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 Clostridiumperfringens 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.

The study aims to identify any changes in the communication channels used by Slovenian livestock farmers before and during the COVID-19 pandemic, as well as the main (dis)advantages of relying on them. An online survey was completed by 502 Slovenian farmers of various farm enterprises in winter 2020/2021. Most respondents generally used telephone, e-mail, and the internet to obtain agricultural information before and during the COVID-19 pandemic. During the pandemic, farmers increasingly relied on online conferences and social networking sites. At the same time, younger farmers and farmers with a higher education level used digital channels the most frequently, with men doing so more often than women. Digital channels were primarily used by cattle and horse farmers, while cattle farmers showed the greatest online conference participation. Respondents reported having more time to spend with their families and animals as an advantage and the lack of face-to-face interaction with other farmers and advisers as a disadvantage of such communication patterns. As the study reveals differences in the use of communication channels during the COVID-19 pandemic by various farmers, a new communication strategy is needed that involves the use of appropriate communication channels to provide farmers with agricultural information both during the COVID-19 situation and later.
