20.500.12556/DKUM-91328 Growth performance, meat quality, and fecal microbial population in limousin bulls supplemented with hydrolyzable tannins The objective of this study was to investigate the effects of supplementation of hydrolyzable tannins (HT) from sweet chestnut wood extract (Castanea sativa Mill.) to the diet of Limousin bulls on growth rate, carcass and meat quality traits, and fecal Clostridia strain levels in a 7-month feeding trial. Thirty-two bulls were randomly assigned to four treatment groups (CON (without addition of HT); TAN 1 (1 g HT kg−1 DM); TAN 2 (1.5 g HT kg−1 DM); and TAN 3 (1.5 g HT kg−1 DM with a nominally lower dose of concentrate). Compared with the CON group, supplementation with HT significantly (p < 0.050) increased bull growth rate during 4–7 months, whereas carcass and meat quality traits were unaffected during the last three months of fattening. Supplementation of HT significantly reduced meat drip loss (p = 0.000) compared with the CON group. No effects were observed on the total number of fecal Clostridia strains; however, the concentration of Clostridium perfringens was significantly lower (p = 0.004) in TAN 1 than that in the CON group. The results obtained in fattening bulls indicate that the addition of HT is justified in practice to improve growth performance and feed efficiency without adverse effects on the carcass and meat quality. carcass characteristic chestnut tannins fecal Clostridia growth performance Limousin bulls meat quality lastnosti trupa kostanjevi tanini uspešnost rasti biki pasme limuzin kakovost mesa true false true MDPI Angleški jezik Slovenski jezik Znanstveno delo 2024-12-12 15:34:46 2024-12-12 15:47:43 2024-12-13 03:10:22 0000-00-00 00:00:00 2022 0 0 Str. 1-16 št. 7, št. članka 939 Letn. 12 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-02-19 2022-06-24 2022-06-28 636.2.087 116379139 10.3390/agriculture12070939 2077-0472 Mergdus_2022_Growth_Performance.pdf Mergdus_2022_Growth_Performance.pdf 1 FA453BD9B2384CAB0BF28DF40542436A eb6f2f07bedd6a3a2376131c4ac3f9031cb0778d1faa880ced16bd55e65620de dd7c668e-b897-11ef-b21d-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=187303 https://doi.org/10.3390/agriculture12070939 0 3c3a5918-b896-11ef-b21d-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=187302 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
