Some Blood Parameters Changes for Beef Bulls in Different Seasons
Abstract: This study was carried out in a private livestock farm in Adana, located between latitudes 35 - 38 and longitudes 34 - 46 east, in 2020. Angus and Hereford breeds, aged 13 - 18 months, were studied as animal material. The aim of this study is to compare the changes in blood parameters of Angus and Hereford bulls, which are the most common fattening breeds. The healthy ones among the Hereford and Angus cattle were determined by the responsible veterinarian of the enterprise according to health symptoms such as feed consumption, lameness scores, rumination, and they were taken into separate compartments in order to determine their summer and winter values. During the experiment, the grains were kept in the same compartments and fed with a total mixture ration containing barley malt pulp, apricot pulp and corn silage. Blood samples (10 ml) were taken from the vena jugularis by the farm veterinarian. After the blood samples were kept at room temperature for 1 hour, they were incubated at 3000 rpm for 20 minutes. The serum was separated by centrifugation. Samples were stored in a deep freezer at - 20?C until analysis. Using sera from blood samples a total of 14 parameter analyzes were performed using the appropriate kit and method for each parameter in the Roche Cobas C - 501 Autoanalyzer device. BUN value were calculated using urea nitrojen content (%46). In the differences between blood protein and albumin levels of Angus and Hereford bulls, the interaction effect of breed (P<0.01), breed - season interaction was significant (P<0.01), and the seasonal effect was found to be insignificant. In the differences between blood cholesterol and triglyceride levels of Angus and Hereford bulls, the effects of breed and interaction were found to be insignificant, while the seasonal effect (P<0.05) was found to be significant. In the differences between blood glucose and BUN contents of Angus and Hereford bulls, breed and season effect (P<0.00) and interaction effect (P<0.05) were found to be significant. In terms of blood Ca content of the yearling bull, the effect of breed was insignificant in the mean difference, and the seasonal effect was found to be significant at the P<0.00 interaction level of P<0.05. In the differences between blood P and Mg contents of Angus and Hereford breeds, the effect of breed and season (P<0.00) and the interaction effect were statistically significant at P<0.05 level for P and P<0.00 for Mg. that the effect of breed and season on AST and ALP is significant at the P<0.00 level, while the interaction effect is significant only at the P<0.05 level for the difference between AST values. Statistically significant changes were detected in 5 of the 14 features discussed in this study. Changes were detected in 5 of the 14 features discussed in this study. Decrease in 7 traits and increase in 3 traits were evident, while minor differences were found in the others. The difference in the transition to summer months in the winter months is higher in the Hereford breed, which can be interpreted as the angus having less difficulty. However, it may be possible to give clear results on this subject with more detailed studies.
