20.500.12556/RUL-59880 MHS status and salivary cortisol concentration in individually housed pigs MHS-status in koncentracija kortizola v slini pri individualno uhlevljenih prašičih Salivary cortisol was evaluated as stress measure in pigs of two malignant hyperthermia (MH) genotypes (NN and Nn), housed individually in metabolic cages and in comfortable large pens with straw. Three replicates were done, each including 8 German Landrace barrows, four (2 NN, 2 Nn) housed in pens and four (2 NN, 2 Nn) in metabolic cages. Altogether there were 24 animals included in the experiment. Saliva samples of all animals were collected simultaneously every 15 minutes between 8.00 and 11.00 a.m. on days 8, 22 and 36 of the experiment. Pigs in more stressful conditions (metabolic cages) had higher salivary cortisol values than pigs in pens, indicating that salivary cortisol might be a suitable indicator of stress in pigs. Higher salivary cortisol values in NN- in comparison to Nn- pigs indicated stronger response to stressful conditions in NN-genotype. Kortizol v slini je bil ovrednoten kot pokazatelj stresa pri prašičih dveh MH - genotipov (NN in Nn) v dveh individualnih uhlevitvah (metabolne kletke in prostorni boksi z nastilom). V vsaki od treh ponovitev je bilo 8 kastratov pasme nemška landrace. Štiri živali (2 NN, 2 Nn) so bile uhlevljene v bokse, štiri (2 NN, 2 Nn) pa v metabolne kletke. Skupno je bilo v raziskavo vključenih 24 živali. Vzorci sline so bili odvzeti istočasno od vseh živali, vsakih 15 minut med 8. in 11. uro, in sicer 8., 22. in 36. dan poskusa. Živali v bolj stresnem okolju (metabolne kletke) so imele višjo koncentracijo kortizola v slini kot živali v boksih, kar nakazuje, da je kortizol v slini primeren pokazatelj stresa pri prašičih. Višje koncentracije kortizola pri živalih NN - genotipa v primerjavi z genotipom Nn kažejo na močnejši odziv na stresne razmere pri genotipu NN. pigs animal physiology endocrinology malignant hyperthermia saliva plasma cortisol prašiči fiziologija živali endokrinologija maligna hipertermija slina plazma kortizol true false false Biotehniška fakulteta Angleški jezik Slovenski jezik Delo ni kategorizirano 2015-07-10 18:34:01 2015-07-10 18:34:01 2022-07-05 03:42:11 0000-00-00 00:00:00 2006 0 0 Str. 29-36 št. 1 Letn. 88 2006 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 636.4:591.1 1581-9175 1968520 213840640 http://www.dlib.si/details/URN:NBN:SI:doc-A85GLMTP 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=59891 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
