“…The lower ileal digestibility of crude fat seen in the diet containing bacterial protein meal was possibly caused by the fatty acid composition. The bacterial protein meal used contained 10% crude fat, predominantly phospholipids with large amounts of saturated fatty acids (Makula, 1978;Øverland et al, 2001). Additionally, the phospholipids in bacterial meal are tightly bound to proteins in the complex internal membrane system, and this may further reduce digestibility.…”

This study compared apparent ileal and total tract digestibility of macronutrients and amino acids in blue foxes (Alopex lagopus) fed dry extruded diets. The control diet contained fish meal as the main protein source, while in the other diets 50% of the fish meal protein was replaced by not de-hulled solvent-extracted soybean meal, meat meal or bacterial protein meal. Ileal digestibility was obtained with animals modified with ileorectal anastomosis (IRA method). There were no significant differences in the average digestibility of CP, Lys, Trp, Val, Ala or Glu between IRA modified and intact animals. Average ileal digestibilities of His, Thr, Asp, Cys, Gly, Hyp, Pro, Ser, starch and total carbohydrates (CHO) were significantly lower compared with total tract values. Average ileal digestibility of Arg, Ile, Leu, Met, Phe, Tyr and crude fat was significantly higher than total tract digestibility. Digestibility measured in IRA modified animals showed less variability compared with values from intact animals. There were significant differences among diets in ileal as well as total tract digestibility of orude protein, most amino acids, starch and CHO, and in ileal digestibility of crude fat. Ileal crude protein digestibility of the diets ranged from 81.0-86.4% and total tract digestibility from 82.5-86.4%. Ileal amino acid digestibilities ranged from 70.1 (Asp) to 93.3% (Arg) and total tract values ranged from 72.8 (Cys) to 92.2% (Arg). Both ileal and total tract digestibilities of crude protein and most amino acids were significantly lower for diets containing meat meal or bacterial protein meal compared with the control fish meal-based diet and the diet with soybean meal. Although ileal digestibility may be more accurate than total tract digestibility in estimating the protein and amino acid supply in blue foxes, total tract digestibility may be acceptable because of numerically small differences between ileal and total tract digestibilities for protein and most amino acids. It was further concluded that ileal digestibilities of starch and CHO in the blue fox are lower than corresponding total tract digestibilities.

“…Growth trials suggest that BPM may be a promising alternative protein source, but some varying and contradictory results have been observed (Øverland et al, 2001 andSkrede et al, 2003;Storebakken et al, 2004). Dietary BPM providing up to one-third of the N intake was found to sustain animal performance and health in slaughter chickens (Skrede et al, 2003) and blue foxes (Skrede and Ahlstrøm, 2002).…”

“…Previous production experiments with BPM in diets for monogastric species (Øverland et al, 2001 andSkrede and Ahlstrøm, 2002;Skrede et al, 2003;Storebakken et al, 2004), and N and energy metabolism studies in mink and chickens (Hellwing et al, 2005 and2006), have given somewhat varying and contradictory results. Therefore, the objective of the present study was, by means of balance and respiration experiments, to reveal effects of replacement of SBM by BPM on N and energy metabolism in balanced diets for growing-finishing pigs.…”

This experiment investigated the effects of increasing the dietary content of bacterial protein meal (BPM) on the protein and energy metabolism of pigs from weaning to a live weight of 80 kg. Four litters with four castrated male pigs in each litter were used. The litters were divided into two blocks according to age. One pig from each litter was fed one of the four experimental diets. Soya-bean meal was replaced with BPM on the basis of digestible protein, and the BPM contents in the four diets were 0% (BP0), 5% (BP5), 10% (BP10) and 15% (BP15), corresponding to 0%, 17%, 35% and 52% of the digestible nitrogen (N), respectively. Four balance periods were performed, at the start of which the pigs weighed 9.5 kg, 20.7 kg, 45.3 kg and 77.2 kg, respectively. Once during each balance period, 22-h respiration experiments were performed using indirect calorimetry. Daily weight gain, feed intake and feed conversion rate were the same for all diets. The apparent digestibility of N was lower on diet BP10 than on BP0 (P ¼ 0.002), whereas the apparent digestibility of energy was similar on all diets. The retention of nitrogen did not differ between diets and was 1.50, 1.53, 1.33 and 1.46 g N per kg 0.75 per day on BP0, BP5, BP10 and BP15, respectively. Neither metabolisable energy intake nor heat production were affected by inclusion level of BPM. Retention of energy was 620 (BP0), 696 (BP5), 613 (BP10) and 664 kJ/kg 0.75 per day (BP15), the differences among diets being non-significant. The N-free respiratory quotient was similar on all diets. It was concluded that the overall protein and energy metabolism in growing pigs were not affected when up to 50% of dietary N was derived from BPM.

“…The dried microbial product consists of 70% crude protein, 10% crude fat and 7% crude ash) [6]. BPM can supply up to 40% of dietary nitrogen requirement in growing-finishing pigs [7], 40% of dietary nitrogen in Atlantic salmon [8] and 33% of dietary nitrogen in broiler chicken [9] without any adverse effect on growth performance. However, increasing the BPM diet up to 48% of dietary nitrogen in piglets resulted in reduced daily weight gain and increased feed to gain ratio, but this has been attributed to marginal lysine deficiency rather than the effect of BPM per se [4].…”

In an 84 days feeding trial, the effect of feeding bacterial protein meal (BPM) either as a replacement for fish meal or for groundnut cake meal in growing rabbits was examined. A total of 20 growing rabbits having an initial body weight of 617.2 (standard error 25) g were randomly assigned to five dietary treatments. A control diet based mainly on agro-industrial by-product palm kernel meal was formulated to meet the nutrient requirement of growing rabbits. Other conventional protein and energy rich ingredients such as maize, groundnut cake (GNC) and fish meal (FM) were included as composite at levels up to 17% of the weight. Bacterial protein meal (Streptomyces sp., species not specified by the manufacturer) with a crude protein, fat and fibre content of 70, 6.5 and 4.1%, respectively was added to the control diet (diet I) either as a replacement for FM at 0, 20 and 40 g/kg in diets I, II and III or as a replacement for GNC at 34 and 68 g/kg in diets IV and V, respectively. Each diet was offered to four rabbits housed individually in raised metal hutches with wire screen floors with each hutch representing an experimental unit. The rabbits were individually weighed on a weekly basis until the end of the experiment. Water and feed were supplied ad libitum and daily voluntary feed intake was monitored. Growing rabbits responded non-significantly (p> 0.05) in feed intake, body weight gain and feed conversion to BPM as a replacement for either FM or GNC over the 84 days of experiment. Six rabbits (3 rabbits from each treatment) on diet I (zero inclusion of BPM) and diet V (highest level of BPM inclusion) were slaughtered at 12 weeks to determine carcass composition. The inclusion of BPM in diet V reduced the skin weight significantly (p<0.004) and kidney fat weight (p<0.067), while dressing percentage and other carcass indices were not significantly (p>0.05) affected. It was concluded that BPM can completely (to 100 %) replace FM and GNC in the diet of growing rabbits. BPM also reduced kidney fat content (which is an index of carcass fatness). BPM can be fed (up to 6.8% of the total diet) to 5 -6 weeks old rabbits through finishing with no adverse effect on growth or carcass characteristics.
