respectively) and net energy (NE) (10.0, 9.3, 8.5 MJ NE/kg/DM, respectively). EM were fed high NE i.e. low fibre diet. The experiment started when pigs were 84 days old and finished at the age of 172 days, when pigs were sent to slaughter. Skatole and indole concentrations were determined in the samples of intestinal content taken from caecum (CE), ascending (AC) and descending colon (DC). The concentration of indole was the highest in CE and proximal part of the colon, while skatole concentration increased in the distal parts of the large intestine. Concentrations of indolic compounds did not differ between EM and IC that were fed the same diet. Lowering dietary NE by inclusion of high fibre ingredients reduced the production of indole in the intestinal content of IC pigs, whereas the production of skatole was not affected.

Vpliv vključevanja krmnih dodatkov z antioksidativnim potencialom na lastnosti kakovosti pršuta
Martina Dobaj, 2017, diplomsko delo/naloga

Opis: V poskusu smo preučevali vpliv naravnih krmnih dodatkov z antioksidativnim potencialom na nekatere lastnosti kakovosti pršuta. V raziskavo smo vključili stegna 24 prašičev, ki so v končnem obdobju pitanja v krmo dobivali različne dodatke. Kontrolna skupina (n=6) je dobivala standardno krmo, namenjeno pitanju prašičev, ostale tri skupine pa so v standardni krmni obrok dobivale različne dodatke: vitamin E (125 IE α-tokoferola, n=6), tanin (3 % komercialnega pripravka Farmatan, n=6) ali hmelj (0,4 % hmelja; n=6). Pred začetkom postopka predelave v pršut smo izmerili nekatere lastnosti surovine (stegen), na končnih izdelkih (pršutih) pa smo določili barvo (L*a*b* v mišicah biceps femoris-BF, semimembranosus-SM in semitendinosus-ST ter maščobnem tkivu), reološke lastnosti (s testoma TPA in SR v mišicah BF in SM) in kemijsko sestavo (vsebnost vode, maščob, beljakovin, soli, nebeljakovinskega dušika in indeks proteolize v mišicah BF in SM). Z izjemo dveh lastnosti v poskusu nismo ugotovili pomembnejših razlik v barvi, teksturi in kemijski sestavi pršuta med preučevanimi skupinami. Pri taninski skupini smo ugotovili nekoliko višje vrednosti L* in b* v mišici SM, pri krmljenju z dodatkom vitamina E pa smo zabeležili večjo vsebnost intramuskularne maščobe. Preučevani krmni dodatki z antioksidativnim potencialom v izbranih koncentracijah niso vplivali na lastnosti kakovosti pršuta.
