INVESTIGATING THE ASSOCIATION BETWEEN PRE-PARTUM FEEDING AND BIRTH WEIGHT OF CROSSBRED CALVES

Abstract

In this article, it is tried to give information about the interpretation of the Cochrane Q test analysis over the somatic cell counts in milk. For this purpose, the 16 cows having single male (SM), single female (SF), twin male (TM), twin female (TF) calves at birth were selected for each season. A value of 1 was given for each data below SCC 200,000 cells/ml due to its compliance with the standards, while the ones high values from standard was assigned a value of 0 because they are not suitable for standard. Spring and summer milk with high frequency (4) in terms of non-standard milk draw attention. However, these advantages or disadvantages seen in terms of frequency number have no statistically validity. TM and TF groups have the highest frequency in terms of incompatibility with the mentioned standard. In other words, non-standard milk was mostly seen in single births regardless of gender discrimination, whereas milk suitable for the standard was mostly seen in the SM group (frequency=2). Therefore, it is seen that birth characteristics have a numerical effect on the somatic cell counts. However, it does not seem possible to say that this numerical difference on the basis of frequency is statistically significant
