Apparent digestibility of Mediterranean forages determined by total collection of faeces and acid-insoluble ash as internal marker.
Brief content of the article
The characteristics of the Mediterranean forages used in Italy could determine some differences between their energy values and the data of other similar forages listed in the table values of INRA; an accurate determination of at least organic matter digestibility must be performed. The authors wrote that for the determination of apparent digestibility coefficients, the total collection method, that is the reference method in the French system, could be replaced by the more easy internal markers method using acid insoluble ash (AIA). In this study the authors compared and discussed the use of these two methods by calculating apparent digestibility rates of some Mediterranean forages. The results indicated that for digestibility coefficients fast assessments, the AIA method can be considered suitable, but for the introduction of Mediterranean forages in the French nutritive value tables of feeds for horses the total collection method must be considered the correct choice.
