Available Energy in Meat and Bone Meal as Measured by Different Methods

Improved prediction of meat and bone meal metabolizable energy content for ducks through in vitro methods.

Apparent metabolizable energy (AME) of meat and bone meal (MBM) for poultry is highly variable, but impractical to measure routinely. Previous efforts at developing an in vitro method for predicting AME have had limited success. The present study uses data from a previous publication on the AME of 12 MBM samples, determined using 288 White Pekin ducks, as well as composition data on these sampl...

Metabolizable energy value of meat and bone meal for pigs.

Metabolizable energy and N-corrected ME (MEn) values of 12 samples of meat and bone meal (MBM) were determined using 288 barrows with an average BW of 35 +/- 3.1 kg. For each of 12 MBM samples, diets were formulated by substituting 0, 50, or 100 g/kg MBM (as-fed basis) in a basal 170 g of CP/kg corn-soybean meal diet; corn and soybean meal were adjusted at the same ratio to account for the subs...

Meat & bone meal extract and gelatin as renewable flocculants.

Readily available proteins were tested as renewable flocculants, and their actions were compared to that of anionic PAM, a common, commercial flocculant that requires the coaddition of a calcium ion source. Two soy proteins, a whey fraction, a porcine gelatin, and a meat & bone meal (MBM) extract were used in the flocculation test. It was found that MBM extract and porcine gelatin promoted clay...

Evaluation of the Metabolizable Energy of Meat and Bone Meal for Chickens and Turkeys by Various Methods

A series of assays were conducted to determine to the available energy of several meat and bone meal products by various methods. The correct determination of the energy available to poultry from these products is important for accurate diet formulation and product usage. Several methods for determining energy availability are utilized, including true metabolizable energy (TME) and excreta and ...
