The influence of meat-and-bone meal and exogenous phytase on growth performance, bone mineralisation and digestibility coefficients of protein (N), amino acids and starch in broiler chickens
Published: May 18, 2017
Summary
1. Introduction Meat-and-bone meal (MBM) is a potential source of protein, calcium and phosphorus in poultry diets for some parts of the world, including Australia, China and Southeast Asia. However, there are considerable variations in its protein quality and Ca and P concentrations. Ravindran et al. (2002) reported substantial variations in ash (13.0e56.5 g/100 g), crude protein (38.5e67.2 g...

I think something went wrong with amino acid analysis of the finisher diets in this article.
Looking towards the Glycine and Proline concentrations is the diets number 5 and 6.
It seems that these samples are switched or something like that, because you will have an contineous increase of Gly and Pro and a contineous decrease of Asp when you exchange soybean meal by meat-and- bonemeal. If these results are used for calculations of the AA digestibility this will have impact on the presented results

Measuring and projecting performance allows you to choose the feeding strategy that reduces the feed costs and, as a result, gives the best chances for increasing profitability. After all, you can only improve what you can measure.
