Abstract
This study evaluated the effect of certain farming factors (period of year, feed to gain ratio and feed presentation system) on the slurry composition of growing-finishing pig farms (n=23). Feed to gain ration hardly affected chemical composition of slurry, whereas period of year only affected the organic matter content, which was lower in the hot than in the cold period. Likewise, feed presentation system showed a significant effect on some nutrient contents (organic matter, ammonium nitrogen and potassium), which were greater in wet/dry than in dry feeder type. These results highlight the importance of water and feed equipment on the excreta composition of fattening pigs.
