Liquid pig feed mixtures consists of crushed grain and water and are mixed, pumped and measured out full automatically. Liquid feed as a rule have a high viscosity. More water of liquid feed improve the flow properties, result in more liquid manure and reduce the nutrient concentration. Different enzyme additions for reducing the feed viscosity were tested with help of a special rotational viscometer. Mixing and flow curves were measured.
Once the addition of α-amylase to liquid feed containing thermally hydrolysed starch results in a substantial reduction in the viscosity of the feed.
On the other side were the effects of a multi-enzyme-preparation for spitting of non starch polysaccharides (NSP) tested. The viscosity of barley and wheat water suspensions at pH value of < 5.3 were reduced max. 40 %. Theses problems were worked on feeding industry.
