Beurteilung der Funktionsfähigkeit einer Fütterungsanlage mit pneumatischer Futterverteilung

The functional capability of the feeder can play a pivotal role in providing essential nutrients for animals according to the requirement. Therefore, the functional capability of the feeder in a commercial pig farm was evaluated using the error of dosage, the error of adjustment, the error of mixing, the repeatability and the carry over of the feeder. The error of dosage and the error of adjustement did not exceed 6 %. Dosing 300 g and 600 g of feed, for calcium an error of mixing of 33 and 15 % was found respectively. Dosing 4000 g of feed the error of mixing was reduced to 8 %. For the carry over of calcium 30.53 % were found. For magnesium and phosphorus the error of mixing and the carry over indicated an almost homogenous mixing process and a minimized contamination of the feed.
