Liquid feed hygiene
When using liquid feed in pig fattening and piglet production, the success is, to a great extent, dependent on the feed hygiene. It is more difficult to control the feed hygiene in liquid feed facilities compared with dry or mash feeders. In particular, the problem zones are the mixing vat, storage tank for products such as CCM and water, the transport pipe and the feed outlets in the trough. It is precisely in the moist environments that germs find exceptional multiplication conditions in high surrounding and/or stable temperatures.
Undesired micro-organisms in the liquid feed are yeasts, mould and bacteria. They deteriorate the animals' health and the economic results in pig fattening and piglet production through their degradation products in large quantities. Due to the named conditions, daily cleaning of the mixing vats and a thorough clean of the liquid feed facilities are necessary at regular intervals.
