Description
The aim of the research was to analyse the role played by white clover in the improvement of economical efficiency of feeds obtained from permanent grasslands. The influence of the proportion of white clover in the pasture sward on unit production costs of yield, energy and crude protein and the profit threshold in milk production was analysed taking into account three white clover cultivars, nitrogen fertilisation, irrigation and overdrilling. The investigation procedures employed the author’s own calculation models elaborated in optimisation programs based on production conditions found in dairy farms in the region of Wielkopolska. It was proved that the role of different cultivars of white clover in reducing unit production costs of DM, NEL and CP as well as of profit threshold in milk production is greater in conditions of the absence or low level of nitrogen fertilisation and without irrigation. Among the examined cultivars, Astra was found to be the most beneficial. Overdrilling of pastures with white clover increased fodder economical efficiency more in conditions of lack of nitrogen fertilisation.
