Comparing productivity of fertilized and unfertilized grasslands on the base of horse meat production

Abstract

The requiring of the EU, the demands for environmental and retrenchment farming, affects to decrease using fertilisers at grasslands in Hungary. Because we can hardly find any information in Hungary about the discarding of fertilisers in grasslands, therefore we started an experiment according this subject. During this experiment we compared the nutritive value, the fertility and keeping capacities of the fertilised (100 kg N, 40 kg P and 40 kg K pure ingredient/hectare/year) and unfertilised grasslands with slaughter horse during two years. In this article we are going to show the slaughter horse keeping capacities of the fertilised and unfertilised grasslands. According to our results we realised, that the gain in weight of foal was 1120 g/day on fertilised, and 1056 g/day on control plots. Estimating live weight gain and the change of the live-weight of the foals and the mares we realised that 1,7 hectare unfertilised grassland needs to reach as much product as on one hectare fertilised grassland.
