Nutritive Value of the Meat and Bone Meals from Cattle or Pigs in Broiler Diets

ABSTRACT The nutritive value of meat and bone meals (MBM) was assessed for broilers. The MBM was produced according to the revised (pressure) processing system or-dered by the European Union (EC 96/449). Three batches of MBM from cattle (MBMcattle) and three from pigs (MBMpig) with different ash contents (224, 306, 387, and 209, 293, 430 g/kg, respectively) were tested for digestibil-ity at a 10 % inclusion level. The MBMcattle and MBMpig with the lowest ash (224 and 209 g/kg, respectively) were tested also at 20 % inclusion. A basal diet (corn-soybean meal) was used as a control. Two-week-old broiler chick-ens were used in four replicates per treatment (14 to 32 d of age). The AMEn of MBM was high (10.51 to 13.04 MJ/ kg DM). Species origin had no significant effect, whereas (Key words: meat and bone meal, amino acid, excretal and ileal digestibility, metabolizable energy, broiler
