Reproduction parameters and fertility control in herds of dairy cows
Perković Stevan, Vuković Dragan, Petrović Milan M.
In order to achieve good reproduction and production results in herds of dairy cows, apart from basic conditions concerning housing, care and nutrition, it is necessary to carry out regular clinical examinations of genital organs. Such examinations are not carried out regularly in practice therefore often many reproduction disorders are not diagnosed timely. As consequence we have bad fertility results, considerably lower milk production and high level of culled females from the herd. Reproduction parameters in herds of dairy cows are important factors from the aspect of successful production and herd management. Analysis of certain parameters enables the definition of problems in production, as well as the cause of bed results. Majority of this parameters can be applied in large dairy cow herds, some are also applicable in smaller herds. In conditions of market economy demands for economically efficient production are more expressed therefore the adequate determination of mentioned parameters is of great importance.
