Evaluation of vital activities in relation to selected parameters of meat performance at Czech Fleckvieh Simmental fattening bulls
Original language description
Monitoring of vital activities ("Eating", "Rumination") of cattle is currently being increasingly used for dairy cows mainly due to reproductive and welfare indicators. In contrast, they are used sporadically for growing categories (fattening bulls). Therefore, these categories need to monitor vital activities and quantify their relationship not only to welfare but also to meat performance. The experiment was carried out on 11 bulls of the Czech Fleckvieh Simmental cattle. The monitoring of vital activities was carried out in 12 weeks (from 6 to 18 weeks) of average daily gain (ADG) of 1.554 kg. Subsequently was used data from the abattoir according to EU evaluation system SEUROP, specifically carcass conformation, and fatness. The parameter "Eating" showed an average value of 276.5 minutes for U-grade, resp. 235.3 minutes for R-grade. As far as fatness is concerned, bulls classified in 2nd class reported 269.0 minutes, resp. 255.3 minutes in 3rd class. There were found correlation coefficients for carcass conformation r = 0.376, resp. for fatness r = 0.125. It was also found that the parameter "Eating" correlates with the average daily gain r = 0.359. The "Rumination" parameter showed an average value of 520.8 minutes for the U-grade and just 484.3 minutes for the R-grade. Regarding carcass fattening, bulls classified in 2nd class ruminate on average 508.1 minutes, while in 3rd class 518.0 minutes on average. Correlation coefficients were generally at a lower level of conformation r = 0.28, resp. for fatness r = 0.08. The findings confirmed that there is a positive relationship between vital activities and meat performance at the period of the beginning of the fattening bulls.
