Investigation of path analysis method in zootechnical data

This study examines the causes of the use of Path analysis in Zootechnics data and the effects of the factors given by calculation methods, which are thought to be effective in calculating, directly and indirectly, on milk efficiency. It is to determine the factor level of each of the factors on this efficiency level and to express the effects of the variables that are important, directly and indirectly. This study determined how much of the factors that have influence on milk efficiency are meaningful and identified the effects of variables that have meaningful. The most important factor that affects milk efficiency is peak efficiency. It was observed that the age factor has a direct effect on milk efficiency and is negative. The third factor directly influencing milk efficiency was found as a calf range and the direct effect of the number of days expressed from the factors affecting milk efficiency was found to be weak. According to the overall effect, peak efficiency has a strong effect on milk efficiency. It has been observed that the number of calf intervals, age and days of milking has a moderate effect on the dependent variable.
