By-products of food industry and non food-area: Available quantities and their characterization under aspects of animal nutrition
(Landbauforschung V�lkenrode 1996, Sonderheft 169, p. 79-90)

Processing of agricultural products to foods and industrial stuffs results in large amounts of by-products. By-products may be burnt, fermented, composted, deposited or used as fertilizer. But they may be also used as feeds in animal nutrition. Prerequisites and risks of feeding of by-products are demonstrated in the paper. Amount of by-products depends on type of industrial processes. Up to 90 % of raw material may be available as by-products. About 20 % of the total feed amount come from by-products in Germany. Most important factors for characterization of by-products from the view of animal nutrition are raw materials, technological processes, content in dry matter, nutrients and energy, hygienic status, their palatability for animals and further aspects. Paper analyzed various influencing factors and conclusions for further activities are deduced.

Is the existence of biodegradable materials justifiable in diets for growing-finishing pigs ?
(Landbauforschung V�lkenrode 1999, Sonderheft 193, p. 273-278)

To evaluate the presence of a type of biodegradable material, produced on the base of maize starch (26 %) and poly-e-caprolacton (PCL, 55 %), in pig diets, the content of crude nutrients and harmful substances were determined. Additionally, the feeding value and feeding efficiency with portions of 0 %, 1 %, 5 % and 10 % of the hydrolysate were studied in digestion or feeding trials. Due to the nutrient content and their digestibility the hydrolysate was found to have an energy concentration of 7.4 MJ ME/kg DM. Under practical feeding conditions pigs did not show significant effects on growth rate, slaughter performance and meat quality, when the hydrolysate was incorporated in the diets up to 10 % (in DM). The PCL-balances showed that this component passes through the digestive tract undigested. The contents of heavy metals and PCB were found to be low. In total, arguments against the presence of this packing material in diets for pigs were not detected.
