20.500.12556/DKUM-69604 Vpliv dodajanja tanina, hmelja, in vitamina e v krmo na rastnost in klavno kakovost prašičev Effect of supplementing pigs with tannin, hops and vitamin e on growth performance and caracass quality Cilj raziskave je bil preveriti vpliv tanina, hmelja in vitamina E na rastnost in klavno kakovost prašičev. Pitovni poskus smo izvedli v obdobju od decembra 2014 do februarja 2015 na komercialnih prašičih križancih. V poskus je bilo vključenih 41 živali obeh spolov, ki so ob začetku poskusa v povprečju tehtale 75,1 ± 10,4 kg. Po doseženi masi 80–90 kg so bile živali krmljene s krmilom BEK 2, ki mu je bilo pri poskusni skupini T1 dodanega 3 % komercialnega pripravka Farmatan, pri skupini T2 0,4 % hmelja in pri skupini T3 vitamina E (125 IE α-tokoferola). Prašiči so bili med poskusom tehtani trikrat, po zakolu pa je bila stehtana še masa toplih polovic. Prašičem smo izmerili debelino slanine in mišice (m. glutaeus medius) ter izračunali delež mesa v trupu po metodi DM5. Z analizo podatkov smo ugotovili, da tanin, hmelj in vitamin E niso imeli statistično značilnega vpliva na rastnost in klavno kakovost prašičev. Statistično značilni razliki (P>0,05) smo ugotovili samo kot posledico vpliva spola pri prvem in pri drugem tehtanju, pri čemer so imele svinjke v povprečju od 11,1% (P= 0,0030) do 13,7 % (P= 0,0081) manjšo telesno maso od kastratov. The aim of the study was to find out the effect of supplemented tannin, hops and vitamin E in pigs diet on the growth and carcass quality of pigs. A fattening experiment was conducted in the period from December 2014 to February 2015. A total of 41 animals of both sexes were studied. At the beginning of the test, they weighed on average 75.1 ± 10.4 kg. After reaching the weight of 80-90 kg, the animals were fed with the BEK 2, and pigs were divided in the groups T1 (3% of the Farmatan), T2 (0.4% of hops) and in the T3 group vitamin E (125 IE α-tocopherol). During the study, the pigs were weighed three times. At slaughter, the warm weight of slaughtering halves was recorded. Muscle (m. glutaeus medius) and fat thickness were estimated, and carcass meat percentage was calculated according to the DM5 method. Data analysis showed no statistically significant effect of tannin, hops and vitamin E on the growth performance and carcass quality of pigs. Statistically significant differences (P>0,05) were found only as a effect of sex at the first and at the second weighing, where gilts had on average 11,1% (P = 0.0030) to 13,7% (P = 0.0081) lower weight in comparison to barrows. antioksidanti prašiči krmni dodatki rastnost klavna kakovost antioxidants pigs nutrition growth carcass quality true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2018-02-07 09:42:59 2018-02-26 10:45:46 2022-08-01 17:39:49 2019-07-11 17:37:57 2018 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:JA16JLLY MAG_Kokol_Jernej_2018.pdf MAG_Kokol_Jernej_2018.pdf 1 B3638C241159F2B109FF84C9578204DD fc7046908090753249e455d780a63ff4b55ac74b9fabec262b5d68e4e611bcb5 afab693e-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/420e71db-2326-42bb-9add-543518076a53 https://dk.um.si/Dokument.php?lang=slv&id=122238 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
