Farming Technology Translation Profi article, 8/2015, Section: Farming Technology Health, Lowers Feed Expenses Among pig farmers, the fermentation of feed is currently noticeably under discussion because the method - besides a lowering of feed costs - also promises better animal health. But how does fermen- tation work in practice? - During the occasion of a mutual event of Weda and Schaumann, profi gained an insight into this technology. high performance pense with soy, also feed components. On the right hand side, the 2.400 I feed mixing container is situ- ated, on the left, the 750 I tank for service water. At first glance, the feed fermentation unit of Patrick and Heinrich Wilkens of the district of Oiep- holz does not seem to differ too strongly from a traditional liquid feeding system. Then, something catches one's attention: steel containers. This is where the feed for the 1,344 fattening pigs in the house behind the feed preparation is fermenting with cultivated lactic acid bacteria. As warm water is requiied for the fer- mentation, one can actually feel the pro- cess when entering the room. Thus, the Wilkens fill 3,800 I of water with a tempe- rature of 45°C into one of the two tan<s each day. The water, - brought to this temperature in a gas heater, and availab- le in two buffer tanks - causes expenses of about eight EUR daily - money, which according to Patrick Wilkens is well in- vested, fhus, since the occupation of the house in August, 2014, the fattening pigs from their own origin have reached daily gains of 910 g with a feed utilization of Currently, the development of technology :or fer- mentation towards the fermentation of pig feed is being noted with interest. At the core of this technology are always two tanks, in which feed is alternately fermenting over a period of 24 hours.

Fermented food and feedstuff Fermentation is understood as the transformation of organic substances by means of microorganisms or enzymes. This way, during the production and for preservation of foodstuff like sauerkraut, fermentation has already been made use of long before The positive side effect: The lactic acid bacteria coming into being during the pre- servation of cabbage are similar to those in the human digestive tract; thus, they support our natural immune defence. Fermented food and feedstuffs therefore have a reputation of a probiotic, and thus of a health-promoting effect....

Farming Technology Large space requirements: As far as in this case both fermenters and the buffer storage for the warm water have to be placed in the feed preparation, respective space requirement is existing. The potential of extracted rape grist is revealed in a current study of Osnabruck University. In a fattening experiment, here, soy was completely replaced by rape extraction grist in comb nation with an enzyme complex. The result: the ani- mals in the soy group yielded 99.58 kg at slaughtering; the rape group yielded With regard to the slaughtering perfor- mance, the difference was...

formulation, which can be directly given into the fermenter. The pre-cultivation ol the bacteria is therefore not necessa- ry. With regard to the price, the formula- tion of the bacteria does not play a role. Thus, in both cases, the price for the fer- mentation of one ton of feed amounts After the addition of the bacteria vac- cination into the fermenter, the lactic acid bacteria quickly start to multiply. Due to this, the pH-value rapidly de- creases. A pH-value probe, optionally available, permanently controls the pro- cess so that the fermentation process can be kept track of at the...

Farming Technology dry substance content of 29%. And once dosed out into the trough, the feed will not form sedimentations but will remain homogenous for a long time. With regard to the expenses: The fi- nancial expenditure for the fermentati- on technology of the feed is specified are each equipped with an agitator, with scales, with value device as well as with the necessary soft- tion of the feeding software "4PX'. Further tips: For keeping the costs low, also e.g., old milk or wine tanks can be used as fermenters. During running operation, however, pig farmers save money due to excess...
