Název v původním jazyce

Oral presentation: Analyse of non-linear Response of cooking Loss in aged Beef.

Popis výsledku v původním jazyce

We used the package nlme in program R to evaluate data from our experiment where we measured cooking loss in beef meat in aging period 2, 16, 30, 44 d post-mortem. 2x2 design (bulls, steers) x (extensively, intensively fattened) with 12 animals in each group was performed during 2 seasons. We described the relationship between aging time and cooking loss by the asymptotic regression model with three physically meaningful parameters: R0 ? the response in the (slaughter) time 0, lrc ? logarithm of the rate constant and Asym ? a response that approaches a horizontal asymptote. Factors of design (groups) were as the fixed effects, animals nested in seasons as the random effects. There were no differences between groups in R0 or lrc, only random variabilityin R0 between animals. Production system had the significant effect on the asymptote. The values were 33 % for intensive, 38 % for extensive system. The castration influenced the asymptote. Steers showed significantly lower asymptote by
