Sažetak
Climate change characterise the current time, the fact is that we need to minimize further amplification of the same. Therefore, reduction of greenhouse gasses need to be treated as common good and imperative of every production. Short- term methods imply increase of production per animal and feeding optimisation, while long-term method imply genetic evaluation and selection based on methane emission variation. Precondition for genetic evaluation for methane emission is selection of optimal indicators and models for methane emission estimation that are highly accurate and easy applicable in routine animal recording. The objective of this research was to estimate cow’s daily dry matter intake, as necessary indicator for daily methane emission estimation, using two different equations based on animal recording data. The research results indicate that data from regular animal recording of dairy cattle that is data from milk recording and data from linear scoring could be used as indicators for estimation of body weight, based on which follows estimation of dry matter intake, which is finally basis form estimation of methane emission of dairy cows. Since body measures are characteristics of each population, aiming more accurate estimation of necessary indicators for methane emission estimation, setting the equations in our population, especially for the Holstein and for Simmental breed will be goal of our further research.
