Rabbits were allotted to 5 groups in two trials: control, F-0.3 (added 0.3% of Famatan), TA-0.19 (added 0.19% of TA), TA-0.25 (added 0.25% of TA) and TA-0.5 (added 0.5% of TA). TA preparation is experimentally produced by Tanin Sevnica d.o.o. in extraction procedure of their commercial product Farmatan (water extract from sweet chestnut (Castanea sativa Mill.) wood), where only apart of tannins was bounded bz whey proteins. Statistical analysis was performed by SAS statistical package (SAS, 1999) with GLM procedure. The addition of 0.5% TA (TA-0.5) increased feed intake and weight gain during the most critical period (3 weeks after weaning) in comparison with Control group.The addition of 0.25% of TA (group TA-0.25) increased weight gain and live weight of rabbits during the entire trial in comparison with Control group. There were no differences between groups in feed intake and FCR during the entire trial. Rabbits from all groups with added TA (TA-0.19, TA-0.25 and TA-0.5) had significantly higher proportion of liver than Control rabbits. This can indicate higher burdening of liver where TA was added, but this influence has to be examined on greater number of experimental animals. The influence of added tannins (Farmatan or TA) on other slaughter parameters was not explicitMerili smo pitovne lastnosti 144 kuncev (104 samcev in 40 samic) slovenske očetovske linije SIKA od odstavitve (31. dan starosti) do zakola (73. dan). Kunce smo razdelili v 5 skupin v dveh poskusih: kontrolno, F-0,3 (dodatek 0,3 % Famatana), TA-0,19 (dodatek 0,19 % TA), TA-0,25 (dodatek 0,25 % TA) in TA-0,5 (dodatek 0,5 % TA). Pripravek TA poskusno proizvaja Tanin Sevnica d.o.o., kjer se je v postopku ekstrakcije njihovega komercialnega produkta Farmatan (vodni ekstrakt lesa navadnega kostanja (Castanea sativa Mill.)) del prisotnih taninov vezal na sirotkine beljakovine. Podatke smo obdelali s proceduro GLM v statističnem paketu SAS (SAS, 1999). Dodatek 0,5 % TA (TA-0,5)je povečal zauživanje krme in dnevni prirast v najbolj kritičnem obdobju prvih 3 tednov po odstavitvi v primerjavi s kontrolno skupino. Dodatek 0,25 % TA (skupina TA-0,25) je povečal priraste in telesno maso v celotnem poskusu v primerjavi s kontrolno skupino. V celotnem poskusu ni bilo razlik med skupinami v zauživanju in izkoriščanju krme. Kunci iz vseh skupin z dodanim TA (TA-0,19, TA-0,25 in TA-0,5) so imeli povečan dele jeter v primerjavi s kontrolno skupino, kar lahko kae na povečano obremenitev jeter, vendar bi to morali preveriti na večjem številu živali. Vpliv dodanih taninov (Farmatan ali TA) na druge klavne kazalnike ni bil jasno izraženTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
