“…The first risk is that the by-products, also after rendering procedures, would carry a residual TSE infectivity (Taylor et al, 1995). The second issue arises from the nutritive value of the treated material after the intense heat treatment, usually applied to the animal waste, especially for the production of protein hydrolyzates (Piva et al, 2001;Hendriks et al, 2002Hendriks et al, , 2006. Exposure to proteins to certain processing conditions induces two major chemical changes, racemization of amino acids and formation of cross-linked amino acid (Liardon and Hurrell, 1983;Man and Bada, 1987;Friedman, 1999).…”

Re-authorization of processed animal proteins (PAPs) in EU, derived from by-products of human food production, could increase manufacturing of proteins for feed ingredients and reduce the need of imported proteins mainly of plant origin. The PAPs production is largely done by the rendering process during which authorized animal by-products are heat treated to extract valuable protein and animal fat, ensuring sterilizing conditions of raw incoming materials. Proteins exposure to certain processing conditions induces two important chemical changes, racemization of amino acids and formation of cross-linked amino acid. These changes are associated with appreciable reduction of protein digestibility and nutritional value. The aim of this study was to verify the effect of heat treatment on amino acid racemization in processed animal proteins of poultry origin and related nutritional implications by evaluation of their in vitro digestibility. The results reported confirm the detection of racemized amino acids in processed animal proteins, especially D-aspartic acid, as realistic indicators of thermal treatments during PAP manufacturing. In our results, the severe (115°C) and prolonged heat treatment (180 minutes) revealed a D-Asp content of 28.1%.Prolongation of temperature treatment (20, 30 and 180 min, at 115°C) significantly (P<0.05) affects in vitro protein digestibility, which decrease from 86.0%, in no-treated sample, to 78.3% and 79.1% after 20 and 30 min, respectively, and to 76.3% after 180 min. The processing conditions applied during PAPs preparations and the racemization of proteins amino acids may reasonably be involved in the loss of protein quality.

“…Meat and bone meal (MBM) has been widely used as a valuable protein and mineral source in diets of production animals (Hendriks et al 2002). Development of animal transmissive spongiform encephalopathies (TSE), like ovine scrapie and bovine spongiform encephalopathy (BSE) has been linked to feeding ruminants with MBM contaminated with transmissive agents (Brewer 1999).…”

Meat and bone meal (MBM) contains appreciable amounts of nitrogen (N), phosphorus and calcium making it interesting as fertilizer to various crops. The effect of Norwegian MBM as N fertilizer has been evaluated in pot and field experiments. The soils used in the pot experiment were peat and a sand/peat mixture, both low in content of plant nutrients. The field experiment was carried out on a silt loam. In the pot experiment increasing amounts of MBM gave significantly increased yields, although there was a partly N immobilisation shortly after seeding the soil based on peat organic matter. In the field experiment there was no period of N immobilisation and good N effect was found also for small amounts of MBM (Total N 50 kg ha -1 ). At total N 100 kg ha -1 there were no significant differences in grain yield of spring wheat between the treatments with MBM, mineral N fertilizer, and combination of MBM and mineral N fertilizer (N 50 kg ha -1 from each). The results indicate that the relative N efficiency of MBM compared to mineral fertilizer is 80% or higher, if MBM is applied to cereals in spring.

“…Animal source ingredients, such as the meat and bone meal (MBM), contain high levels of available P (Jeng et al, 2006) as well as other minerals. Hendriks et al (2002) reported that the mean ash content of 94 MBM samples tested was 28.4%. In comparison, plant source ingredients contain a high percentage of phytate P, which cannot be utilized by poultry.…”

Protein Source and Nutrient Density in the Diets of Male Broilers from 8 to 21 Days of Age: Effects on Tibia Dimension, Breaking Strength, and Mineral Density

The effects of supplemental protein source, and amino acid (AA) and apparent metabolizable energy (AME) densities in the diets of broilers on their growth performance and intestinal development were reported in companion studies. The effects of protein source, and AA and AME densities on the tibias of male Ross×Ross 708 broiler chicks were investigated in the current study. A completely randomized block design with a 2×2×2 factorial arrangement of treatments was applied (10 blocks, 8 treatments/block, 14 chicks/pen). Diets fed from 8 to 21 days of age (d) were formulated to contain two protein sources [high inclusion of distiller's dried grains with solubles diet (hDDGS) or high inclusion of meat and bone meal diet (hMBM)], two AA densities (moderate or high) and two AME densities (moderate or high). Tibias from 2 chicks/pen at 21 d were sampled. Chicks fed a high AA diet exhibited longer tibias than did chicks fed a moderate AA diet. Chicks fed hDDGS diets with a high AME density exhibited larger tibia circumferences as compared to those fed hMBM diets with a high AME density. Dietary treatment did not affect tibia breaking strength, ash content, or calcium, phosphorus, potassium, zinc, manganese, and magnesium concentrations in the tibia. Because feeding chicks high AME diets increased their BW, the weights of their tibia, and tibial calcium and phosphorus weights relative to BW were decreased. In birds fed high AA diets, the feeding of hMBM diets improved tibia breaking strength relative to BW when compared to the feeding of hDDGS diets. In conclusion, either hDDGS or hMBM diets can be fed to male broilers from 8 to 21 d without affecting mineral deposition in their tibias. In addition, high AME diets may improve broiler BW without affecting tibia strength.
