“…The disposal of sludge as a fertilizer is limited and becoming economically less attractive due to the introduction of new, restrictive environmental legislation. Over the years, several experiments have been performed to investigate the possibilities of the application of flocculated industrial waste water sludge for feed (Herstad and Hvidsten, 1973;Farstad et al, 1976;Grant, 1976;El Boushy et al, 1984;De Vries and Mulder, 1986).…”

Flocculated poultry sludge was mixed with 3% molasses and was flow-therm pasteurized for 5 min at a core temperature of 95 C. The sludge was subsequently cooled to between 20 and 25 C and fermented with Lactobacillus plantarum as starter culture. Three groups of eight 8- to 10-wk-old, individually housed fattening pigs (Hypor) were fed according to a fixed scheme correlated with age. One control group received a restricted ration of commercial compound feed (Group A). The other control group was provided "nearly ad libitum" access to the same commercial compound feed (Group C). The experimental group received the same amount of commercial compound feed as Group A, but the diet was supplemented with fermented sludge, at an inclusion rate of 19 to 28% of the total ration (DM basis). The pigs fed the sludge-containing diet and those receiving the compound pig feed "nearly ad libitum" showed comparable growth results. It was concluded that the net energy (NEpig) level of .68 g DM of sludge was comparable to the NEpig level of 1 g compound pig feed (88% DM). A decrease in colony counts of Enterobacteriaceae in the intestinal tract of the pigs, was regarded as positive, as it might lower the risk of disturbance of the gut flora by enteropathogenic bacteria such as Escherichia coli and Salmonella. No adverse effects on health and performance were observed as a result of the feeding of pasteurized and subsequently fermented flocculated poultry sludge to fattening pigs. It is concluded that this sludge can serve as a valuable feed constituent as long as it is processed properly.

“…Since 1971 the biomass has been approved as livestock feed in Finland. 00710 Feeding studies (Laksesvela & Slagsvold, 1974;Alaviuhkola et al, 1975;Farstad et al, 1975) conducted with several animals such as hogs, cows, calves and poultry indicate that Pekilo biomass is nutritionally of high quality. It can therefore be expected to find extensive use as livestock feed.…”

The possible inclusion of Pekilo @ biomass, which is a dried powder produced from the filamentous microfungus Paecilomyces varioti and containing about 50% protein, in meat based food systems was evaluated using two types of sausage and meat balls as test products. The textural parameters evaluated indicated that Pekilo can form, in combination with meat, structures which are needed in these type of food systems provided that the water and fat content of the system is optimized. A comparatively strong taste owing to Pekilo was detected in these products, but it was not unanimously considered a negative factor in organoleptic analysis. Torutein and Promine D were used as reference materials in part of the sausage tests.
